Erik Schwartz -- Environment Improvements 1

Environment Improvements May 2 - May 9, 2014

As I write software I jot down minor annoyances in the development workflow or things I’d like to generally understand better. Each morning I spend 20 minutes addressing one or two problems and capture my new learnings here for posterity.

Vim: Editing Macros

C-r C-r a inserts register a in command mode
* register is system clipboard

Vim: make temporary key mapping to run a script you’re debugging

map <leader>r :!spring rake db:seed<cr>

Vim: Copy filename to system clipboard

:let @* = expand("%") from Stack Overflow
To map a keystroke :nmap cp :let @* = expand("%")

Vim: Ignore .keep files from ctrl-p file search

let g:ctrlp_custom_ignore = '.keep\|node_modules\|DS_Store\|git\|tmp/cache\|.swp'

Vim: delete text within html tag

dit who knew?!

Vim: tab refresher for easily looking at gem source code

	tabe          create new tab
	gt            go to next tab
	gT            go to previous tab
	{i}gt         go to tab in position i

Vim: prompt to mkdir if doesn’t exist

augroup vimrc-auto-mkdir
  autocmd!
  autocmd BufWritePre * call s:auto_mkdir(expand('<afile>:p:h'), v:cmdbang)
  function! s:auto_mkdir(dir, force)
    if !isdirectory(a:dir)
          \   && (a:force
          \       || input("'" . a:dir . "' does not exist. Create? [y/N]") =~? '^y\%[es]$')
      call mkdir(iconv(a:dir, &encoding, &termencoding), 'p')
    endif
  endfunction
augroup END

Bash: Use cut remove leading whitespace

Useful for removing extraneous stuff before piping output to another command

$ git branch
   foo-branch
$ git branch | cut -c 3-
foo-branch

Bash: Movement by words (like emacs)

M-f forward
M-b backward

deploy non-master branch to heroku (aka use standard git to push a feature branch to heroku master)

g push heroku search-park-name:master

Binstubs

Prepare the environment before shelling out to an executable
In practice this means the script makes sure the executable runs against the project’s ruby version and gemset
