François 300e871aed Help screen, explore→set-connector-type Enter, settype UI polish.
- New `screen_help.cpp` (`screen_idx = 6`). Left column: menu of 13
  topics (Overview, Dashboard, Console, Palette, Explore,
  Connect/plug, set-connector-type, Signal types, NC pins, Analyze,
  Scripting, Save/restore, Quitting). Centre column: paragraphs of
  the focused topic, word-wrapped via `paragraph()` and scrollable.
  Right column: standard help panel.
- `help` bare → opens the screen; `help <name>` keeps the existing
  textual command-help behaviour for scripts.
- Dashboard `[h]` shortcut opens the screen, and the dashboard help
  panel (both the loaded and the no-system branch) lists it.
- Console: title gets the standard breadcrumb (`essim → console —
  type commands, read textual output`). Module/connection counters
  moved off (they live on the dashboard now).
- Explore Enter on a part jumps to `set-connector-type` with the
  exact-match index pre-computed in the filtered list (avoids the
  substring-match collision where `J20` would land on the wrong
  row when J200/J21 also matched).
- set-connector-type screen: bind `focused_entry` to `selected` on
  both menus so the cursor `>` tracks the selected row when state
  is pre-seeded from outside. Right column drops its strict
  `size(WIDTH, EQUAL, 40)` in favour of `flex`, and the `new type`
  input uses `xflex` so it actually stretches across the column.
- Esc on `set-connector-type` honours `screen_back_idx` — when
  entered via Enter on a part in `explore`, Esc returns to explore;
  otherwise it returns to the dashboard like every other screen.
  Standalone command entries explicitly reset the back-link.
- Net-member rows in the explore detail pane carry a
  `module\tsignal` payload so Enter opens the popup scoped to the
  peer module rather than mis-firing on the locally selected one.
  Same scheme for local-pin rows.

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
  • 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 with plantuml classes.puml for 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

  • doxybook2 is not packaged in Arch / AUR and gets stale upstream.
  • moxygen drags 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.
  • @throws for 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.
