new idea: high light local variables in a function body

[ollydbg]

I see that we have a function:

Code

void CodeCompletion::UpdateEditorSyntax(cbEditor* ed)

which give a set of tokens(keywords) as member variables to scintilla control, so that it can highlight them, by

Code

    ed->GetControl()->SetKeyWords(3, keywords);
    ed->GetControl()->Colourise(0, -1);

So, if we put a mouse in a function body, and let our parser parse the function body, and give scintilla control all the local variable tokens, and finally we can only highlight them inside the function body by

Code

    ed->GetControl()->SetKeyWords(3, local_variables_list);
    ed->GetControl()->Colourise(begin_of_function_body, end_of_function_body);

EDIT: some old similar discussion: CC based semantic highlight

No you can't, because this is global keyword set.

This example code will break it easily:

Code

int myGlobal=5;

int myFunc() {
    int myGlobal=7;
    
    ... do something with the myGlobal...
}

This feature needs to be done with a custom lexer or modifications to scintilla.

Indeed, I agree with you, so it is hard to implement this idea.
