Update abaplint.json, set folder

[larshp]

I've set the configuration to https://github.com/abaplint/abaplint/blob/main/docs/getting_started.md

when its green, then additional rules can be enabled

Thanks, I've haven't finished the customization of it, in fact I was wondering if with this very bad coding I have inside, is it possible still. As I don't want to make non-backward compatible changes in the names of the parameters and methods... but let me spend some time on this.

its very strict in the default setup, with everything enabled, even some stuff that I'd typically not use

it will get there, just need a few things fixed, like abaplint/abaplint#3388

https://abaplint.app/stats/fidley/falv/disabled_rules will update tomorrow, so you can take a look at which rules you'd like enabled

Thanks, I'll take a look tomorrow then
