phan/phan 2.0.0-RC1

Release 2.0.0-RC1 supporting PHP 7.0-7.3 syntax

on PHP Packagist

The Phan 2.x releases support analysis of php 7.0-7.3, and can be executed with php 7.1+.

New features(CLI, Configs):

• Enable language server features by default. (#2358)
  --language-server-disable-go-to-definition, --language-server-disable-hover, and --language-server-disable-completion
  can be used to disable those features.

Backwards Incompatible Changes:

• Drop support for running Phan with PHP 7.0. (PHP 7.0 reached its end of life in December 2018)
  Analyzing codebases with --target-php-version 7.0 continues to be supported.
• Require php-ast 1.0.1 or newer (or the absence of php-ast with --allow-polyfill-parser)
  Phan switched from using AST version 50 to version 70.

Plugins:

• Change PluginV2 to PluginV3
PluginV2 and its capabilities will continue to work to make migrating to Phan 2.x easier, but PluginV2 is deprecated and will be removed in Phan 3.

  PluginV3 has the same APIs and capabilities as PluginV2, but uses PHP 7.1 signatures (void, ?MyClass, etc.)

• Third party plugins may need to be upgraded to support changes in AST version 70, e.g. the new node kinds AST_PROP_GROUP and AST_CLASS_NAME

• Add PHPDocToRealTypesPlugin to suggest real types to replace (or use alongside) phpdoc return types.
  This does not check that the phpdoc types are correct.

  --automatic-fix can be used to automate making these changes for issues that are not suppressed.

• Add PHPDocRedundantPlugin to detect functions/methods/closures where the doc comment just repeats the types in the signature.
  (or when other parts don't just repeat information, but the @return void at the end is redundant)

• Add a BeforeAnalyzePhaseCapability. Unlike BeforeAnalyzeCapability, this will run after methods are analyzed, not before.
