Hexana is a binary inspector for WebAssembly modules and components, shipping as an IntelliJ-platform plugin and a VS Code extension built from a single Kotlin parser. It observes binary structure rather than transforming code, so the row claims focus on what is decoded.

Approved under the existing Tools category per the discussion in #543 (tomayac, tlively, dschuff). Three rows are encoded as [true, note] to flag specific gaps:

  • componentModel: 10/13 top-level sections decoded; canon, value, and component-level start are stubs; embedded component-type custom section not yet extracted.
  • memory64: 64-bit limit flags and memidx-carrying memory ops are decoded; not separately validated against the rest of the proposal.
  • multiValue: type-index multi-value blocks decoded; empty block-type 0x40 is misdecoded as a reference type (known bug).
  • threads: full 0xFE atomic opcode family; shared-memory flag 0x03 parsed; open-shared flag 0x02 not yet parsed.

Closes #543.

Hi, just wanted to randomly chime in, I wonder if we could find ways to further compress this png file from 130 kb (which is 3x larger than the current largest logo1), for example by using https://squoosh.app to reduce the palette and/or using webp. Lots of logos on this page and they kind of add up bit by bit over time 😂

We do have scripts/optimize-svgs.js to reduce the SVGs a bit, but it can't cover raster logos

Footnotes

  1. chicory.svg is 42 kb gzipped
