Global configuration file

[mpeterv]

There should be a way to put some configuration into a file in predetermined location and have it apply when project-specific config isn't found.

Some points:

• Why not use global config even when local config is found, as a foundation? The problem is that then presence of local config doesn't ensure consistent behaviour for several users as well as it does now (currently it's enough to set 'std' option or use same Lua version).
• What should be the name of the file? '.luacheckrc' most likely, like local config.
• Where should the file be located? It has to depend on OS, need to check what's typically used on Windows.
• Should there be options to disable or alter path of global config? An option to disable it should be enough.

I would like to standarize the configuration file used in .luacheckrc and possibly merge it with atom-autocomplete-lua .luacompleterc

@mpeterv do you have any interest on this? What about you @dapetcu21?

This file would (for example) be called .luarc and its format would be JSON or similar (both understood by Lua and JS), and would be an alternative to both .luacheckrc and .luacompleterc. Note that the intention is not to replace the current formats but to provide one which can be understood by both Luacheck and Autocomplete

[mpeterv]

@positive07 that could be interesting, but please open a separate issue for it.

[pablomayobre]

If you are fine with discussing in this repo I'll do it, otherwise I think we can discuss it privately (I still need to see if @dapetcu21 is interested too)

Feel free to delete both this comments

[dapetcu21]

@positive07 Could be interesting, but it's a pretty big undertaking, both in terms of coordination effort and actual development.

[pablomayobre]

All right lets discuss this over at pablomayobre/.luarc#1

Feel free to clear this conversation from here

Implemented on master branch, global config location is %USERPROFILE%\Local Settings\Application Data\Luacheck\Config\.luacheckrc on Windows and $XDG_CONFIG_HOME/luacheck/.luacheckrc or ~/.config/luacheck/.luacheckrc on other systems (by default). Need to check if there are better options for Windows and Mac.

[pablomayobre]

A few options, the install folder, next to luajit... Also why Luacheck\Config in Windows and not simply Luacheck?

[mpeterv]

Yes, just Luacheck for Windows is good enough. I don't want to use intallation directory of Lua/LuaRocks or Luacheck itself, it should be a single location. Otherwise user would have to copy files around if using several installations (e,g. with hererocks).

[pablomayobre]

Understood, sounds great then!

Is a new release comming?

[mpeterv]

Yes, I plan to make a new release tomorrow

[mpeterv]

I'm uncertain if on Mac config should be under ~/.config like on Linux or under ~/Library/Application Support as recommended by Mac app programming guide.

[mpeterv]

After reading microsoft/vscode#3884 looks like ~/Library/Application Support is preferred.
