Hey, it's my talk, AMA :)

If you're interested in Elvish, you may also be interested in the talk on its design - https://www.youtube.com/watch?v=wrl9foNXdgM

Do you have a link to a copy of the video with captions? YouTube autogen doesn't cut it unfortunately. Or perhaps a written-form version (slide deck + transcript)?

What's in the 8% not covered by testing?

[xiaq]

I don't have a version with captions, sorry. You can find the slidedeck at https://github.com/elves/elvish/blob/master/website/slides/2...

The remaining 8% mostly falls into the following categories:

- Code that use OS functionalities that are cumbersome to mock in tests

- Code paths that are triggered relatively rarely and I was simply too lazy to add tests for them

Nothing is impossible to cover, but for whatever reason it was too much work for me when I wrote the code.

However, it's worth mentioning that I only settled on the transcript test pattern fairly recently, and if I were to rewrite or refactor some of the untested code today I would add tests for them, because the cost of adding tests has been lowered considerably. So Elvish's test coverage is still increasing slowly as the cost of testing decreases.

Hey, thanks again for the talk and for answering my fork bomb question with a live demo!

[xiaq]

Thanks for your question and glad that you enjoyed it!

In vim vi or nvim :r !date gives me shell returned 2

Did you set your login shell to Elvish? Vim unfortunately relies on your shell being a POSIX shell, but you can fix that with "set shell=/bin/sh" in your rc file.

Does elvish have a command history limit? Or is it configurable? I like a nearly infinite history.

[xiaq]

History entries are kept indefinitely.
