watch-interface

Recursively gather file meta data starting at a root directory. When files change the meta data gets automatically updated. It is thin wrapper for gaze that takes care of some housekeeping and provides a non-changing interface when we change the watching backend.

Usage

require('watch-interface').on(directory, options, callback)

Starts watching a directory recursively.

• directory: String, root of what should be watched
• options: Object with
  • exclude: Array of strings, regular expressions or functions that should match if the particular file should be ignored.
• callback: gets err object and a gazer

require('watch-interface').onFiles(directory, listOfFiles, options, callback)

Like on but ignore all files except those that are in the list.

gazer.state

• object with the fields
  • monitor: gazer object from the gaze module
  • lastChange: Date
  • startTime: Date
  • changeList: list of changes accrued since startTime, having the fields:
    • time
    • path
    • type: one of ["creation", "removal", "change"]

gazer.getWatchedFiles(callback)

Retrieve all the files being watched.

• callback is called with an error object and and array of files (file paths, relative to the base directory being watched)

gazer.getChangesSince(date, callback)

Retrieve what changes happened since a given time.

• date: Request changes since. Date object or Number specifying a data. If null, returns all changes observed.
• callback is called with two args: err and [{time,path,type}] with type one of ['removal', 'creation', 'change']

gazer.close(callback)

Stop watching.

• callback: gets err argument.
