Sentry

Sentry is a simple node tool to watch for file changes (using a path, wildcards, or regexes) and execute a function or shell command. It's like a watchr or guard for node.

Installation

$ npm install sentry

Example

sentry = require 'sentry'

# Watch changes in file.js
sentry.watch 'file.js', (file) -> console.log "A change has been made in #{file}"

# Watch changes on any file ending in .coffee one directory deep
sentry.watch 'fld/*.coffee', ->

# Watch changes recursively on any files 
sentry.watch 'fld/**/*', ->

# Watch files recursively that match a regex
sentry.watchRegExp 'fld/', /regex/, ->

# If you pass a string instead of a function it'll execute that child process
sentry.watch 'file.coffee', 'coffee -c'

API

Sentry comes with two methods watch and watchRegExp.

sentry.watch(filePath, [task], callback)

Optionally you may pass a task which will send (err, stdout, stderr) as the arguments to the callback

sentry.watch 'file.js', 'coffee -c', (err, stdout, stderr) ->

Or simply just a callback and Sentry will pass the filename to the callback

sentry.watch 'file.js', (filename) ->

Feel free to use wildcards with extensions


# Find all files one directory deep
sentry.watch '/folder/*', ->

# Find all files one directory deep ending in .coffee
sentry.watch '/folder/*.coffee', ->

# Find all files recursively
sentry.watch '/folder/**/*', ->

# Find all files recursively ending in .txt
sentry.watch '/folder/**/*.txt', ->

sentry.watchRegExp(root, regex, [task], callback)

Just like sentry.watch but instead you must pass a root directory and regular expression to match files against.


# Find all files in this folder that end in .coffee
sentry.watchRegExp '', /\.coffee$/, ->

# Find all files in the adjacent 'test' folder that begin with test and end in .coffee
sentry.watchRegExp '../tests/', /^test_,.coffee$/, ->

To run tests

Sentry uses Jasmine-node for testing. Simply run the jasmine-node command with the coffeescript flag

jasmine-node spec --coffee
