Formatting library and CLI for Fallout SSL, WeiDU BAF/D/TP2/TRA, Fallout MSG, Infinity Engine 2DA, and Fallout scripts.lst files.

pnpm add @bgforge/format

Requires Node 20 or newer.

Pure-string formatters take a raw file's text and return formatted text plus an optional warning:

import { readFileSync, writeFileSync } from "node:fs";
import { formatTra, formatMsg, format2da, formatScriptsLst } from "@bgforge/format";

const raw = readFileSync("dialog.tra", "utf-8");
const result = formatTra(raw);
writeFileSync("dialog.tra", result.text);
if (result.warning) console.warn(result.warning);

The same pattern applies to formatMsg, format2da, and formatScriptsLst.

Tree-based formatters (formatFalloutSsl, formatWeiduBaf, formatWeiduD, formatWeiduTp2) take a parsed tree-sitter root node plus formatting options; see the source for the exact signatures.

Other helpers cover comment stripping (stripCommentsWeidu, stripCommentsFalloutSsl, ...), formatting validation (validateFormatting), tokenisation (tokenizeWeidu), and editorconfig discovery (getEditorconfigSettings).

fgfmt <file|dir> [--save] [--check] [--save-and-check] [-r] [-q] [--jobs <n>]

• --save - write formatted output back to file(s)
• --check - exit 1 if any file is not already formatted
• --save-and-check - save and verify idempotency in one pass
• -r - recurse into directories
• -q - quiet mode (suppress summary)
• --jobs <n> - process directory files with n parallel workers (output order matches the sequential walk; with --check, all files are checked before the exit code instead of stopping at the first mismatch)
