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.

Instalação

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 base Vim package. They can be listed in last line mode by typing colorscheme, 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:

FILE ~/.vimrc
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.

Primeiros passos

O Vim contém um tutorial que deve durar cerca de 30 minutos do começo ao fim. Inicie-o usando o comando vimtutor:

user $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 knowing how to use it, it may not be evident 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.
