watchexec

Software development often involves running the same commands over and over. Boring!

watchexec is a simple , standalone tool that watches a path and runs a command whenever it detects modifications.

Example use cases:

Automatically run unit tests Run linters/syntax checkers Features Simple invocation and use Runs on OS X, linux and windows Monitors current directory and all subdirectories for changes (use --watch to override) Uses most efficient event polling mechanism for your platform (except forBSD) Coalesces multiple filesystem events into one, for editors that use swap/backup files during saving By default, uses .gitignore to determine which files to ignore notifications for Support for watching files with a specific extension Support for filtering/ignoring events based on glob patterns Optionally clears screen between executions Optionally restarts the command with every modification (good for servers) Does not require a language runtime Anti-Features Not tied to any particular language or ecosystem Does not require a cryptic command line involving xargs Usage Examples

Watch all javascript, CSS and HTML files in the current directory and all subdirectories for changes, running make when a change is detected:

$ watchexec --exts js,css,html make

Watch all files below src and subdirectories for changes, running make test when a change is detected:

$ watchexec --watch src make test

Call make test when any file changes in this directory/subdirectory, except for everything below target :

$ watchexec -i target make

Call/restart python server.py when any Python file in the current directory (and all subdirectories) changes:

$ watchexec -e py -r python server.py

Run make when any file changes, using the .gitignore file in the current directory to filter:

$ watchexec make Installation OS X with Homebrew

$ brew install https://raw.githubusercontent.com/mattgreen/watchexec/master/pkg/brew/watchexec.rb Credits notify for doing most of the heavy-lifting
