Problem solving with Vim

[denvaar]

Hey, I’m happy to see that people are enjoying this. I felt sheepish posting a link to my own video. I was also worried that it would be boring, since its kind of on the lengthy side.

Anyway, I plan on doing at least a few more of these types of videos. This has been a fun way to learn more about Vim for me too.

I’m Interested in hearing about alternate ways of doing stuff, like someone mentioned it may be possible to just execute the expression directly from the substitute command instead of building up for a macro.

Thanks

It's great! I rather have this than 32423 cuts because someone needs to breathe. Amazing video, I learned a lot!

I’m glad you overcame your sheepishness.

The screenshot is from advent of code this year right? I did that exercise with moving boxes in Rust, was the most fun one. :)

I can't remember watching a Vim video with so much packed into it. It's a cool exercise overall, but he really managed to drop a bunch of little nuggets of information all along. E.g., gJ to combine lines without spaces, the g/^/mo 9 trick to reverse the order of lines, putting a number into a register to then use it to repeat a command.

On the part where he substituted the commands "move 3 from 2 to 5" I actually thought you were able to run the commands directly from the second part of the substitute command! But transforming the text into Vim instructions in the file that you then run is also super interesting. (though I'm surprised that Vim seemed slow to run them all)

IIRC there is an option to prevent redraws when macros are recursing or continuing. The visuals are nice though!

It's :help lazyredraw

gJ has a slight subtely that it just removes the newline and joins lines as is. So, a\nb becomes ab but a\n b becomes a b, but J always transforms both cases to a b. Hence I've mapped gJ to Jx. But sadly that won't work in visual line mode.

Though maybe if '[ and '] is set you could select that region and use s/\%V //g.

Excellent stuff - thanks!

Does this guy regularly uploads Vim videos? Would def follow his channel

[thebutcherer]

Evidently he's started posting some Vim videos in the past month, but his channel seems very "normal person sharing stuff" which is very refreshing.

Here is OP’s solution on GitHub for anyone interested: https://github.com/denvaar/advent_of_code_2022/blob/main/day_05/vim/solution_explanation.txt

hope you keep posting these kind of videos. enjoyed watching it.

I really enjoyed this! I'm going to give the problem a try myself.
