@DJMcMayhem How does the ascii code to char conversion work?

DJMcMayhem

17:39

@KritixiLithos A nice overview is here

Essentially, I replace every run of digits with <spaces><C-v><digits><more spaces>, and then run :%norm éiD@" which will add an 'i', delete it, and run it. Then typing <C-v><digit> in insert mode inserts ASCII characters

Kritixi Lithos

BTW, nice answer :)

DJMcMayhem

Thanks!

@KritixiLithos @nmjcman101 I posted a pretty in-depth explanation on my ASCII-table answer, if you're interested

Hmmm. I wonder if I should add a command for "run <motion> in insert mode"

Kritixi Lithos

Isn't there already a command in insert mode that allows you to do one normal mode command?

DJMcMayhem

Yeah, that's <C-o>

I meant a mapping to ii<esc>d<motion>@"

Maybe the "insert" part is irrelevant and I should make one for normal mode instead

btw, I've been trying to use the ê character in my submission (to remove the extra spaces after 100 to 127) but instead they delete the rest of the line

DJMcMayhem

@KritixiLithos what's the mnemonic on that one again? I can't remember what it's supposed to do

Kritixi Lithos

It does j forever

DJMcMayhem

Ah, that's right

I'll look into it later, I'm going to lunch now

Kritixi Lithos

Oh, bye o/

@nmjcman101 Now our answers are tied :)

@KritixiLithos I figured out the problem. Since the very last line of the buffer was empty, it moved the selection to the first column. You can see exactly what got selected if you add rg Try it online!

That's definitely expected and consistent. The question is if that's good.

If you have any good arguments against that behavior, I'd definitely be open to changing it

Kritixi Lithos

Ash, maybe I should move that bit after I remove those empty lines

DJMcMayhem

Anyway, if you delete blank lines first, it works fine. As a side note, ê is already a blockwise motion, so you can do dê instead of <C-v>êx

Try it online!

Kritixi Lithos

But doesn't dj delete the line below and not just the character that is underneath?

DJMcMayhem

Yeah. That's because j is a line wise motion by default

nmjcman101

That functionality replicated in dê would be useless since you can just do dG

DJMcMayhem

19:58

@KritixiLithos This is kind of an advanced feature, but every operator + motion combo affects either lines, characters or blocks. So you can do dvj, dVj, or d<C-v>j and they all work differently

Since j is already line wise, dj == dVj

Kritixi Lithos

@nmjcman101 But dG deletes the entire lines, I just want to delete the extra spaces after the three digit numbers

@DJMcMayhem what's the v do? (Can't use :h now since I'm on mobile)

DJMcMayhem

It specifies character wise

So dvj is exactly the same as vjd (and the same goes for V and <C-v>)

Once you're at a computer, the relevant help section is :h linewise
