File::Read - Unique interface for reading one or more files
Version 0.0801
use File::Read;
# read a file
$file = read_file($path);
# read several files
@files = read_files(@paths);
# aggregate several files
$file = read_files(@paths);
# read a file as root, skip comments and blank lines
$file = read_file({ as_root => 1, skip_comments => 1, skip_blanks => 1 }, $path);
This module mainly proposes functions for reading one or more files, with different options. See below for more details and examples.
This module was created to address a quite specific need: reading many
files, some as a normal user and others as root, and eventually do a
little more processing, all while being at the same time compatible
with Perl 5.004. File::Slurp addresses the first point, but not the
others, hence the creation of File::Read. If you don't need reading
files as root or the post-processing features, then it's faster to
directly use File::Slurp.
By default, this module exports all the functions documented afterhand. It also recognizes import options. For example
use File::Read 'err_mode=quiet';
set read_file()'s err_mode option default value to "quiet".
Read the files given in argument and return their content, as as list, one element per file, when called in list context, or as one big chunk of text when called in scalar context. Options can be set using a hashref as first parameter.
Options
aggregate controls how the function returns the content of the files
that were successfully read. By default, When set to true (default),
the function returns the content as a scalar; when set to false, the
content is returned as a list.
as_root tells the function to read the given file(s) as root using
the command indicated by the cmd option.
cmd sets the shell command used for reading files as root. Default
is "sudo cat". Therefore you need sudo(8) and cat(1) on your
system, and sudoers(5) must be set so the user can execute cat(1).
err_mode controls how the function behaves when an error occurs.
Available values are "croak", "carp" and "quiet".
Default value is "croak".
skip_comments tells the functions to remove all comment lines from
the read files.
skip_blanks tells the functions to remove all blank lines from
the read files.
to_ascii tells the functions to convert the text to US-ASCII using
Text::Unidecode. If this module is not available, non-ASCII data
are deleted.
Examples
Just read a file:
my $file = read_file($path);
Read a file, returning it as list:
my @file = read_file({ aggregate => 0 }, $path);
Read a file, skipping comments:
my $file = read_file({ skip_comments => 1 }, $path);
Read several files, skipping blank lines and comments:
my @files = read_file({ skip_comments => 1, skip_blanks => 1 }, @paths);
read_files() is just an alias for read_file() so that it look more
sane when reading several files.
Bad value '%s' for option '%s'
(E) You gave a bad value for the indicated option. Please check the documentation for the valid values.
This function needs at least one path
(E) You called a function without giving it argument.
