My own configuration and cheatsheet for vim, feel free to copy and make suggestions.

1. Copy the .vimrc into your home directory (i.e. ~/) or symlink with ln -s /path/to/vim-config/.vimrc ~/.vimrc,
2. Install Vundle by running git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim,
3. Run vim +PluginInstall +qall in shell, or ":PluginInstall" in vim, to install all of the plugins with Vundle,
4. Symlink the language-dependent configurations (e.g. rb.vim or py.vim) to ~/.vim/ftplugin/LANGUAGE.vim,
5. (Optional) Reload live vim sessions with the command :source ~/.vimrc.

I use this in conjunction with iTerm and Visual Studio Code's theme

In order for YouCompleteMe to work, follow the installation instructions on their Github page for your system. On MacOS, the plugin only works with MacVim, which can be installed with Brew - trying to open the plugin directly will freeze the terminal. To install MacVim, run brew install macvim, and alias vim with alias vim="mvim -v".

Gutentags is used to generate ctags. In order for the plugin to run, must install ctag on your machine (i.e. sudo apt install exuberant-ctags).

See their Gihub page for information.

YouCompleteMe is a plugin for vim that has support for autocomplete. To enable it, run cd ~/.vim/bundle/YouCompleteMe && ./install.py --all to complete setup. See their Github page for more information on setup.

When the autcomplete shows up, use TAB key to cycle through suggestions or shift + TAB to cycle backwards.

CtrlP is a "Full path fuzzy file, buffer, mru, tag, ... finder for Vim".

To check what a key is current mapped, use nmap.

• grep -rnw './parent_path' -e 'keywords'

• In current pane, use :e FILE_NAME

NERDTree is a tool for browsing files in a tree similar to those of IDEs.

• ctrl + n - toggle NERDTree (a file tree browser), can be changed in the .vimrc file
• I (shift + i) - to toggle showing hidden files

• To select, v to select characters, V to select whole lines, or use the mouse to highlight when mouse mode is enabled,
• To copy, y for "yank",
• To cut, d,
• To paste before cursor press P. to paste after cursor press p.

Alternatively, in visual mode CTRL-c copies and CTRL-x cuts.

MacVim on MacOS and vim-gtk (should uninstall vim and install vim-gtk) should allow yank and cut to copy to system clipboard.

• zc closes a fold
• zo opens a fold

• :w writes the current changes to disk,
• <CTRL> z is a shortcut that writes changes to disk and changes back to normal mode.

In normal mode:

• :u or simply press u will undo a previous change
• ctrl + r will redo the previously undone change

• :tabnew FILE_NAME - open FILE_NAME in new tab
• :tabmove N - move tab to Nth position, if argument is not provided, moves tab to the last position

• vs filename - open in new vertical split
• sp filename - open in new horizontal split

Resizing:

• resize +5 to increase the height of the pane
• vertical resize +5 to increase the width of the pane

Alternatively, ctrl-w + and ctrl-w - to resize the height of the current window, ctrl+w > and ctrl+w < to resize the width of the current window. To resize all windows, ctrl-w =.

• \ c <SPACE> toggles commenting/uncomment of lines.

• Enter the command :/ (forward) or :? (backward), type in the search query, then hit to search. Hit to search for the next forward instance, and to search for the next backward instance
• :noh clears the highlighted search terms
• (Not specific to VIM, but helpful) Examples searching for files ending in ".erb" for the term "card-panel" - grep -R --include "*.erb" "card-panel" .
