NAME

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

VERSION

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

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.

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.

ACME::CPANMODULES ENTRIES

  • PerlIO::fgets - Provides a fgets() like function for PerlIO file handles

    Author: CHANSEN

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

  • File::fgets - Read either one line or X characters from a file

    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.

  • File::GetLineMaxLength - Get lines from a file, up to a maximum line length

    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.

FAQ

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 Acme::CPANModules for more details.

What are ways to use this Acme::CPANModules module?

Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution):

 % cpanm-cpanmodules -n fgets

Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution):

    % cpanmodules ls-entries fgets | cpanm -n

or Acme::CM::Get:

    % perl -MAcme::CM::Get=fgets -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

or directly:

    % perl -MAcme::CPANModules::fgets -E'say $_->{module} for @{ $Acme::CPANModules::fgets::LIST->{entries} }' | cpanm -n

This Acme::CPANModules module also helps lcpan produce a more meaningful result for lcpan related-mods command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
