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-hbs/src/main.rs (264 lines) and plugin.json in full. The crate has no unit tests and no tests/samples.rs, and the corpus has no .hbs, .handlebars and .mustache sample, so the tier rests on reading the code. Covers .hbs, .handlebars and .mustache. The output is a metadata card of counts found by matching text line by line: the detected flavour (Handlebars or Mustache), expressions, substitutions and triple-brace substitutions, block openers and closers, partials, comments, decorators, sub-expressions, chained helpers and the most used helpers and variables. 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 (sample helpers at 8), 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
  • The template is not rendered and partials are not resolved
  • The literal text and HTML around the placeholders is not shown
