A Linux utility for running arbitrary commands on the signal SIGUSR1.
sigpr is intended for running/restarting programs/tests during software
development making it easy to control when the program/tests are run.
The simplest usage is to start a command with sigpr run <command>, it (and
any other sigpr instances) can then be restarted from another shell,
scripts, editor commands etc. via sigpr restart.
sigpr restart is just a convenient command that simply finds all sigpr
processes and signals them with SIGUSR1, if finer control is desired you can
make scripts that kill -USR1 <sigpr pid> directly.
See sigpr help for all options and commands.
Pre-built fully statically linked binaries can be found on the release page.
Installation from source can be done with cabal install.
When developing with sigpr and vim the following config can be used to execute
restarts:
" Bind <Leader>r to execute a sigpr restart
noremap <Leader>r <cmd>silent execute '!sigpr restart'<CR>
" Run sigpr restart on file write
autocmd BufWritePost * silent execute '!sigpr restart'
