Here’s a pretty hard challenge—at least I found it challenging. Given this Lorem Ipsum
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.
list the unique, capitalized words in alphabetical order:
Accusam Aliquyam Amet At Clita Consetetur Diam Dolor Dolore Dolores Duo Ea Eirmod Elitr Eos Erat Est Et Gubergren Invidunt Ipsum Justo Kasd Labore Lorem Magna No Nonumy Rebum Sadipscing Sanctus Sea Sed Sit Stet Takimata Tempor Ut Vero Voluptua
The winning Vim solutions use 23 keystrokes but the best I can do is 32. My solution:
| 【Ctrl+Meta+%】 | Invoke query-replace-regexp |
| 【space Return】 | Replace spaces |
| 【Ctrl+q Ctrl+j Return】 | With carriage returns |
| 【!】 | In the entire buffer |
| 【Meta+<】 | Back to top-of-buffer |
| 【Ctrl+Meta+%】 | Invoke query-replace-regexp |
[.,] 【Return】 |
Replace periods and commas |
| 【Return】 | With nothing |
| 【!】 | In the entire buffer |
| 【Return】 | Down one line |
| 【Ctrl+Return】 | Invoke rectangle mode |
| 【Meta+<】 | Extend rectangle to top-of-buffer |
| 【Meta+u】 | Upcase rectangle |
| 【Ctrl+x h】 | Mark buffer |
| 【Ctrl+u Meta+|】 | Pipe to shell and replace |
sort -u 【Return】 |
Sort and delete duplicates |
Most of the work involved the two query-replace-regexp calls but I couldn’t figure out a way to do it in one without causing other problems. The call to the external sort may be a technical violation but I’m claiming that we’re grandfathered in by Tim on that.
I think the Vimers did so well because Vim has an internal sort that’s easy to invoke. I’m sure many of you can beat my pathetic 32 so leave a comment with your better solutions.
