VIM-Pathogen

Manages VIM plugins.

Installation Steps

Commands to setup Pathogen:

mkdir -p ~/.vim/autoload ~/.vim/bundle
curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim

Then add this to the .vimrc:

execute pathogen#infect()

NERDTree

The installation of NERDTree was not done using pathogen. It was done manually.

Installation Steps

Without Pathogen

mkdir -p ~/.vim/
cd /tmp/
curl -L -o nerdTree.6.10.9.zip https://github.com/preservim/nerdtree/archive/refs/tags/6.10.9.zip
unzip nerdTree.6.10.9.zip
mv nerdtree-6.10.9/* ~/.vim/

With Pathogen

git clone https://github.com/preservim/nerdtree.git ~/.vim/bundle/nerdtree

natebosch/vim-lsc

This plugin is NodeJS extension host for vim.

Installation Steps

cd ~/.vim/bundle
git clone https://github.com/natebosch/vim-lsc

That's all. If VIM Pathogen is installed and configured in the .vimrc then it would be picked up. .vimrc already contains the necessay configuraion required to use it, however, a language server needs to be installed:

Configuring LSP for Go

• Install gopls

$ GO111MODULE=on go get golang.org/x/tools/gopls@latest

• Update .vimrc to use gopls for Go files

let g:lsc_server_commands = {'go': 'gopls'}

• Update .vimrc to configure vim-lsc

" Complete default mappings are:
let g:lsc_auto_map = {
    \ 'GoToDefinition': 'gd',
    \ 'GoToDefinitionSplit': ['<C-W>]', '<C-W><C-]>'],
    \ 'FindReferences': 'gr',
    \ 'NextReference': 'g<C-n>',
    \ 'PreviousReference': 'g<C-p>',
    \ 'FindImplementations': 'gi',
    \ 'FindCodeActions': 'ga',
    \ 'Rename': 'gR',
    \ 'ShowHover': v:true,
    \ 'DocumentSymbol': 'go',
    \ 'WorkspaceSymbol': 'gS',
    \ 'SignatureHelp': 'gm',
    \ 'Completion': 'completefunc',
    \}              

Shortcuts

• gd: For navigating to the function defintion
• gi: For navigating to the implementation
• gr: For navigation to the references
• K: To get the documemntation
