Vim

vim is a modal editor (improving on vi). It can run without graphics, is ubiquitous, powerful, and efficient but is an acquired skill.

• MIT's “missing semester” has an excellent lecture video and notes.
• vimtutor is a program included with vim that will guide you through usage – run it from the command line.
• vim-wiki

Victoria's review: a minimal vim session experience:

1. vim $filename → opens a file in vim. If that file doesn't exist or you opened it in the wrong filepath, you will see an empty blank vim that says [NEW] at the bottom
2. i → puts you in insert mode so you can freely type and move your cursor around. Says – INSERT – in bottom left.
3. esc → gets you out of insert mode

move around

1. 0 puts your cursor to the beginning of the line (in command mode)
2. $ puts your cursor to the end of the line (in command mode)
3. Shift + i puts your cursor to the beginning of the line and opens insert mode
4. Shift + a puts your cursor to the end of the line and opens insert mode
5. o opens insert mode on a new line below your cursor
6. up and down arrows move you up and down each line but to move between lines click g then up or down arrow
7. u undo last change (in command mode)

close vim temporarily

• Ctrl + z puts the vim window to “sleep” and brings you back to the terminal
• fg brings you from the terminal back into the last script in vim you were working on

exit

• :q → quits vim
• :wq → saves what you wrote and quits vim
• :q! → does not save what you wrote and quits vim
