• --dir, -d <dirname> Search files in <dirname> recursively

notes

in order to support searching for "deep-requires", (such as module-name/sub-module) searching for a "local" file (such as ../../module-name/sub-module) requires a leading ./ in the module name.

as a module

jut(['array', 'of', 'module', './names'], ['aliases']) -> DuplexStream

stream it filenames, and get out objects with match objects. something like:

var jut = require('jut')
  , ls = require('ls-stream') // for example
  , convert = require('dotpath-stream')
  , filter = require('stream-police')

ls('apps')
  .pipe(convert('path')) // reduce ls-stream object to path string
  .pipe(filter(function(data) {
    return /\.js$/.test(data.toString()) // only js files
  }))
  .pipe(jut(['falafel'])) // right over to jut
  .on('data', function(data) {
    console.log(data) // {filename: fullpath, line: lineNumber, module: 'falafel'}
  })
