[Geany-devel] tagmanager related questions

[Константин Лосев]

I used zend engine tokenizer from php.
now i am talking only about autocomplete_scope (editor.c)
for example i type "$hello->" after that there is searching algorythm, it worked in such way:
1) found tag.
2) get it varType
3) search tag using varType
4) search scoped members of tag with varType
5) show user autocompletion window.

so if varType is not set, then there no be any scoped members.
