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-pli/src/main.rs (279 lines) and plugin.json in full. The crate has no unit tests and no tests/samples.rs, and the corpus has no .pli and .pl1 sample, so the tier rests on reading the code. Covers .pli and .pl1. The output is a metadata card of counts found by matching text line by line: procedures, OPTIONS(MAIN), DECLARE, ON-units, DO, END and IF, CALL, RETURN and GOTO, GET and PUT LIST, READ and WRITE, ALLOCATE, FREE and SIGNAL, FORMAT, %INCLUDE 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 (procedures 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
