- `essim --commands-md [file]` instantiates the Tui, calls
`Tui::DumpCommandsMd(ostream&)` which iterates the live registry and
emits Markdown grouped by interactive/other, then exits. Single
source of truth: a new `CommandSpec` field surfaces automatically.
- CMake `doc` target now `DEPENDS essim` and chains:
doxygen → gen_api_md.py → doc/api/
essim --commands-md → doc/user/commands.md
- `doc/user/` adds:
- index.md (hand-written) — first session, interactive-screen
conventions, save/restore/replay overview.
- scripting.md (hand-written) — `set`/`$var` expansion semantics,
`source` event-paced execution, script-save denylist, worked
example pointing at test/system.essim.
- commands.md (auto-generated, regenerated by the `doc` target).
- Top-level README refocused on quick start; pointers to the new
doc tree (user/, api/, DESIGN.md) instead of an inline command table.
- doc/README.md and DESIGN.md document the two-pipeline doc workflow.
- `test/system.essim` and user docs anonymised: bkp → backplane,
vdn1/2/3 → payload1/2/3, cb3p → payload4, bpb/cob/ssu →
peripheral1/2/3; netlist file names + variable names + paths all
replaced with generic equivalents.

essim documentation
Auto-generated API reference and high-level design notes for the essim system digital twin.
Layout
user/— user-facing docs (hand-written intro/tutorial- auto-generated command reference). Start at
user/index.md.
- auto-generated command reference). Start at
api/— developer-facing API reference (Doxygen XML → custom Markdown emitter). Browse classes and files directly in gitea's Markdown renderer. Top page:api/index.md.../DESIGN.md— implementation notes: domain conventions, TUI flow, gotchas. Hand-maintained.classes.puml— PlantUML class diagram for the domain model. Render withplantuml classes.pumlfor a PNG/SVG.Doxyfile.in/gen_api_md.py— the toolchain (templated Doxygen config + custom XML→Markdown emitter).
Regenerating the API reference
The Markdown tree under doc/api/ is committed so it's readable directly
on gitea. After substantive code changes, regenerate it:
# 1. Tooling (once): Doxygen, plus a Python 3 interpreter (already on Arch).
pacman -S doxygen
# 2. Configure once (or after editing doc/Doxyfile.in):
cmake -S . -B build
# 3. Regenerate:
cmake --build build --target doc
# 4. Review and commit the updated doc/api/ tree:
git add doc/api/
git status doc/api/
Pipeline:
src/**/*.{hpp,cpp} ──┐
README.md ─┼─► doxygen ─► build/doc/xml/ ─► gen_api_md.py ─► doc/api/
DESIGN.md ─┘ (Doxyfile.in)
(built essim) ────────► essim --commands-md ──────────────────────────► doc/user/commands.md
doc/user/index.md and doc/user/scripting.md are hand-written; only
doc/user/commands.md is regenerated. The doc target depends on the
essim binary so a stale build is rebuilt before the dump is taken.
If either Doxygen or Python 3 is missing at CMake-configure time the
doc target is silently disabled (the regular build still works) and a
status line is emitted in the CMake log telling you which one to install.
Why a custom emitter rather than doxybook2 / moxygen
doxybook2is not packaged in Arch / AUR and gets stale upstream.moxygendrags Node into a pure-C++ project.- The emitter is one Python file (
gen_api_md.py, ~330 lines) with zero external dependencies — easy to read, easy to tweak, robust to Doxygen version changes (the XML schema is stable).
Tailor the output by editing gen_api_md.py directly: add columns to
the class table, change the source-link format, group sections
differently, etc.
Comment style
The codebase uses standard Doxygen markers:
///for single-line briefs./** … */for multi-line blocks.@param,@return,@brief(or@short) tags inside blocks.@throwsfor exceptions a function may raise.
JAVADOC_AUTOBRIEF = YES is set so the first sentence of a multi-line
comment counts as the brief description without needing an explicit
@brief tag.
