If you happen to have a shell opened inside Emacs  you can also do         emacs   May save a few key strokes

Others already answered your question as stated  but I find that I usually want to execute the lines that I just wrote  for that  CtrlAltx in the lisp works just fine

I m currently on Ubuntu 15 04  I like to define a key for this   M-insert  translates to alt-insert on my keyboard  Put this in your  emacs file        global-set-key  M-insert    lambda    interactive   load-file     emacs

You can usually just re-evaluate the changed region   Mark the region of    emacs that you ve changed  and then use M-x eval-region RET   This is often safer than re-evaluating the entire file since it s easy to write a  emacs file that doesn t work quite right after being loaded twice

You can use the command load-file  M-x load-file  then press return twice to accept the default filename  which is the current file being edited    You can also just move the point to the end of any sexp and press C-xC-e to execute just that sexp  Usually it s not necessary to reload the whole file if you re just changing a line or two

solution  M-   load user-init-file     notes   you type it in Eval  prompt  including the parentheses  user-init-file is a variable holding the     emacs value  pointing to the configuration file path  by default  load  is shorter  older  and non-interactive version of  load-file   it is not an emacs command  to be typed in M-x  but a mere elisp function     conclusion  M-    M-x

I suggest that you don t do this  initially   Instead  start a new emacs session and test whatever changes you made to see if they work correctly   The reason to do it this way is to avoid leaving you in a state where you have an inoperable  emacs file  which fails to load or fails to load cleanly   If you do all of your editing in the original session  and all of your testing in a new session  you ll always have something reliable to comment out offending code   When you are finally happy with your changes  then go ahead and use one of the other answers to re-load   My personal preference is to eval just the section you ve added changed  and to do that just highlight the region of added changed code and call M-x eval-region   Doing that minimizes the code that s evaluated  minimizing any unintentional side-effects  as luapyad points out

Here is a quick and easy way to quick test your config  You can also use C-x C-e at the end of specific lisp to execute certain function individually      C-x C-e runs the command eval-last-sexp  found in global-map   which   is an interactive compiled Lisp function       It is bound to C-x C-e        eval-last-sexp EVAL-LAST-SEXP-ARG-INTERNAL       Evaluate sexp before point  print value in the echo area    Interactively  with prefix argument  print output into current buffer       Normally  this function truncates long output according to the value   of the variables    eval-expression-print-length    and      eval-expression-print-level      With a prefix argument of zero    however  there is no such truncation   Such a prefix argument also   causes integers to be printed in several additional formats  octal    hexadecimal  and character        If    eval-expression-debug-on-error    is non-nil  which is the default    this command arranges for all errors to enter the debugger

Although M-x eval-buffer will work you may run into problems with toggles and other similar things  A better approach might be to  mark  or highlight whats new in your  emacs  or even scratch buffer if your just messing around  and then M-x eval-region  Hope this helps

Very strange that the very convenient   M-x eval-buffer  is not mentioned here   It immediately evaluates all code in the buffer  its the quickest method  if your  emacs is idempotent

User · Answer

You can set key-binding for emacs like this     reload emacs configuration  defun reload-init-file       interactive     load-file     emacs      global-set-key  kbd  C-c r    reload-init-file     Hope this will help
