Configuration

Base configuration is generated using vim-bootstrap.com and then patche files are created for each programming languages or frameworks. More customized configuration is created manually in local_bundles.vim and local_init.vim. To use the patch files, the key let g:vim_bootstrap_langs and leg g:vim_bootstrap_frams must be set to "" first then the file patch is applied sequentially using command patch -p 1 init.vim vim-bootstrap/<patch_name>.vim.patch. To revert the patch, use the *.revert patch files, but it must be applied from the most recent patch first.

Use these steps to generate the patch files for specific programming language or framework. Firstly, generate vim configuration for the specific programming language or framework using vim-bootstrap.com and rename as <programming language or framework>.vim. Then, use these commands to generate the patch files.

cd vim-bootstrap
sed -Ei "s/let g:vim_bootstrap_langs = \".*\"/let g:vim_bootstrap_langs = \"\"/g" <config_name>.vim
sed -Ei "s/let g:vim_bootstrap_frams = \".*\"/let g:vim_bootstrap_frams = \"\"/g" <config_name>.vim
sed -Ei "s/^(\" vim-bootstrap).*$/\1/g" <config_name>.vim
diff -u init.vim <config_name>.vim > <config_name>.vim.patch
diff -u <config_name>.vim init.vim > <config_name>.vim.reverts

Make sure that the init.vim file that is used for generate patch file are the same as init.vim.general. We also use separate python environment for vim configuration.

python3 -m venv ~/.config/nvim/env
pip install pynvim
deactivate

Also install npm package for neovim, the command below is used when the node package is installed through package management system.

sudo npm install -g neovim

Install vim plugins using this command.

nvim +PlugInstall +qall

The current bootstrap keys

let g:vim_bootstrap_langs = "go,html,javascript,python,ruby,rust,typescript"
let g:vim_bootstrap_editor = "nvim"                             " nvim or vim

Configuration for Debian

Debian buster still provides neovim with version 0.3 which is not compatible with configuration generated from vim-bootstrap.com. We need to add the following changes to the vim configuration for Debian.

init.vim

" comment these configuration
"au TermEnter * setlocal scrolloff=0
"au TermLeave * setlocal scrolloff=3

local_init.vim

" disable rnvimr plugin
let g:rnvimr_ex_enable = 0

" disable go warning for neovim version
let g:go_version_warning = 0
