Opening an .xlsm and saving it silently stripped xl/vbaProject.bin, turning a
macro-enabled workbook into a macro-free one — data loss for anyone whose work
depends on macros. GridCraft still does not run VBA, but it now carries the
project through unchanged.
- model: `Workbook.vba_project: Option<Vec<u8>>` (base64 in JSON via a new
`b64::opt` helper). `None` = no macros.
- xlsx read: capture the `vbaProject` relationship's bytes instead of warning
and dropping them; warn that macros are kept but not executed.
- xlsx write: when present, emit `xl/vbaProject.bin` byte-identical, add the
`.../relationships/vbaProject` relationship, switch the main part to the
macro-enabled content type (`...sheet.macroEnabled.main+xml`) and add the
`application/vnd.ms-office.vbaProject` override.
- engine: `view.macros` lists the preserved project alongside GridCraft's own
scripts (`{"kind":"vba","executed":false}`), so callers can see it is there.
- ROADMAP: scope now "preserve, don't execute" (was "out of scope").
Tests: round-trip byte-identical blob + correct content types/relationship;
capture from a foreign-produced .xlsm; a macro-free workbook stays clean.
Local clippy (1.96) flags pre-existing code that an older toolchain accepted;
these lints fire on clean main and block `cargo xtask ci`. All rewrites are
behavior-preserving:
- core/date.rs, numfmt/render.rs, functions/math.rs, functions/stat.rs:
`!x.is_finite() || x < a || x >= b` -> `!(a..b).contains(&x)` (Range::contains
is false for NaN/inf, matching the existing is_finite guard).
- functions/util.rs: `!(A && !B)` -> `!A || B`.
- engine/cmd/file.rs: drop a dead `.filter(|| true)`.
- ui-egui/grid.rs: `find(|| true)` was always the first table (use `.first()`);
`wrap || Justify || (nl && wrap)` -> `wrap || Justify`.
- ui-egui/formula_bar.rs: `tab || (enter && false)` -> `tab`.
- engine/cmd/spelling.rs: split the wasm/non-wasm dictionary init so the
non-wasm `mut` no longer warns under wasm check.
- ui-egui: title bar with QAT, full ribbon (Home/Insert/Draw/Page Layout/Formulas/Data/
Review/View/Automate + Table/Chart Design), formula bar with Name Box, virtualised grid
(frozen panes, overflow, borders, CF data bars/scales/icons, tables, sparklines, filter
buttons, charts/pictures/shapes), in-cell editor with point mode, reference colouring,
autocomplete and argument hints, sheet tabs, status bar, dialogs, control channel
- apps/sheetcraft: desktop app (control server, file dialogs, prefs, drag & drop)
- chart: toolkit-free chart layout/rendering for 25 chart kinds + sparklines + rasteriser
- mcp + sheetcraft-cli: MCP server (headless or bridged) and CLI (info/convert/eval/cat/run/mcp)
- xtask (ci/layers/assets/wasm/version/parity), release workflows, packaging, placeholder icon
- automatic row heights
