Pico Deprecated Changelog
=========================
**Note:** This changelog only provides technical information about the changes
introduced with a particular Pico version, and is meant to supplement
the actual code changes. The information in this changelog are often
insufficient to understand the implications of larger changes. Please
refer to both the UPGRADE and NEWS sections of the docs for more
details.
**Note:** Changes breaking backwards compatibility (BC) are marked with an `!`
(exclamation mark). This doesn't include changes for which BC is
preserved by this plugin. If a previously deprecated feature is later
removed, this change is going to be marked as BC-breaking change.
Please note that BC-breaking changes are only possible with a new
major version.
**Note:** Many versions of `PicoDeprecated` include changes which are not
explicitly mentioned in this changelog. This primarily concerns
changes in Pico's plugin API. These changes aren't listed separately
because they are already listed in Pico's changelog. Only functional
changes and/or BC-breaking changes are listed below.
### Version 2.1.4
Released: 2020-08-29
No changes
### Version 2.1.3
Released: 2020-07-10
No changes
### Version 2.1.2
Released: 2020-04-10
No changes
### Version 2.1.1
Released: 2019-12-31
No changes
### Version 2.1.0
Released: 2019-11-24
No changes
### Version 2.1.0-beta.1
Released: 2019-11-03
```
* [New] Add support for the latest API v3 changes
* [New] Support disabled Twig autoescape prior to API v3
* [New] Re-introduce `theme_url` config variable
* [New] Re-introduce `prev_page`, `base_dir` and `theme_dir` Twig variables
* [New] Support loading additional plugins using API v1 `onPluginsLoaded` event
* [New] Re-introduce Pico v0.9 config constant `CACHE_DIR`
* [New] Add release & build system to test the plugin using PHP_CodeSniffer and
to automatically create pre-built release packages
* [Changed] Split the plugin's functionality into multiple compatibility
plugins (two for each API version, for plugins and themes resp.)
and load the necessary compatibility plugins on demand only; also
allow 3rd-party plugins to load their own compatibility plugins
```
### Version 2.0.5-beta.1
Released: 2019-01-03
```
* [New] Add `2.0.x-dev` alias for master branch to `composer.json`
```
### Version 2.0.4
Released: 2018-12-17
No changes
### Version 2.0.3
Released: 2018-12-03

### Version 2.0.0-beta.3
Released: 2018-04-07
No changes
### Version 2.0.0-beta.2
Released: 2018-01-21
```
* [New] Add support for the latest API v2 changes
* [New] ! Add support for themes using the old `.html` file extension for Twig
templates; however, starting with API v2 plugins might rely on `.twig`
as file extension, making this a BC-breaking change regardless
```
### Version 2.0.0-beta.1
Released: 2017-11-05
**Note:** Pico's official `PicoDeprecated` plugin was moved to this separate
repository in preparation for Pico 2.0. Refer to Pico's changelog for
a list of changes to this plugin before Pico 2.0.
```
* [New] Update plugin to API v2 and add support for all API v1 events
* [New] Keep track of all loaded Pico plugins and distinguish them by the API
version they use; deprecated events are only triggered on plugins using
this particular API version (`PicoDeprecated::API_VERSION_*` constants)
* [New] Take care of triggering events on plugins using older API versions;
this includes not only core events, but also all custom events; as a
result, old plugin's always depend on `PicoDeprecated` now
* [New] Use a simple event alias table to keep track of unchanged or just
renamed core events
* [New] Add `rewrite_url` and `is_front_page` Twig variables
* [New] Add support for the `config/config.php` configuration file
* [New] Additionally compare registered meta headers case-insensitive
* [New] Make meta headers on the first level of a page's meta data also
available using a lowered key (as of Pico 1.0; i.e. `SomeKey: value` is
now accessible using both `$meta['SomeKey']` and `$meta['somekey']`)
* [New] Add public `PicoDeprecated::triggersApiEvents()` method
* [New] Add public `PicoDeprecated::triggerEvent()` method (and the additional
`$apiVersion` parameter) as replacement for the previously protected
method of the same name
* [Fixed] ! Don't overwrite the global `$config` variable if it is defined
* [Fixed] ! Improve re-indexing of pages added by the API v0 event `get_pages`
* [Changed] No longer try to guess whether the plugin needs to be enabled or
not, rather enable it by default (guessing was pretty error-prone)
* [Changed] ! Use a scope-isolated `require()` to include configuration files
* [Changed] ! Don't pass `$plugins` parameter to API v1 `onPluginsLoaded` event
by reference anymore; use `Pico::loadPlugin()` instead
* [Changed] ! The API v1 events `onTwigRegistration` and `onMetaHeaders`, as
well as the API v0 event `before_twig_register` are no longer part
of Pico's event flow and are triggered just once on demand
* [Changed] Improve PHP class docs
* [Changed] A vast number of small improvements and changes...
* [Removed] ! Remove support for `PicoParsePagesContent` plugin
* [Removed] ! Remove support for `PicoExcerpt` plugin
```

Pico Deprecated Plugin
======================
This is the repository of Pico's official `PicoDeprecated` plugin.
Pico is a stupidly simple, blazing fast, flat file CMS. See http://picocms.org/ for more info.
`PicoDeprecated`'s purpose is to maintain backward compatibility to older versions of Pico, by re-introducing characteristics that were removed from Pico's core. It for example triggers old events (like the `before_render` event used before Pico 1.0) and reads config files that were written in PHP (`config/config.php`, used before Pico 2.0).
Please refer to [`picocms/Pico`](https://github.com/picocms/Pico) to get info about how to contribute or getting help.
Install
-------
You usually don't have to install this plugin manually, it's shipped together with [Pico's pre-built release packages](https://github.com/picocms/Pico/releases/latest) and a default dependency of [`picocms/pico-composer`](https://github.com/picocms/pico-composer).
If you're using plugins and themes that are compatible with Pico's latest API version only, you can safely remove `PicoDeprecated` from your Pico installation or disable the plugin (please refer to the "Usage" section below). However, if you're not sure about this, simply leave it as it is - it won't hurt... :wink:
If you use a `composer`-based installation of Pico and want to either remove or install `PicoDeprecated`, simply open a shell on your server and navigate to Pico's install directory (e.g. `/var/www/html`). Run `composer remove picocms/pico-deprecated` to remove `PicoDeprecated`, or run `composer require picocms/pico-deprecated` (via [Packagist.org](https://packagist.org/packages/picocms/pico-deprecated)) to install `PicoDeprecated`.
If you rather use one of Pico's pre-built release packages, it is best to disable `PicoDeprecated` and not to actually remove it. The reason for this is, that `PicoDeprecated` is part of Pico's pre-built release packages, thus it will be automatically re-installed when updating Pico. However, if you really want to remove `PicoDeprecated`, simply delete the `plugins/PicoDeprecated` directory in Pico's install directory (e.g. `/var/www/html`). If you want to install `PicoDeprecated`, you must first create a empty `plugins/PicoDeprecated` directory on your server, [download the version of `PicoDeprecated`](https://github.com/picocms/pico-deprecated/releases) matching the version of your Pico installation and upload all containing files (esp. `PicoDeprecated.php` and the `lib/`, `plugins/` and `vendor/` directories) into said `plugins/PicoDeprecated` directory (resulting in `plugins/PicoDeprecated/PicoDeprecated.php`).
The versioning of `PicoDeprecated` strictly follows the version of Pico's core. You *must not* use a version of `PicoDeprecated` that doesn't match the version of Pico's core (e.g. PicoDeprecated 2.0.1 is *not compatible* with Pico 2.0.0). If you're using a `composer`-based installation of Pico, simply use a version constaint like `^2.0` - `PicoDeprecated` ensures that its version matches Pico's version. Even if you're using one of Pico's pre-built release packages, you don't have to take care of anything - a matching version of `PicoDeprecated` is part of Pico's pre-built release packages anyway.
Usage
-----
You can explicitly disable `PicoDeprecated` by adding `PicoDeprecated.enabled: false` to your `config/config.yml`. If you want to re-enable `PicoDeprecated`, simply remove this line from your `config/config.yml`. `PicoDeprecated` itself has no configuration options, it enables and disables all of its features depending on whether there are plugins and/or themes requiring said characteristics.
`PicoDeprecated`'s functionality is split into various so-called "compatibility plugins". There are compatibility plugins for every old API version (Pico 0.9 and earlier were using API version 0, Pico 1.0 was using API version 1 and Pico 2.0 was using API version 2; the current API version is version 3, used by Pico 2.1), one for plugins and another one for themes. Their purpose is to re-introduce characteristics plugins and themes using said API version might rely on. For example, plugin API compatibility plugins are responsible for simulating old Pico core events (like the `before_render` event used by Pico 0.9 and earlier). Theme API compatibility plugins will e.g. register old Twig variables (like the `is_front_page` Twig variable used by Pico 1.0). If you install a plugin using API version 2, the corresponding `PicoPluginApi2CompatPlugin` will be loaded. All plugin API compatibility plugins also depend on their theme counterpart, thus `PicoThemeApi2CompatPlugin` will be loaded, too. Furthermore all compatibility plugins depend on their respective API successors.
The plugin exposes a simple API to allow other plugins to load their own compatibility plugins. As a plugin developer you may use the `PicoDeprecated::loadCompatPlugin(PicoCompatPluginInterface $compatPlugin)` method to load a custom compatibility plugin. Use `PicoDeprecated::getCompatPlugins()` to return a list of all loaded compatibility plugins. You can furthermore use the `PicoDeprecated::getPlugins(int $apiVersion)` method to return a list of all loaded Pico plugins using a particular API version. If you want to trigger a custom event on plugins using a particular API version only, use `PicoDeprecated::triggerEvent(int $apiVersion, string $eventName, array $parameters = [])`. `PicoDeprecated` furthermore triggers the custom `onPicoDeprecated(PicoDeprecated $picoDeprecated)` event.
