Having a cursor follow along in the file is just one part of a visual debugger. Seeing the call stack and being able to move up/down, the ability to see scope variables, the ability to enter console commands are all essential. Lack of these is why I stopped using SublimePdb, instead switching to pudb: https://pypi.python.org/pypi/pudb
I highly recommend it as the lightest weight interactive debugger out there for Python.
It wouldn't do step debugging or breakpoints, but at least for scripting and even simple c programs it would work well.

Well, then again, I've never seen an IDE that comes close to ST/Vim/etc in their lightness, speed of opening, editing, switching files, and pleasantness of the core editing experience, much less one without a heavy beast of a UI. Or one that you can setup exactly as you want, as heavy or as light as you like, plugin by plugin, without all kinds of crap builtin.
When it's all said and done, all that matters is that you're able to get the work done. Take vim, for example. You can quite often use CLI tools to get the work done due to vim's integration into the surrounding ecosystem, and this includes things such as debuggers.
For a language like C#, you're never going to find as integrated an experience as you will with Visual Studio. It's just not going to happen.
But for everything else, you absolutely can be as productive in something like vim, the workflow is just different.
My issue is with the acknowledgment by the author that the standard for "IDE" includes debugging capabilities and then goes on to provide a plugin that provides follow-along only via running GDB, which would need to be configured (I assume, since the author does not specify) the normal ways.
If you want to argue UNIX is the IDE I can get behind that definition, but the debugger is absolutely not integrated into Sublime (or Vim or Atom or N++ or ...) in any meaningful way.
The point is to get work done, not do it all in a single window. you talked about "capability" as if because someone uses an external debugger you can't debug effectively or very well when using something like vim.
It's a flawed definition of effective.
When you use something like vim, the entire ecosystem is your IDE.
If the entire ecosystem is your IDE, you're not "Turning Sublime Text into a Lightweight Python IDE".
I don't know how else to phrase this to make it clear that I'm not attacking, denigrating, claiming inferior, etc., composite workflows like vim + GDB. But if you get to an article that says XYZ is now your IDE, and it offers a piss-poor debugging experience unless you leave XYZ, then that article is not turning XYZ into an IDE.
> There is no plugin for SublimeText that supports this. But there is a Python package you can install into the virtualenv for each of your projects that does it.
This drives me batty whenever I see "turn XYZ into an IDE for (foo)." The author of this post at least lists debugger integration as part of the IDE experience, but comparing against actual full fledged commercial / non-plugin-composite IDEs? I haven't seen one article for turning Atom/ST/Vim/etc into an "IDE" that comes close (edit: that is, close to a reasonable debugging experience, in an integrated way) capability-wise.
There's nothing wrong with taking that approach, but if you need to shim on GDB and use a plugin to just follow along in source (forget setting watches, gutter-click breakpoints, conditional breakpoints, etc., from Sublime Text), that's pretty definitively not integrated into Sublime.
