Module formula 

The Excel formula language: tokenizer, parser, syntax tree, printer (A1 and R1C1) and reference adjustment for copy/fill and structural edits.

Modules

adjust

Reference adjustment: copying formulas, inserting/deleting rows and columns, moving cells, renaming and deleting sheets.

ast

Formula syntax tree.

lexer

Tokenizer for Excel formulas (A1 style, canonical or selected UI separators).

parser

Pratt parser: tokens → Expr.

printer

Expr → formula text (without =), A1 or R1C1.

Enums

FormulaLocale

Formula-entry syntax selected by the interface language. Other interface languages currently use the canonical English function table until a translation table is supplied.

Functions

fold_name

The case-folded form of a name: two names are same_name when their folded forms are equal.

parse_input

Parses UI input using the selected function table and separators. Existing names and LET/LAMBDA bindings take precedence over aliases. File and API syntax uses crate::formula::parse.

print_input

Prints canonical expressions for editing. Name collisions retain the canonical spelling so displaying then committing a formula never changes a defined-name reference.

same_name

Whether two LET/LAMBDA names are the same: case-insensitive in any script, as in Excel (dług = DŁUG, ß = ẞ). Close to Unicode’s default case folding: lower case, plus the folds lower-casing misses for letters a name may hold (ß/ẞ -> ss, ſ -> s, ς -> σ). Dotless ı stays distinct from i, as outside Turkic languages.
