vimrc vim is a high-performance editor, but unlike Visual Studio and jupyter notebook, for example, the UI Somehow the threshold is high because it is not fulfilling at all (without using a plug-in). I'm not very good at using it, so it feels like I'm practicing ... But ** I've been wondering or not recently thinking that vim's good point is that you can write crisply ** if you get used to the default key bindings, and ** you can customize it freely **. Various plugins are published on github. With that said, today I would like to introduce the .vimrc that I am using now.

I copy and paste the .vimrc introduced in here and customize it a little. ** I want to make .vimrc with all copy! In that case, please copy and paste after going to [here](# enable copy and paste via clipboard) and adjust. ** **

Beginner's Guide

If you are not new to this, please skip to [here](#first setting).

Let's create .vimrc for the time being.

$ cd
$ vi .vimrc

** You might think, "Well, is vim's startup command vi instead of vim?" **, but at least for now, both can be considered the same command.

For the time being, I think that you should have opened .vimrc in vim. I think vim is quite difficult if you don't get used to it, so for the time being, I will only introduce the basic understanding and commands that are in the beginning.

Basic understanding

vim has several modes.

--Normal mode (command input) --Insert mode (text editing) --Visual mode (range selection)

Normal mode is a mode for entering commands with vim. It will be in this mode when you open the file with vim. In other modes, press ʻEsc to enter this mode. Insert mode is a mode for rewriting sentences and chords themselves. If you enter ʻi or ʻoin normal mode, you will be in this mode and you will be able to edit the text. Visual mode is a mode for selecting a range. Enterv` etc. in normal mode to enter this mode. You may not use it much at first.

command

For the time being, I think it's okay if you keep in mind only the following commands in this article. If you don't have enough, please google at any time.

Commands in normal mode

Commands in other modes

Initial setting

Write the following script at the beginning of .vimrc. This is a script to enable Japanese.

.vimrc

set encoding=utf-8
scriptencoding utf-8

If you are writing .vimrc for the first time, write it so far and press ʻEsc to enter normal mode, save it with: wq` and close it. If you open it again, Japanese will be valid.

Enable copy and paste via clipboard

If you want to do everything with copy and paste, do it manually so far. Copying and pasting normally should be annoying. If you do, enter : q! In normal mode and close it without saving if it is troublesome to fix.

"----------------------------------------------------------
"Paste from clipboard
"----------------------------------------------------------
"Prevent automatic indentation when pasting from the clipboard in insert mode
if &term =~ "xterm"
  let &t_SI .= "\e[?2004h"
  let &t_EI .= "\e[?2004l"
  let &pastetoggle = "\e[201~"

  function XTermPasteBegin(ret)
    set paste
    return a:ret
  endfunction

  inoremap <special> <expr> <Esc>[200~ XTermPasteBegin("")
endif

You can now copy and paste from the clipboard. In other words, you will be able to copy texts from internet sites and paste them into files opened with vim. Convenient!

Color scheme

The color scheme I personally tried but the wreckage is commented out ... molokai is famous. However, I personally like iceberg. Also, I will introduce pyceberg, which is slightly customized to make it easier for me to see, later ~~ (Daima) ~~.

Highlight unnecessary space

Makes whitespace characters in the code visible with a red highlight. I can't compile because of space! I'm very grateful for that. What's more, you can even delete all the unwanted spaces highlighted with the command : FixWhitespace! Well, don't rely too much on this, and always code carefully.

It's super important for writing tabs, indents, and easy-to-read code. I personally feel that it is difficult to see if the indent width is too large, so I set it to 2, but for some reason it becomes 4 without permission when writing Python code. Well, Python has a tacit understanding and the indent width is like 4, so it's good. It will be [Indent or Visualization](#Indent Visualization).

.vimrc

"----------------------------------------------------------
"Tab indent
"----------------------------------------------------------
set expandtab "Replace tab input with multiple blank inputs
set tabstop=2 "The width occupied by tab characters on the screen
set softtabstop=2 "The width that the cursor moves with the tab key and backspace key for consecutive blanks
set autoindent "Continue indenting the previous line at line break
set smartindent "Check the syntax of the previous line at line breaks and increase or decrease the indentation of the next line
set shiftwidth=2 "Width that increases or decreases with smart indent

String search

This is also an important setting. String search becomes convenient.

.vimrc

"----------------------------------------------------------
"String search
"----------------------------------------------------------
set incsearch "Incremental search.Search for each character entered
set ignorecase "Search patterns are not case sensitive
set smartcase "If the search pattern contains uppercase letters, it is case sensitive
set hlsearch "Highlight search results

"Press the ESC key twice to switch highlights
nnoremap <silent><Esc><Esc> :<C-u>set nohlsearch!<CR>

By the way, the character string search is / (the character string you want to search) Character string replacement is basically :% s / (character string to be replaced) / (character string after replacement).

Cursor movement etc.

In vim, in normal mode, you can use h, j, k, l to move tolower left, upper right, respectively, but when moving with such a command, one line wraps and is displayed because you wrote a long code. If it is, for example, if you move with j, the cursor will move to the next line instead of one line down as it looks. Here, it is set to solve it and highlight the cursor line.

"----------------------------------------------------------
"cursor
"----------------------------------------------------------
set whichwrap=b,s,h,l,<,>,[,],~ "You can move the cursor left and right from the end of the line to the beginning of the next line.
set number "Show line number
set cursorline "Highlight cursor line

"If the line is wrapped, move the cursor by the displayed line instead of the line.
nnoremap j gj
nnoremap k gk
nnoremap <down> gj
nnoremap <up> gk

"Enable backspace key
set backspace=indent,eol,start

Correspondence of parentheses and tags

The corresponding parentheses flash for a moment while coding. This is useful when writing a lot of parentheses.

.vimrc

"----------------------------------------------------------
"Correspondence of parentheses and tags
"----------------------------------------------------------
set showmatch "Display the correspondence of parentheses for a moment
set matchtime=3
set matchpairs& matchpairs+=<:>
source $VIMRUNTIME/macros/matchit.vim "Vim's "%To extend

Mouse activation

I can't use the mouse with the default vim. You can't use the trackpad either. So let's set it.

"----------------------------------------------------------
"Cursor movement and scrolling with mouse
"----------------------------------------------------------
if has('mouse')
  set mouse=a
  if has('mouse_sgr')
    set ttymouse=sgr
  elseif v:version > 703 || v:version is 703 && has('patch632')
    set ttymouse=sgr
  else
    set ttymouse=xterm2
  endif
endif

File management

When I edit a file with vim, it automatically creates a backup file and a swap file, but I don't need it separately, so turn it off. (If you need a file backup, I think you should use git in the first place)

.vimrc

"----------------------------------------------------------
"File management
"----------------------------------------------------------
"Do not create backup or swap files
set nowritebackup
set nobackup
set noswapfile

Display relation

Visualize whitespace, line breaks, tabs, etc. I will wrap it when the sentence becomes longer.

"----------------------------------------------------------
"Display relation
"----------------------------------------------------------
set list "Visualization of invisible characters
set wrap "Wrapping long text
set colorcolumn=100 "Put a line on the 100th character
"Disable screen bell
set t_vb=
set novisualbell
"Clean invisible characters in Unicode
set listchars=tab:»-,trail:-,extends:»,precedes:«,nbsp:%,eol:↲

Macros and key settings

Here, the default key bindings are overridden or newly set for intuitive use. Please add or delete as you like.

--nnoremap is the key setting in normal mode --ʻInoremap is the key setting in insert mode --vnoremap is the key setting in visual mode --is theShift key --is theCtrl` key
