Performance​

Pike LSP is designed for performance:

  • Parses 1000+ line files in ~15ms
  • Batch parsing for fast workspace indexing
  • Smart caching for stdlib modules
  • Request deduplication for concurrent operations
  • Lazy loading of modules

Supported File Types​

  • .pike - Pike source files
  • .pmod - Pike module files
  • .inc - Pike include files (via file association)
  • .pike files within Roxen modules
  • .rjs - Roxen JavaScript files (via file association)

Known Limitations​

Analysis Limitations​

LimitationDescription
Preprocessor DirectivesToken-based extraction for symbols in #if/#else/#endif blocks
Nested ClassesRecursive extraction up to depth 5 (configurable)
Type InferenceBasic types from literals and function signatures
Dynamic ModulesRuntime-loaded modules cannot be statically analyzed
