PHP Code Completion library for Phpactor.

This package includes:

• Completion APIs and implementations.
• Phpactor RPC extension and handlers.
• Language Server extension and handlers.

Usage

Each completor implements the Completor interface which accepts the source code as a string and a byte offset from which to complete from. The completor must yield instances of the Suggestion class:

$completor = new MyCompletor();
$suggestions = $completor->complete($sourceCode, $byteOffset);

/** @var Suggestion $suggestion */
foreach ($suggestions as $suggestion) {
    echo $suggestion->name();
    echo $suggestion->shortDescription();
}

Multiple completors can be chained together with the ChainCompletor:

$completor = new ChainCompletor([
    new MyCompletor1(),
    new MyCompletor2(),
]);

$suggestions = $completor->complete($sourceCode, $byteOffset);

Tolerant Completors

The library currently includes a suite of completors using the Tolerant PHP Parser and WorseReflection. All of the tolerant completors are instances of TolerantCompletorInterface and accept a parser node rather than a byte offset. They can be collected in a TolerantChainCompletor class which in turn implements the primary Completor interface:

use Phpactor\WorseReflection\ReflectorBuilder;
use Phpactor\Completion\Bridge\TolerantParser\ChainTolerantCompletor;
use Phpactor\Completion\Bridge\TolerantParser\WorseReflection\WorseLocalVariableCompletor;
use Phpactor\Completion\Bridge\TolerantParser\WorseReflection\WorseClassMemberCompletor;

$reflector = ReflectorBuilder::create()->addSource($sourceCode)->build();
$formatter = new ObjectFormatter([
    // ... instances of ObjectFormatter
]);
$completor = new ChainTolerantCompletor([
    new WorseLocalVariableCompletor($reflector, $formatter),
    new WorseClassMemberCompletor($reflector, $formatter),
]);

$completor->complete($sourceCode, $byteOffset);

Formatters

This library can format arbitrary objects as strings, for example to go from a ReflectionMethod to the synopsis: pub function($foobar).

$formatter = new ObjectFormatter([
    new TypeFormatter(),
    new TypesFormatter(),
    new FunctionFormatter(),
    new MethodFormatter(),
    new ParameterFormatter(),
    new ParametersFormatter(),
    new PropertyFormatter(),
    new VariableFormatter(),
]);

$reflectionMethod = $reflector->reflectClass(Foobar::class)->methods()->get('barfoo');
$formatter->format($reflectionMethod);

Each formatter is able to indicate if it can format a given object, and if so it is chosen.
