php-lsp 0.29.0

//! Laravel framework support.
//!
//! Beyond generic PHP analysis, Laravel projects lean heavily on stringly-typed
//! lookups — `env('KEY')`, `config('a.b.c')`, `view('a.b')`, `route('name')`,
//! `trans('a.b')`, `asset('a/b')`, `->middleware('alias')` — that resolve
//! against files elsewhere in the project rather than through normal symbol
//! resolution. `LaravelIndex` builds a workspace-scan-time index for each of
//! these domains and wires them into go-to-definition
//! ([`resolve_string_key`]), completion ([`completions_for_string_key`]),
//! hover ([`hover_for_string_key`]) and document links ([`document_links`]).
//!
//! Gated behind [`LaravelIndex::load`]'s project-detection check, so
//! non-Laravel workspaces pay no cost beyond the one-time
//! `artisan`/`composer.json` probe: every dispatch function bails out on the
//! `is_laravel` flag before doing any string scanning.
