How much Poka reads

B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.

Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-nim/src/main.rs (302 lines) and plugin.json in full. The crate has no unit tests and no tests/samples.rs, and the corpus has no .nim, .nims and .nimble sample, so the tier rests on reading the code. Covers .nim, .nims and .nimble. The output is a metadata card of counts found by matching text line by line: imports, from-imports, includes, proc, template, macro and iterator, converter, method and func, types, const, var and let sections, pragmas, when blocks, doc comments and line counts. Judgement: B4, because the structure is summarised but the source itself is never shown.

What Poka does not read

  • The source text is not shown: the card carries only counts and a few sample names, with no code view or highlighting
  • Constructs are found by matching text line by line, not by parsing, so multi-line declarations, nested or indented definitions and keywords inside strings or comments can be miscounted
  • Counts of named items stop where their name list is capped (imports at 32, types at 32), so a larger file under-reports them
  • Files over 32 MiB are cut to the first 32 MiB (the card says so)
  • Text that is not UTF-8 is decoded with replacement characters; no other encoding is tried
  • Nimble package fields (version, author, requires) are not read as such
