Vim
Vim (Vi IMproved) é um editor de textos baseado no vi. Ele pode ser usado através da interface de linha de comando ou como uma aplicação com interface gráfica.
Vim should not be confused with Neovim, a similar program which may be used in its place.
The Vi article provides general information on vi-like editors. See the Vim guide for an introductory tutorial on vi-like editor usage. See the text editor article for general information on installing and configuring text editors in Gentoo.

Emerge
Se não for necessário o suporte ao X Window System, basta instalar o pacote app-editors/vim:
root #
emerge --ask app-editors/vim
Softwares Adicionais
Gvim
Para instalar o Vim tanto com a interface baseada em ncurses (/usr/bin/vim) como a interface gráfica (para o X Window System - /usr/bin/gvim), instale o pacote app-editors/gvim:
root #
emerge --ask app-editors/gvim
Packages
Vim has support for packages, which provide a native mechanism to extend functionality. Read the built-in packages documentation for more information: :help packages
Plugins
A categoria app-vim fornece uma boa quantidade de definições de sintaxe adicionais, plugins e outros conteúdos relacionados ao Vim.
Use emerge ou eix para obter uma visão geral dos pacotes disponíveis na categoria app-vim:
user $
emerge --search "%@^app-vim"
user $
eix -cC app-vim
Not all Vim plugins will be available in the Gentoo repository. Vim now includes native packages, as a way to install plugins, and there are also several plugin managers for Vim.
Configuração
Arquivos
O Vim pode ser configurado para cada usuário ou através de um arquivo de configuração global, efetivo para todo o sistema:
- /etc/vim/vimrc - O arquivo global de configurações.
- ~/.vimrc - O arquivo de configuração local, específico para cada usuário. O til (~) significa que este arquivo está localizado na pasta do usuário.
Color schemes
About a dozen color schemes are shipped with the core Vim package. They can be listed in last line mode by typing colorscheme (followed by a space), then pressing either Ctrl+d or pressing the Tab key twice:
:
colorscheme
blue darkblue default delek desert elflord evening industry koehler morning murphy pablo peachpuff ron shine slate torte zellner
They can be changed in Vim by using the colorscheme (alternatively use colo) command while in last line mode:
:
colorscheme peachpuff
Color schemes can be permanently applied in the .vimrc file. Note that the syntax on
line is also needed for activation:
colorscheme peachpuff
syntax on
The first line sets the default color scheme while the last line activates the color scheme.
Selecting vi editor and system default editor
If Vim - and only Vim - is installed, the vi command should launch Vim. If other vi-like editors are installed, eselect may be used to choose which editor the vi command launches.
The text editor article may also be of interest for setting a system default editor, if Vim is to be set as the default.
Gentoo syntax
To enable support for the Gentoo syntax plugin (app-vim/gentoo-syntax) within vim, add the following lines to the user's ~/.vimrc file:
filetype plugin on
filetype indent on
leave_my_textwidth_alone
By default, Vim and Neovim do not hard-wrap lines[1], i.e., typing on a line longer than a certain length does not create a new line. However, Gentoo installs config files for Vim[2] and Neovim[3] that cause lines longer than 78 characters in .txt files to be hard-wrapped. To override this behavior, the following should be specified in the user's ~/.vimrc file:
let g:leave_my_textwidth_alone=1
bug #559800 contains some discussion around this issue.

Invocation
From the command line:
user $

The vi command may also be used to launch Vim, if so configured.
Specify a name, to open an existing file, or to create a new one:
user $
vim <filename>
Primeiros passos
O Vim contém um tutorial que deve durar cerca de 30 minutos do começo ao fim. Inicie-o usando o comando vimtutor:

Dicas e truques
Usando Vim como ex ou ed na linha de commando
É possível usar o Vim para one-liners - comandos que podem ser usados em scripts ou na linha de comando para realizar modificações de maneira não vigiada.
Por exxemplo, o comando a seguir adiciona #
ao começo de cada linha no arquivo file.txt:
user $
vim -c ":%s/^/#/g" -c ":x" file.txt
O que acontece é que o Vim interpreta o que foi passado como comando (através da opção -c
). O primeiro comando é o comando de substituição do Vim (que é bem parecido ao do sed), o segundo é a instrução do Vim para salvar e sair do editor.
Alterar a codificação do arquivo
Para alterar a codificação de um arquivo para UTF-8. use o seguinte comando (na linha de comando do Vim):
:
e ++enc=utf8
Como mostrado na dica anterior, é possível fazer isto diretamente da linha de comando:
user $
vim -c ":wq! ++enc=utf8" file.txt
Troubleshooting
I'm trapped in vim!
For someone entering vim without first having learned how to use it, it may not be obvious how to quit.
Press esc several times, then :, q, enter. To quit without saving, press esc several times, then :, q, !, enter.
If several files are open, try pressing esc several times, then :, q, a, enter. To quit without saving, press esc several times, then :, q, a, !, enter.
If this doesn't help, and desperate measures are needed, something like killall vim may be a last ditch solution (from another terminal). Beware that this will terminate all the vim sessions for a user, without saving. If run as root, such a command will terminate all vim sessions for all users on the system.
Pastes are being tabbed
Say the following text is trying to be pasted into a Vim buffer:
some:
yaml:
- data
- structured
in:
- this
- shape
that:
- VIM
- may
not: like
Vim may interpret this with autotabbing, breaking the paste:
some:
yaml:
- data
- structured
in:
- this
- shape
that:
- VIM
- may
not: like
To correct this, run the following command: :set paste to enable Vim's paste mode, once the paste is completed, :set nopaste can be used to go back to the previous settings.

user $
vim foobar
E1187: Failed to source defaults.vim Press ENTER or type command to continue
