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 for [BSD](https://github.com/passcod/rsnotify#todo))
|
|
* 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 test
|
|
|
|
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
|
|
|
|

Use the GitHub Releases tab to obtain the binary. In the future, I'll look at adding it to Chocolatey.
