App::Ack - A container for functions for the ack program


Version 1.36


If you want to know about the ack program

No user-serviceable parts inside. ack is all that should use this.


is_filetype( $filename, $filetype )

Asks whether $filename is of type $filetype.


Standard filter to pass as a File::Next descend_filter. It returns true if the directory is any of the ones we know we want to skip.

filetypes( $filename )

Returns a list of types that $filename could be. For example, a file foo.pod could be "perl" or "parrot".

The filetype will be undef if we can't determine it. This could be if the file doesn't exist, or it can't be read.

It will be '-ignore' if it's something that ack should always ignore, even under -a.


Returns a list of all the types that we can detect.
