this is a follow-up of another thread. I am trying to implement a plugin which provides basic path/file autocompletion. For the time being, the autocompletion should simply suggest the files and folders relative to the file location. Hence, given this structure:
If the file mycustomfile is opened, the autocompletion should suggest "dir1". If one enters "dir1/", it should suggest "dir2" etc. Is there any standard CompletionContributor which provides such a functionality or do I have to code that by hand?
