Re: [Pydev-code] asynchonous output on console

[Jonah G. <jo...@ki...>]

Hi Fabio,

Thank you for the feedback. I have had a look at the code you
mentioned and I think it is not the best first project. I have some
enhancements for the command completion within the interactive console
that I will complete first. That should make me more familiar with the
code so I can better implement the asynchronous features.

BTW The features I am looking into adding are:
* a preference to hide completions that start with _, unless the
underscore is typed. This is so that private members are hidden by
default.
* add completions of file system path names so that commands like
open(...) are easier to type.

Thank you,
Jonah
