Reading a line of data from a filehandle in Perl is easy, but Perl will happily
slurp line of any length without limit, even gigabytes which can cause your
script or system to run out of memory.

`fgets()` is a standard I/O C function to get a line of data with a length
limit. In many cases you don't need in this Perl but in some cases you do. The
lack of built-in `fgets()` function in Perl (unlike in, say, PHP) is a bit
annoying, but no worries because there are several CPAN modules that provide you
with just that.

low-throughput situation. Doesn't work well in non-blocking mode.

Acme::CPANModules::fgets - List of fgets() implementations in Perl

=head1 VERSION

This document describes version 0.003 of Acme::CPANModules::fgets (from Perl distribution Acme-CPANModules-fgets), released on 2022-03-18.

=head1 DESCRIPTION

Reading a line of data from a filehandle in Perl is easy, but Perl will happily
slurp line of any length without limit, even gigabytes which can cause your
script or system to run out of memory.

C<fgets()> is a standard I/O C function to get a line of data with a length
limit. In many cases you don't need in this Perl but in some cases you do. The
lack of built-in C<fgets()> function in Perl (unlike in, say, PHP) is a bit
annoying, but no worries because there are several CPAN modules that provide you
with just that.

=item * L<PerlIO::fgets> - Provides a C<fgets()> like function for PerlIO file handles

Author: L<CHANSEN|https://metacpan.org/author/CHANSEN>

Can handle piped command fine, but doesn't work well in non-blocking mode.


=item * L<File::fgets> - Read either one line or X characters from a file

Author: L<MSCHWERN|https://metacpan.org/author/MSCHWERN>

XS module. Seems to have trouble dealing with piped command. But works well in
low-throughput situation as well as in non-blocking mode.


=item * L<File::GetLineMaxLength> - Get lines from a file, up to a maximum line length

Author: L<ROBM|https://metacpan.org/author/ROBM>

Pure-Perl module. Different interface (use an OO wrapper) so a bit more
cumbersome to use. Uses a fixed 4096-byte block size so doesn't work well in
low-throughput situation. Doesn't work well in non-blocking mode.

=head2 What is an Acme::CPANModules::* module?

An Acme::CPANModules::* module, like this module, contains just a list of module
names that share a common characteristics. It is a way to categorize modules and
document CPAN. See L<Acme::CPANModules> for more details.
