Not sure why no one mentioned to just use the built-in sticky header style for elements. Worked great for me.
.tableContainerDiv {
overflow: auto;
max-height: 80em;
}
th {
position: sticky;
top: 0;
background: white;
}
Put a min-width on the in @media if you need to make responsive (or similar).
see Table headers position:sticky or Position Sticky and Table Headers
A general and simple function to use:
def truncate_float(number, length):
"""Truncate float numbers, up to the number specified
in length that must be an integer"""
number = number * pow(10, length)
number = int(number)
number = float(number)
number /= pow(10, length)
return number
To achieve this there are basically two methods which I frequently use:
1. Using the cursor escape character (\c
) with echo -e
Example :
for i in {0..10..2}; do
echo -e "$i \c"
done
# 0 2 4 6 8 10
-e
flag enables the Escape characters in the string. \c
brings the Cursor back to the current line.OR
2. Using the printf
command
Example:
for ((i = 0; i < 5; ++i)); do
printf "$i "
done
# 0 1 2 3 4
Quote: I would like to know how to display the div in the middle of the screen, whether user has scrolled up/down.
Change

It sounds like you understand how interfaces work but are unsure of when to use them and what advantages they offer. Here are a few examples of when an interface would make sense:
// if I want to add search capabilities to my application and support multiple search
// engines such as Google, Yahoo, Live, etc.
interface ISearchProvider
{
string Search(string keywords);
}
then I could create GoogleSearchProvider, YahooSearchProvider, LiveSearchProvider, etc.
// if I want to support multiple downloads using different protocols
// HTTP, HTTPS, FTP, FTPS, etc.
interface IUrlDownload
{
void Download(string url)
}
// how about an image loader for different kinds of images JPG, GIF, PNG, etc.
interface IImageLoader
{
Bitmap LoadImage(string filename)
}
then create JpegImageLoader, GifImageLoader, PngImageLoader, etc.
Most add-ins and plugin systems work off interfaces.
Another popular use is for the Repository pattern. Say I want to load a list of zip codes from different sources
interface IZipCodeRepository
{
IList<ZipCode> GetZipCodes(string state);
}
then I could create an XMLZipCodeRepository, SQLZipCodeRepository, CSVZipCodeRepository, etc. For my web applications, I often create XML repositories early on so I can get something up and running before the SQL Database is ready. Once the database is ready I write an SQLRepository to replace the XML version. The rest of my code remains unchanged since it runs solely off of interfaces.
Methods can accept interfaces such as:
PrintZipCodes(IZipCodeRepository zipCodeRepository, string state)
{
foreach (ZipCode zipCode in zipCodeRepository.GetZipCodes(state))
{
Console.WriteLine(zipCode.ToString());
}
}
You have a typo in the import in your LoginComponent
's file
import { Component } from '@angular/Core';
It's lowercase c
, not uppercase
import { Component } from '@angular/core';
if you are using jQuery to send AJAX Posts, add this code to all views:
$( document ).on( 'ajaxSend', addLaravelCSRF );
function addLaravelCSRF( event, jqxhr, settings ) {
jqxhr.setRequestHeader( 'X-XSRF-TOKEN', getCookie( 'XSRF-TOKEN' ) );
}
function getCookie(name) {
function escape(s) { return s.replace(/([.*+?\^${}()|\[\]\/\\])/g, '\\$1'); };
var match = document.cookie.match(RegExp('(?:^|;\\s*)' + escape(name) + '=([^;]*)'));
return match ? match[1] : null;
}
Laravel adds a XSRF cookie to all requests, and we automatically append it to all AJAX requests just before submit.
You may replace getCookie function if there is another function or jQuery plugin to do the same thing.
lsof -P | grep ':3000' | awk '{print $2}'
This will give you just the pid, tested on MacOS.
Remove the data attribute as you are not POSTING
anything to the server (Your controller does not expect any parameters).
And in your AJAX Method you can use Razor
and use @Url.Action
rather than a static string:
$.ajax({
url: '@Url.Action("FirstAjax", "AjaxTest")',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: successFunc,
error: errorFunc
});
From your update:
$.ajax({
type: "POST",
url: '@Url.Action("FirstAjax", "AjaxTest")',
contentType: "application/json; charset=utf-8",
data: { a: "testing" },
dataType: "json",
success: function() { alert('Success'); },
error: errorFunc
});

In response to some comments asking questions about the behaviour of Arrays.asList() since Java 8:
int[] arr1 = {1,2,3};
/*
Arrays are objects in Java, internally int[] will be represented by
an Integer Array object which when printed on console shall output
a pattern such as
[I@address for 1-dim int array,
[[I@address for 2-dim int array,
[[F@address for 2-dim float array etc.
*/
System.out.println(Arrays.asList(arr1));
/*
The line below results in Compile time error as Arrays.asList(int[] array)
returns List<int[]>. The returned list contains only one element
and that is the int[] {1,2,3}
*/
// List<Integer> list1 = Arrays.asList(arr1);
/*
Arrays.asList(arr1) is Arrays$ArrayList object whose only element is int[] array
so the line below prints [[I@...], where [I@... is the array object.
*/
System.out.println(Arrays.asList(arr1));
/*
This prints [I@..., the actual array object stored as single element
in the Arrays$ArrayList object.
*/
System.out.println(Arrays.asList(arr1).get(0));
// prints the contents of array [1,2,3]
System.out.println(Arrays.toString(Arrays.asList(arr1).get(0)));
Integer[] arr2 = {1,2,3};
/*
Arrays.asList(arr) is Arrays$ArrayList object which is
a wrapper list object containing three elements 1,2,3.
Technically, it is pointing to the original Integer[] array
*/
List<Integer> list2 = Arrays.asList(arr2);
// prints the contents of list [1,2,3]
System.out.println(list2);
I know my answer it's too late, but it might helpful to other's
Try,
Void Main()
{
string filename = @"test.txt";
string filePath= AppDomain.CurrentDomain.BaseDirectory + filename ;
Console.WriteLine(filePath);
}
$(document).ready(function () {

**OR**
$(document).ready(function() {

You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.
According to the page:
This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.
Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.
Just put the html tags with there content and add the xmlns attribute with quotes after the equals and in between the quotes is http://www.w3.org/1999/xhtml
If you want to increase the height of the input field, you can specify line-height
css property for the input field.

I had the same problem. Even after updating the password using sudo passwd it was not working. I had to give "multiple" roles for my user through IAM & Admin Refer Screen Shot on IAM & Admin screen of google cloud
After that i restarted the VM. Then again changed the password and then it worked.
user1@sap-hanaexpress-public-1-vm:~> sudo passwd
New password:
Retype new password:
passwd: password updated successfully
user1@sap-hanaexpress-public-1-vm:~> su
Password:

Note that as of Gson 2.8.6, instance method JsonParser.parse
has been deprecated and replaced by static method JsonParser.parseString
:
JsonObject jsonObject = JsonParser.parseString(json).getAsJsonObject();
To accomplish this in all browsers you need to use a combination of @energee, @Richard and @Feuermurmel methods.
<a href="" style="display: block; z-index: 1;">
<object data="" style="z-index: -1; pointer-events: none;" />
</a>
Adding:
pointer-events: none;
makes it work in Firefox.display: block;
gets it working in Chrome, and Safari.z-index: 1; z-index: -1;
makes it work in IE as well.There's no need to check the exit code explicitly. Try
if getent passwd $1 > /dev/null 2>&1; then
echo "yes the user exists"
else
echo "No, the user does not exist"
fi
If that doesn't work, there is something wrong with your getent
, or you have more users defined than you think.
You can move your proxy authentication and ssl staff to soap handler
port = new SomeService().getServicePort();

It use UrlConnection, you can use any library you want in handler. Have fun!
You could use GSON, using Gradle Build.gradle :
implementation 'com.google.code.gson:gson:2.8.0'
Then in your code, for example pairs of string/boolean with Kotlin :
val nestedData = HashMap<String,Boolean>()
for (i in 0..29) {
nestedData.put(i.toString(), true)
}
val gson = Gson()
val jsonFromMap = gson.toJson(nestedData)
Adding to SharedPrefs :
val sharedPrefEditor = context.getSharedPreferences(_prefName, Context.MODE_PRIVATE).edit()
sharedPrefEditor.putString("sig_types", jsonFromMap)
sharedPrefEditor.apply()
Now to retrieve data :
val gson = Gson()
val sharedPref: SharedPreferences = context.getSharedPreferences(_prefName, Context.MODE_PRIVATE)
val json = sharedPref.getString("sig_types", "false")
val type = object : TypeToken<Map<String, Boolean>>() {}.type
val map = gson.fromJson(json, type) as LinkedTreeMap<String,Boolean>
for (key in map.keys) {
Log.i("myvalues", key.toString() + map.get(key).toString())
}
You need to look for some replaceAll option
str = str.replace(/ /g, "+");
this is a regular expression way of doing a replaceAll.
function ReplaceAll(Source, stringToFind, stringToReplace) {
var temp = Source;
var index = temp.indexOf(stringToFind);
while (index != -1) {
temp = temp.replace(stringToFind, stringToReplace);
index = temp.indexOf(stringToFind);
}
return temp;
}
String.prototype.ReplaceAll = function (stringToFind, stringToReplace) {
var temp = this;
var index = temp.indexOf(stringToFind);
while (index != -1) {
temp = temp.replace(stringToFind, stringToReplace);
index = temp.indexOf(stringToFind);
}
return temp;
};
If you want a single JavaScript object such as the following:
{ uniqueIDofSelect: "uniqueID", optionValue: "2" }
(where option 2, "Absent", is the current selection) then the following code should produce it:
var jsObj = null;
var status = document.getElementsByName("status")[0];
for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsObj = { uniqueIDofSelect: status.id, optionValue: options[i].value };
break;
}
}
If you want an array of all such objects (not just the selected one), use michael's code but swap out status.options[i].text
for status.id
.
If you want a string that contains a JSON representation of the selected object, use this instead:
var jsonStr = "";
var status = document.getElementsByName("status")[0];
for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsonStr = '{ '
+ '"uniqueIDofSelect" : '
+ '"' + status.id + '"'
+ ", "
+ '"optionValue" : '
+ '"'+ options[i].value + '"'
+ ' }';
break;
}
}
Why are you using a List if you want to initialize it with a fixed value ? I can understand that -for the sake of performance- you want to give it an initial capacity, but isn't one of the advantages of a list over a regular array that it can grow when needed ?
When you do this:
List<int> = new List<int>(100);
You create a list whose capacity is 100 integers. This means that your List won't need to 'grow' until you add the 101th item. The underlying array of the list will be initialized with a length of 100.
If you don't specify indexes on your initial array, you get the regular numric ones. Arrays must have some form of unique index
All you need is a reluctant quantifier:
regex: /aa.*?aa/
aabbabcaabda => aabbabcaa
aaaaaabda => aaaa
aabbabcaabda => aabbabcaa
aababaaaabdaa => aababaa, aabdaa
You could use negative lookahead, too, but in this case it's just a more verbose way accomplish the same thing. Also, it's a little trickier than gpojd made it out to be. The lookahead has to be applied at each position before the dot is allowed to consume the next character.
/aa(?:(?!aa).)*aa/
As for the approach suggested by Claudiu and finnw, it'll work okay when the sentinel string is only two characters long, but (as Claudiu acknowledged) it's too unwieldy for longer strings.
Another reason of this problem can be column type of "payload" sessions table. If you have huge data on session, a text column wouldn't be enough. You will need MEDIUMTEXT or even LONGTEXT.
There are workarounds but no clean/short/sweet way to do it with streams and to be honest, you would probably be better off with:
int idx = 0;
for (Param p : params) query.bind(idx++, p);
Or the older style:
for (int idx = 0; idx < params.size(); idx++) query.bind(idx, params.get(idx));
DateFormat formatter;

USING PHP, HTML AND JAVASCRIPT for prompting
Just if someone looking for using php, html and javascript in a single file, the answer below is working for me.. i attached with the used of bootstrap icon "trash" for the link.
<a class="btn btn-danger" href="<?php echo "delete.php?&var=$var"; ?>" onclick="return confirm('Are you sure want to delete this?');"><span class="glyphicon glyphicon-trash"></span></a>
the reason i used php code in the middle is because i cant use it from the beginning..
the code below doesnt work for me:-
echo "<a class='btn btn-danger' href='delete.php?&var=$var' onclick='return confirm('Are you sure want to delete this?');'><span class='glyphicon glyphicon-trash'></span></a>";
and i modified it as in the 1st code then i run as just what i need.. I hope that can i can help someone inneed of my case.
The following statement appends the value to the element with the id of response
$('#response').append(total);
This makes it look like you are concatenating the strings, but you aren't, you're actually appending them to the element
change that to
$('#response').text(total);
You need to change the drop event so that it replaces the value of the element with the total, you also need to keep track of what the total is, I suggest something like the following
$(function() {
var data = [];
var total = 0;
$( "#draggable1" ).draggable();
$( "#draggable2" ).draggable();
$( "#draggable3" ).draggable();
$("#droppable_box").droppable({
drop: function(event, ui) {
var currentId = $(ui.draggable).attr('id');
data.push($(ui.draggable).attr('id'));
if(currentId == "draggable1"){
var myInt1 = parseFloat($('#MealplanCalsPerServing1').val());
}
if(currentId == "draggable2"){
var myInt2 = parseFloat($('#MealplanCalsPerServing2').val());
}
if(currentId == "draggable3"){
var myInt3 = parseFloat($('#MealplanCalsPerServing3').val());
}
if ( typeof myInt1 === 'undefined' || !myInt1 ) {
myInt1 = parseInt(0);
}
if ( typeof myInt2 === 'undefined' || !myInt2){
myInt2 = parseInt(0);
}
if ( typeof myInt3 === 'undefined' || !myInt3){
myInt3 = parseInt(0);
}
total += parseFloat(myInt1 + myInt2 + myInt3);
$('#response').text(total);
}
});
$('#myId').click(function(event) {
$.post("process.php", ({ id: data }), function(return_data, status) {
alert(data);
//alert(total);
});
});
});
I moved the var total = 0;
statement out of the drop event and changed the assignment statment from this
total = parseFloat(myInt1 + myInt2 + myInt3);
to this
total += parseFloat(myInt1 + myInt2 + myInt3);
Here is a working example http://jsfiddle.net/axrwkr/RCzGn/
The following format should work:
$.ajax({
type: "POST",
url: "@Url.Action("refresh", "group")",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({
myDate: '2011-04-02 17:15:45'
}),
success: function (result) {
//do something
},
error: function (req, status, error) {
//error
}
});
... takes no arguments and has a void return type?
If you are writing for System.Windows.Forms
, You can also use:
public delegate void MethodInvoker()
Add this to your NodeJS Server below imports:
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
To show:
<img src="//graph.facebook.com/{{fid}}/picture">
<img src="//graph.facebook.com/{{fid}}/picture?type=large">
NOTE: Don't use this. See @Foreever's comment below.
$img = file_get_contents('https://graph.facebook.com/'.$fid.'/picture?type=large');
$file = dirname(__file__).'/avatar/'.$fid.'.jpg';
file_put_contents($file, $img);
Where $fid is your user id on Facebook.
NOTE: In case of images marked as "18+" you will need a valid access_token from a 18+ user:
<img src="//graph.facebook.com/{{fid}}/picture?access_token={{access_token}}">
Graph API v2.0 can't be queried using usernames, you should use userId
always.
It may be late. It is Happen because your git HEAD is not updated.
this commend would solve that git reset HEAD
.
Use some regex like [0-9]
or \d
:
$words = preg_replace('/\d+/', '', $words );
You might want to read the preg_replace() documentation as this is directly shown there.
Example for String Methods
Given a list of filenames, we want to rename all the files with extension hpp to the extension h. To do this, we would like to generate a new list called newfilenames, consisting of the new filenames. Fill in the blanks in the code using any of the methods you’ve learned thus far, like a for loop or a list comprehension.
filenames = ["program.c", "stdio.hpp", "sample.hpp", "a.out", "math.hpp", "hpp.out"]
# Generate newfilenames as a list containing the new filenames
# using as many lines of code as your chosen method requires.
newfilenames = []
for i in filenames:
if i.endswith(".hpp"):
x = i.replace("hpp", "h")
newfilenames.append(x)
else:
newfilenames.append(i)
print(newfilenames)
# Should be ["program.c", "stdio.h", "sample.h", "a.out", "math.h", "hpp.out"]
I recommend XML reader/writer class for files because it is easily serialized.
Serialization (known as pickling in python) is an easy way to convert an object to a binary representation that can then be e.g. written to disk or sent over a wire.
It's useful e.g. for easy saving of settings to a file.
You can serialize your own classes if you mark them with
[Serializable]
attribute. This serializes all members of a class, except those marked as[NonSerialized]
.
The following is code to show you how to do this:
using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
namespace ConfigTest
{ [ Serializable() ]
public class ConfigManager
{
private string windowTitle = "Corp";
private string printTitle = "Inventory";
public string WindowTitle
{
get
{
return windowTitle;
}
set
{
windowTitle = value;
}
}
public string PrintTitle
{
get
{
return printTitle;
}
set
{
printTitle = value;
}
}
}
}
You then, in maybe a ConfigForm, call your ConfigManager class and Serialize it!
public ConfigForm()
{
InitializeComponent();
cm = new ConfigManager();
ser = new XmlSerializer(typeof(ConfigManager));
LoadConfig();
}
private void LoadConfig()
{
try
{
if (File.Exists(filepath))
{
FileStream fs = new FileStream(filepath, FileMode.Open);
cm = (ConfigManager)ser.Deserialize(fs);
fs.Close();
}
else
{
MessageBox.Show("Could not find User Configuration File\n\nCreating new file...", "User Config Not Found");
FileStream fs = new FileStream(filepath, FileMode.CreateNew);
TextWriter tw = new StreamWriter(fs);
ser.Serialize(tw, cm);
tw.Close();
fs.Close();
}
setupControlsFromConfig();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
After it has been serialized, you can then call the parameters of your config file using cm.WindowTitle, etc.
First, try changing <a>Link</a>
to <span id=test><a>Link</a></span>
.
Then, add something like this in the javascript function that you're calling:
var abc = 'somelink';
document.getElementById('test').innerHTML = '<a href="' + abc + '">Link</a>';
This way the link will look like this:
<a href="somelink">Link</a>
@S-Lott gives the right procedure, but expanding on the Unicode issues, the Python interpreter can provide more insights.
Jon Skeet is right (unusual) about the codecs
module - it contains byte strings:
>>> import codecs
>>> codecs.BOM
'\xff\xfe'
>>> codecs.BOM_UTF8
'\xef\xbb\xbf'
>>>
Picking another nit, the BOM
has a standard Unicode name, and it can be entered as:
>>> bom= u"\N{ZERO WIDTH NO-BREAK SPACE}"
>>> bom
u'\ufeff'
It is also accessible via unicodedata
:
>>> import unicodedata
>>> unicodedata.lookup('ZERO WIDTH NO-BREAK SPACE')
u'\ufeff'
>>>
Oracle has two different ways of making views updatable:-
I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.
Here's what I cooked up. It's pretty simple, but it works:
function eventFire(el, etype){
if (el.fireEvent) {
el.fireEvent('on' + etype);
} else {
var evObj = document.createEvent('Events');
evObj.initEvent(etype, true, false);
el.dispatchEvent(evObj);
}
}
Usage:
eventFire(document.getElementById('mytest1'), 'click');
Suppose you need only x:target/classes in your classpath. Then you just add this folder to your classpath and %IDEA%\lib\idea_rt.jar. Now it will work. That's it.
You can use os.listdir
for this purpose. If you only want files and not directories, you can filter the results using os.path.isfile
.
example:
files = os.listdir(os.curdir) #files and directories
or
files = filter(os.path.isfile, os.listdir( os.curdir ) ) # files only
files = [ f for f in os.listdir( os.curdir ) if os.path.isfile(f) ] #list comprehension version.
If you're using the org.apache.poi.ss.usermodel (not HSSF or XSSF) you can use:
style.setBorderBottom(BorderStyle.THIN);
style.setBorderTop(BorderStyle.THIN);
style.setBorderLeft(BorderStyle.THIN);
style.setBorderRight(BorderStyle.THIN);
all the border styles are here at the apache documentation
Maybe this helps:
and run devenv /resetuserdata
.
Expect, that all of your user settings such as Visual Studio layout, linked Microsoft account or start page might disappear.
You need to JSON.parse()
the string.
var str = '{"hello":"world"}';
try {
var obj = JSON.parse(str); // this is how you parse a string into JSON
document.body.innerHTML += obj.hello;
} catch (ex) {
console.error(ex);
}

A dictionary probably isn't what you should be using in this case. A more full featured library would be a better alternative. Probably a real database. The easiest would be sqlite. You can keep the whole thing in memory by passing in the string ':memory:' instead of a filename.
If you do want to continue down this path, you can do it with the extra attributes in the key or the value. However a dictionary can't be the key to a another dictionary, but a tuple can. The docs explain what's allowable. It must be an immutable object, which includes strings, numbers and tuples that contain only strings and numbers (and more tuples containing only those types recursively...).
You could do your first example with d = {('apple', 'red') : 4}
, but it'll be very hard to query for what you want. You'd need to do something like this:
#find all apples
apples = [d[key] for key in d.keys() if key[0] == 'apple']
#find all red items
red = [d[key] for key in d.keys() if key[1] == 'red']
#the red apple
redapples = d[('apple', 'red')]
It can also be due to a duplicate entry in any of the tables that are used.
<input type="button" />
buttons will not submit a form - they don't do anything by default. They're generally used in conjunction with JavaScript as part of an AJAX application.
<input type="submit">
buttons will submit the form they are in when the user clicks on them, unless you specify otherwise with JavaScript.
For future reference, you can quickly create a truth table to check if it evaluates the way you want... it's kind of like Sudoku.
(!isset($action)) && ($action != "add" && $action != "delete"))
Example:
column 1 is issetaction, column 2 and 3 evaluates !="add","delete" respectively
if($a=add) T && (F && T) => T && F => FALSE
if($a=delete) T && (T && F) => T && F => FALSE
if($a=nothing) T && (T && T) => T && T => TRUE
Yes, that is supported.
Check the documentation provided here for the supported keywords inside method names.
You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:
List<Inventory> findByIdIn(List<Long> ids);
I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:
The Entity
@Entity
public class Inventory implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
// other fields
// getters/setters
}
The Repository
@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {
List<Inventory> findByIdIn(List<Long> ids);
}
As an additional note, there is no need for the for loop because of R's vectorization.
This:
P <- 243.51
t <- 31 / 365
n <- 365
for (r in seq(0.15, 0.22, by = 0.01))
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P
}
is equivalent to:
P <- 243.51
t <- 31 / 365
n <- 365
r <- seq(0.15, 0.22, by = 0.01)
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P
Because r
is a vector, the expression above containing it is performed for all values of the vector.
You can't, but you can print 0 or 1
_Bool b = 1;
printf("%d\n", b);
In python this work for me
self.set_your_value = "your value"

from PIL import Image
import os, os.path
imgs = []
path = "/home/tony/pictures"
valid_images = [".jpg",".gif",".png",".tga"]
for f in os.listdir(path):
ext = os.path.splitext(f)[1]
if ext.lower() not in valid_images:
continue
imgs.append(Image.open(os.path.join(path,f)))
Use os.path.join
to concatenate the directory and file name:
for path, subdirs, files in os.walk(root):
for name in files:
print(os.path.join(path, name))
Note the usage of path
and not root
in the concatenation, since using root
would be incorrect.
In Python 3.4, the pathlib module was added for easier path manipulations. So the equivalent to os.path.join
would be:
pathlib.PurePath(path, name)
The advantage of pathlib
is that you can use a variety of useful methods on paths. If you use the concrete Path
variant you can also do actual OS calls through them, like changing into a directory, deleting the path, opening the file it points to and much more.
import os
exec_filepath = os.path.realpath(__file__)
exec_dirpath = exec_filepath[0:len(exec_filepath)-len(os.path.basename(__file__))]
Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" )
. After the required positional arguments, you can specify specific optional arguments by name.
You can execute below code
SELECT Time FROM [TableName] where DATEPART(YYYY,[Time])='2018' and DATEPART(MM,[Time])='06' and DATEPART(DD,[Time])='14
I had the same problem as you do and I could solve it by following @CarlosRojas instructions with a little difference. Instead of create a new firewall rule I edited the default-allow-internal
one to accept traffic from anywhere since creating new rules didn't make any difference.
I've written a personal library that allows you to order by multiple values, with all the ordering done on the server.
Querybase takes in a Firebase Database Reference and an array of fields you wish to index on. When you create new records it will automatically handle the generation of keys that allow for multiple querying. The caveat is that it only supports straight equivalence (no less than or greater than).
const databaseRef = firebase.database().ref().child('people');
const querybaseRef = querybase.ref(databaseRef, ['name', 'age', 'location']);
// Automatically handles composite keys
querybaseRef.push({
name: 'David',
age: 27,
location: 'SF'
});
// Find records by multiple fields
// returns a Firebase Database ref
const queriedDbRef = querybaseRef
.where({
name: 'David',
age: 27
});
// Listen for realtime updates
queriedDbRef.on('value', snap => console.log(snap));
The suggestions to use cookies aside, the only comprehensive set of identifying attributes available to interrogate are contained in the HTTP request header. So it is possible to use some subset of these to create a pseudo-unique identifier for a user agent (i.e., browser). Further, most of this information is possibly already being logged in the so-called "access log" of your web server software by default and, if not, can be easily configured to do so. Then, a utlity could be developed that simply scans the content of this log, creating fingerprints of each request comprised of, say, the IP address and User Agent string, etc. The more data available, even including the contents of specific cookies, adds to the quality of the uniqueness of this fingerprint. Though, as many others have stated already, the HTTP protocol doesn't make this 100% foolproof - at best it can only be a fairly good indicator.
Those are caused most likely by 2 issues:
If some of those are omitted - maven could fail with random error messages.
Just hope I've saved somebody from googling around this issue for 6 hours, like I did.

Sometimes it occurs when some installations are not completed correctly, the process is stuck, or a file is still opened. So, when you try to run the installation again and the installation requires deleting, you can see the aforementioned error. In my case, shutting down the python processes and command prompt utilization helped.

I am on a 64 bit system, and I only got this to work after installing both the 32 and 64 bit versions of the redistributable. I did not try the 64 bit version by itself due to the other posters' warnings about using the 32 bit version (and am too lazy to uninstall the 32 bit version now that I have it working), so I don't know if the 32 bit version is needed or not in cases like mine.

if your interested you can also create string extension methods like so:
public static int Search(this string yourString, string yourMarker, int yourInst = 1, bool caseSensitive = true)
{
//returns the placement of a string in another string
int num = 0;
int currentInst = 0;
//if optional argument, case sensitive is false convert string and marker to lowercase
if (!caseSensitive) { yourString = yourString.ToLower(); yourMarker = yourMarker.ToLower(); }
int myReturnValue = -1; //if nothing is found the returned integer is negative 1
while ((num + yourMarker.Length) <= yourString.Length)
{
string testString = yourString.Substring(num, yourMarker.Length);
if (testString == yourMarker)
{
currentInst++;
if (currentInst == yourInst)
{
myReturnValue = num;
break;
}
}
num++;
}
return myReturnValue;
}
public static int Search(this string yourString, char yourMarker, int yourInst = 1, bool caseSensitive = true)
{
//returns the placement of a string in another string
int num = 0;
int currentInst = 0;
var charArray = yourString.ToArray<char>();
int myReturnValue = -1;
if (!caseSensitive)
{
yourString = yourString.ToLower();
yourMarker = Char.ToLower(yourMarker);
}
while (num <= charArray.Length)
{
if (charArray[num] == yourMarker)
{
currentInst++;
if (currentInst == yourInst)
{
myReturnValue = num;
break;
}
}
num++;
}
return myReturnValue;
}

Hash your objects yourself manually, and use the resulting strings as keys for a regular JavaScript dictionary. After all, you are in the best position to know what makes your objects unique. That's what I do.
Example:
var key = function(obj){
// Some unique object-dependent key
return obj.totallyUniqueEmployeeIdKey; // Just an example
};
var dict = {};
dict[key(obj1)] = obj1;
dict[key(obj2)] = obj2;
This way you can control indexing done by JavaScript without heavy lifting of memory allocation, and overflow handling.
Of course, if you truly want the "industrial-grade solution", you can build a class parameterized by the key function, and with all the necessary API of the container, but … we use JavaScript, and trying to be simple and lightweight, so this functional solution is simple and fast.
The key function can be as simple as selecting right attributes of the object, e.g., a key, or a set of keys, which are already unique, a combination of keys, which are unique together, or as complex as using some cryptographic hashes like in DojoX encoding, or DojoX UUID. While the latter solutions may produce unique keys, personally I try to avoid them at all costs, especially, if I know what makes my objects unique.
Update in 2014: Answered back in 2008 this simple solution still requires more explanations. Let me clarify the idea in a Q&A form.
Your solution doesn't have a real hash. Where is it???
JavaScript is a high-level language. Its basic primitive (Object) includes a hash table to keep properties. This hash table is usually written in a low-level language for efficiency. Using a simple object with string keys we use an efficiently implemented hash table without any efforts on our part.
How do you know they use a hash?
There are three major ways to keep a collection of objects addressable by a key:
Obviously JavaScript objects use hash tables in some form to handle general cases.
Do browser vendors really use hash tables???
Really.
Do they handle collisions?
Yes. See above. If you found a collision on unequal strings, please do not hesitate to file a bug with a vendor.
So what is your idea?
If you want to hash an object, find what makes it unique and use it as a key. Do not try to calculate a real hash or emulate hash tables — it is already efficiently handled by the underlying JavaScript object.
Use this key with JavaScript's Object
to leverage its built-in hash table while steering clear of possible clashes with default properties.
Examples to get you started:
I used your suggestion and cached all objects using a user name. But some wise guy is named "toString", which is a built-in property! What should I do now?
Obviously, if it is even remotely possible that the resulting key will exclusively consists of Latin characters, you should do something about it. For example, add any non-Latin Unicode character you like at the beginning or at the end to un-clash with default properties: "#toString", "#MarySmith". If a composite key is used, separate key components using some kind of non-Latin delimiter: "name,city,state".
In general, this is the place where we have to be creative and select the easiest keys with given limitations (uniqueness, potential clashes with default properties).
Note: unique keys do not clash by definition, while potential hash clashes will be handled by the underlying Object
.
Why don't you like industrial solutions?
IMHO, the best code is no code at all: it has no errors, requires no maintenance, easy to understand, and executes instantaneously. All "hash tables in JavaScript" I saw were >100 lines of code, and involved multiple objects. Compare it with: dict[key] = value
.
Another point: is it even possible to beat a performance of a primordial object written in a low-level language, using JavaScript and the very same primordial objects to implement what is already implemented?
I still want to hash my objects without any keys!
We are in luck: ECMAScript 6 (released in June 2015) defines map and set.
Judging by the definition, they can use an object's address as a key, which makes objects instantly distinct without artificial keys. OTOH, two different, yet identical objects, will be mapped as distinct.
Comparison breakdown from MDN:
Objects are similar to Maps in that both let you set keys to values, retrieve those values, delete keys, and detect whether something is stored at a key. Because of this (and because there were no built-in alternatives), Objects have been used as Maps historically; however, there are important differences that make using a Map preferable in certain cases:
- The keys of an Object are Strings and Symbols, whereas they can be any value for a Map, including functions, objects, and any primitive.
- The keys in Map are ordered while keys added to object are not. Thus, when iterating over it, a Map object returns keys in order of insertion.
- You can get the size of a Map easily with the size property, while the number of properties in an Object must be determined manually.
- A Map is an iterable and can thus be directly iterated, whereas iterating over an Object requires obtaining its keys in some fashion and iterating over them.
- An Object has a prototype, so there are default keys in the map that could collide with your keys if you're not careful. As of ES5 this can be bypassed by using map = Object.create(null), but this is seldom done.
- A Map may perform better in scenarios involving frequent addition and removal of key pairs.
This will help you.

Take a look at the Cookie Plugin for jQuery.
Using .NET 4.5 (or .NET 4.0 by adding the Microsoft.Net.Http package from NuGet) there is an easier way to simulate form requests. Here is an example:
private async Task<System.IO.Stream> Upload(string actionUrl, string paramString, Stream paramFileStream, byte [] paramFileBytes)
{
HttpContent stringContent = new StringContent(paramString);
HttpContent fileStreamContent = new StreamContent(paramFileStream);
HttpContent bytesContent = new ByteArrayContent(paramFileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(stringContent, "param1", "param1");
formData.Add(fileStreamContent, "file1", "file1");
formData.Add(bytesContent, "file2", "file2");
var response = await client.PostAsync(actionUrl, formData);
if (!response.IsSuccessStatusCode)
{
return null;
}
return await response.Content.ReadAsStreamAsync();
}
}
With jQuery's validation plugin you could do something like this, assuming that the form is called form and the value to validate is called nrInput
$("form").validate({
errorElement: "div",
errorClass: "error-highlight",
onblur: true,
onsubmit: true,
focusInvalid: true,
rules:{
'nrInput': {
number: true,
required: true
}
});
This also handles decimal values.
This is the way you can compare with others.
# You have to list primes upto n
nums = xrange(2, n)
for i in range(2, 10):
nums = filter(lambda s: s==i or s%i, nums)
print nums
So simple...
If you have simple floats that you control the range of, you can also have an integer in the resources and divide by the number of decimal places you need straight in code.
So something like this
<integer name="strokeWidth">356</integer>
is used with 2 decimal places
this.strokeWidthFromResources = resources_.getInteger(R.integer.strokeWidth);
circleOptions.strokeWidth((float) strokeWidthFromResources/ 100);
and that makes it 3.56f
Not saying this is the most elegant solution but for simple projects, it's convenient.
@Clayton-Graul had what I was looking for, except I needed the CoffeeScript version for a site using AngularJS. Just in case you need that too, here's what you put in the AngularJS controller in question:
# This is how to we do JQuery ready() dom stuff
$ ->
# let's hide those annoying download video options.
# of course anyone who knows how can still download
# the video, but hey... more power to 'em.
$('#my-video').bind 'contextmenu', ->
false
"strange things are afoot at the circle k" (it's true)
You just need to escape the period:
a <- c("NM_020506.1","NM_020519.1","NM_001030297.2","NM_010281.2","NM_011419.3", "NM_053155.2")
gsub("\\..*","",a)
[1] "NM_020506" "NM_020519" "NM_001030297" "NM_010281" "NM_011419" "NM_053155"
You can use:
PyXML:
from xml.dom.ext.reader import Sax2
from xml import xpath
doc = Sax2.FromXmlFile('foo.xml').documentElement
for url in xpath.Evaluate('//@Url', doc):
print url.value
libxml2:
import libxml2
doc = libxml2.parseFile('foo.xml')
for url in doc.xpathEval('//@Url'):
print url.content
Objects don't have a .length
property.
A simple solution if you know you don't have to worry about hasOwnProperty
checks, would be to do this:
Object.keys(data).length;
If you have to support IE 8 or lower, you'll have to use a loop, instead:
var length= 0;
for(var key in data) {
if(data.hasOwnProperty(key)){
length++;
}
}
Here's a really helpful overview of when to base64 encode and when not to by David Calhoun.
Basic answer = gzipped base64 encoded files will be roughly comparable in file size to standard binary (jpg/png). Gzip'd binary files will have a smaller file size.
Takeaway = There's some advantage to encoding and gzipping your UI icons, etc, but unwise to do this for larger images.
Don't forget the option "-o", which lets you download anywhere you want, although you have to create "archives", "lock" and "partial" first (the command prints what's needed).
apt-get install -d -o=dir::cache=/tmp whateveryouwant
According to this source you can obtain your own Context by extending ContextWrapper
public class SomeClass extends ContextWrapper {
public SomeClass(Context base) {
super(base);
}
public void someMethod() {
// notice how I can use "this" for Context
// this works because this class has it's own Context just like an Activity or Service
startActivity(this, SomeRealActivity.class);
//would require context too
File cacheDir = getCacheDir();
}
}
Proxying implementation of Context that simply delegates all of its calls to another Context. Can be subclassed to modify behavior without changing the original Context.
In my case the solution was easy. You don't need to declare anything in your web.xml
.
Because your project is a web application, the config file should be on WEB-INF/classes
after deployment.
I advise you to create a Java resource folder (src/main/resources
) to do that (best pratice). Another approach is to put the config file in your src/main/java
.
Beware with the configuration file name. If you are using XML, the file name is log4j.xml
, otherwise log4j.properties
.
$('document').ready(function () {
$("#imgload").change(function () {
if (this.files && this.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#imgshow').attr('src', e.target.result);
}
reader.readAsDataURL(this.files[0]);
}
});
});

That works for me in jQuery.
in rare cases when you can't use strncat
, strcat
or strcpy
. And you don't have access to <string.h>
so you can't use strlen
. Also you maybe don't even know the size of the char arrays and you still want to concatenate because you got only pointers. Well, you can do old school malloc and count characters yourself like..
char *combineStrings(char* inputA, char* inputB) {
size_t len = 0, lenB = 0;
while(inputA[len] != '\0') len++;
while(inputB[lenB] != '\0') lenB++;
char* output = malloc(len+lenB);
sprintf((char*)output,"%s%s",inputA,inputB);
return output;
}
It just needs #include <stdio.h>
which you will have most likely included already
Also,
If you're running your page from Visual Studio and have installed the bootstrap package you need to make sure of two things
As per the title of the post I just needed to get all values from a specific column. Here is the code I used to achieve that.
public static IEnumerable<T> ColumnValues<T>(this DataColumn self)
{
return self.Table.Select().Select(dr => (T)Convert.ChangeType(dr[self], typeof(T)));
}
The short answer is: never!
The only case I could imagine is, that you run this on a webkit browser like Chrome or Safari and your return value in responseText
, contains a string value.
In that constelation, the value cannot be displayed (it would get blank)
Example: http://jsfiddle.net/BmhNL/2/
My point here is, that I expect a wrong/double encoded string value. Webkit browsers are more strict on the type
= number
. If there is "only" a white-space issue, you can try to implicitly call the Number()
constructor, like
document.getElementById("points").value = +request.responseText;
There is no string
type in C
. You have to use char arrays.
By the way your code will not work ,because the size of the array should allow for the whole array to fit in plus one additional zero terminating character.
Just before executing the query: alter session set NLS_DATE_FORMAT = "DD.MM.YYYY HH24:MI:SS"; or whichever format you are giving the information to the date function. This should fix the ORA error
Your update syntax is incorrect. Please check Update Syntax for the correct syntax.

The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.
The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.
In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.
The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.
Here is an example of a JavaDoc comment from Oracle:
/**
* Returns an Image object that can then be painted on the screen.
* The url argument must specify an absolute {@link URL}. The name
* argument is a specifier that is relative to the url argument.
* <p>
* This method always returns immediately, whether or not the
* image exists. When this applet attempts to draw the image on
* the screen, the data will be loaded. The graphics primitives
* that draw the image will incrementally paint on the screen.
*
* @param url an absolute URL giving the base location of the image
* @param name the location of the image, relative to the url argument
* @return the image at the specified URL
* @see Image
*/
public Image getImage(URL url, String name) {
try {
return getImage(new URL(url, name));
} catch (MalformedURLException e) {
return null;
}
}
The basic format can be auto generated in either of the following ways:
If you have simple dropdown like:
<select name="status" id="status">
<option value="1">Active</option>
<option value="0">Inactive</option>
</select>
Then you can use this code for getting value:
$(function(){
$("#status").change(function(){
var status = this.value;
alert(status);
if(status=="1")
$("#icon_class, #background_class").hide();// hide multiple sections
});
});
make sure to open the command line with "run as administrator" rights in the right click before typing the entire mongod things
<?php
session_start();
if (time()<$_SESSION['time']+10){
$_SESSION['time'] = time();
echo "welcome old user";
}
else{
session_destroy();
session_start();
$_SESSION['time'] = time();
echo "welcome new user";
}
?>
To get reference to UIViewController having UIView, you could make extension of UIResponder (which is super class for UIView and UIViewController), which allows to go up through the responder chain and thus reaching UIViewController (otherwise returning nil).
extension UIResponder {
func getParentViewController() -> UIViewController? {
if self.nextResponder() is UIViewController {
return self.nextResponder() as? UIViewController
} else {
if self.nextResponder() != nil {
return (self.nextResponder()!).getParentViewController()
}
else {return nil}
}
}
}
//Swift 3
extension UIResponder {
func getParentViewController() -> UIViewController? {
if self.next is UIViewController {
return self.next as? UIViewController
} else {
if self.next != nil {
return (self.next!).getParentViewController()
}
else {return nil}
}
}
}
let vc = UIViewController()
let view = UIView()
vc.view.addSubview(view)
view.getParentViewController() //provide reference to vc
Google thrives on scraping websites of the world...so if it was "so illegal" then even Google won't survive ..of course other answers mention ways of mitigating IP blocks by Google. One more way to explore avoiding captcha could be scraping at random times (dint try) ..Moreover, I have a feeling, that if we provide novelty or some significant processing of data then it sounds fine at least to me...if we are simply copying a website.. or hampering its business/brand in some way...then it is bad and should be avoided..on top of it all...if you are a startup then no one will fight you as there is no benefit.. but if your entire premise is on scraping even when you are funded then you should think of more sophisticated ways...alternative APIs..eventually..Also Google keeps releasing (or depricating) fields for its API so what you want to scrap now may be in roadmap of new Google API releases..
7 years later, allow me to give a one-liner solution by building on a previous answer. You could do the followwing:
numbers = [1, 2, 3]
to Add [3, 4, 5]
into numbers
without repeating 3
, do the following:
numbers = list(set(numbers + [3, 4, 5]))
This results in 4
and 5
being added to numbers
as in [1, 2, 3, 4, 5]
Explanation:
Now let me explain what happens, starting from the inside of the set()
instruction, we took numbers
and added 3
, 4
, and 5
to it which makes numbers
look like [1, 2, 3, 3, 4, 5]
.
Then, we took that ([1, 2, 3, 3, 4, 5]
) and transformed it into a set which gets rid of duplicates, resulting in the following {1, 2, 3, 4, 5}
. Now since we wanted a list and not a set, we used the function list()
to make that set ({1, 2, 3, 4, 5}
) into a list, resulting in [1, 2, 3, 4, 5]
which we assigned to the variable numbers
This, I believe, will work for all types of data in a list, and objects as well if done correctly.
DataTable dataTable = new DataTable();
dataTable = OldDataTable.Tables[0].Clone();
foreach(DataRow dr in RowData.Tables[0].Rows)
{
DataRow AddNewRow = dataTable.AddNewRow();
AddNewRow.ItemArray = dr.ItemArray;
dataTable.Rows.Add(AddNewRow);
}
If you want a NULL
return value you need to use pointers instead of references.
References can't themselves be NULL
.
(Note to the future comment posters: Yes you can have the address of a reference be NULL if you really really try to).
See my answer here for a list of differences between references and pointers.
Yes, datepicker supports max date property.
$("#datepickeraddcustomer").datepicker({
dateFormat: "yy-mm-dd",
maxDate: new Date()
});
There are lots of data types you can mention while creating model, some examples are:
:primary_key, :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time, :date, :binary, :boolean, :references
syntax:
field_type:data_type
My answer is a mod of some prior answers from @JoeMills and @user.
Get a cURL
command to log into server:
Modify cURL command to be able to save session cookie after login
-H 'Cookie: <somestuff>'
curl
at beginning -c login_cookie.txt
'login_cookie.txt'
in the same folderCall a new web page using this new cookie that requires you to be logged in
curl -b login_cookie.txt <url_that_requires_log_in>
I have tried this on Ubuntu 20.04 and it works like a charm.
I find this works easier. readonly the input field, then style it so the end user knows it's read only. inputs placed here (from AJAX for example) can still submit, without extra code.
<input readonly style="color: Grey; opacity: 1; ">
The easiest way to do this would be to use a filter.
You can either filter for any cells in column A that don't have a "-" and copy / paste, or (my more preferred method) filter for all cells that do have a "-" and then select all and delete - Once you remove the filter, you're left with what you need.
Hope this helps.
Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:
File Thread Safe VC Bulid
php_sqlsrv_53_nts_vc6.dll No VC6
php_sqlsrv_53_nts_vc9.dll No VC9
php_sqlsrv_53_ts_vc6.dll Yes VC6
php_sqlsrv_53_ts_vc9.dll Yes VC9
You can see the Thread Safety status in phpinfo().
Add the correct file to your ext directory and the following line to your php.ini:
extension=php_sqlsrv_53_*_vc*.dll
Use the filename of the file you used.
As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*
Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.
In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2
To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.
Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.
You can use
Uri.EscapeUriString (see http://msdn.microsoft.com/en-us/library/system.uri.escapeuristring.aspx)
You can also do it with print
instead of write
:
with open('test.txt', 'a') as f:
print('appended text', file=f)
If test.txt doesn't exist, it will be created...

By default, no you can't know if a variable (or pointer) has or hasn't been initialized. However, since everyone else is telling you the "easy" or "normal" approach, I'll give you something else to think about. Here's how you could keep track of something like that (no, I personally would never do this, but perhaps you have different needs than me).
class MyVeryCoolInteger
{
public:
MyVeryCoolInteger() : m_initialized(false) {}
MyVeryCoolInteger& operator=(const int integer)
{
m_initialized = true;
m_int = integer;
return *this;
}
int value()
{
return m_int;
}
bool isInitialized()
{
return m_initialized;
}
private:
int m_int;
bool m_initialized;
};
If you run pub build --mode=debug
the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug
is used.
Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline
Try using white-space: pre-line;
. It creates a line-break wherever a line-break appears in the code, but ignores the extra whitespace (tabs and spaces etc.).
First, write your words on separate lines in your code:
<div>Short
Word</div>
Then apply the style to the element containing the words.
div { white-space: pre-line; }
Be careful though, every line break in the code inside the element will create a line break. So writing the following will result in an extra line break before the first word and after the last word:
<div>
Short
Word
</div>
There's a great article on CSS Tricks explaining the other white-space attributes.
Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax()
method. Or if you wanted to do it using plain javascript, here's a tutorial.
Yes, the Jackson manual parser design is quite different from other libraries. In particular, you will notice that JsonNode
has most of the functions that you would typically associate with array nodes from other API's. As such, you do not need to cast to an ArrayNode
to use. Here's an example:
JSON:
{
"objects" : ["One", "Two", "Three"]
}
Code:
final String json = "{\"objects\" : [\"One\", \"Two\", \"Three\"]}";
final JsonNode arrNode = new ObjectMapper().readTree(json).get("objects");
if (arrNode.isArray()) {
for (final JsonNode objNode : arrNode) {
System.out.println(objNode);
}
}
Output:
"One"
"Two"
"Three"
Note the use of isArray
to verify that the node is actually an array before iterating. The check is not necessary if you are absolutely confident in your datas structure, but its available should you need it (and this is no different from most other JSON libraries).
n = Math.floor(x);
remainder = x % 1;
You will get useful information from here.

Unfortunately, the above solution did not work for Jython Fiji plugin. I had to use getProperty to construct the relative path dynamically.
Here's what worked for me:
import java.lang.System.getProperty;
import javax.swing.JFrame;
import javax.swing.ImageIcon;
frame = JFrame("Test")
icon = ImageIcon(getProperty('fiji.dir') + '/path/relative2Fiji/icon.png')
frame.setIconImage(icon.getImage());
frame.setVisible(True)
Just set this to v21/styles.xml file
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/colorPrimaryDark</item>
and be sure
<item name="android:windowTranslucentStatus">false</item>
Add
t1.Join(); // Wait until thread t1 finishes
after you start it, but that won't accomplish much as it's essentialy the same result as running on the main thread!
I can highly recommended reading Joe Albahari's Threading in C# free e-book, if you want to gain an understanding of threading in .NET.
You could just declare a DBMS_SQL.VARCHAR2_TABLE to hold an in-memory variable length array indexed by a BINARY_INTEGER:
DECLARE
name_array dbms_sql.varchar2_table;
BEGIN
name_array(1) := 'Tim';
name_array(2) := 'Daisy';
name_array(3) := 'Mike';
name_array(4) := 'Marsha';
--
FOR i IN name_array.FIRST .. name_array.LAST
LOOP
-- Do something
END LOOP;
END;
You could use an associative array (used to be called PL/SQL tables) as they are an in-memory array.
DECLARE
TYPE employee_arraytype IS TABLE OF employee%ROWTYPE
INDEX BY PLS_INTEGER;
employee_array employee_arraytype;
BEGIN
SELECT *
BULK COLLECT INTO employee_array
FROM employee
WHERE department = 10;
--
FOR i IN employee_array.FIRST .. employee_array.LAST
LOOP
-- Do something
END LOOP;
END;
The associative array can hold any make up of record types.
Hope it helps, Ollie.
If you are allowed to change the code of the document inside your iframe
and that content is visible only using its parent window, simply add the following CSS in your iframe
:
body {
overflow:hidden;
}
Here a very simple example:
This solution allow you to:
Keep you HTML5 valid as it does not need scrolling="no"
attribute on the iframe
(this attribute in HTML5 has been deprecated).
Works on the majority of browsers using CSS overflow:hidden
No JS or jQuery necessary.
Notes:
To disallow scroll-bars horizontally, use this CSS instead:
overflow-x: hidden;
It's been a while but for future reference: the method shouldComponentUpdate() can be used.
An update can be caused by changes to props or state. These methods are called in the following order when a component is being re-rendered:
static getDerivedStateFromProps()
shouldComponentUpdate()
render()
getSnapshotBeforeUpdate()
componentDidUpdate()
just to add the full command:
adb shell ls -R | grep filename
this is actually a pretty fast lookup on Android
For the Googlers: building on Max's answer, to solve the padding issue that many have noticed I simply increased the height of the label and used that height as the separator instead of actual padding. This idea could be expanded for any scenario with containing views.
Here's a simple example:
In this case, I map the height of the Author label to an appropriate IBOutlet
:
@property (retain, nonatomic) IBOutlet NSLayoutConstraint* authorLabelHeight;
and when I set the height of the constraint to 0.0f
, we preserve the "padding", because the Play button's height allows for it.
The best way to do this is just install the .EXE file into the windows/system32 folder. that way you can run it from any location. This is the same place where .exe's like ping can be found
Use the set
method to replace the old value with a new one.
list.set( 2, "New" );
Store your zipcodes as CHAR(5) instead of a numeric type, or have your application pad it with zeroes when you load it from the DB. A way to do it with PHP using sprintf()
:
echo sprintf("%05d", 205); // prints 00205
echo sprintf("%05d", 1492); // prints 01492
Or you could have MySQL pad it for you with LPAD()
:
SELECT LPAD(zip, 5, '0') as zipcode FROM table;
Here's a way to update and pad all rows:
ALTER TABLE `table` CHANGE `zip` `zip` CHAR(5); #changes type
UPDATE table SET `zip`=LPAD(`zip`, 5, '0'); #pads everything
As of this posting it looks like TradeKing is working on an API. Not sure what the future of it is though.
If you have Perl 5.14 or greater, you can use the /r
option with the substitution operator to perform non-destructive substitution:
print "bla: ", $myvar =~ s/a/b/r, "\n";
In earlier versions you can achieve the same using a do()
block with a temporary lexical variable, e.g.:
print "bla: ", do { (my $tmp = $myvar) =~ s/a/b/; $tmp }, "\n";
How about using unique()
itself?
df <- data.frame(yad = c("BARBIE", "BARBIE", "BAKUGAN", "BAKUGAN"),
per = c("AYLIK", "AYLIK", "2 AYLIK", "2 AYLIK"),
hmm = 1:4)

# yad per hmm
# 1 BARBIE AYLIK 1
# 2 BARBIE AYLIK 2
# 3 BAKUGAN 2 AYLIK 3
# 4 BAKUGAN 2 AYLIK 4
unique(df[c("yad", "per")])
# yad per

You can only use one color but as many images as you want, here is the format:
background: [ <bg-layer> , ]* <final-bg-layer>
<bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2}
<final-bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2} || <background-color>
or
background: url(image1.png) center bottom no-repeat, url(image2.png) left top no-repeat;
If you need more colors, make an image of a solid color and use it. I know it’s not what you want to hear, but I hope it helps.
The format is from http://www.css3.info/preview/multiple-backgrounds/
As of January 2nd, 2021, Google posted these two keys for testing in this article.
I'd like to run automated tests with reCAPTCHA. What should I do? For reCAPTCHA v3, create a separate key for testing environments. Scores may not be accurate as reCAPTCHA v3 relies on seeing real traffic.
For reCAPTCHA v2, use the following test keys. You will always get No CAPTCHA and all verification requests will pass.
Site key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI
Secret key: 6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWe
The reCAPTCHA widget will show a warning message to ensure it's not used for production traffic.
The generated emails went into spam the first time I used the keys.
Actualy you can do almost everything with dropdown field, and it will looks the same on every browser, take a look at code example

Close()
in code?You cannot rely on close reason of the form closing event args, because if the user click X button on title bar or close the form using Alt + F4 or use system menu to close the form or the form get closed by calling Close()
method, all all above cases, the close reason will be Closed by User which is not desired result.
To distinguish if the form closed by X button or by Close
method, you can use either of the following options:
WM_SYSCOMMAND
and check for SC_CLOSE
and set a flag.StackTrace
to see if any of the frames contain Close
method call.Example 1 - Handle WM_SYSCOMMAND
public bool ClosedByXButtonOrAltF4 {get; private set;}
private const int SC_CLOSE = 0xF060;
private const int WM_SYSCOMMAND = 0x0112;
protected override void WndProc(ref Message msg)
{
if (msg.Msg == WM_SYSCOMMAND && msg.WParam.ToInt32() == SC_CLOSE)
ClosedByXButtonOrAltF4 = true;
base.WndProc(ref msg);
}
protected override void OnShown(EventArgs e)
{
ClosedByXButtonOrAltF4 = false;
}
protected override void OnFormClosing(FormClosingEventArgs e)
{
if (ClosedByXButtonOrAltF4)
MessageBox.Show("Closed by X or Alt+F4");
else
MessageBox.Show("Closed by calling Close()");
}
Example 2 - Checking StackTrace
protected override void OnFormClosing(FormClosingEventArgs e)
{
if (new StackTrace().GetFrames().Any(x => x.GetMethod().Name == "Close"))
MessageBox.Show("Closed by calling Close()");
else
MessageBox.Show("Closed by X or Alt+F4");
}
You already have what you need, with a minor syntax change:
<a href="www.mysite.com" onclick="return theFunction();">Item</a>
<script type="text/javascript">
function theFunction () {
// return true or false, depending on whether you want to allow the `href` property to follow through or not
}
</script>
The default behavior of the <a>
tag's onclick
and href
properties is to execute the onclick
, then follow the href
as long as the onclick
doesn't return false
, canceling the event (or the event hasn't been prevented)
Add this class in .css class
.scrol {

overflow-y:scroll;
overflow-x:hidden;
}
and use the class in div. like here.
<div> <p class = "scrol" id = "title">-</p></div>

Updating a pull request in GitHub is as easy as committing the wanted changes into existing branch (that was used with pull request), but often it is also wanted to squash the changes into single commit:
git checkout yourbranch
git rebase -i origin/master
# Edit command names accordingly
pick 1fc6c95 My pull request
squash 6b2481b Hack hack - will be discarded
squash dd1475d Also discarded
git push -f origin yourbranch
...and now the pull request contains only one commit.

So I wanted to do something slightly different: a border on the bottom ONLY, to simulate a ListView divider. I modified Piet Delport's answer and got this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape
android:shape="rectangle">
<solid android:color="@color/background_trans_light" />
</shape>
</item>
<!-- this mess is what we have to do to get a bottom border only. -->
<item android:top="-2dp"
android:left="-2dp"
android:right="-2dp"
android:bottom="1px">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="@color/background_trans_mid" />
<solid android:color="@null" />
</shape>
</item>
</layer-list>
Note using px instead of dp to get exactly 1 pixel divider (some phone DPIs will make a 1dp line disappear).

You can use JSON-RPC with "less verb" (no method) and preserve the minimal standardization necessary for sendo id, parameters, error codes and warning messages. The JSON-RPC standard not say "you can't be REST", only say how to pack basic information.
"REST JSON-RPC" exists! is REST with "best practices", for minimal information packing, with simple and solid contracts.
(from this answer and didactic context)
When dealing with REST, it generally helps to start by thinking in terms of resources. In this case, the resource is not just "bank account" but it is a transaction of that bank account... But JSON-RPC not obligates the "method" parameter, all are encoded by "path" of the endpoint.
REST Deposit with POST /Bank/Account/John/Transaction
with JSON request {"jsonrpc": "2.0", "id": 12, "params": {"currency":"USD","amount":10}}
.
The JSON response can be something as {"jsonrpc": "2.0", "result": "sucess", "id": 12}
REST Withdraw with POST /Bank/Account/John/Transaction
... similar.
... GET /Bank/Account/John/Transaction/12345@13
... This could return a JSON record of that exact transaction (e.g. your users generally want a record of debits and credits on their account). Something as {"jsonrpc": "2.0", "result": {"debits":[...],"credits":[...]}, "id": 13}
. The convention about (REST) GET request can include encode of id by "@id", so not need to send any JSON, but still using JSON-RPC in the response pack.
This solution is based from this website: http://social.msdn.microsoft.com/Forums/en-US/bd0ee306-7bb5-4ce4-8341-edd9475f84ad/excel-2007-use-vba-to-download-save-csv-from-url

In Xcode 7 you can have multiple storyBoards. It will be better if you can keep the Login flow in a separate storyboard.
This can be done using SELECT VIEWCONTROLLER > Editor > Refactor to Storyboard
And here is the Swift version for setting a view as the RootViewContoller-
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window!.rootViewController = newRootViewController
let rootViewController: UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("LoginViewController")
You can also do it this way.
Create the following named ranges:
nList = the list of original values
nRow = ROW(nList)-ROW(OFFSET(nList,0,0,1,1))+1
nUnique = IF(COUNTIF(OFFSET(nList,nRow,0),nList)=0,COUNTIF(nList, "<"&nList),"")
With these 3 named ranges you can generate the ordered list of unique values with the formula below. It will be sorted in ascending order.
IFERROR(INDEX(nList,MATCH(SMALL(nUnique,ROW()-?),nUnique,0)),"")
You will need to substitute the row number of the cell just above the first element of your unique ordered list for the '?' character.
eg. If your unique ordered list begins in cell B5 then the formula will be:
IFERROR(INDEX(nList,MATCH(SMALL(nUnique,ROW()-4),nUnique,0)),"")

You really should implement prefersStatusBarHidden on your view controller(s):
Swift 3 and later
override var prefersStatusBarHidden: Bool {
return true
}
If you look at the output you receive from print()
and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b
):
b'{\n "note":"This file .....
If you fetch the URL using a tool such as curl -v
, you will see that the content type is
Content-Type: application/json; charset=utf-8
So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.
Change the last line of code to this:
info = json.loads(js.decode("utf-8"))

I would go with option A:
String.Join(String.Empty, los.ToArray());
My reasoning is because the Join method was written for that purpose. In fact if you look at Reflector, you'll see that unsafe code was used to really optimize it. The other two also WORK, but I think the Join function was written for this purpose, and I would guess, the most efficient. I could be wrong though...
As per @Nuri YILMAZ without .ToArray()
, but this is .NET 4+:
String.Join(String.Empty, los);

There are many answers to this question, all of which I feel are not satisfactory (some more than others), of the many extensions - code folding, folding by headings etc etc. None do what I want in simple and effective way. I am literally amazed that a solution has not been implemented (as it has for Jupyter Lab).
In fact, I was so dissatisfied that I have developed a very simple notebook extension that can expand/collapse the code in a notebook cell, while keeping it executable.
The GitHub repository: https://github.com/BenedictWilkinsAI/cellfolding
Below is a small demo of what the extension does:
Simply double clicking left of the code cell will collapse it to a single line:
Double clicking again will expand the cell.
The extension can be installed easily with pip:
pip install nbextension-cellfolding
jupyter nbextension install --py cellfolding --user
jupyter nbextension enable --py cellfolding --user
and is also compatible with nbextension configurator. I hope that people will find this useful!
I had this problem on android Studio because in my Debug build i've added version name suffix -DEBUG and the - was the problem.
Another option, without dropping or filtering in a loop:
import numpy as np
import pandas as pd
# Create a dataframe with columns A,B,C and D
df = pd.DataFrame(np.random.randn(100, 4), columns=list('ABCD'))
# include the columns you want
df[df.columns[df.columns.isin(['A', 'B'])]]
# or more simply include columns:
df[['A', 'B']]
# exclude columns you don't want
df[df.columns[~df.columns.isin(['C','D'])]]
# or even simpler since 0.24
# with the caveat that it reorders columns alphabetically
df[df.columns.difference(['C', 'D'])]
Here is an example. Imagine that you are going to put the files and directory names (under the current folder) to an array and count its items. The script would be like;
my_array=( `ls` )
my_array_length=${#my_array[@]}
echo $my_array_length
Or, you can iterate over this array by adding the following script:
for element in "${my_array[@]}"
do
echo "${element}"
done
Please note that this is the core concept and the input is considered to be sanitized before, i.e. removing extra characters, handling empty Strings, and etc. (which is out of the topic of this thread).

It helped me.
You have to catch the error just as you're already doing for your save()
call and since you're handling multiple errors here, you can try
multiple calls sequentially in a single do-catch block, like so:
func deleteAccountDetail() {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
do {
let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
} catch {
print(error)
}
}
Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws
then try
to call the method. For example:
func deleteAccountDetail() throws {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
}
Not a technical answer, but I have built an application which allows for wildcard search: https://bucketsearch.net/
It will asynchronously index your bucket and then allow you to search the results.
It's free to use (donationware).
This doesn't use sed, but using >> will append to a file. For example:
echo 'one, two, three' >> testfile.csv
Edit: To prepend to a file, try something like this:
echo "text"|cat - yourfile > /tmp/out && mv /tmp/out yourfile
I found this through a quick Google search.
Try this, just an example:
u.UserTypeOptions = new SelectList(new[]
{
new { ID="1", Name="name1" },
new { ID="2", Name="name2" },
new { ID="3", Name="name3" },
}, "ID", "Name", 1);
Or
u.UserTypeOptions = new SelectList(new List<SelectListItem>
{
new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
},"Value","Text");
I faced this problem while trying to extend an existing class from GitHub. I'm gonna try to explain myself, first writing the class as I though it should be, and then the class as it is now.
What I though
namespace mycompany\CutreApi;
use mycompany\CutreApi\ClassOfVendor;
class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
public function whatever(): ClassOfVendor
{
return new ClassOfVendor();
}
}
What I've finally done
namespace mycompany\CutreApi;
use \vendor\AwesomeApi\ClassOfVendor;
class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
public function whatever(): ClassOfVendor
{
return new \mycompany\CutreApi\ClassOfVendor();
}
}
So seems that this errror raises also when you're using a method that return a namespaced class, and you try to return the same class but with other namespace. Fortunately I have found this solution, but I do not fully understand the benefit of this feature in php 7.2, for me it is normal to rewrite existing class methods as you need them, including the redefinition of input parameters and / or even behavior of the method.
One downside of the previous aproach, is that IDE's could not recognise the new methods implemented in \mycompany\CutreApi\ClassOfVendor(). So, for now, I will go with this implementation.
Currently done
namespace mycompany\CutreApi;
use mycompany\CutreApi\ClassOfVendor;
class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
public function getWhatever(): ClassOfVendor
{
return new ClassOfVendor();
}
}
So, instead of trying to use "whatever" method, I wrote a new one called "getWhatever". In fact both of them are doing the same, just returning a class, but with diferents namespaces as I've described before.
Hope this can help someone.
The most simplest solution I have seen to supply a short execution to the UI thread is via the post() method of a view. This is needed since UI methods are not re-entrant. The method for this is:
package android.view;
public class View;
public boolean post(Runnable action);
The post() method corresponds to the SwingUtilities.invokeLater(). Unfortunately I didn't find something simple that corresponds to the SwingUtilities.invokeAndWait(), but one can build the later based on the former with a monitor and a flag.
So what you save by this is creating a handler. You simply need to find your view and then post on it. You can find your view via findViewById() if you tend to work with id-ed resources. The resulting code is very simple:
/* inside your non-UI thread */
view.post(new Runnable() {
public void run() {
/* the desired UI update */
}
});
}
Note: Compared to SwingUtilities.invokeLater() the method View.post() does return a boolean, indicating whether the view has an associated event queue. Since I used the invokeLater() resp. post() anyway only for fire and forget, I did not check the result value. Basically you should call post() only after onAttachedToWindow() has been called on the view.
Best Regards
You need to rearrange your curly brackets. Your first statement is complete, so R interprets it as such and produces syntax errors on the other lines. Your code should look like:
if (dsnt<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else if (dst<0.05) {
wilcox.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
} else {
t.test(distance[result=='nt'],distance[result=='t'],alternative=c("two.sided"),paired=TRUE)
}
To put it more simply, if you have:
if(condition == TRUE) x <- TRUE
else x <- FALSE
Then R reads the first line and because it is complete, runs that in its entirety. When it gets to the next line, it goes "Else? Else what?" because it is a completely new statement. To have R interpret the else as part of the preceding if statement, you must have curly brackets to tell R that you aren't yet finished:
if(condition == TRUE) {x <- TRUE
} else {x <- FALSE}
You can loop through the select_obj.options. There's a #text method in each of the option object, which you can use to compare to what you want and set the selectedIndex of the select_obj.
I got the same error-message executed the
:PluginUpdate command from the vim editors command-line
"Please commit your changes or stash them before you merge"
1. just physically removed the folder contained the plugins form the
rm -rf ~/.vim/bundle/plugin-folder/
2. and reinstalled it form the vim commandline,
:PluginInstall!
because my ~/.vimrc contained the instructions to build the plugin to that destination:
this created the proper folder,
and got new package into that folder ~./.vim/bundle/reinstalled-plugins-folder
The "!" signs (due to the unsuccessful PluginUpdate command)
were changed
to "+" signs, and after that worked the PluginUpdate command to.
You're very close. What you need to remember is when you're calling a method from another class you need to tell the compiler where to find that method.
So, instead of simply calling addWord("someWord")
, you will need to initialise an instance of the WordList class (e.g. WordList list = new WordList();
), and then call the method using that (i.e. list.addWord("someWord");
.
However, your code at the moment will still throw an error there, because that would be trying to call a non-static method from a static one. So, you could either make addWord()
static, or change the methods in the Words class so that they're not static.
My bad with the above paragraph - however you might want to reconsider ProcessInput()
being a static method - does it really need to be?

Both setInterval and setTimeout return a timer id that you can use to cancel the execution, that is, before the timeouts are triggered. To cancel you call either clearInterval or clearTimeout like this:
var timeoutId = setTimeout(someFunction, 1000);
clearTimeout(timeoutId);
var intervalId = setInterval(someFunction, 1000),
clearInterval(intervalId);
Also, the timeouts are automatically cancelled when you leave the page or close the browser window.
$('#txtInput').attr('maxLength', 100);
I used the action delegate like this in a project once:
private static Dictionary<Type, Action<Control>> controldefaults = new Dictionary<Type, Action<Control>>() {
{typeof(TextBox), c => ((TextBox)c).Clear()},
{typeof(CheckBox), c => ((CheckBox)c).Checked = false},
{typeof(ListBox), c => ((ListBox)c).Items.Clear()},
{typeof(RadioButton), c => ((RadioButton)c).Checked = false},
{typeof(GroupBox), c => ((GroupBox)c).Controls.ClearControls()},
{typeof(Panel), c => ((Panel)c).Controls.ClearControls()}
};
which all it does is store a action(method call) against a type of control so that you can clear all the controls on a form back to there defaults.
This will return the first 200 characters of words:
preg_replace('/\s+?(\S+)?$/', '', substr($string, 0, 201));
In most situations, git fetch
should do what you want, which is 'get anything new from the remote repository and put it in your local copy without merging to your local branches'. git fetch --tags
does exactly that, except that it doesn't get anything except new tags.
In that sense, git fetch --tags
is in no way a superset of git fetch
. It is in fact exactly the opposite.
git pull
, of course, is nothing but a wrapper for a git fetch <thisrefspec>; git merge
. It's recommended that you get used to doing manual git fetch
ing and git merge
ing before you make the jump to git pull
simply because it helps you understand what git pull
is doing in the first place.
