Meu VIM em 2020

guicarvalho profile image Guilherme Carvalho ・7 min read

A cerca de 2 anos comecei a me aventurar no VIM. Inicialmente não foi muito fácil, mas após algumas horas de estudo e prática as coisas começaram a sair naturalmente. Comecei a entender os benefícios em ter o modo comando e modo edição, mas ainda faltavam as facilidades de editores como o Sublime e VSCode para que de fato eu pudesse chamar o VIM de meu.

Qual minha stack?

Em 2020 continuo forte no Python, Javascript (React/React Native) e um pouco de Terraform (me aventuro as vezes kkkk), então alguns plugins estão diretamente ligados a esse mundo.

Coc.nvim

Depois de várias configurações e plugins (se quiserem posso fazer um post sobre isso), conheci o Coc.nvim, e que projeto amigos! Com ele podemos fazer o uso dos plugins de VSCode no VIM.

Minhas extensões

Leia extensões como plugins (se você é o carinha do VSCode). Para instalar é bem simples: CocInstall extension-name, segue a lista que estou usando atualmente:

  * coc-tsserver 1.5.2 ~/.config/coc/extensions/node_modules/coc-tsserver
  * coc-tabnine 1.2.2 ~/.config/coc/extensions/node_modules/coc-tabnine
  * coc-snippets 2.1.28 ~/.config/coc/extensions/node_modules/coc-snippets
  * coc-prettier 1.1.14 ~/.config/coc/extensions/node_modules/coc-prettier
  * coc-pairs 1.2.21 ~/.config/coc/extensions/node_modules/coc-pairs
  * coc-highlight 1.2.5 ~/.config/coc/extensions/node_modules/coc-highlight
  * coc-floaterm 0.0.7 ~/.config/coc/extensions/node_modules/coc-floaterm
  * coc-explorer 0.7.12 ~/.config/coc/extensions/node_modules/coc-explorer
  * coc-eslint 1.2.7 ~/.config/coc/extensions/node_modules/coc-eslint
  * coc-emmet 1.1.4 ~/.config/coc/extensions/node_modules/coc-emmet
  + es7-react-js-snippets [RTP] 2.8.0 ~/.config/nvim/plugged/vscode-es7-javascript-react-snippets
  + coc-python 1.2.12 ~/.config/coc/extensions/node_modules/coc-python
  + coc-json 1.2.6 ~/.config/coc/extensions/node_modules/coc-json
  + coc-html 1.2.4 ~/.config/coc/extensions/node_modules/coc-html
  + coc-css 1.2.3 ~/.config/coc/extensions/node_modules/coc-css

LSP para Terraform

Ainda não existe uma extensão pronta para o Terraform, mas isso não é um problema já que podemos fazer o download e colocar o server em nossa máquina: terraform-lsp.

$ cd terraform-lsp_0.0.10_darwin_amd64  # A pasta pode variar de nome
$ mv terraform-lsp terraform
$ mv terraform /usr/local/bin

Configurações

Assim como no VSCode você pode criar configurações globais e locais: CocConfig e CocLocalConfig respectivamente. Mantenho todas as configurações no arquivo global.

{
    "languageserver": {
        "terraform": {
            "command": "terraform-lsp",
            "filetypes": ["terraform"],
            "initializationOptions": {}
        }
    },
    "python.linting.flake8Args": [
        "--max-line-length=120"
    ],
    "eslint.autoFixOnSave": true,
    "explorer.icon.enableVimDevicons": true,
    "explorer.icon.enableNerdfont": true
}

Vim-clap

Outro plugin bem legal que encontrei é o vim-clap. Ele é um buscador que faz uso da funcionalidade floating_win no Neovim. Como ele faz uso de providers você precisa instalar alguns binários para utilizar alguns comandos de maneira mais performática:

$ brew install ripgrep ctags
$ alias ctags="`brew --prefix`/bin/ctags"
$ alias ctags >> ~/.zshrc  # or alias ctags >> ~/.bashrc

Depois de configurado:

Neovim exibindo janela flutuante com lista de arquivos do diretório atual.

Meu .config.nvim ou .vimrc

Se você utiliza Neovim e não mudou o nome do arquivo então para você é .init.nvim, mas se você está no VIM então é o seu .vimrc.

Para gerenciar meus plugins utilizo o vim-plug, esse cara é bem tranquilo de utilizar. Após instalar e declarar seus plugins no arquivo de configuração com Plug 'repo-identifier' só rodar :PlugInstall.

call plug#begin('~/.config/nvim/plugged')

Plug 'morhetz/gruvbox'
Plug 'challenger-deep-theme/vim', { 'as': 'challenger-deep' }
Plug 'neoclide/coc.nvim', {'branch': 'release'}

Plug 'ap/vim-css-color'
Plug 'hashivim/vim-terraform'
Plug 'tpope/vim-fugitive'
Plug 'airblade/vim-gitgutter'
Plug 'tpope/vim-surround'
Plug 'sheerun/vim-polyglot'
Plug 'voldikss/vim-floaterm'
Plug 'dsznajder/vscode-es7-javascript-react-snippets', { 'do': 'yarn install --frozen-lockfile && yarn compile' }
