NAME
File::LsColor - Colorize input filenames just like ls does
SYNOPSIS
use File::LsColor qw(:all);
# Is equal to:
use File::LsColor qw(
ls_color
ls_color_custom
ls_color_default
ls_color_internal
);
my @files = glob("$ENV{HOME}/*");
print ls_color($_), "\n" for(@files);
# or specify own pattern
@files = ls_color_custom('*.pl=38;5;196;1:*.pm=38;5;220', @files);
# or use the internal mappings
@files = ls_color_internal(@files);
# or use the defaults (only ANSI colors)
@files = ls_color_default(@files);
# returns a hashref with all defined filetypes and their attributes
my $ls_colors = get_ls_colors();
# what's the defined attributes for directories?
my $dir_color = lookup_ls_color('di');
get_ls_colors()
DESCRIPTION
This module provides functionality for using the LS_COLORS variable for
colorizing output in a way that's immediately recognized.
Say that you have a list of filenames that's the result of some complex
operation, and you wish to present the result to the user.
If said files have an extension and that extension is present in the
users LS_COLORS variable, they will be colored just like they would have
been if the filenames were output from ls(1) or tree(1).
EXPORTS
None by default.
FUNCTIONS
ls_color()
Arguments: @files | \@files
Returns: $files | @files
Returns a list of filenames colored as specified by the environment
"LS_COLORS" variable. If the "LS_COLORS" variable is not set, throws an
exception. In this case, "ls_color_internal()" can be used.
In scalar context a string joined by '' is returned.
ls_color_default()
The same thing as "ls_color()", but uses the default LS_COLORS values
from GNU ls. Those are only ANSI colors.
ls_color_internal()
The same as "ls_color()", with one minor difference; Instead of using
the LS_COLORS variable from the environment, an internal specification
is used. This specification contains about 250 extensions as of this
writing.
ls_color_custom()
The first argument to "ls_color_custom()" should be a valid LS_COLORS
definition, like so:
ls_color_custom("*.pl=38;5;196:*.pm=38;5;197;1", @perl_files);
get_ls_colors()
Returns a hash reference where a key is the extension and its value is
the attributes attached to it.
lookup_ls_color(), ls_color_lookup()
Given a valid name, returns the defined attributes associated with it.
Else, returns undef.
