* add ability to load plugins by class names
- Plugins need to implement `__invoke(PluginFacade $psalm):void` method
- Plugins are enabled by adding `<pluginClass
class="Qualified\Class\Name"/>`
- `PluginFacade` provides a single point of contact with Psalm, so that
plugins cannot become coupled to Psalm internals
* added `psalm-plugin` cli tool to manage plugins
Available commands:
`psalm-plugin list` - lists available and enabled plugins
`psalm-plugin enable 'Plugin\Class\Name'` - enables plugin (modifies `psalm.xml`)
`psalm-plugin disable 'Plugin\Class\Name'` - disables plugin (modifies `psalm.xml`)
Plugin installation:
`composer install plugin-vendor/plugin-package-name`
Plugin authoring:
Plugins are identified by package `type` field, which should contain
`psalm-plugin` string.
`extra.pluginClass` should refer to the name of the class implementing
`__invoke(PluginFacade $psalm):void` function
Todo:
- better config file search
- better output for `psalm-plugin`
- better formatting for modified xml file
- composer skeleton project for plugins
- ability to refer to plugins by package name (cli only)
- composer plugin to (optionally) enable plugin upon installation
- documentation on plugin installation and authoring
- interfaces for plugin dependencies
- interface for plugin entry point
- migration path for legacy plugins
* documented previously undocumented plugin methods
* split legacy plugin registration into a wrapper class
also added `PluginApi` namespace and `RegistrationInterface`
* reuse psalm's config search algorithm
* enable/disable plugins by composer package name
* allow specifying alternative config file name
* whitelist PluginApi namespace
three times, but well, it works now
* interface for plugin entry points
* psalm-plugin as a symfony console app
* fixed errors found by psalm
* suppressed false positive UnusedMethods
* cs fix
* better psalm-plugin output
* don't leave empty `plugins` node to avoid old schema violation
* removed junk file that shouldn't be there
* cs fix
* fixed phpunit failure (constant redefinition)
* work around missing docblock in on symfony console
* php 7.0 compatibility
* allow `pluginClass` child elements as plugin configuration
* decouple console commands from undelying implementation
- introduce PluginListFactory
- add `PluginList::enable(string $class)` and `PluginList::disable(string $class)`
* PluginList tests
* ComposerLock test
* droppped debugging statement
* added part of console command tests
* added tests for EnableCommand
* added DisableCommand tests
* ignore unused args
* ConfigFile test
* disable travis cache in attempt to fix builds
* nah, that didn't work
* update for upstream changes
* rebase fixes
* namespaced `extra` entry for entry point
* s/PluginFacade/PluginRegistrationSocket/g
* Added $config parameter to PluginEntryPointInterface::__invoke()
* cs fixes
* entry point interface php7.0 compatibility
* cleaned up old cruft
- dropped todos I'm not going to pursues
- locked entry point to be a class implementing entry point interface
* fixed legacy plugins docs
* Added RegistrationInterface::registerHooksFromClass()
It mimics the way old plugins were registered in Psalm\Config, so
handler classes extending Psalm\Plugin should be fully compatible with
it.
Since Psalm\Plugin-style plugin registration was moved to
RegistrationSocket, LegacyPlugin now only load file-based plugins, so it
was renamed to FileBasedPluginAdapter.
* Converted EchoChecker plugin to composer-based format
- Its subfolder is registered as a local composer package in the root
composer.json, so it's directly installable with
```
composer require psalm/echo-checker-plugin
```
- Migration is trivial: drop the plugin into a separate folder, then add
simple composer.json and the entry point class.
* Updated docs
* Don't reject hook handlers that inherit handling methods
* strip void return type in stub file
* Group changes
* Don’t worry about vars defined before exiting
* Fix issues with vars defined in conditionals
* Add failing test
* Only add failed reconciliation flag if nothing could be salvaged
* Avoid notice when removing clauses
* Improve handling of loops
* Fix evaluation of binary op expressions
* Remove unset vars from outer context after loop
* Ignore RedundantCondition in some more configs
