Named parameters (docs/named_parameters_design.md, stages 3-4):
- ParameterTable (src/scene/named_parameters.rs): a document-wide table of
named formulas, each resolved through a shared expression evaluator with
cross-parameter references, cycle detection, and division-by-zero/parse
error reporting. SketchConstraint::driving_param becomes DrivingValue
(Literal | Named) instead of a bare f64, resolved at solve time by
sketch_solve::build_constraint via Scene::named_parameters.
- Persistence (src/scene/named_parameters_persist.rs): same lazy XRecord
model sketch_persist.rs already established, synced around open/save.
Bumps the sketch-constraint XRecord's own format version (1 -> 2) since
DrivingValue's shape doesn't line up with a version-1 blob's bytes.
- PARAMETERS command and its editor (src/ui/window/named_parameters.rs):
add/remove/edit rows, live validation, duplicate-name detection: Apply
defines the table and re-solves every constraint scope with a
named-parameter-driven constraint (command_driver.rs). Distance/Angle
constraint prompts (modules/draw/constrain/value.rs) now accept either a
literal or an existing parameter's name, mirroring how the constraint's
own value prompt already worked.
- Undo scope-down carried over from this project's own established pattern
(constraint-system stage 9): the geometry an Apply moves is one undo
step, but the parameter table edit itself has no undo entry yet — a
documented follow-up, not a silent gap.
UI scale setting (src/app/settings.rs, app/mod.rs, ui/window/options.rs):
a whole-interface scale percentage (50-200%), wired directly into iced's
own per-window scale_factor hook rather than per-panel font-size
plumbing, so it applies immediately to every panel, dialog, and the
ribbon at once. Persisted alongside the existing lineweight-display-scale
setting.
OPTIONS/OP command dispatch (app/commands/view.rs, app/commands/mod.rs):
OPTIONS was registered for autocomplete but had no dispatch arm — the
Start-tab welcome screen's own button was the only way to reach it.
Found live-testing the UI-scale setting, unrelated to that feature
itself. "OP" is AutoCAD's own short alias.
help/: a new self-contained static user-help manual (manual.md as the
authored source, tools/build_help.py splits it into the committed static
HTML pages plus search index) — not yet wired into the application.
64 new/updated tests across the named-parameters and constraint-prompt
changes.
