Install steps:

After the first step, the following steps are not in any proven or fully correct order; some steps mayyyy be missing.

1. git clone this repo into your should be into your ~/.config, so that you have a ~/.config/nvim/init.vim
2. figure out what python path and what pip path to use
   • on el8 instance, use let g:python3_host_prog = "/usr/bin/python"
   • on mac, if python3 installed, use let g:python3_host_prog = "python3"
   • use pip3 which is linked to the python instance, to install the relevant packages
3. install vim-plug
   • run nvim
   • run :PlugInstall
4. install fzf
   • mac: brew install fzf
     • To install useful key bindings and fuzzy completion:
     • $(brew --prefix)/opt/fzf/install
   • ubuntu: sudo apt install fzf
5. install ag
   • mac: brew install the_silver_searcher
6. install ctags
   • mac: brew install --HEAD universal-ctags/universal-ctags/universal-ctags
   • ubuntu: sudo apt install universal-ctags
7. install rg
   • mac: brew install ripgrep
   • ubuntu: sudo apt install ripgrep

Debugging steps:

• Every time you modify your init.vim, you can run :so with that file open to reload the configs. Or, just restart nvim
• Run :checkhealth to see if nvim is complaining about anything, and to see specific diagnosed problems or steps to solve them

Python-specific install steps:

1. install flake8 pip install flake8
2. install isort pip install isort
3. install pynvim
   • pip install pynvim

iTerm install steps:

1. Follow https://stackoverflow.com/a/46018502 to add the following iTerm mappings:
   • add CMD-s: :w!\n (saves file)
   • add CMD-/: gcc (comments out code)
2. Install Devicons font
   • in OSX terminal: run cd ~/Library/Fonts && curl -fLo "Droid Sans Mono for Powerline Nerd Font Complete.otf" https://github.com/ryanoasis/nerd-fonts/raw/master/patched-fonts/DroidSansMono/complete/Droid Sans Mono Nerd Font Complete.otf
   • in iTerm preferences: go to Profiles -> Text -> Font -> check "Use a different font for non-ASCII text → DroidSansMono Nerd Font"

Go install steps:

1. Make sure go >= 1.19 is installed on your machine
2. Make sure go and go binaries (e.g. gopls, after nivm installs it) can be accessed from your PATH.
   • You can add this to your .bashrc for el6:

     PATH=$PATH:/opt/golang1.19/bin
     PATH=$PATH:/home/vagrant/go/bin/
     

   • Generally, e.g. for mac, add this to your .bash_profile:

     PATH=$PATH:~/go/bin/
     

3. With nvim open, run :GoUpdateBinaries. You may need to restart nvim to see everything working. If everything was installed correctly, you should be able to see auto-completion and docstrings like these:
4. If you get this error: "Spawning language server with cmd: gopls failed. The language server is either not installed, missing from PATH, or not executable."
   • Revisit step 2: You'll need to make sure you can access gopls from your PATH
5. See vim-go cheatsheet
6. Also read the vim-go section of the init.vim to see custom mappings

CoC

• CoC configs are currently commented out.
• if desired, un-comment and install node>=12

Cool Commands this gives you

This is a list of commands you can use with these configs. Some of these come from base vim, but I threw them in here anyways.

NOTE: C: ctrl, S: shift

• C-p fzf
  • C-t new tab
  • C-v vertical split during fzf
  • C-x horizontal split during fzf
• C-w-direction: switch panes
• space-direction: also switch panes
• space 1, 2, n to choose tabs
• C-S-Left, C-S-Right to switch tabs left and right
• :ag to search for string in project
  • Using Rg, outdated: (space-f to search in project)
• gcc: comment
• C-r: redo
• c-a-": change around ", etc.
• ysiW-": add " around W
• C-6 go between previous and next
• space-=, space-minus : increase pane size
• space-w: picks nvim window, but doesn't work currently
• * highlight occurrences of word cursor is on/ go to next occurence
• C-o show most recently updated? opened? files
• tab, S-tab: indent + un-indent
• [h —> previous git hunk
• ]h —> next git hunk
• C-n : multi-select
• C-S-Down: multi-cursor select down
• C-S-Up: multi-cursor select up
• space-s: git blame line
• space-c: in visual mode, copy text to OS clipboard
• tags:
  • space-t : generate tags
  • C-} : jump to tag (this is OP... sometimes)
• gg=G : auto-indents the whole file. This works... sometimes
