- Vergleichsoperatoren (= <> > < >= <=) unterscheiden jetzt Text- von
Zahlenvergleich statt jede Seite zwangsweise durch toNumber() zu
schicken (=A1="Nord" gab vorher #VALUE! statt 1); ermöglicht
Text-Kriterien in selbstgebauten COUNTIF/SUMIF/AVERAGEIF-Funktionen
(neue README-Sektion "SUMIF/COUNTIF/AVERAGEIF nachbauen").
- Neuer &-Operator (Excel-Präzedenz zwischen Vergleich und +/-) plus
CONCAT/CONCATENATE als Funktions-Äquivalent.
- Benannte Bereiche: neuer Toolbar-Button "🏷" verwaltet dokumentweite
Namen für eine feste Zelle/einen festen Bereich (z. B. Umsatz_Q1statt
Umsatz!B2:B6), unqualifiziert in jeder Top-Level-Formel nutzbar.
Live gegen die Tabellen-ID aufgelöst (übersteht Tabellen-Umbenennung),
bewusst nicht innerhalb einer benutzerdefinierten Funktion selbst
nutzbar (Aufrufer können sie aber als Argument übergeben).
- Nebenbei: COUNT2s Autovervollständigungs-Hint korrigiert (zeigte
"COUNT(...)" statt "COUNT2(...)").
374 Tests, vue-tsc/eslint/build sauber, Playwright-live-verifiziert.

A custom function body could previously only be a single expression --
no way to iterate over a range's elements to build something like
PRODUCT (multiply every cell together), since none of the built-ins
(SUM/AVG/MIN/MAX/COUNT) do that and a body can only compose existing
functions, not define a new reduction. This adds a second body kind,
'block': a sequence of `name = expression` assignments and
`FOR var IN source DO name = expression` loops, ending in
`RETURN expression`. Flat scope -- every introduced name stays visible
for the rest of the body, including after its own loop, holding its
last iteration's value.
No runtime loop in the evaluator: a loop's source size is already known
once the caller's real argument is substituted in, so
userFunctions.ts's new compileBlock() unrolls every FOR loop into a
single nested expression (a left fold) at the same parse-time inlining
point Phase 1 already used -- the result is exactly the same shape of
static AST as any other inlined function call, so evaluator.ts and
graph.ts need no changes, dependency edges on every unrolled cell are
picked up automatically, and a bounded MAX_UNROLL_STEPS (10,000) keeps
it crash/hang-free. parser.ts's parseFunctionBlock() parses the new
grammar (a purely additive EQUALS lexer token; FOR/IN/DO/RETURN are
plain case-matched IDENTs, not new reserved tokens) into a BlockNode
kept outside the existing Node union, so no existing switch needs a
new case.
Store: CustomFunction/FunctionDef gain `kind: 'expression' | 'block'`
(defaulted for every function saved before this existed, including via
JSON import). validateCustomFunction validates the new grammar's local/
loop-variable names the same way as parameters (not cell-shaped, no
reserved words, no shadowing a parameter -- but reusing the same local
across statements, the accumulator pattern, is correctly not a
collision) and that every FOR source is structurally a parameter, cell,
or range. UI: a "𝑓 Funktionen" form toggle between "Einfache Formel"
and "Mit Schleife", with its own placeholder/hint (a PRODUCT example)
and a small badge on block-kind rows in the list.
237 tests passing (34 new), vue-tsc/eslint/build clean. Verified live
in the running app: defined PRODUCT via the loop UI, called
=PRODUCT(Umsatz!B2:E6), confirmed the correct value and recalculation
on a change to a cell inside the range, and an inline rejection for an
invalid FOR source at save time.

Document-wide, named formula functions (e.g. MARGE(revenue; cost) =
(revenue - cost) / revenue) callable from any cell like a built-in
(=MARGE(Umsatz!B2; Umsatz!C2)). Created, edited and deleted only through
a new "𝑓 Funktionen" toolbar button -> modal (list + shared edit form),
never via JSON handedit.
Engine: a call is inlined into the caller's AST at parse time
(src/engine/userFunctions.ts's expandUserFunctions), so evaluator.ts and
graph.ts need no changes -- dependencies on cells referenced only inside
a function body (not in the call) are picked up for free. parser.ts
gains an optional paramNames argument to parseFormula() producing a new
ParamNode leaf, used only when parsing a function body.
Store: addCustomFunction/updateCustomFunction/deleteCustomFunction with
inline (not toast) validation -- name/parameter shape, no collision with
a built-in or another function, the body parses, and a definition-time
cycle check across the whole call graph. Renaming/deleting a function
mirrors table rename/delete: existing calls are not rewritten, they
become #NAME? on the next rebuild. Fully undo/redo-able and part of the
JSON document (customFunctions: [], migrated for v1 and older v2 docs).
178 tests passing (32 new), vue-tsc and eslint clean. Manually verified
end-to-end in the running app via Playwright: define/call/recalculate,
rename -> #NAME?, a closing cycle rejected inline at save, undo restores
the function library.
