Description

What

Nightly now includes the ability to display extmarks on wrapped lines. This feature has made its way into other indent guide plugins (see here and here).

How

Using nightly, seeing the effects of this feature only requires placing virt_text_repeat_linebreak = true into the extmark_opts table in indentscope's make_draw_function(). In the below example, I am using indentscope with this option on, and it is visible on the wrapped lines indicated by dashes in the number columns.

The bulk of the change seems like it would be adding error handling and checking the user's Neovim version (until 0.10 is released), options, and indentscope configuration.

Thanks for the suggestion!

I've just checked it, and it indeed seems to work with one line change.

As the feature is only a week old, I'd wait a bit until it is more polished. Then add it behind a version check.

This should be resolved on latest main thanks to @gpanders.
