scalex

Fast Scala and Java symbol search without build servers

Finds definitions, implementations, references, and type hierarchies across Scala and Java codebases in seconds. Eliminates slow IDE build servers, manual grep guesswork, and repeated file reading when exploring unfamiliar code. Caches indexes by git hash so follow-up queries run instantly, and renders architecture diagrams as ASCII art.

Frequently Asked Questions

FAQPage Schema
How to install Scalex?▼

Run `npx skills add nguyenyou/scalex --all -g -y` in your terminal to install all skills in this suite globally.

How to find code definitions without an IDE?▼

Scalex parses Scala and Java source files directly, so you can find definitions, implementations, and references without a build server or compilation.

Is Scalex better than grep for Scala code?▼

Yes. It understands Scala syntax, so it finds actual symbols with categorized references and inheritance trees instead of raw text matches.

Does Scalex work with Claude Code and Codex?▼

Yes. It ships as a plugin with a SKILL.md that teaches coding agents when and how to use each command.

How fast is Scalex on large codebases?▼

It indexes around 17,000 files in a few seconds on first run, then uses git-based caching so warm queries return in under a second.
