how to set custom variable when open a file type?

[bangedorrunt]

@yqrashawn, in the example section same key in different mode, you say that we can set custom variable when open a file type using karabiner cli, but i'm wondering how we can do that? could you elaborate?

Seems the link is broken in the doc. I never tried it on my own. But karabiner's cli has the arg --set-variables which can

Set variables which are used in complex modifications.

So I suppose user can, for example, set the editing_file_cpp variable by invoking some editor functionality to execute shell script when opening a .cpp file. Combine with a current application condition user can define rules for editing cpp file in each application.

thank you, that's what i thought. i think whenever a project is opened, we can run a simple task that execute karabiner_cli to set the variable.
