v6.55.1 (2026-05-10)

Bug Fixes

  • fix(plugin): eliminate SWIG reads + restore plot dir + auto-save after Gerbers (#255) (#258)

  • refactor(plugin): eliminate SWIG reads from archive template expansion (#255)

Replace board.GetProject() / board.GetTitleBlock() SWIG calls with
file-based reads in both plugin.py and dialog.py.

Background: The dirty flag (*) appearing on ActionPlugin toolbar invocation
is a KiCad 10 framework behavior — the C++ ActionPlugin dispatch marks the
board modified before Run() is called, regardless of plugin code.
Confirmed: Fabrication Toolkit exhibits identical behavior.
This cannot be fixed from the plugin side.

What we CAN do: avoid adding unnecessary SWIG reads on top of the
framework-set dirty flag, which improves correctness and removes coupling
to the live board object for read-only metadata.

Changes:

  • plugin._expand_archive_template() → _expand_archive_template_from_file()
    Reads title block metadata from .kicad_pcb via jBOM S-expression parser.
    No pcbnew SWIG calls. Fallback to PCB filename stem.

  • dialog.init: cache TitleBlockMetadata from disk at init time
    (self._pcb_title_meta) via create_metadata(), zero SWIG calls.

  • dialog._on_archive_template_changed(): use self._pcb_title_meta
    instead of board.GetProject() / board.GetTitleBlock(). Standard
    title block tokens (${TITLE}, ${REVISION}, ${DATE}, ${COMPANY},
    ${CURRENT_DATE}) are supported; custom .kicad_pro project variables
    are not (acceptable trade-off documented in docstring).

No behavior change for users: archive name expansion works identically
for all standard templates.

  • fix(plugin): restore plot output directory after Gerber generation (#255)

Root cause of dirty flag after Generate: PLOT_CONTROLLER.SetOutputDirectory()
writes into the board's persisted plot settings, marking it modified. After
generation completes the stored path points at a deleted temp directory, which
also confuses KiCad's built-in plot dialog.

Fix: snapshot GetOutputDirectory() before plotting and restore it in a
finally block after ClosePlot(). The board settings are left in their
pre-generation state; KiCad's dirty tracking sees no net change to the
output directory and should not mark the board modified.

Note: Interactive HTML BOM plugin does not cause dirty because it never
calls SetOutputDirectory(). FT causes dirty because it does not restore
the setting.

  • fix(plugin): auto-save board after Gerber generation (#255)

PLOT_CONTROLLER setters (SetOutputDirectory etc.) modify the board's
persisted plot settings, dirtying it. Saving after Gerbers keeps the
board file in sync with what was generated, consistent with the zone-fill
auto-save rationale. Whether this clears the UI title-bar asterisk
depends on KiCad's frame notification path from a background thread;
if it does not, the dirty flag on Generate is accepted as a known
limitation per #255 investigation.
