  Returns TreeSitterExecutor

StaticinitTreeSitter

• initTreeSitter(
      config?: TreeSitterEngineConfig,
      overrideWasmPath?: string,
      overrideTreeSitterWasmPath?: string,
  ): Promise<void>

  Initializes the underlying tree-sitter parser. This only needs to be called once globally.

  Parameters

  • Optionalconfig: TreeSitterEngineConfig

    The configuration for the tree-sitter engine, which can include paths to the wasm files.

  • OptionaloverrideWasmPath: string

    The path to the tree-sitter-r wasm file, which takes precedence over the config and default paths if set.

  • OptionaloverrideTreeSitterWasmPath: string

    The path to the tree-sitter wasm file, which takes precedence over the config and default paths if set.

  Returns Promise<void>

StaticisInitialized

• isInitialized(): boolean

  Whether initTreeSitter has loaded the R grammar, which every parser needs.

  Returns boolean

close

• close(): void

  Returns void

createQuery

• createQuery(source: string): Query

  Parameters

  • source: string

  Returns Query

information

• information(analyzer: ReadonlyFlowrAnalysisProvider): TreeSitterInformation

  Parameters

  • analyzer: ReadonlyFlowrAnalysisProvider

  Returns TreeSitterInformation

parse

• parse(
      request: RParseRequest & { filePath?: string },
      ctx: FlowrAnalyzerContext,
  ): Tree

  Parses the given request and uses the provided context (only if the parser itself supports incrementality ParserContent#incremental).

  Parameters

  • request: RParseRequest & { filePath?: string }
  • ctx: FlowrAnalyzerContext

  Returns Tree

parseCode

• parseCode(code: string): Tree

  Parses code that belongs to no analysis, like the sources of a package, without incremental reparsing.

  Parameters

  • code: string

  Returns Tree

query

• query(source: string | Query, ...tree: readonly Tree[]): QueryCapture[]

  Parameters

  • source: string | Query
  • ...tree: readonly Tree[]

  Returns QueryCapture[]

rVersion

• rVersion(): Promise<string>

  Returns Promise<string>

treeSitterVersion

• treeSitterVersion(): number

  Returns number
