panic: reached end of file before reaching end identifier

[aidalgol]

I'm trying to use termshot to capture Nushell output, and it panics.

❯ ./result/bin/termshot nu

❯ ls

This is with v0.2.5 of termshot.

Just ran into the same thing.

same issue I ran termshot /bin/zsh to begin the capture sequence

At least in my case, the error is caused by having OSC8 hyperlinks in the output stream.

One way to reliably cause this failure is to use eza:

# this works fine, without hyperlinks:
$ termshot -c -- eza            
bin  dist  git-ls  go.mod  LICENSE  main.go  Makefile  out.png  README.md  static

# this doesn't, with hyperlinks:
$ termshot -c -- eza --hyperlink                                                             
bin  dist  git-ls  go.mod  LICENSE  main.go  Makefile  out.png  README.md  static

I was finally able to reliably reproduce the issue locally. In my case, it was due to bunt only checking for the BEL as the terminator, but the ST is also being used in some use cases. So this might also solve the issue with the examples here. If not, feel free to reopen the issue. Fix is in release https://github.com/homeport/termshot/releases/tag/v0.4.1.
