Vim

Random snippets of Vim that I need to remember and use or else they will fade

:set

Print current settings - Useful to figure out tab stops etc.

Spacing + tabs

#

expandtab = use spaces vs tabs
noexpandtab = use tabs vs spaces

Re-indent file after making any type of tabbing changes.

Text objects

• gg - Go to top of page
• ) - Jump forward to next sentence
• ( - Jump backwards to next sentence
• } - Jump forward one paragraph
• { - Jump backwards one paragraph
• cc - Delete the current line and go into insert mode

Word text objects

#

• e moves you to the end of a word word perfect for then issuing a daw or diw
• diw delete an inside word that your cursor is sitting on.

Deleting

#

Stop using d$ to delete to the end of line but use c$ instead, this puts you into auto insert mode right after deleting.

Cleanup whitespace

#

We have a custom function called TrimWhiteSpace - Call that when you want to rid yourself of trailing white space. There’s also a status bar check that will display an icon if you have trailing whitespace.

Write to current file with sudo if you don’t have editing rights

#

:w !sudo tee %

LSP Python but can be for other languages as well

• gd => go to def
• ctrl-o => go back
• shift-k => signature
• space-e => show error

Editing multiple lines aka inserting something like a “-” at the front of something

#

1. Hit ctrl + v to go into visual block mode. Do not confuse this with shift + v which will place you into visual line mode.
2. Select to the bottom of the selection and hit shift + I
3. Add what you want to the front and hit esc. - This should then apply to all of the lines you selected.

Quickly go to the bottom of a file and add new content
