Vim Tips

This post is a aggregate of tips that I get it from vim

The ideal world of VIM

The ideal is one keystroke to move and one keystroke to execute.

VIM are optimized to repetition with dot . keystroke, most of the commands that we are used to do in other text editors is not optimized for repetition.

Example - Deletion a word

  • dw - needs set the cursor at start of word
  • db - needs set the cursor at end of word and use x to last character
  • daw - delete the word and the space. able use dot

Dont count if you can repeat

Following the tip above, in some cases repeat the dot command is more fast that count

Combine and Conquer

g, z, ctrl-w, [] are Operators Pending mode in most cases the first keystroke merely acts as a prefix for the second use one of these keytrokes more 2 times acts at current line

Set caps lock Off

It’s serious, just make it at system keyboard settings. :)

Visual Selection

  • gv is useful little shortcut. It reselects the range of text that was last selected in Visual Mode.
  • o in selection mode can be util to free hand selection
  • vit select the contents inside a tag
  • U acts in selected content transform it to UPPERCASE

In selection a text and after go to Ex mode set something like it at ex command: :'<,'>normal . can be read like: “For each line in the visual selection, execute the Normal mode . command.”

e.g:

var foo = 1
var bar = 2

A; add the semicolon at end of line, so we can run:

  • :'<,'>normal A; to add semicolon at endline of selected
  • :%normal A; to add semicolon at endline of entire file

Usefull tips

  • q: show the command-line window :help cmdwin
  • %: is a shorthand to current file
  • <ctrl-w> o: keep only the active window, closing all others
  • dt.: text object to delete at next . char
  • i or a: text object explanation: with i select inside the delimiter and a select around the delimiter
  • "/: Last search pattern

Marks

  • " Position before the last jump within current file
  • '. Location of last change
  • '^ Location of last insertion
  • '[ Start of last change or yank
  • '] End of last change or yank
  • '< Start of last visual selection
  • '> End of last visual selection
  • m{letter} create a mark
  • '{letter} use a mark.

Register

Black hole register = _

so for delete without copy you can _d{motion} to performs a true deletion

All the yanked text are inserted to unnamed register (default) and “0 register you can use: 0P to paste value inside 0 register.
