ispyisail	0920e82188	Add geometry editing, undo integration, and navigation to scripting ... Extends the scripting surface from the previous commit with exactly the three things explicitly scoped out there, per follow-up direction: editing geometry, undo integration, and driving the GUI -- the last one narrowed to select/zoom/message after discussion, since "invoke any menu action by name" would let a script trigger a modal QDialog::exec() with nobody there to dismiss it, the same hang class investigated for bugtracker #882. ## New capabilities - addElement/setElementPosition/moveElement/deleteElement, through the same undo commands the GUI itself uses: AddGraphicsObjectCommand (the same one drag-from-collection-panel placement uses), QPropertyUndoCommand on the standard `pos` property, and DeleteQGraphicsItemCommand (refuses a non-deletable terminal, same as the Delete key). - undo/redo/canUndo/canRedo against the project's real QUndoStack -- the same one QETDiagramEditor's Ctrl+Z is wired to via undo_group.activeStack(), not a parallel mechanism. - selectElement/deselectAll (scene state, no view required -- works headless), zoomFit/zoomToContent/zoomReset (need the active DiagramView, so false headless where there is nothing to zoom), and showMessage (a modal QET::QetMessageBox::information -- safe headless because non-interactive mode is already on for the whole process before any script runs). ## Two real bugs caught by testing this, not assumed away 1. save() was still going through the same reopen-from-disk path as every export method: it opened a *second*, unmodified copy of the project from its file on disk and rewrote that. addElement() and friends operate on the live in-memory project, so nothing they did ever reached the saved file -- an element counted correctly in memory and then silently vanished from the output. Fixed by having save() write m_project->toXml() directly, the only method that touches the live instance rather than a fresh copy of the file. 2. A script calling setElementPosition() then moveElement() on the same element produced a saved position that didn't match either call, and undo/redo didn't step through them independently. Traced to QPropertyUndoCommand::mergeWith() (pre-existing, not new): consecutive commands on the same object+property merge when their text() also matches, and both calls build the identical "Déplacer %1" text for a given element -- exactly the same collapsing dragging an item repeatedly gets. Not a bug in the new code; a wrong assumption in the first test. Re-verified against the correct, merge-aware expectation: add -> merged move -> undo (back to first position) -> undo (element removed) -> redo (element back) -> redo (merged move reapplied) landed at the exact predicted final position, read back from the saved XML. ## Verified Qt6, build clean from a fresh reconfigure, ctest 6/6. - Headless: addElement returns a real uuid and the count updates; select/set-position/move all report correctly; the merge-aware undo/redo/save round trip above, confirmed against the saved file's actual XML, not just in-memory counters. - Corpus: the existing read-model smoke script re-run against all 24 shipped example projects on the fixed binary, 0 failures. - zoomFit correctly returns false headless (no view to act on), confirming the "narrowed GUI-driving" scope holds in code, not just in the doc comment. - GUI: running the add-only script via "Exécuter un script..." marked the project [modifié] in the title bar, the same change-tracking path a manual edit goes through -- consistent with the undo command actually being pushed onto the project's real stack rather than some side channel invisible to the rest of the application.

ispyisail	eba258f6cd	Add JavaScript scripting: --run and "Run Script..." (bugtracker #162) ... Following up on my own comments there: a deliberately small, mostly read-only scripting surface, exposed to scripts as a single global `qet` object (QetScriptApi) built on QJSEngine rather than an embedded Python interpreter -- no new toolchain to package (QJSEngine ships in every Qt SDK QET already targets, via the Qml module), no GIL, no version pinning, automatic reflection of the QObject-derived core classes' own methods with no hand-written binding layer. ## What a script can do - Read the model: project title, file path, folio count/titles, element/conductor counts per folio. - Trigger the same operations the --export-* CLI flags already do (pdf/png/svg/cables/wires/bom/wiring/nets/links/info), plus set-titleblock and save -- thin wrappers around CLIExport::run(), reusing its already-tested logic rather than duplicating it. Deliberately NOT in this version: creating or editing diagram geometry, undo integration, driving the GUI. All explicitly out of scope per the discussion on #162. ## Two entry points, both built and tested - `qelectrotech --run script.js project.qet` -- headless/CI. - Projet > "Exécuter un script..." -- an interactive macro against the currently open project. Export/save calls act on the project's file on disk (see QetScriptApi's class comment for why), so unsaved GUI edits aren't visible to the script; save first if that matters. ## Optional dependency, not a hard requirement Qt::Qml is probed the same way QtPdf already is in this codebase: QUIET, non-fatal, behind a QET_HAS_SCRIPTING compile definition. A build without it compiles and links identically; the CLI flag and menu action are simply absent (main.cpp) or compile to a clear "not available" stderr message rather than silently disappearing (qetscripting.cpp), matching the existing QtPdf pattern rather than introducing a new one. One real bug caught building this, not assumed away: my first pass conditionally excluded the new source files from QET_SRC_FILES behind `if(QET_HAS_SCRIPTING)` inside qet_compilation_vars.cmake -- but that file is included before QET_HAS_SCRIPTING is set in the top-level CMakeLists.txt, so the variable didn't exist yet at that point and the files were silently never compiled, only caught by an undefined-symbol link error. Fixed by following the QtPdf file's own precedent: compile the files unconditionally, guard their Qt::Qml-dependent content internally instead. ## Verified Qt6, build clean, ctest 6/6. - Headless: a script reading project/folio/element/conductor counts, calling exportInfo() and exportPdf() against a real project -- correct JSON, a real single-page PDF confirmed with `file`. Error paths: a thrown script exception reports file:line:message and exit 1; missing script/project arguments exit 2 (matching CLIExport's own usage-error convention); a missing project file is reported and does not hang. - Corpus: the same read-model script run against all 24 shipped example projects, 0 failures. - GUI: "Exécuter un script..." opens a real file dialog filtered to *.js, running the picked script against the live open project produced the exact expected JSON export file, and the application was still fully responsive afterward.
