How do I use the --globals option? about luacheck HOT 3 CLOSED

It looks like the way argparse parses command-line arguments is not obvious, unfortunately... In hindsight it seems a bad idea, but it is supposed that options like --globals, --ignore and --only are used after positional arguments(file names), because these options accept multiple arguments. I.e. when luacheck --globals xml myfile.lua is passed, it considers both xml and myfile.lua globals and then panics because there were no file names passed.

The correct way would be

luacheck myfile.lua --globals inspect xml

I will think about changing this and will definitely expand docs in the next release.

Hi, thanks for answering this, it is clear what was happening now.

In case this helps you, I think most of my confusion came from the command in-line help:

$ luacheck --help
Usage: luacheck [-g] [-r] [-u] [-a] [-v] [--globals [<global>] ...]
       [-c] [-e] [--ignore <var> [<var>] ...]
       [--only <var> [<var>] ...] [-l <limit>] [-q] [-h]
       <file> [<file>] ...

Notice how --globals appears before the files, not after. This is probably more an issue with argsparse than with luacheck though.

I see, thanks for pointing this out, will be fixed soon.
