KiCad pairs project files purely by basename + same directory: a folder
holding `Foo.kicad_pro`, `Foo.kicad_sch`, `Foo.kicad_pcb` opens as one
project on double-click of the .kicad_pro, with cross-tool navigation
(open footprint from schematic etc) wired up automatically.
- pro_writer.write_kicad_pro() renders the minimal KiCad 8 JSON we
need: meta.filename pinning the basename, sheets=[[<root_uuid>,
""]] binding the schematic root, and stub blocks for board /
schematic / net_settings / erc that KiCad expects to find on the
first GUI load.
- root_sch_writer.write_root_sheet() now accepts an optional
root_uuid so the caller can pass the same uuid into the .kicad_pro
and .kicad_sch (the binding fails silently with mismatched ids).
- CLI gains `--all`: groups SCH/PCB docs by their META.board uuid
(1:1 in EPRO2), strips SCH-/PCB- editor prefixes from titles to
derive a shared project basename, and emits one directory per
BOARD with paired files. BOARDs whose SCH is DELETE_DOC (LCD-BD on
ESP-VoCat) still get a .kicad_pro with sheets:[] + .kicad_pcb so
pcbnew opens cleanly.
ESP-VoCat smoke: 6 boards → 6 project dirs, all pairs validated by
kicad-cli sch erc / pcb export svg. The CoreBoard pro/sch/pcb trio
shares root uuid 366d3e53...c2fccbe4330b end-to-end.
68 → 71 unit tests pass.

"""CLI: convert EPRO2 SCH_PAGE docs to KiCad ``.kicad_sch`` files.
|
|
|
|
Usage:
|
|
uv run python -m tools.epro2.kicad <project_dir> --doc <sch_uuid> --out <dir>
|
|
uv run python -m tools.epro2.kicad <project_dir> --all-sch --out <dir>
|
|
uv run python -m tools.epro2.kicad <project_dir> --all-sch --flat --out <dir>
|
|
|
|
By default ``--all-sch`` produces a hierarchical project: pages are grouped
|
|
by their parent SCH (``META.schematic``) and each group gets a directory
|
|
with a root ``.kicad_sch`` plus its child pages. ``kicad-cli sch erc`` on
|
|
the root then resolves cross-page nets via ``(global_label)``. Pass
|
|
``--flat`` to fall back to one file per page in a single directory (the
|
|
old behaviour, still useful when you only care about a single page).
