doesn't run it
python.set {cell?, code, output?: object|value} makes the cell (the
active cell by default) a Python cell, keeping its style and taking a
formula and its spill away. `output` is the return type Microsoft
documents for PY(): an Excel value (the default) or a Python object;
without it a Python cell keeps the one it had. The code must fit in
Excel's 8,192-character formula once written as PY(...), quotes doubled
and literals joined, so the command checks the encoded formula rather
than a character count. A table's header row refuses Python (it holds
the column's name, as Excel keeps formulas out of headers), and a locked
cell on a protected sheet refuses it through the usual protection check.
Nothing runs Python here. Unchanged code keeps its cached result and
value; new or changed code shows #BLOCKED!. One undo step takes the cell
back.
Sheet::clear_spill removes the spilled values inside a range with work
bounded by the values stored, not by the range's size.
In the interface, F2, a double click or the formula bar on a Python cell
edits its code, and a changed text is committed through python.set,
which keeps the return type; through cell.set it would have replaced the
Python cell with an ordinary cell holding the code as text. Typing over
a Python cell replaces it, as typing over a formula does, and committing
the code unchanged writes nothing. Deleting all the code clears the
cell through cell.set, as an empty entry clears any other cell; code
of spaces is still code.
Tests: the code and return type in cell.get, #BLOCKED! for new code,
cached results kept for unchanged code, the active-cell default, undo,
refused params (missing or non-text code, a bad cell, a bad return
type), the encoded limit at 8,079 and 8,080 characters and with doubled
quotes, a table header, a protected sheet, and a formula's spill taken
away. A UI test edits a Python cell's code with F2 and Enter, commits it
unchanged, and types over it; another clears a Python cell by deleting
all its code, keeps code of spaces, and undoes the clearing.
Cell gains `py: Option<Arc<PyCode>>`, read with a serde default and not
written for ordinary cells, so older native files load and ordinary
cells serialize as before. PyCode holds the code, the return type (an
Excel value or a Python object), the last result (value, type name,
preview, whether it converted to cells) and a stale flag for manual
calculation. The cell's `value` stays the cached result, so formulas,
display and saving read a Python cell like any other. is_blank,
CellStore::has and input_text (which returns the code) take the code
into account; Cell::has_content and clear_content cover value, formula
and code together.
The model reads and writes the PY function's syntax as Microsoft
documents it, PY("chunk"&"chunk",0|1), with string literals of at most
255 characters and the return type 0 for an Excel value, 1 for a Python
object. The reader takes the `_xlfn._xlws.` prefix (and `_xlfn.` or
`_xlws.` alone, in any letter case); to_file_formula writes it. (An xlsx
file keeps the code in its Python part instead; the xlsx commit adds
it.) The size limit is Excel's 8,192 characters for that formula, not a
count of code characters: doubled quotes and the "&" between literals
count, so code with many quotes fits in fewer characters (8,079
characters of plain code fit exactly). The model also finds the
xl("...") literals in code, skipping comments and other strings; a plain
literal may escape a quote or a backslash. A rewritten reference that
holds the literal's quote (a sheet name that needs quotes, 'Q4
2026'!B2) takes the other quote as the literal's delimiter, or an
escaped quote when it holds both, so it never ends the string early.
Edits: cell.set over a Python cell, Clear Contents, Clear All and the
cells a merge empties remove the code; Clear Formats keeps it. Copy and
paste (All, Formulas), Fill, sort, cut-move, sheet copy and undo carry
it; a cut to another sheet first qualifies its xl() references with the
source sheet, as a moved formula's references are, so they keep
reading the same cells. Paste Values and Paste Link do not carry it,
and paste operations do not combine numbers with a Python cell. Fill
copies Python cells instead of extending them as a series. cell.set
with =PY(...) is refused with a message that points to python.set, and
Text to Columns keeps a piece that reads as =PY(...) as text instead of
clearing it. Goal Seek refuses a Python cell as its changing cell, and
Solver as a variable cell, as both refuse formulas: the number written
there would replace the code. The sheet-protection check compares the
code, so a locked Python cell cannot be changed. cell.get reports
{python: code, output, typeName, preview, stale}.
The xl() literals follow reference-moving edits: rewrite_all_formulas
(row and column insert and delete, cell insert and delete, cut-move),
sheet rename and sheet delete adjust each literal like a formula
reference, and replace it only when it changed.
Errors: CellError gains Python, Busy, Timeout and Blocked, and ALL has
14 entries, so the lexer reads them as literals. ERROR.TYPE gives 11 for
#BLOCKED!, the number Excel returns. Microsoft documents no ERROR.TYPE
number for #PYTHON!, #BUSY! or #TIMEOUT!; they take 19, 20 and 21, after
the numbers Excel is known to use. The xlsx writer caches the four as
#VALUE!, as it already does #SPILL! and #CALC!, because they are not
error codes of the file format.
Tests cover the =PY refusal, removal by entry and clearing, undo, copy,
paste values, fill and sort, xl() rewrites through row insert, sheet
rename (also to names that need quotes, with one quote and with both),
cut-move (also to another sheet) and column delete, Goal Seek and
Solver refusing Python cells, Text to Columns keeping a =PY piece,
native JSON round trips, the new errors, the prefixes, escaped quotes in
literals, and the encoded size limit at 8,192 characters exactly and
with doubled quotes.
craft-update, craft-window, craft-ui and craft-print all come from one craft-libs revision, the
head of storytold/craft-libs#340 on the aiongg fork, until #340 merges.
Scripts can't run the View tab's window commands (Switch Windows, New Window, Hide, Unhide):
they change the active workbook, as window.* steps do. The Switch Windows button names its
accessibility role with egui::Role (egui 0.37).
Extract helpers from auto_sum (selection and single-cell guess), update_cursor
(drag, hover, freeze, and header-edge cursors) and read_styles (dxf reader).
No behaviour change.
* feat: startup update prompt modal and direct self-updating
The update flow (check at start or on request, the startup prompt, the self-update worker) is craft-update's Updater; the app only supplies the suite, its close path and its status message. An install holds back while the workbook is unsaved.
Ref: storytold/craft-libs#319
* build: refresh the lock
* build: pin craft-update to craft-libs main (db19c37)
* fix(updates): address review feedback
Wake the UI when a manual check is queued from a menu callback; the update prompt owns the keyboard while it is open (LightCraft); Download opens through the desktop URL hook (FilmCraft); the Help menu dispatches through menus::invoke (FigCraft); print jobs and comment drafts hold an install back (WordCraft); Check for Updates is a registered command (GridCraft); an install holds back while documents are unsaved.
* fix(updates): add Check for Updates… to the native macOS Help menu
* E37: migrate GridCraft to egui 0.37
Pin the reviewed fork and shared dependencies, adapt input and rendering to the
new frame lifecycle, and preserve bounded capture handling and font notices.
Add representative accessibility checks and meaningful control labels.
Validation: full repository CI passed all ten stages, with 2,249 tests passed,
zero failed and one existing timing test ignored. Native workflows and paired
performance qualification remain documented separately.
* egui037: record final published pins and local qualification
* M0.37: fix RTL clipping and preserve screenshot budgets
* test: share migrated GridCraft UI harness setup
* egui037: document migrated UI and regression contracts
* egui-037: align popup test fonts and avoid redundant tooltip probes
* Sonar: explicit imports, fn paths for closures, extract helpers for cognitive complexity

* Fix imports
* Fix serde imports
* Fix engine imports
* Fix clippy gate and a type error from the explicit-import change
Remove the unused imports the review flagged (cf.rs, pivot.rs, tables.rs, cmd/sheet.rs) so clippy -D warnings passes, and point the backstage parent-folder lookup at Path::to_str, which the fn-path rewrite had broken.

* Apply rustfmt to the explicit-import cleanup so the fmt gate passes
* Share the per-directory font path expansion in theme.rs
The candidate font lists repeated the same loop over the Linux font
directories in every role. A single helper expands them in the same order,
so the lookup order is unchanged and the duplicated blocks go away.

* Build the light and dark UI palettes from one table in theme.rs
Tokens::light() and Tokens::dark() listed the same 40 colour fields in the
same order, so every change had to be made twice. A single palette
constructor takes the mode and picks each colour's value, so each field is
written once and both modes keep their exact colours.

* Share the Noto CJK font list between the CJK script lists in theme.rs
The Japanese, Simplified and Korean lists each repeated the same loop over
the Linux CJK directories with a different locale file name. One helper
builds that loop, and each list keeps its own face index, so the lookup
order is unchanged.

* Share Linux Noto directory list across Thai and Hebrew font lookups
Removes the duplicated directory arrays flagged by SonarCloud new-code duplication.
* Reuse in_dirs for Thai and Hebrew Noto font candidates
Removes the remaining duplicated per-directory loops flagged by SonarCloud.
* Share one font-list builder for the Thai and Hebrew faces
The two per-script functions repeated the same Windows, macOS, Linux and
variable-font setup. A single script_fonts helper now builds both lists,
keeping the candidate order unchanged, which clears the Sonar duplication gate.

Sheet1!A1:SHEET1!B2 is a range whose second end repeats the sheet, as
Sheet1!A1:Sheet1!B2 is: the check uses same_name, Excel's case-insensitive
name comparison.

AutoSum over any selection of more than one cell wrote a total under each column, so a row
selected (B2:E2) got four one-cell totals in row 3 instead of =SUM(B2:E2) in F2.
As Excel does, totals now go in the selection's empty last row or column, and otherwise past
it:
- a single row: its total in its last cell when that is empty, else just to its right;
- a block whose last column is empty: each row's total there; whose last row is empty: each
column's; both: both, and the block's total in the corner;
- otherwise totals under each column, as before.
A whole-row selection still stops at the data's last column, and all totals are one undo step.
Tests: autosum_over_a_row_totals_it_to_the_right,
autosum_over_a_whole_row_totals_it_after_the_data and
autosum_fills_a_selections_empty_last_column_and_row; each fails without the change.
