Overview ¶

Package formula reads the formula being typed in the UI: the reference F4 cycles through absolute markers, and the word and function call around the caret that formula assistance follows. It works on the entry's runes alone.

Index ¶

func ArgPart(parts []string, arg int, variadic bool) int
func CycleRef(buf []rune, pos int) ([]rune, int, bool)
func SplitArgs(args string) []string

Functions ¶

func ArgPart ¶

func ArgPart(parts []string, arg int, variadic bool) int

ArgPart maps an argument index to the part of the signature that describes it: a repeating part like "[value2, ...]" covers every argument from its position on. It returns -1 past the last argument.

func CycleRef ¶

func CycleRef(buf []rune, pos int) ([]rune, int, bool)

CycleRef finds the reference (or range) at or just before pos in a formula and returns the text with its absolute markers cycled, and the caret moved to the reference's end.

func SplitArgs ¶

func SplitArgs(args string) []string

SplitArgs splits a signature's arguments at the top-level commas, so "[value2, ...]" stays one part.

Types ¶

type Caret ¶

type Caret struct {
	Word      string
	WordStart int
	Fn        string // e.g. "SUM", or "" outside any function's parentheses
	Arg       int    // index of the argument the caret is in
}

Caret describes the formula text before the caret: the word being typed, if it may be a function, name or sheet, and the innermost function call the caret is in. A sheet name being typed in quotes is a word starting with the quote, e.g. "'Q3 p".

func ScanCaret ¶

func ScanCaret(buf []rune, pos int) Caret

ScanCaret reads a formula up to pos the way the lexer does: strings are skipped, parentheses nest, and commas or semicolons at the innermost level separate arguments.
