SCL aus parametrisierten Templates: Golden-Files, Render-Kontext, Pilot 1Sep1Swi
Schritte 1-3 aus doc/SCL_Templates.md (neu: Konzept, Wertklassen je Zeile, Namensregeln, Tests, Migrationsplan, Vertrag fuer den CSV->SCL-Workflow). - Golden-Files (tests/test_scl_skeleton_golden.py, tests/fixtures/scl/): komplette FB_Main-Ausgabe von mubea und HundM05 byte-genau festgeschrieben, Zeitstempel maskiert; gewollte Aenderung per SKEL_UPDATE_GOLDEN=1 - lib/scl_context.py (neu): alles, was scl_skeleton aus der TRO-JSON ableitet (Reihenfolge, Separator-/Weichen-/Scanner-Bloecke, Staubereiche, Ziellisten, Namen) als pydantic-Kontext SclFile/SclTro; Namen als SclName (Wert + todo-Merker) als Andockstelle fuer die Namensregeln (Schritt 4). scl_skeleton schreibt nur noch Text; Ausgabe byte-identisch (Golden-Files, zusaetzlich dematic/showroom mit und ohne --start alt/neu verglichen) - lib/scl_templates/ (neu, Jinja2): _macros.scl.j2 + Pilot FB_ILS_MTRO_1Sep1Swi.scl.j2 nach der realen Aufrufstelle TRO107 (PriorityManagerDir2, stInSenJam<n>, xInCarouselRun1, xInRelease TRUE, Separatorzeiten 100/50 ms). Ortsgebundene Zeilen als Vorschlag umgesetzt, jede offene Stelle mit TODO(E-Planung) - Bestaetigung durch SPS steht aus - scl_skeleton: --templates [DIR] (opt-in, ohne Schalter Ausgabe unveraendert), --strict (Exit 1 ohne SCL, wenn ein FB-Typ kein Template hat); Kopf und Zusammenfassung nennen Template-/generische Typen; Templatefehler (StrictUndefined) -> Exit 1 ohne SCL - tests/test_scl_templates.py: Rundlauf Template mit Referenzwerten == Referenz-REGION (normalisiert); jede Platzhalterzeile traegt den TODO-Marker - requirements.txt: jinja2 >= 3.1 (bestehende .venv: pip install -r requirements.txt) - Doku: SCL_Templates.md, Python_Scripts.md §5b, Commandlines.md §2.5, CLAUDE.md Befunde: xInCarouselRun1 laesst sich nicht aus der TRO-JSON ableiten (Kanten- art "umlauf" kommt praktisch nicht vor) -> immer als TODO; nTo1Destinations ist in der Referenz 3 bei 2 Abgaengen (zaehlt evtl. Ziele) -> "pruefen". Mit --templates nur die 1Sep1Swi-REGIONs (+ Kopf) anders als generisch; 32 Tests gruen. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

@@ -473,6 +473,33 @@ so `--start` is no longer needed once the export contains a station. In the
|
||||
jam-area comments they are marked "(Station, kein TRO)", and an exit station
|
||||
shows up as a destination in the per-switch lists.
|
||||
|
||||
**Internal structure.** `scl_skeleton.py` works in two stages:
|
||||
`lib/scl_context.py` derives everything from the TRO-JSON into a render context
|
||||
(`build_context` → `SclFile` / `SclTro`: flow order, separator/switch/scanner
|
||||
blocks, jam entries/exits, destination lists, names), and `scl_skeleton.py` only
|
||||
turns that context into text (`render_context`). Every name or address is an
|
||||
`SclName` (value + `todo` flag); today all of them are placeholders with
|
||||
`todo=True`. This split prepares the move to parameterised templates and
|
||||
per-project naming rules described in [`SCL_Templates.md`](SCL_Templates.md).
|
||||
|
||||
**Templates (opt-in, `--templates [DIR]`).** With this switch every TRO whose FB
|
||||
has a template in `lib/scl_templates/<fbType>.scl.j2` (Jinja2) is rendered from
|
||||
it; the others keep the generic text above. The header and the console summary
|
||||
name which FB types came from a template. Today only the pilot
|
||||
`FB_ILS_MTRO_1Sep1Swi` exists — it follows the real call site of TRO107 line for
|
||||
line (priority manager `Dir2`, `stInSenJam<n>`, `xInCarouselRun1`, reference
|
||||
times 100/50 ms), and every value that is still open carries
|
||||
`TODO(E-Planung)`. `--strict` stops (exit `1`, no SCL) if any FB type has no
|
||||
template. Without `--templates` the output is unchanged.
|
||||
|
||||
Tests: `tests/test_scl_context.py` (the derivations one by one),
|
||||
`tests/test_scl_templates.py` (each template rendered with the real values of
|
||||
its reference call site must equal that call site, comments and whitespace
|
||||
ignored) and `tests/test_scl_skeleton_golden.py` (the whole output of mubea and
|
||||
HundM05 byte for byte against `tests/fixtures/scl/*_FB_Main.scl` and
|
||||
`*_FB_Main_templates.scl`, timestamp masked; an intended change is written
|
||||
back with `SKEL_UPDATE_GOLDEN=1`).
