vim

things to do after vimtutor

By reading the contents of this repository I realized that this is the things to do after finishing the vimtutor:

learn how to navigate the documentation
- ctrl-] to follow a vimdoc link
- ctrl-o or ctrl-t to go back
learn about text-objects
- :help Q_to cheatsheet
- :help text-objects - verbose
:help quickref skim over quickref just to know it exists and what's there (it's like a cheatsheet)
when lurking other people's .vimrc, a one-sentence description of the options assigned with set can be seen in :help option-list

things I wanna do

Apply gq (break lines at column 80) in the whole file and keep the cursor position.

things I wanna learn

macros
windows/buffers management
linting
do something on save

cheatsheet

This is personal. I'm not taking notes of things I already memorized.

The commands are usually composed of a verb and a noun. Example: dw, stands for delete a word.

Tip: usually the same key used two times in a row applies the verb in the whole line. Examples: dd deletes the whole line, cc change the whole line.

motion

See :h motion for more info.

mapping	summary
`f<char>`	(f)ind a char forward in a line and move to it (`F` goes backward)
`t<char>`	find a char forward in a line and move un(t)il it (`T` goes backward)
`;`	repeat last `f`, `F`, `t` or `T` command
`,`	repeat last `f`, `F`, `t` or `T` command, but in opposite direction
`H`, `M`, `L`	move (H)igh, (M)iddle, or (L)ow within the viewport
`C-u`, `C-d`	move (u)p or (d)own

Text Objects

Tip: prefer using text-objects rather than motions in order to increase repeatability.

See :h text-objects for more options.

mapping	operation
`iw`, `aw`	"inner word", "a word" (a word includes the space)
`is`, `as`	"inner sentece", "a sentece"
`ip`, `ap`	"inner paragraph", "a paragraph"
`i)`, `a)`	"inner parenthesis", "a parenthesis"
`i'`, `a'`	"inner single quote", "a single quote"
`it`, `at`	"inner tag", "a tag" (HTML tag)

random tips

:set nu or :set number - line numbers
:set ai | :set noai - enable/disable autoindent
:set visualbell - blink screen instead of sound
:ab md mydomain.intranet.com - when you type md it becomes mydomain.intranet.com
visualy select part of the text and :'<,'>$!sort - sort the lines
:noh - disables search highlight
set a default font in gvim: :set guifont=*, choose the font config in the dialog box, then use :set guifont? to see what you should put in your .vimrc.

basic .vimrc options

colorscheme evening
set number
set tabstop=2
set showcmd
set cursorline " gutter

sensible.vim

Avoid too much configurations, but take a look at this one (which claims to be "defaults everyone can agree on"):
https://github.com/tpope/vim-sensible

It enables things like <C-L> to clear hlsearch, <C-W> to delete previous word when in INSERT mode, etc.

install vim-plug

The vim-plug is useful to install/update vim plugins.

Here's a way to install it at startup:

add this to your .vimrc

if empty(glob('~/.vim/autoload/plug.vim'))
  silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

Syntax of the language: Verb + Noun

Example:

d for delete
w for word
combine to be "delete word"

Some verbs:

d: delete
c: change (delete and enter insert mode)
>: indent
v: visually select
y: yank (copy)

Some nouns related to motions:

w: word
b: back
2j: down 2 lines

Some nouns related to text objects:

iw: inner word (works from anywhere in a word)
it: inner tag (the contents of an HTML tag)
i": inner quotes
ip: inner paragraph
as: a sentence

Some nouns related to parameterized text objects

f, F: find the next character, including it.
t, T: find the next character, excluding it.
/, ?: search the string, not including the string.

Tips:

use :set relativenumber
"visual mode is a smell"

plugin suggestions

Surround. e.g.:
- ds": delete surrounding quotes
- cs(": change surrounding parens to quotes
- ysiw": add double quotes around the word
- cst<h2>: change surrounding tag to <h2>
