Re-run command-line every time any files are updated in the current directoryor its subdirectories.
Project description
Usage
rerun [command]
e.g:
rerun python -m unittest mypackage.mymodule
will rerun your tests every time you save your source code. Handy for seeing the new test results in a console window after you hit ‘save’ in your editor, without having to change window focus.
For options, see:
rerun --help
It detects changes to files by polling file modification times once per second. On detecting any changes, it clears the terminal and then reruns the given command once.
Polling for modification times perhaps isn’t ideal. Registering of OS-specific notifications of file system events might be better. In practice though, I haven’t noticed it burden my machine, even in project directories containing hundreds of files.
It ignores directories called .svn, .git, .hg, .bzr, build and dist. It ignores files ending with .pyc or .pyo.
Dependencies
Tested on WindowsXP, Windows 7, MacOSX, and Ubuntu.
Runs under Python2.7 or 3.2.
No other dependencies.
Install
pip install rerun
Thanks
The idea came from the bash command ‘watch’, and inspiration for this implementation came from an old blog post by Jeff Winkler, whos website http://jeffwinkler.net seems to have now died.
