Nim Upstream Skill
Ground-truth reference for the Nim language and standard library used by Maestro's frontend/.
Authoritative source
- Repo:
git@github.com:nim-lang/Nim.git — https://github.com/nim-lang/Nim
- Use it (via
github_repo / fetch_webpage) to confirm std/* module APIs (json, strutils,
os, streams, unittest), pragma behavior, and --mm:orc memory semantics.
When to apply
- Verifying a Nim
std API signature or a language construct (templates, macros, proc/func).
- Questions about ORC memory management, value vs ref types, or
defer lifecycle.
- Formatting/build questions:
nph, nimble, Nim ≥ 2.0 features.
How to use it in Maestro
- Prefer local conventions first: the
tatui-frontend skill and .github/instructions/nim-frontend.
- The frontend targets Nim ≥ 2.0 with
--mm:orc; ignore pre-2.0 or GC-specific upstream guidance.
- Cite exact upstream paths/permalinks when relying on upstream behavior.
Guardrails
- The TUI is a thin renderer: no orchestration logic in Nim; the draw is a pure function of state.
- Frontend Nim only consumes Tatui widgets; it does not reimplement TUI primitives.
