Emacs doesn't hide the period. But there shouldn't be a period to begin with, since it's the middle of a sentence. The correct way of writing this in Texinfo is to have some punctuation: a comma or a semi-colon, after the closing brace, like this: This is the warning level of @ref{e,,-Wshift-overflow3}, and … Does Sphinx somehow generate the period if there's no comma, or does it do it unconditionally, i.e. even if there is a punctuation after the closing brace? > > This actually raises a more general issue with this Sphinx porting > > initiative: what will be the canonical style guide for maintaining the > > GCC manual in Sphinx, or more generally for writing GNU manuals in > > Sphinx?

Did you compare the style conventions there with what we have in the Texinfo manual? Moreover, this means people who contribute to other manuals will now have to learn two different styles, no?

See e.g. the Linux kernel documentation: > https://www.kernel.org/doc/html/latest/ I don't think the GCC manuals should necessarily be bound by the Sphinx standards. Where those standards are sub-optimal, it is perfectly okay for GCC (and other projects) to deviate. GCC and other GNU manuals used a certain style and convention for decades, so there's more than enough experience and tradition to build on. I will no longer pursue this point, but let me just say that I consider it a mistake to throw away all the experience collected using Texinfo just because Sphinx folks have other traditions and conventions. It might be throwing the baby with the bathwater.
