Does VHS have a way to add commands?

I do like the concept but one charming feature of asciinema is it captures natural input hesitation, typing candence, deletions and fixing mistakes, etc. The VHS tape replay seems so artifical.

I could see how to fake it with the current commands, but I could imagine a "HumanType" or something which increases the delay variance or includes typos that are backspaced and fixed etc, automatically.

Just a quick ponder.

I was looking at the code, and it seems like you could put a low value for this and it would do what you want.

I did not try it though

  // sleepThreshold is the time at which if there has been no activity in the
  // tape file we insert a Sleep command
  const sleepThreshold = 500 * time.Millisecond

EDIT:

I tested it. It actually work, but their software crash, I had to patch line 153

  for lines[i] == lines[i+repeat] {
    repeat++
    if i+repeat == len(lines) {
      break
    }
  }

EDIT 2:

I actually went ahead and created a pull request to fix the bug.

I think it'll cover your needs. You can configure typing speeds, send commands for backspacing, if you were driving vim you could obv record doing search/replace/deletions

The fact you can iterate at all is its appeal to me

I saw that, yeah, but I don't want to do that manually.

A custom command that could add some jitter automatically or just pretend to be a bit more human would be nice.

Lets type "ls -lap" with some hesitation and a typo...

  Type "ls "
  Sleep 200
  Type "-"
  Sleep 300
  Type "l"
  Sleep 50
  Type "aa"
  Sleep 100
  Backspace
  Sleep 150
  Type "p"
  Enter

:(

There is the TypingSpeed variable but its not exactly what I'm going for.

I appreciate and use asciinema, but a big plus one for VHS.

I like being able to store my tapes in a repo and edit them:

And as the official VHS docs show you can do even more interesting things with CI/CD

The charmbracelet team is rocking the command line with Go.

Surprised no one has mentioned the big difference in that you can copy paste from asciinema animations but not from a vhs gif. At least last I looked it was like that.

VHS interesting, because you declaratively specify what you are recording and version control it.

However, I quickly hit a painful limitation, viz.: if a command takes non-trivial amount of time to run, you need to hack it by using `Sleep` to wait for command output. So I'm not fully convinced to switch from asciinema.
