NAME

lint-prereqs - Check extraneous/missing prerequisites in dist.ini

VERSION

This document describes version 0.25 of lint-prereqs (from Perl distribution App-LintPrereqs), released on 2015-04-11.

SYNOPSIS

Usage:

 % lint-prereqs [options]

DESCRIPTION

Check [Prereqs / *] (as well as OSPrereqs, Extras/lint-prereqs/Assume-*) sections in your dist.ini against what's actually being used in your Perl code (using Perl::PrereqScanner::Lite) and what's in Perl core list of modules. Will complain if your prerequisites are not actually used, or already in Perl core. Will also complain if there are missing prerequisites.

Designed to work with prerequisites that are manually written. Does not work if you use AutoPrereqs.

Sometimes there are prerequisites that you know are used but can't be detected by scan_prereqs, or you want to include anyway. If this is the case, you can instruct lint_prereqs to assume the prerequisite is used.

 ;!lint-prereqs assume-used # even though we know it is not currently used
 Foo::Bar=0
 ;!lint-prereqs assume-used # we are forcing a certain version
 Baz=0.12

Sometimes there are also prerequisites that are detected by scan_prereqs, but you know are already provided by some other modules. So to make lint-prereqs ignore them:

 [Extras / lint-prereqs / assume-provided]
 Qux::Quux=0

OPTIONS

* marks required options.

Configuration options

--config-path=filename

Set path to configuration file.

Can be specified multiple times.

--config-profile=s

Set configuration profile to use.

--no-config

Do not use any configuration file.

Logging options

--debug

Set log level to debug.

--log-level=s

Set log level.

--quiet

Set log level to quiet.

--trace

Set log level to trace.

--verbose

Set log level to info.

Output options

--format=s

Choose output format, e.g. json, text.

Default value:

 undef
--json

Set output format to json.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:

    [1,2,3]

Other options

--help, -h, -?

Display help message and exit.

--no-lite

Use Perl::PrereqScanner instead of Perl::PrereqScanner::Lite.

Lite is faster but it might still miss detecting some modules.

--perl-version=s

Perl version to use (overrides scan_prereqs/dist.ini).

--version, -v

Display program's version and exit.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

 complete -C lint-prereqs lint-prereqs

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.

tcsh

To activate tcsh completion for this script, put:

 complete lint-prereqs 'p/*/`lint-prereqs`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

ENVIRONMENT

  • LINT_PREREQS_OPT

    Specify additional command-line options

CONFIGURATION FILE

This script can read configuration file, which by default is searched at ~/.config/lint-prereqs.conf, ~/lint-prereqs.conf or /etc/lint-prereqs.conf (can be changed by specifying --config-path). All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

Configuration file is in the format of IOD, which is basically INI with some extra features.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

List of available configuration parameters:

 format (see --format)
 lite (see --no-lite)
 log_level (see --log-level)
 naked_res (see --naked-res)
 perl_version (see --perl-version)
