Gitdoc

Building pages from a composer.json file

This plugin collects and creates pages that contain content to the official Github documentation README of dependencies in a composer file.

generator.php

This plugin requires that the generator.php has to be run from the PHP command line in a terminal environment.

After modifying the generator.php file, which can be found in folder <GRAV Root folder>/user/plugins/gitdoc, you're good to go.

What has to be modified

define( "PAGE_FOLDER", PAGE_ROOT . "/05.slim/04.composer-package-documentation" ); /* (1) */
define( "COMPOSER_JSON", dirname( __FILE__ ) . "/composer/composer.json" ); /* (2) */

1. This is the root folder in the /user/pages/ under which the pages will be generated.
2. The location of the composer.json file. You can copy your composer.json file to be examined and generated to this folder. You can simply create a folder composer under the root of your GRAV folder.

Generating the files

Now you do from the root folder of the plugin in a terminal:

php generator.php
