Nvim Configs

My nvim configs.

Install steps:

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

git clone this repo into your should be into your ~/.config, so that you have a ~/.config/nvim/init.vim
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
install vim-plug
- run nvim
- run :PlugInstall
install fzf
- mac: brew install fzf
  - To install useful key bindings and fuzzy completion:
  - $(brew --prefix)/opt/fzf/install
- ubuntu: sudo apt install fzf
install ag
- mac: brew install the_silver_searcher
install ctags
- mac: brew install --HEAD universal-ctags/universal-ctags/universal-ctags
- ubuntu: sudo apt install universal-ctags
install rg
- mac: brew install ripgrep
- ubuntu: sudo apt install ripgrep

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

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)
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"

Make sure go >= 1.19 is installed on your machine
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/
```
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:
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
See vim-go cheatsheet
Also read the vim-go section of the init.vim to see custom mappings

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
