NAME

File::LoadLines - Load lines from file

SYNOPSIS

use File::LoadLines;

my @lines = loadlines("mydata.txt");
...

DESCRIPTION

File::LoadLines provides an easy way to load the contents of a text file into an array of lines. It is intended for relatively small files like config files that are often produced by weird tools (and users).

It automatically handles ASCII, Latin-1 and UTF-8 text. When the file has a BOM, it handles UTF-8, UTF-16 LE and BE, and UTF-32 LE and BE.

Recognized line terminators are NL (Unix, Linux), CRLF (DOS, Windows) and CR (Mac)

EXPORT

loadlines

FUNCTIONS

loadlines

my @lines = loadlines("mydata.txt");
my @lines = loadlines("mydata.txt", $options);

Basically, the file is opened, read, decoded and split into lines that are returned in the result array. Line terminators are removed.

In scalar context, returns an array reference.

The first argument may be the name of a file, an opened file handle, or a reference to a string that contains the data.

The second argument can be used to influence the behaviour. It is a hash reference of option settings.

Note that loadlines() is a slurper, it reads the whole file into memory and requires temporarily memory for twice the size of the file.

split

Enabled by default.

If set to zero, the data is not split into lines but returned as a single string.

chomp

Enabled by default.

If set to zero, the line terminators are not removed from the resultant lines.

encoding

If specified, loadlines() will use this encoding to decode the file data if it cannot automatically detect the encoding.

If you pass an options hash, File::LoadLines will set encoding to the encoding it detected and used for this file data.

SEE ALSO

There are currently no other modules that handle BOM detection and line splitting.

I have a faint hope that future versions of Perl and Raku will deal with this transparently, but I fear the worst.

HINTS

When you have raw file data (e.g. from a zip), you can use loadlines() to decode and unpack:

open( my $data, '<', \$contents );
$lines = loadlines( $data, $options );
