Core::EditorManager::instance()->currentEditor()
(->file()->fileName(), that includes the path)

Nice.

Ah, why "most local"?
/me already sees the emails that these variables should also be used  
here-and-there.

You might be interested to have a look at Core::VariableManager, which  
is a class that was originally started to provide such kind of  
variable replacement.

It's more or less a hash of (variablename, value) pairs plus a method  
"resolve" which performs (very simple) variable expansion. It's  
currently not used anywhere, and the design might be a bit too simple  
for some things, but it might be a good place to start from. Would be  
nice to somehow avoid myString.replace("${CURRENT_EDITOR}",  
editorManager->currentEditor()) all over the place ;) . And it would  
make it possible to do the variable expansion in a more intelligent  
way at all places where it's used then.

BTW, you can find us on irc://irc.freenode.org/#qt-creator :)

Best regards, Eike
