CSE 333 Vim cheet Sheet

This page is designed to help you get Vim to help you. Vim has a long history and a massive number of commands, key board shortcuts, and more. This guide brings to you the most commonly used and most useful commands for writing C/C++ code in vim.

If you’ve taken CSE 391, then you may remember that there is a file called .bashrc which lives in your home directory and contains commands that are run whenever you log in. The .vimrc file is similar to this, except it contains vim commands that will be run whenever you open a file in vim. These commands can do things like change the color theme, turn on line numbers and enable syntax highlighting. If you run the command below on attu or the CSE vm, you can download a .vimrc file that has been created by the TAs that should make your vim experience a lot better. You can read the comments in the file to see exactly what each command is doing. Additionally, this command will place another configuration file in the folder ~/.vim/after/ftplugin/c.vim which contains commands that will only be run when you open a C or C++ file.

Run this command to install the .vimrc

curl -o ~/.vimrc https://courses.cs.washington.edu/courses/cse333/21wi/resources/vimrc.txt && curl --create-dirs -o ~/.vim/after/ftplugin/c.vim https://courses.cs.washington.edu/courses/cse333/21wi/resources/c_vim.txt

What's included in the .vimrc:

1. Press F9 to run make (you can also just do :make). Then, you can run :copen to see the output alongside your code. Vim will even take you to the lines that have compiler problems.
2. Open a window with the man page using the command :Man <page number> <function>
3. Adds a ruler at 80 characters so you can avoid those pesky linter complaints.
4. Highlights whitespace at the end of lines.
5. Turns on line numbers by default.
6. Automatically turns tabs into spaces and automatically indents the proper amount after hitting enter.
7. Sets the color theme to ‘ron’. Instructions for changing this are in the .vimrc file.
