AFAIK kdevelop support this.

Pydev uses pylint interactively, must have saved me hours by flagging up
(potential) problems up as I type.

There has been a recent thread on some emacs group about this. Dunno how
far it has gone wrt Python support, but the following mode appeared in
MELPA archives in the last couple of days:

One of my long-term goals for Idle is an extension that would run
user-installed code analyzers over the contents of an edit window, with
the output sent to an OutputWindow. Using the contents of the latter to
mark things in the editor window is an interesting idea. That is already
done for SyntaxErrors and traceback file:line references.

I think it would take some time to get used to, and I don't think it
would be the only way I'd like to view my program.

I think an interactive pylint (or pyflakes or frosty) type capability
would be useful, highlighting a subset of the messages it produces,
like variables which were assigned but never used, or using undefined
variables. It might be best supported by actually running the checker
in the background, then using its messages to direct where to
highlight suspect bits of code.

Highlighting program variables instead of keywords? topic

My son sent me a link to an essay about highlighting program data instead
of keywords:

https://medium.com/p/3a6db2743a1e/

I think this might have value, especially if to could bounce back and forth
between both schemes. Is anyone aware of tools like this for Python? Bonus
points for pointers to an Emacs implementation.

Thanks,

What it is doing is color coding user-supplied identifiers, with
different color for each one. I found that confusing to read. The only
use I can see for this is to track the usage of a particular name, but
that would be better done by just highlighting one name at a time.

In SciTE, I can put the cursor on a word and hit Ctrl-F3 to find other
instances of that word. If that's not enough, following it up with
Ctrl-Home, F3 will find the first instance of it, and if the program
follows the Define-Before-Use principle, that'll be the definition.
That's usually enough.

That said, though, I grew up without syntax highlighting of any sort,
and didn't think it particularly important; but now that I have
editors with all those sorts of features, I do find them handy. So
it's possible that a system like this would be of value if once the
programmer gets used to it.
