1 00:00:00,000 --> 00:00:03,436 Hi! Welcome back to Emacs rocks! 2 00:00:03,436 --> 00:00:08,125 It's episode 2 and today I have a real treat for you. Check it out! 3 00:00:08,125 --> 00:00:10,562 It's VimGolf! Yay! 4 00:00:11,900 --> 00:00:15,925 VimGolf is really cool, I really wish there was one for Emacs. 5 00:00:17,292 --> 00:00:21,371 It's a competition and the goal is to transform 6 00:00:21,387 --> 00:00:23,662 the starting file into the ending file 7 00:00:23,662 --> 00:00:26,800 in as few keystrokes as possible. 8 00:00:29,508 --> 00:00:33,244 So, this is challenge number 6 and 9 00:00:33,244 --> 00:00:39,152 there is a one to ten in letters and a one to ten in numbers 10 00:00:39,152 --> 00:00:43,923 and the goal is to get the one to ten lined up in two columns. 11 00:00:45,382 --> 00:00:49,790 So the best score into Vim is 17, is the winning score. 12 00:00:51,052 --> 00:00:54,233 So let's see if Emacs might do a little bit better. 13 00:01:12,833 --> 00:01:17,005 Ok, I'll run through it one time without commentary 14 00:01:17,021 --> 00:01:20,259 and then I'll run through it again and tell you what I'm doing. 15 00:01:20,259 --> 00:01:22,789 So pay attention to the keystrokes. 16 00:01:46,000 --> 00:01:49,825 Haha! Now wasn't that awesome. 17 00:01:50,008 --> 00:01:53,167 Let's see it again in slow motion. 18 00:02:01,621 --> 00:02:04,246 Ok, now we are back to the start. 19 00:02:04,938 --> 00:02:09,282 This is the first episode where I use macros but it won't be the last! 20 00:02:09,282 --> 00:02:12,413 Macros is a powerhorse in Emacs. 21 00:02:12,413 --> 00:02:15,656 So I start by defining a macro pressing F3 22 00:02:15,656 --> 00:02:21,887 then jump to the bottom and I delete all. 23 00:02:22,385 --> 00:02:27,429 This puts it into the kill ring and I erase the space 24 00:02:27,429 --> 00:02:30,136 and then I press Control-9 25 00:02:30,136 --> 00:02:32,690 Control-9 doesn't do anything on it's own, 26 00:02:32,690 --> 00:02:35,675 but it makes my next command repeat 9 times. 27 00:02:36,775 --> 00:02:41,931 Which is command p for previous line, 9 lines up 28 00:02:42,498 --> 00:02:48,579 Control-E, tab, yank, and my macro is finished. 29 00:02:48,579 --> 00:02:52,175 So I press F4 to complete my macro and now 30 00:02:52,175 --> 00:02:57,631 I can run that macro nine times, Control-9 F4. 31 00:02:58,467 --> 00:03:00,105 Done. 32 00:03:00,105 --> 00:03:03,008 And that was 12 keystrokes. 33 00:03:03,008 --> 00:03:06,748 Let me remind tou, best in Vim, 17. 34 00:03:07,485 --> 00:03:09,944 So, to reiterate 35 00:03:11,621 --> 00:03:14,525 Emacs rocks!
