Find the closest known function name(s) to an unknown token.

Uses generalised edit distance (utils::adist) over the worksheet-function registry (LEGACY_WORKSHEET ∪ XLFN ∪ XLWS). XLM macro names are excluded from suggestions since user typos in worksheet contexts are almost never typos of XLM names.

Usage

.spell_suggest(fn, n = 3L, max_dist = 3L)

Arguments

fn

Unknown function name (uppercase).

n

Maximum number of suggestions to return (default 3).

max_dist

Maximum edit distance to consider a useful suggestion (default 3).

Value

Character vector of suggestions, possibly empty.

Details

Returns up to n suggestions, or character(0) if the closest match is more than max_dist edits away.
