List of killed text sequences.

Since the kill ring is supposed to interact nicely with cut-and-paste
facilities offered by window systems, use of this variable should
interact nicely with interprogram-cut-function and
interprogram-paste-function. The functions kill-new,
kill-append, and current-kill are supposed to implement this
interaction; you may want to use them instead of manipulating the kill
ring directly.

Thank you

It's weird, it works again, but I don't know why it hangs a long time and without responding

[kaushalmodi]

Hello,

It looks like you are using the development version of Org mode installed from its git repo.

1. If you haven't updated Org mode in a while, please do the update and then check if that issue is still there.
2. If the issue is still there, see if this workaround helps: Post exports hang or take a very long time when single org file gets large #551 (comment).

If the above workaround works for you too, let me know. We can close this issue and continue the discussion in #551.

[kaushalmodi]

I tried using your example post and exporting it .. and it finished in 0.52 seconds

[ox-hugo] Exporting ‘网络安全’ (test.org)
Wrote /home/kmodi/stow/pub_dotfiles/emacs/dot-emacs.d/elisp/ox-hugo/test/site/content/posts/test.md
exec time: 0.517660107

Unfortunately, if this is the issue caused due to org-element caching enabled on the Org built from the main branch, that issue is difficult to reproduce.

[yufengwang]

Thank you very much, I'll dig deeper next time it hangs there. At least it works again now.
