# Restoring programs
|
|
|
|
Only a conservative list of programs is restored by default:<br/>
|
|
`vi vim nvim emacs man less more tail top htop irssi mutt`.
|
|
|
|
This can be configured with `@resurrect-processes` option in `.tmux.conf`. It
|
|
contains space-separated list of additional programs to restore.
|
|
|
|
- Example restoring additional programs:
|
|
|
|
set -g @resurrect-processes 'ssh psql mysql sqlite3'
|
|
|
|
- Programs with arguments should be double quoted:
|
|
|
|
set -g @resurrect-processes 'some_program "git log"'
|
|
|
|
- Start with tilde to restore a program whose process contains target name:
|
|
|
|
set -g @resurrect-processes 'irb pry "~rails server" "~rails console"'
|
|
|
|
- Use `->` to specify a command to be used when restoring a program (useful if
|
|
the default restore command fails ):
|
|
|
|
set -g @resurrect-processes 'some_program "grunt->grunt development"'
|
|
|
|
- Don't restore any programs:
|
|
|
|
set -g @resurrect-processes 'false'
|
|
|
|
- Restore **all** programs (be careful with this!):
|
|
|
|
set -g @resurrect-processes ':all:'
|
|
|
|
### Clarifications
|
|
|
|
> I don't understand tilde `~`, what is it and why is it used when restoring
|
|
programs?
|
|
|
|
Let's say you use `rails server` command often. You want `tmux-resurrect` to
|
|
save and restore it automatically. You might try adding `rails server` to the
|
|
list of programs that will be restored:
|
|
|
|
set -g @resurrect-processes '"rails server"' # will NOT work
|
|
|
|
Upon save, `rails server` command will actually be saved as this command:
|
|
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server`
|
|
(if you wanna see how is any command saved, check it yourself in
|
|
`~/.tmux/resurrect/last` file).
|
|
|
|
When programs are restored, the `rails server` command will NOT be restored
|
|
because it does not **strictly** match the long
|
|
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server` string.
|
|
|
|
The tilde `~` at the start of the string relaxes process name matching.
|
|
|
|
set -g @resurrect-processes '"~rails server"' # OK
|
|
|
|
The above option says: "restore full process if `rails server` string is found
|
|
ANYWHERE in the process name".
|
|
|
|
If you check long process string, there is in fact a `rails server` string at
|
|
the end, so now the process will be successfully restored.
|
|
|
|
> What is arrow `->` and why is is used?
|
|
|
|
(Please read the above clarification about tilde `~`).
|
|
|
|
Continuing with our `rails server` example, when the process is finally restored
|
|
correctly it might not look pretty as you'll see the whole
|
|
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server` string in
|
|
the command line.
|
|
|
|
Naturally, you'd rather want to see just `rails server` (what you initially
|
|
typed), but that information is now unfortunately lost.
|
|
|
|
To aid this, you can use arrow `->`:
|
|
|
|
set -g @resurrect-processes '"~rails server->rails server"' # OK
|
|
|
|
This option says: "when this process is restored use `rails server` as the
|
|
command name".
|
|
|
|
Full (long) process name is now ignored and you'll see just `rails server` in
|
|
the command line when the program is restored.
