Historically it was often not quite clear to users what PHP version
Psalm assumes, and why. This PR addresses this issue by printing the
version and where we got it from right before scanning the files.
* Add documention to LSP
Add descriptions for all Classes, Functions, Methods, Class Constants for LSP methods for Hover, SignatureInformation and Completions
* Descriptions for class name completions
* PHPCS
* Fix docblock being overriden
* Remove trailing comma in args
* Add description to function param before early `continue`
* Update php-language-server-protocol to 1.5
* Break up long array docblocks
* Break up docblock onto newline

* Add completions for functions
Provide autocompletions in the LSP for all global functions and functions from namespaces used in the current context.
* Uncomment code
* PHPCS
* Simplify functions map

* Switch to storing lowercase function string in array key
* Fix spacing

* Track references on global variables
Add global type references to the type map, and fix up unused detection on global variables.
* Add null assertions
* PHPCS
* Add constant fetch to reference map
To support showing constant types on hover of constant references, we need to add them to the ref map.
* Fix root constants
* PHPCBF
* Add completions for known array keys
* Use dynamic gap value
* Provide completions for known type contexts
* Fix formatting
* Remove trailing comma
* PHPCS fixes
* Remove support for literal floats
* Fix test for floats
* Support compleitions on class references
This provides completions on class references (as opposed to initiated objects via the type map), so you can do `MyClass::` and get completitions for static methods and constants etc.
* Only provide completions for references that don't exist
* Remove file map cache when re-analyzing files
When the project is re-analyzed under the single thread condition (not using a process pool), the filemaps are not cleared before re-analyzing files. This means that file maps only get appended to. If you delete the contents of a file via the LSP, the file map will still be populated with all the old values for example.
In doing this I had to write a few more tests to check my assumptions too, so adding those additional tests.
* Rename test
* Formatting
* Formatting again!
* Run tests in random order
Being able to run tests in any order is a pre-requisite for being able
to run them in parallel.
* Reset type coverage between tests, fix affected tests
* Reset parser and lexer between test runs and on php version change
Previously lexer was reset, but parser kept the reference to the old
one, and reference to the parser was kept by StatementsProvider. This
resulted in order-dependent tests - if the parser was first initialized
with phpVersion set to 7.4 then arrow functions worked fine, but were
failing when the parser was initially constructed with settings for 7.3
This can be demonstrated on current master by upgrading to
nikic/php-parser:4.9 and running:
```
vendor/bin/phpunit --no-coverage --filter="inferredArgArrowFunction" tests/ClosureTest.php
```
Now all tests using PHP 7.4 features must set the PHP version
accordingly.
* Marked more tests using 7.4 syntax
* Reset newline-between-annotation flag between tests
* Resolve real paths before passing them to checkPaths
When checkPaths is called from psalm.php the paths are resolved, so we
just mimicking SUT behaviour here.
* Restore newline-between-annotations in DocCommentTest
* Tweak Appveyor caches
* Tweak TravisCI caches
* Tweak CircleCI caches
* Run tests in parallel
Use `vendor/bin/paratest` instead of `vendor/bin/phpunit`
* Use default paratest runner on Windows
WrapperRunner is not supported on Windows.
* TRAVIS_TAG could be empty
* Restore appveyor conditional caching
* Fix going to definition on return type
If a return type of a method or function is set incorrectly (with the PHP doc), then the references are not added for the `function() : MyClass` symbol, so the "Go to definition" feature of the LSP won't work. I don't believe an invalid return type or not should stop the symbol location being tracked (and not allowing code navigation).
In moved the symbol location tracking to be before the return early short circuit.
* Update SymbolLookupTest.php
Co-authored-by: Matthew Brown <github@muglug.com>
Currently it's not possible to "Go to definition" (LSP) on nullable args like `function( ?MyClass )` as the reference is stored a `MyClass|null` in the reference map, which will now resolve to a class name.
This PR removed any nullable type from the union before adding it to the reference map (as the reference map is only use to indicate a symbol was used in a given location, I think this makes sense).
* Implement signature help - closes#1841
* Add explicit signature count
* [LSP] Do analysis for every signatureHelp request
See here: https://github.com/vimeo/psalm/pull/1862#issuecomment-507007346
* Don’t language server information when checking property for init
* Fix signature help for functions
* Add try-catch around signature help Functions::getStorage()
