gaze-cli

CLI wrapper for the gaze file watcher. Watches files for changes, including renamed or new files, and runs a command. Can pass the filename into the command to prevent unnecessary work.

Install

npm install --save gaze-cli

Can also be installed globally.

Usage

Run gaze from your command line with a command and pattern.

See package.json for this module for an example of using gaze with npm scripts.

Run gaze --help for a full list of options.

$ gaze --help
Usage: gaze <command> <pattern> ...

If present, the string $path in <command> will be replaced by the full path to
the file that changed.

Options:
  --version        Show version number
  --help           Print this help message
  --silent         Do not print messages
  --ignore-rename  Ignore when a file is renamed

Examples:
  gaze "jshint $path" "lib/**/*.js"    Runs jshint when a js file in the lib folder changes
  gaze "jshint $path" "**/*.js" "!node_modules/**/*"    Runs jshint when any js file that is not in node_modules changes

Tips

Internally Gaze tries to use native OS events. This will only work if the number of files you are watching is less than the number of open file descriptors for your OS, otherwise it will attempt to use stat polling which often fails. You can check what this limit is with ulimit -n, if it's low you should increase it. If you get a RangeError or EMFILE error, this is probably the cause.
