Skip these steps and delete the Plugin 'powerline/powerline' line if you have already had your powerline installed, and don't forget to set the powerline rtp by set rtp+=/PATH/TO/YOUR/POWERLINE/LIBRARY/bindings/vim.

1. Install fonts from https://github.com/powerline/fonts.

$ git clone https://github.com/powerline/fonts /tmp/fonts

Skip these steps and delete the Plugin 'fatih/vim-go' line if you don't need to play with Golang.

1. Install Golang tool chain.

$ sudo pacman -Syu go

2. Install Golang helpers.

Recommend install the silver searcher and fd to accelerate :Find and :Grep commands.

Usage

• :Grep PATTERN to search PATTERN in all files under current working directory, auto jump to the first result, and open the location list. The results are stored in the location list, see :h :lfile.
  • By default, the command only match a whole word, that is, PATTERN should be surrounded by non-word characters or start/end of line.
  • :Grep PATTERN i for case non-sensitive
  • :Grep PATTERN w for searching part of a word
  • :Grep PATTERN h for searching only in files with suffix ".h"
  • Multiple parameters are available, e.g., :Grep PATTERN iwh (order doesn't matter)
• :Find PATTERN to search files whose path matches PATTERN. :Find PATTERN d for searching directory. Since it searches "path", '/' is valid in PATTERN.
  • It searches case non-secsitively, and some regular expression are valid. For example, :Find test_dir/.*\.py matches the files under test_dir (recursively) and ends with ".py".
• Y is mapped to y$ to match the behavior of D.
• F3 in Normal mode to search the word under cursor recursively from current working directory.
• F3 in Visual mode to search the select string.
• F4 in Visual mode to mark the first exchange target, and one more time in Visual mode to perform exchange. See here for what is exchange.
• F4 in Normal mode to unmark.
• F5 in Normal mode to toggle NERDTree
• F6 in Normal mode to toggle tagbar

YCM

• In insert mode, the arrow keys UP/DOWN are mapped to selecting the prev/next condidates. This helped me a lot to get used to keeping working in Normal mode instead of staying in Insert mode.
• Function key F7 is mapped to "show documentation".

Ultisnips

• Press tab key to trigger and forward, shift-tab to backward. See here for what is Ultisnips.
