Learnings for Week 17 2010

Learnings for the past week.

• vim (I made the switch this week!)
  • ctrl+v to enter visual mode (useful for block comments)
  • :sp to split a window
  • :vsp for vertical split
  • :A for alternate file (rails plugin)
  • snipmate for awesome snippets (plugin, snippets)
  • * searches for current word
  • :%s/search/replace/modifiers
    • if you leave search blank it uses your previous search
    • g modifier for global search, c to confirm each replacement (very useful!)
• autotest doesn’t run in ruby 1.9.1
  • It fails for me saying “set a breakpoint in malloc_error_break to debug” and that’s about all
• ruby -e “code to run”
• assert_select(‘input’, 0) doesn’t work, need to use (assert_select ‘input’, :count=>0)
  • This is confusing since assert_select(‘input’, 5) works just fine

That’s it for this week. If I find some time I’ll post my vim config and talk about that a bit and maybe discuss what I did about autotest not working.
