Vim configuration details

 

1. VIM configuration file 1. How should VIM be set to allow users to define their own configurations to display text? The two configuration files will be read during the running of VIM. (1) The ". exrc" configuration file under the Home Directory, which takes effect for users in the Home Directory (personal) (2)/etc/vimrc configuration file, which takes effect for all users (global) 2. The following describes how to configure VIM in user-defined mode. The configuration steps are as follows: 1) Step 1: create a new one named "under your home directory (/home/XXX".Exrc files [Root @ Mylinux ~] Touch. exrc 2) Step 2: Open ". exrc" in the vim editor and write related Vim configuration options. Common configurations are shown in the following table. [Root @ mylinux ~] Vim. exrc VimCommon configuration options of configuration files Set nocompatible Do not use the VI keyboard mode, but Vim's own Syntax on Highlight the syntax Set history = 100 Number of lines to be recorded in the history file Set nobackup I'm not used to having one more ~ Suffix backup file Set autoindent shiftwidth = 4 Enable auto indent and set the auto indent width to 4 Set background = dark Highlight a dark font (for example, comment) Set incsearch When searching, the entered words are highlighted by characters Set hlsearch Highlight the searched string (nohlsearch can be disabled) Set tabstop = 4 Change the tab to a 4-character width. Set shiftround Use> or <to adjust the width according to shiftwidth Set nu Show row number Set encoding = UTF-8 Display the encoding used (depending on the "Lang environment variable ") Set fileencodings = UTF-8, Latin1 The sequence in which Vim attempts to automatically determine the encoding of Files (Note: The Vim encoding used when writing files should not be in vimrc or. in exrc, VIM automatically sets this variable based on the judgment result after the file is loaded. This variable is modified and saved only when you want to convert the storage encoding of the file) Set termencoding = UTF-8 Encoding type used for output to client terminal (TERM) Set ambiwidth = double Display Chinese Characters in two widths Set clipboard + = unnamed Share clipboard with windows Filetype on Detect file types Filetype plugin on Load file type plug-in Filetype indent on Load indent files for a specific file type Set iskeyword + =_, $, @, % ,#,- Do not separate words with the following symbols by line breaks Set laststatus = 2 Always display status bar Set statusline = % F % m % r % h % w/[POS = % l, % v] [% p %] // Encoding: /% {(& fenc = /"/")? & Enc: & fenc }%{ (& bomb? /"[BOM]/":/"/")} // % {strftime (/"% Y-% m-% d/-/% H: % M /")} Content displayed in the VIM status line (including file type and decoding) Set smartindent Provides automatic indentation for C Programs Set cindent Use a C-style indent Scheme Set ignorecase Set list Case Insensitive during search Display the tab (ctrl + I) and the end of the line sign ($) Colorscheme desert Colorscheme evening Colorscheme default Vim Color Scheme

1. Folding Mode  You can use the 'foldmethod' option to set the foldmethod: Set OFDM = *****. There are 6 Ways to select the fold: Manual manual definition folding More indent indicates more fold Expr uses expressions to define collapse Syntax uses syntax highlighting to define collapse Diff folds Unchanged text Marker folds the mark in the text Note that each folding method is incompatible. If expr is not used and marker is used, the indent and marker modes are used in turn. When using this function, use the: set OFDM = marker command to set it to the marker foldmethod ). To make the folding take effect every time vim is opened, add the settings in the. vimrc file, such as adding: set OFDM = syntax, just like adding other initialization settings. 2. Fold command After the folding method is selected, we can implement the folding we need for some code. Because I use more indent and marker, their usage is used as an example: If the indent method is used, vim automatically folds the middle part of the braces, and we can directly use these ready-made folding results. In a foldable place (in the middle of braces ): Zc folding ZC folds all nested folding points in the range Zo unfold and fold ZO expands all nested folding points in the range [Z to the start of the current fold. ] Z to the end of the currently opened fold. Zj moves down. To the start of the next fold. The closed folding is also included. Zk moves up to the end of the previous fold. The closed folding is also included. When using the marker method, you need to use a tag to identify code folding. The default value of the system is {And}. Do not change it :) We can use the following command to create and delete a fold: Zf creates a fold, for example, in the marker mode: Zf56G: Creates code folding from the current row to 56 rows; 10zf, 10zf +, or zf10 labels, create code folding from the current row to the last 10 lines. 10zf-or zf10 labels, create code folding from the current row to the previous 10 lines. At ZF %, create the matching brackets (), {}, [], <>, etc.) from the current row ). ZD Delete is the folding of the cursor. Valid only when 'foldmethod' is set to "Manual" or "marker. ZD loop Delete refers to the folding under the cursor, that is, nesting Delete fold. Valid only when 'foldmethod' is set to "Manual" or "marker. Ze removes all folds in the (eliminate) window. Valid only when 'foldmethod' is set to "Manual" or "marker.
