NAME

GitHub::Actions - Work in GitHub Actions using Perl

VERSION

This document describes GitHub::Actions version 0.1.1.1

SYNOPSIS

use GitHub::Actions;
use v5.14;

# Imported %github contains all GITHUB_* environment variables
for my $g (keys %github ) {
   say "GITHUB_$g -> ", $github{$g}
}

# Set step output
set_output("FOO", "BAR");

# Set environment variable value
set_env("FOO", "BAR");

# Produces an error and sets exit code to 1
error( "FOO has happened" );

# Error/warning with information on file
error_on_file( "There's foo", $file, $line, $col );
warning_on_file( "There's bar", $file, $line, $col );

# Debugging messages and warnings
debug( "Value of FOO is $bar" );
warning( "Value of FOO is $bar" );

# Start and end group
start_group( "Foo" );
# do stuff
end_group;

# Exits with error if that's the case
exit_action();

# Errors and exits
set_failed( "We're doomed" );

Install this module within a GitHub action

. name: "Install GitHub::Actions"
  run: sudo cpan GitHub::Actions

(we need sudo since we're using the system Perl)

You can use this as a step

- name: Test env variables
  shell: perl {0}
  run: |
    use GitHub::Actions;
    set_env( 'FOO', 'BAR');

In most cases, you'll want to just have it installed locally and fatpack it to upload it to the repository.

DESCRIPTION

GitHub Actions include by default, at least in its Linux runners, a system Perl which you can use directly in your GitHub actions. This here is a (for the time being) minimalistic module that tries to help a bit with that, by defining a few functions that will be useful when performing GitHub actions. Besides the system Perl, you can use any of the modules installed. You can install other modules via cpan or, preferably for speed, via the Ubuntu package (or equivalent)

Check out an example of using it in the repository

INTERFACE

set_env( $env_var_name, $env_var_value)

This is equivalent to setting an environment variable

set_output( $output_name, $output_value)

Equivalent to set_output

debug( $debug_message )

Equivalent to debug

error( $error_message )

Equivalent to error, prints an error message. Remember to call exit_action() to make the step fail if there's been some error.

warning( $warning_message )

Equivalent to warning, simply prints a warning.

command_on_file( $error_message, $file, $line, $col )

Common code for error_on_file and warning_on_file. Can be used for any future commands.

error_on_file( $error_message, $file, $line, $col )

Equivalent to error, prints an error message with file and line info

warning_on_file( $warning_message, $file, $line, $col )

Equivalent to warning, prints an warning with file and line info.

set_failed( $error_message )

Exits with an error status of 1 after setting the error message.

start_group( $group_name )

Starts a group in the logs, grouping the following messages. Corresponds to group.

end_group

Ends current log grouping.

exit_action

Exits with the exit code generated during run, that is, 1 if there's been any error reported.

CONFIGURATION AND ENVIRONMENT

GitHub::Actions requires no configuration files or environment variables. Those set by GitHub Actions will only be available there, or if you set them explicitly. Remember that they will need to be set during the BEGIN phase to be available when this module loads.

BEGIN {
  $ENV{'GITHUB_FOO'} = 'foo';
  $ENV{'GITHUB_BAR'} = 'bar';
}

DEPENDENCIES

Intentionally, no dependencies are included.

INCOMPATIBILITIES

None reported.
