path_expander

pre-process command-line arguments expanding directories into files

Description

PathExpander helps pre-process command-line arguments expanding directories into their constituent files. It further helps by providing additional mechanisms to make specifying subsets easier with path subtraction and allowing for command-line arguments to be saved in a file.

NOTE: this is NOT an options processor. It is a path processor (basically everything else besides options). It does provide a mechanism for pre-filtering cmdline options, but not with the intent of actually processing them in PathExpander. Use OptionParser to deal with options either before or after passing ARGV through PathExpander.

Features & Problems

• Processes command-line arguments.
• Expands directories into files using custom globs.
• Allows for negation of files.
• Allows for use of files as persisted args.
• Provides a .ignore mechanism for lightweight persistent exclusion.

Synopsis

class MyPathExpander < PathExpander
 MY_GLOB = "**/*.rb"
 def initialize args = ARGV
 super args, MY_GLOB
 end
end
MyPathExpander.new(ARGV, my_glob).process.each do |f|
 # do something with each file
end
