I've used emacs in various configurations over the years, but the one aspect I couldn't find a good proxy for is relative directory logic.

My goal is to use evil-mode + web-mode. I'm not interested in doing everything possible in emacs. I just want really good vim emulation and syntax highlighting. I think emacs does a better job of these things at the cost of added complexity and trying to parse emacs-lisp.

In Sublime Text you can "open a folder" and then when you go to open a file it assumes it's contained within the "current" directory.

In VIM I can "cd" to a directory and all all files I open are relative to that directory i.e. "e foo/bar.py" in the command prompt assumes current_directory/foo/bar.py.

tl;dr Is there a simple way to "cd" to a folder, so that opening and searching for files to open are relative to that folder? I've tried dired & projectile but wonder if there's a much simpler option that more closely maps to the UX of vim.

There is command cd: M-x cd (or bind it to a key).

There is also Dired: C-x d, then C-h m. Or C-h r g dired, which takes you to node Dired of the Emacs manual.

Both of those should help you. See also variable default-directory, using C-h v.

C-h f cd tells you this:

cd is an interactive compiled Lisp function in files.el.

(cd DIR)

Make DIR become the current buffer’s default directory.

If your environment includes a CDPATH variable, try each one of that list of directories (separated by occurrences of path-separator) when resolving a relative directory name. The path separator is colon in GNU and GNU-like systems.
