stringx

The stringx namespace — 1 function.

globals/stringx/scanNumbers

stringx.scanNumbers(s: string, pos: number?) -> ({ number }, number)

Read the run of numbers starting at pos — separated by commas and/or whitespace — and report where the run ended.

The run stops at the first character that neither continues a number nor separates two of them (], }, a quote, a letter), and nextPos is that character's index, so the caller's own parser resumes exactly there. A token that is not a valid number also ends the run, with nextPos left ON it rather than past it, so nothing is skipped without the caller seeing it.

Parameters

• s string — The text to read.
• pos number (optional) — 1-based index to start at. Defaults to 1.

Returns ({ number }, number) — The numbers found, and the 1-based position just past them.

-- A JSON array of numbers, in one crossing instead of one per token.
local values, nextPos = stringx.scanNumbers(payload, afterBracket)
-- A whitespace-separated block (OBJ, PLY, a matrix dump).
local m = stringx.scanNumbers("1 0 0 0  0 1 0 0", 1)
