use xdg base directory specification about arbtt

Yeah, any of these sound reasonable.

Although probably the configuration should go into $XDG_CONFIG_HOME and the captured log into $XDG_DATA_HOME or $XDG_STATE_HOME. This probably rules out the second plan.

The first plan would require moving different files to different locations, and then it’s unclear what to do with files left over in ~/.arbtt.

Sounds like the last plan is the most reasonable.

That’s reasonable, but would require a migration plan for existing installations, such as moving ~/.arbtt, or using it if it exists. And documentation.

Since the practical value is not too big, this is not high priority for me at the moment.

Possible migration plans:

• Detect existing .arbtt folders and move them to the new location
• Same as above, but additionally put a symlink on the old location (in case 3rd party tools are hard-coding the path)
• Honor the XDG specification but look for .arbtt first. That way, only new installations will be affected. (Optionally emit a warning so that users know they may want to move the directory manually.)
