tools/tb2err: Formats Lua traceback in errors.err format
Manually opening to the files and line numbers from a Lua traceback is
tedious. This tool converts tracebacks into a format that many compilers
and such tools use, which is also compatible with Vim (and possibly
other editors).
Thus if someone sends you a pastebin link with a traceback, a command
like the following gets you right to the relevant lines:
curl paste.example/abc123.txt | tb2err > errors.err; vim -q
