Configuration received from the client via initializationOptions.

Fields

php_version: Option<String>

PHP version string, e.g. "8.1". Set explicitly via initializationOptions or auto-detected from composer.json / the php binary at startup.

exclude_paths: Vec<String>

Glob patterns for paths to exclude from workspace indexing.

include_paths: Vec<String>

Glob patterns for paths that must be indexed even if they match an excludePaths entry. Patterns are matched against path components (same semantics as excludePaths). Example: ["vendor/yiisoft"].

diagnostics: DiagnosticsConfig

Per-category diagnostic toggles.

features: FeaturesConfig

Per-feature capability toggles.

max_indexed_files: usize

Hard cap on the number of PHP files indexed during a workspace scan. Defaults to MAX_INDEXED_FILES. Set lower via initializationOptions to reduce memory on projects with very large vendor trees.

index_vendor: bool

Whether to eagerly index vendor/ during the workspace scan.

Default false: vendor/ is skipped on scan; vendor files load on demand via PSR-4 resolution (composer autoload + per-file parse). This keeps $/php-lsp/indexReady fast on real-world projects where vendor dwarfs the workspace.

Set true for full workspace-symbol coverage of vendor and find- implementations / type-hierarchy against vendor types — at the cost of a slower initial scan.

debug: bool

Emit extra diagnostic log messages on startup: cache hit/miss ratio, workspace root paths, and PSR-4 namespace count. Enable via initializationOptions.debug = true.

debounce_ms: u64

Debounce delay in milliseconds between the last textDocument/didChange and the parse + analysis run. Defaults to 100 ms. Set lower for fast machines / Neovim users; set higher for slow machines or large files to reduce thrashing.

warm_analysis: bool

Background-analyze the workspace after indexing (and re-warm after edits settle) so find-references / rename answer from warm memos instead of paying a cold per-file analysis at request time. Default true; set warmAnalysis: false to trade slower references for a smaller resident footprint.

cache_path: Option<PathBuf>

Override the on-disk cache directory. When set, used verbatim (no schema-version or workspace-hash subdirectories appended). Primarily useful in tests and CI environments with non-standard cache locations. When absent, falls back to the platform default ($XDG_CACHE_HOME / $HOME/.cache on Unix, %LOCALAPPDATA% on Windows).

flush_interval_ms: u64

How often the background loop persists staged analysis-cache postings (reference postings from an in-progress warm sweep or an on-demand query freshness pass) to disk. Bounds data loss on an unclean exit (crash, kill — anything that skips shutdown) to roughly one interval. Defaults to 20 s; lower mainly useful in tests.
