** What is this? This is a simple package to restart Emacs for within Emacs. Inspired by [[http://emacs.stackexchange.com/questions/5428/restart-emacs-from-within-emacs][this]] stackoverflow question.
** Installation
*** ELPA
restart-emacs is available on [[http://melpa.org/#/restart-emacs][MELPA]] and [[http://stable.melpa.org/#/restart-emacs][MELPA Stable]]. Please follow the instructions on
MELPA [[http://melpa.org/#/getting-started][website]] to enable it, if you haven't already.
You can then install ~restart-emacs~ from the [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Package-Menu.html][package menu]]. Alternatively install it by doing the following
Refresh the package index
#+BEGIN_QUOTE
M-x package-refresh-contents RET
#+END_QUOTE
And then install it by doing
#+BEGIN_QUOTE
M-x package-install RET restart-emacs
#+END_QUOTE
*** El-get
restart-emacs can also be installed using el-get. Assuming you have latest version of el-get installing it by doing something similar to
#+BEGIN_QUOTE
M-x el-get-install RET restart-emacs
#+END_QUOTE
** Usage
It offers a command restart-emacs which kills current Emacs session
and starts a new session.
Additional arguments to be passed to the new instance can be specified using prefix arguments
- with a single
universal-argument(=C-u=) Emacs is restarted with--debug-initflag - with two
universal-argument(=C-u= =C-u=) Emacs is restarted with-Qflag - with three
universal-argument(=C-u= =C-u= =C-u=) the user is prompted for the arguments
restart-emacs can restore frames on restart, right this is experimental and
disabled by default to enable it set restart-emacs-restore-frames to t.
There is also a second command restart-emacs-start-new-emacs which starts a
new session of Emacs without killing the current one. It takes the same arguments
as restart-emacs.
** Compatibility
*** Restarting GUI Emacs
Restarting graphical Emacs should work on any UNIXy system with sh and on
Windows.
*** Restarting Emacs running in a terminal
This requires that the shell from which Emacs was launched supports job
control. This has been tested to work on sh, bash, zsh, fish, csh
and tcsh, however this does not work on Windows.
*** Restarting Emacs daemons
The latest version of restart-emacs can now restart Emacs daemons. The the
frames are restored once the daemon restarts using desktop-mode. However
since desktop-mode learned to restore frames only Emacs version 24.4
onwards the daemons can be restarted only on Emacs versions 24.4 and later.
Another issue with restarting Emacs daemons is that the frames open in a
terminal cannot be recreated on restart, instead the ~restart-emacs~ would
write a notification on the terminal with the instructions to reconnect, any
suggestions to improve this are welcome.
** Contributing Code as well as documentation contributions are welcome.
[[https://github.com/cask/cask][Cask]] is used to manage project dependencies so make sure you have it installed. To run the tests you need to install the dependencies by running the following
#+BEGIN_SRC sh cask install #+END_SRC
After the installation completes you can run the tests by running the following command
#+BEGIN_SRC sh cask exec ert-runner #+END_SRC
** Known Issues *** Command line arguments are not preserved The new Emacs instance does not use the same command line arguments as the running instance. See [[https://github.com/iqbalansari/restart-emacs/issues/11][#11]] for more details *** The restarted daemon quits as soon as the all the visible frames are killed See https://github.com/iqbalansari/restart-emacs/issues/10#issuecomment-307565719
