No, you still need ctags to jump to sources outside of your current file. But within the same file, it works fine without it. C doesn't have a defined directory structure, and a lot of the source/header files you'd use are stored in places like /usr/lib and such.

Note that cscope is significantly better than ctags and also built into vim.

Yeah, but that is the thing, an IDE works with more than one file.

  I feel like you're taking my words in bad faith. Vim works perfectly fine with multiple files out of the box, it just wants a tag file for jumping between multiple files and letting autocomplete work with those tags. This is hardly unique to vim (and emacs) - you can't work on a project in IntelliJ without first setting up a workspace and letting IntelliJ index all those files. The only difference is how the index is generated. Oh, and `:help cscope` (again, thanks aidenn0). In vim >=9.0 a tagging tool is now incorporated into the base vim install.

    Nope, just making the point that vim has lots of things to catch up with a proper C IDE in a default install. ctags was just the first example of many things I can refer to. For example any basic C IDE on a default install is expected to have debugging integration, project management, among other stuff.

      I'm so confused. Vim has ctags, and it works, across multiple files. Granted I don't think vim is an IDE, but you'd demonstrate that better by pointing to the IDE stuff it doesn't do (like debugging, I think, but I debug with printf and only rarely fire up gdb so for all I know it does support it).

        Op thinks it is one, > Vim defaults to being a C IDE, no plugins required

        Right, but ctags isn't the reason it's not. Ctags just works and goes substantially above and beyond what you'd expect of "Just a text editor".
