Release 0.3 and Linux Kernel Demo

Hello dear subscriber,

Codevyr 0.3.0 is finally ready 🎉

Summary of changes:

  1. Type system. Indexers now also track files, types, macros, and more -- not just functions.
  2. Nested symbols. The UI renders containment hierarchies: functions inside files, types inside modules.
  3. C language support. New indexer for C codebases (with partial C++ and CUDA/GPU support).
  4. UI. Save queries, search nodes in the graph (Ctrl+F), export graphs as PNG, see which query statement produced each node.
  5. Performance. A series of backend optimizations to support indexing large codebases — including the Linux kernel.
  6. Query language. Some syntax changes to askl in this release.

The query language is still a bit limiting for more complex use cases, so the next release will focus on usability and expressiveness.

The demo now includes some of my favorite C projects. The Linux kernel is one of them. Take a look :)

And if you want to index your own projects, you can run Codevyr locally.

I would appreciate any suggestions or feedback.

Try the demo queries: Demo (Go) and Demo (C).
