feat: Execute element — inline Structured Text in Ladder and FBD - #1098
MatthewReed303 wants to merge 8 commits into
Conversation
Adds an "Execute" (ST Block) element that holds a raw ST snippet inside an LD rung or an FBD canvas, edited in place or in an expand modal, with live strucpp diagnostics and inline debug value badges. Emission is EN-gated with ENO passthrough, and PLCopen import/export follows what CODESYS writes: <block typeName="EXECUTE"> carrying its source in an <addData>. Also fixes, found while testing: - CODESYS LD export threw on a contact or coil fed from a block-shaped source with no variant - imported rungs reached the editor grouped by XML element type, so inserting an element wired it to the wrong predecessor - imported rails were named so the rung layout could not find them - imported rungs kept the exporter's cumulative Y offset - "Export to CODESYS XML" produced old-editor XML - the debugger's range selector painted through open modals
- LD: an Execute box with no power input ran every scan; it now warns and emits nothing. FBD keeps bare emission for an unwired EN. - Import: key the Execute snippet map on POU name and @localid — localId is unique only within a POU, so one POU's snippet overwrote another's. - Import: keep an empty rung (two rails wired to each other) instead of dropping it as a rail-only component; it vanished on every reload. - Import: translate an Execute output's empty @formalParameter to OUT the way parseBlockXml does, so the ENO wire resolves to a handle that exists. - LSP: encode each illegal character in executeStScopeId — a-b and a/b shared one shell name, so two open snippets declared the same symbol. - Debug: guard computeRungDebugStates against cycles, which overflowed the stack, and guard the Execute .code read against absent node data. - Debug: build the IL decorations URI with Uri.parse, matching the model @monaco-editor/react creates. - ST field: commit the buffered draft when the field is deselected without a pointerdown outside it. - fbd-xml: narrow soleOutputHandleId's array and handle at runtime. Adds a regression test for each.

Return TRUE from an unwired FBD Execute ENO.
emitExecuteNode treats an unwired FBD EN as always true. This branch instead calls visitCoilPassthrough, which returns undefined when there is no incoming path. A downstream coil or output therefore receives no power and can be omitted.
Return TRUE_NODE when FBD passthrough has no upstream path. Add a regression test for Execute -> output-variable with unwired EN.

Execute documents are not re-published after a library cache change.
forceResync calls projectSync.forceResync() only. The comment on Line 97 states that the worker does not re-run analysis on stlib cache mutations, so documents keep their cached analysisResult. Execute snippets are now separate worker documents. After a library is enabled or disabled, an Execute snippet that references a library symbol keeps its stale diagnostics until its text changes.
attachExecuteSync already supports a forced re-publish through publish(..., force), but ExecuteSyncHandle exposes only dispose(). Add a forceResync() to the handle that re-publishes every tracked URI with force = true, and call it here.

Encode uppercase characters in executeStScopeId.
The graphical builders preserve the supplied node ID, and the PLCopen importer accepts raw @localId values.

Rescan debug positions when the editor remounts.
When a web tab switch changes editorModelPath, the URI guard in useStDebugDecorations can cache null while editorRef still points to the previous model. The new PrimitiveEditor mount increments editorInstanceId, but the hook receives only modelVersion. If the debugger variable keys stay the same, the new tab can remain without inline values. Increment modelVersion on mount, or pass the mount generation to the scanner so it reads the new model. React retains a memoized result until a dependency changes. (react.dev)

Review
Every comment from #1058 has been addressed — nine correctness fixes and
one runtime-narrowing change, each with a regression test that fails
without it. Details are in the follow-up commit.
One suggestion was not taken: replacing
useOpenPLCStore.getState()inthe Execute node's event callbacks with selector hooks. Every other
graphical node reads the store the same way in its handlers (
coil.tsxdoes the identical
{ project, ladderFlows }read on blur). Convertingwould subscribe every Execute box to
project.data.pousandladderFlows, re-rendering all of them on any rung edit, and wouldreintroduce the stale-closure read the current code exists to avoid.
