/**
|
|
* Composer plugin that allows merging multiple composer.json files.
|
|
*
|
|
* When installed, this plugin will look for a "merge-plugin" key in the
|
|
* composer configuration's "extra" section. The value for this key is
|
|
* a set of options configuring the plugin.
|
|
*
|
|
* An "include" setting is required. The value of this setting can be either
|
|
* a single value or an array of values. Each value is treated as a glob()
|
|
* pattern identifying additional composer.json style configuration files to
|
|
* merge into the configuration for the current compser execution.
|
|
*
|
|
* The "autoload", "autoload-dev", "conflict", "provide", "replace",
|
|
* "repositories", "require", "require-dev", and "suggest" sections of the
|
|
* found configuration files will be merged into the root package
|
|
* configuration as though they were directly included in the top-level
|
|
* composer.json file.
|
|
*
|
|
* If included files specify conflicting package versions for "require" or
|
|
* "require-dev", the normal Composer dependency solver process will be used
|
|
* to attempt to resolve the conflict. Specifying the 'replace' key as true will
|
|
* change this default behaviour so that the last-defined version of a package
|
|
* will win, allowing for force-overrides of package defines.
|
|
*
|
|
* By default the "extra" section is not merged. This can be enabled by
|
|
* setitng the 'merge-extra' key to true. In normal mode, when the same key is
|
|
* found in both the original and the imported extra section, the version in
|
|
* the original config is used and the imported version is skipped. If
|
|
* 'replace' mode is active, this behaviour changes so the imported version of
|
|
* the key is used, replacing the version in the original config.
