 36 | ## Your first VimRC: How to setup your vim's vimrc
 37 | https://www.youtube.com/watch?v=n9k9scbTuvQ
 38 | 
 39 | Source or "execute" everything in a file with `source %`.  
 40 | This applies changes made to .vimrc.  
 41 | 
 42 | Make sure to create the undodir at `~/.vim/undodir`  
 43 | 
 44 | Run the following command to install the plug vim plugin manager
 45 | ```console
 46 | curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
 47 |     https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
 48 | ```
 49 | 
 50 | Open up the .vimrc and add in your plugins.
 51 | Then source the .vim with `:source %s`.
 52 | Then install plugins with `:PlugInstall`.
 53 | 
 54 | Make YCM work:
 55 | ```console
 56 | $ cd ~/.vim/plugged/YouCompleteMe
 57 | $ python3 install.py
 58 | ```
 59 | 
 60 | Add some nice remap to make things easier:
 61 | * `<leader>h`: Move to window on the left
 62 | * `<leader>l`: Move to window on the right
 63 | * `<leader>j`: Move to window on the bottom
 64 | * `<leader>k`: Move to window on the top
 65 | 
 66 | * `<leader>u`: Show undo tree
 67 | 
 68 | * `<leader>pv`: Open up file tree
 69 | 
 70 | * `<leader>ps`: (Project Search) searches for stuff using ripgrep (Make sure to install ripgrep on your system)
 71 | 
 72 | * `<leader>gd`: Go to definition
 73 | * `<leader>gr`: Go to references  
 74 | 
 75 | ## VIM Movements P2: 5 moves to make you better ked
 76 | https://www.youtube.com/watch?v=QN4fuSsWTbA
 77 | 
 78 | * Use Ctrl-c or Ctrl-open bracket instead of Esc.  
 79 |   Instead of using the CAPS LOCK key for Esc, you can use it for CTRL.
 80 | 
 81 | * When using f and t, you can use `,` to go backwards and `;` to go forwards to search for the same letter without repeating the same command
 82 | * Use `c` instead of `d` to enter insert mode
 83 | * You can use `i` and `a` in conjunction with c or d to remove whatever's inside {}, [], "", '', etc.
 84 |   E.g. ci" will delete everything within the following string: "Hello, world".
 85 |   ca" will delete everything inside the string as well as the "". 
 86 | * Marks allow jumping to points in a file: `mJ` will create a mark called J. `'J` will jump to the mark. Note: Capital letter are marks that are unique across multiple files while lowercase letters are for local file marks.
 87 | * Bonus remap allows you to move highlighted regions up or down:
 88 | ``` {.vimscript}
 89 | vnoremap J :m '>+1<CR>gv=gv
 90 | vnoremap K :m '<-2<CR>gv=gv
 91 | ```
 92 | 
 93 | ## Using Vim: Vim + Git - Fugitive
 94 | https://www.youtube.com/watch?v=PO6DxfGPQvw
 95 | 
 96 | `<leader>gs`: Git Status  
 97 | 
 98 | Use `s` to stage and `u` to unstage.  
 99 | 
100 | `:Gcommit`: Commits stuff  
101 | 
102 | `:Gpush`: Pushes stuff  
103 | 
104 | `:Git merge <branchname>`: Merge  
105 | 
106 | Use `dv` on the file you want to resolve if you have merge conflicts.  
107 | The window on the left should be the current branch, the window on the right should be the one you just merged from, and the middle window is the resulting merge.    
108 | 
109 | `<leader>gf`: Grab from the window on the left (Use 'gu' if using dvorak)  
110 | 
111 | `<leader>gj`: Grab from the window on the right (Use 'gh' if using dvorak)  
112 | 
113 | `Ctrl-w` and `ctrl-O`: save and close  
114 |

138 | ## Using Vim: My Vim Workflow - Solving a bug
139 | https://www.youtube.com/watch?v=-I1b8BINyEw
140 | 
141 | ### First you want some plugins
142 | 
143 | * Gruvbox: "The greatest colorscheme ever bestowed to mankind"
144 | * COC: For autocomplete
145 | * Fzf: File finding
146 | 
147 | Colorscheme:
148 | ```
149 | colorscheme gruvbox
150 | ```
151 | 
152 | Nice remaps for coc and jumping to definition/references:
153 | ```
154 | nmap <leader>gd <Plug>(coc-definition)
155 | nmap <leader>gr <Plug>(coc-references)
156 | ```
157 | 
158 | Fzf remap to make searching for files easier:
159 | ```
160 | nnoremap <C-p> :GFiles<CR> 
161 | ```
162 | 
163 | ### Commands Used 
164 | 
165 | `Ctrl-p`: Remap for :GFiles. Use it to search for a file. Works even for searching large codebases.  
166 | 
167 | `<leader>gd`: Jump to definition  
168 | 
169 | `Ctrl-^`: Jumps to the last file you were in
170 | 
171 | `Ctrl-o`: Go back to last position
172 | 
173 | `Ctrl-i`: Go forward position (Opposite of Ctrl-o)
174 | 
175 | ## VIM: Coolest Vim Command
176 | https://www.youtube.com/watch?v=E7NBhSsZouc
177 | 
178 | Let's say you have a line of code:
179 | ```javascript
180 | const res = await fetch("http://localhost:8002", {
181 | ```
182 | If you wanted to change the `http://localhost:8002` string inside the quotes,
183 | you don't have to use `f"` to go to the quotes, you can just use `ci"`. Vim automatically jumps to the nearest quote.
184 |
