[Pydev-code] PyVocabulary & new developers

[Aleks T. <a...@to...>]

Hi everyone,
we've got Dana & Bill as the official developers! Feel free to=20
check in.

On Friday I realized that I needed to fully understand bdb.py &=20
pdb.py, and that required lots of code navigation. Being bored=20
with trying to decipher what debugger APIs are, I took a look on=20
what it would take to implement cmd-click hyperlinks in pydev. It=20
is one my favorite features in the Java editor, and something I=20
could really use right now.

Java editor implements it in about 600 lines of code inside a=20
MouseListener. I think I can lift most of it.

The other requirement for context navigation is a database of=20
defined symbols inside a file being edited. Right now I am=20
working on implementing this.  Here are my design notes:

### DESIGN NOTES
To implement navigation/completion.
- Each editor needs a vocabulary. The vocabulary is hierarchical=20
in structure, and has items:
Top-level (file vocabulary) has:
  classes
  functions
  globals?
Class vocabulary has:
  documentation string
  classes
  methods (functions)
  instance variables (inferred from self.)
Method/function vocabulary has:
  documentation string
  locals
  classes
  functions

Each definition in the vocabulary describes:
- where is it defined (file, char span)
- character range where it is applicable

Vocabulary usage:
Find an innermost vocabulary containing current selection.
Then quiz it for whatever is needed

Questions:
  can vocabularies be overlapping? That would make things hard.
###

Dana, this sounds like it overlaps with your work a bit. Any=20
suggestions about what I am doing so that we do not conflict?

 text, and some time later begin typing 'to', it offers a suggestion of '=
toto'. You can then hit TAB or ENTER and it deposits the text for you?

I know how to do that and can finish it after we get further on with the =
autocompletion work.
