FileCrawler

Installation

Add this line to your application's Gemfile:

gem 'file_crawler'

And then execute:

$ gem install file_crawler

Usage

• Create Instance

finder = FileCrawler::Finder.new

• Find directories

path = '.'

finder.search(path)
p finder.directories #=> ["./bin", "./lib", "./spec", ...]
p finder.dirs #=> ["./bin", "./lib", "./spec", ...] # directories's shortname

finder.search(path, maxdepth: 1)
p finder.dirs #=> ["./bin", "./lib", "./spec"]

finder.search(path, maxdepth: 1, grep: 'sample')
p finder.dirs #=> []

• Create groups per label decided by directory name

# collect use `directories`
# directories = ['/path/path1/[abcd] defg', '/path/path2/(abcd) defg', '/path/path1/test 123', ...
finder.collect(regexs: ['[]', '()'])
p finder.collections
#=> { 'abcd': ['/path/path1/[abcd] defg', '/path/path2/(abcd) defg'], 'test 123': ['/path/path1/test 123'], ... }

• Move directory to destination

# move use `directories` or `collections`
# files = #=> ["./bin", "./lib", ...]
destination = '/var'
finder.move(destination)

# ensure destination
# [ [from, to], ... ]
p finder.targets #=> [["./bin", "/var/bin"] , ["./lib", "/var/lib"], ...]

# command output
p finder.output_mv #=> [ "mv ./bin /var/bin", "mv ./lib /var/lib", ...]

# run
finder.move(destination, dry_run: false)

• Chain

finder.search(source, grep: 'sample').collect(regexs: ['[]']).move(destination)
