2. BEYOND THE BASICS SOME ASSEMBLY REQUIRED
3. OVERVIEW • documentation • quickfix • ctags • marks
4. DOCUMENTATION
5. DOCUMENTATION: MAN K
6. DOCUMENTATION: VIM autocmd FileType vim setlocal keywordprg=:help
7. DOCUMENTATION: RUBY autocmd FileType ruby setlocal keywordprg=ri
8. QUICKFIX
9. :help quickfix In vim the quickfix commands are used more generally to find a list of positions in files.
10. :help location-list A location list is similar to a quickfix list and contains a list of positions in files.
 … A location list is associated with a window and each window can have a separate location list.
 … The location list is independent of the quickfix list.
11. QUICKFIX: MAPPINGS map <leader>cn :cnext<cr> map <leader>cp :cprev<cr> map <leader>co :copen<cr> map <leader>cc :ccl<cr>
12. QUICKFIX: INSTALL GREP • brew tap homebrew/dupes • brew install —with-default-names grep
13. QUICKFIX: SEARCH RESULTS nmap fw :grep -r <cword> . <cr>
14. QUICKFIX: SYNTAX ERRORS autocmd FileType ruby nmap <buffer> <leader>sc 
 :cexpr system (‘ruby -c ‘ . bufname(“%”))<cr>
15. QUICKFIX: LINTERS autocmd FileType ruby nmap <buffer> <leader>li 
 :cexpr system (‘rubocop ‘ . bufname(“%”))<cr>
16. QUICKFIX: TESTS autocmd FileType ruby nmap <buffer> <leader>tf 
 :cexpr system (‘rspec 
 -r ./spec/support/quickfix_formatter.rb 
 —format RSpec::Core::Formatters::QuickfixFormatter ’ 
 . bufname(“%”))<cr>
17. QUICKFIX: TESTS require 'rspec/core/formatters/base_text_formatter' module RSpec module Core module Formatters class QuickfixFormatter < BaseTextFormatter RSpec::Core::Formatters.register self, :example_failed def initialize(output) @output = output end def example_failed(notification) @output << format(notification) + "\n" end def format(notification) fmt = "%s: %s" % [notification.example.location, notification.exception.message] fmt.gsub("\n", ' ')[0,160] end end end end end http://git.io/vCwCw
18. QUICKFIX: LOGGING Integrating with Quickfix
19. CTAGS
20. CTAGS: INSTALL brew install ctags
21. :help tags A tag is an identifier that appears in a “tags” file. It is a sort of label that can be jumped to. … The “tags” file has to be generated by a program like ctags, before the tag commands can be used. CTAGS
22. CTAGS: MAPPINGS set tags=.ctags;$HOME nmap <leader>tt :execute “!ctags -R -f ./.ctags .”<cr> nmap gd <C-]> nmap gb <C-t>
