3 sources> I am always amazed when some more experienced programmers than me spend valuable time grepping files and using GDB on the command line.
I don't know about Vim, but Emacs works very well as a visual debugger, for quite a couple of languages. It looks like this for C, for example: http://www.inet.net.nz/~nickrob/gdb-ui.png (it's Emacs debugging itself in this screenshot).
In general both Vim and Emacs can become IDEs that are on par with other offerings. For Python development, I worked with Komodo, PyCharm, Vim and Emacs. With jedi[1] both editors get context sensitive autocompletion (for some strange reason called "IntelliSense" or something by some) and "find definition", "rename identifier" etc. With Rope, they both get nice refactoring support. With Magit/Fugitive, you get the prettiest and most functional GUI for git. With Speedbar/

TagBar[2] you get classes outline. With yasnippet/vim-snipmate you get configurable, programmable snippets/templates. And so on and on - all that on top of largely superior editing model that is being developed and improved for 30 years.
I worked with Komodo, PyCharm and a couple of other IDEs, then switched to Vim and I didn't feel that I'm missing something. Then I switched to Emacs because I wanted an editor that I could easily customize as much as I'd like, and VimL just didn't cut it. There is nothing comparable to Emacs in terms of extensibility, LightTable and Atom may get there with time, but I suspect it will take quite a few years. No other IDE even tries to approach this level of extensibility and customizability.

Ask HN: How does code completion (as in IDEs) work on a technical level?
Conceptually, I understand the parts, but I'm having trouble translating that to working code. I've been doing some research and came across Jedi (https://github.com/davidhalter/jedi), which is an autocomplete library for Python.
Is there some guide somewhere that walks through the process of building something like Jedi for some other language (even an imaginary one)?
While it's tangential to this particular discussion, my goal (eventually) is to learn what I need to know to be able to build something like Jedi for PHP. There's only a handful of options for PHP code completion, and none of them provide the level of intelligence of a proprietary IDE like PhpStorm. That needs to change, IMO.
