Different exporters behave differently re exporter-specific lines

Different exporters behave differently re exporter-specific lines

I'm not sure how this feature is called, but in Org you can restrict a line
to a given exporter by prepending it with, eg, #+latex:

There's a bug with some exporters f treat these lines as paragraph breaks,
some don't.  For example, the following input:

Hello
#+latex: \TeX{}
World
#+html: Wide Web
!

Is exported to LaTeX as a single line, "Hello TeX World !", but to HTML
as separate paragraphs:

<p>
Hello
</p>
<p>
World
</p>
Wide Web
<p>
!
</p>

I wouldn't except these lines to introduce any paragraphs break.

This is with Emacs built from Git, using Org 9.2.6.

Best regards,
Thibault

This is not a bug in the exporters. The discrepancy exists in the output
languages, in particular in paragraphs. Org uses a definition of
a paragraph close to LaTeX's, so an Org paragraph isn't quite a HTML
paragraph.

I doubt it. There are 3 paragraphs, even for LaTeX, since there are
empty lines.

> as separate paragraphs:
>
> <p>
> Hello
> </p>
> <p>

Of course they should. You should look at the definition of a paragraph,
per Org syntax. Keywords cannot belong to a paragraph.

I believe there may have been a communication issue somewhere, since you
cite my message with extra \n --- there are no empty lines in my
original message.  For reference, here's the exact input I've used:
<https://paste.thb.lt/1572354712.org>.

The PDF output is at https://paste.thb.lt/test.pdf, the HTML output
here https://paste.thb.lt/test.html

As you can see, the LaTeX PDFs have everything in a single line, the
HTML output displays four separate paragraphs.

Thibault

This is because the definition of a paragraph in HTML, or LaTeX,isn't
the same as in Org. In this particular case, HTML matches Org
definition. LaTeX is more lax.

Thibault,

in case you might find this useful, you can use the @@ construct to put
things inline, causing less issues with paragraphs.  For instance, you
can write @@latex:\TeX{}@@.
