Subtitle partitioning not working

[SandMann1]

My existing documents with subtitle partitioning, e.g = Main title:Subtitle now (beta 6) is tranlated to main title "Main title:Subtitle". Should be main title "Main title" and subtitle "Subtitle".

Can't find any other open issues or changelog notes related to this.

You seem to be missing a space after the separator, which is required.

= Main title: Subtitle

That has always been a requirement to my knowledge. It's also something that is handled by core, not by Asciidoctor PDF.

[mojavelinux]

The user manual states:

Note that a space is always appended to the value of the title-separator (making the default value of the title-separator effectively a single colon).

[PascalDutch]

I am also experiencing this issue, using = title: subtitle does not seem to work

[SandMann1]

Yes, you are correct. The example I gave was incorrect, my documents have this space. Why this was not working for my existing documents I am not sure. I suspect that maybe my build configuration at some point was changed so that :doctype: was article, not book. When :doctype: article the issue is still there, but perhaps more of an intended behavior. I'l close the issue as my problem is resolved.

[SandMann1]

Reopen as I just saw PascalDutch's comment. @PascalDutch I think the behavior is different related to :doctype: but I can't be sure if subtitle worked before when :doctype: article. Do you?

[PascalDutch]

I use :doctype: book and it is not working. I can't tell if it ever worked with :doctype: article since I have never used that type.

[SandMann1]

I can't find any documentation specifying the correlation between support for subtitle partitioning and doctype attribute. But as i said, it works for doctype book at my end now. Asciidoctor version 2.0.10 and asciidoctor-pdf 1.5.0 beta 6.

I suspect that maybe my build configuration at some point was changed so that :doctype: was article, not book.

The default doctype in Asciidoctor PDF has always been article (as it is for all converters). The difference is that the article doctype is now fully respected, which means the title joins the first page of the body instead of on a separate page.

I can't find any documentation specifying the correlation between support for subtitle partitioning and doctype attribute.

Subtitle partitioning is only supported in Asciidoctor PDF when the title page is used (either the doctype is book or the title-page attribute is set).

When :doctype: article the issue is still there, but perhaps more of an intended behavior.

As of now, that is by design. If you'd like subtitle partitioning to work for the article doctype, please open a separate issue with that subject.

[mojavelinux]

I use :doctype: book and it is not working.

I don't believe this to be true as we have tests that verify it does work. Please provide a complete example so that we can determine if there's a use case being overlooked by the test suite.

The subtitle is not working because you are overriding the title using:

:title: SomeTitle

Take that away and it will work.

[PascalDutch]

It works, such a simple fix. Thanks for the support!

[mojavelinux]

Excellent!
