replacement of "\@." ?

replacement of "\@." ?

[Ryo Furue]

Hi ConTeXt users,

I'm wondering what's the ConTeXt version
of LaTeX's "\@."  (which indicates an end-of-sentence
period).  I can define

  \def\@{\spacefactor1000}

and use it, but if there is an official version
I'd like to know.

Regards,
Ryo

I think in Professional typesetting, the same amount of space should
be left for all full stop/comma/whaever.
You'd better change TeX's default behavior.

huh?

each language can has its own rules ... spacing after period or comma is 
one, but also think of quotes in quotations etc; and, the french have 
spacing before and after : ; . , (it has always been a selling point for 
tex to be able to deal with it)

Not only French, it is also the case for traditional Arabic typesetting,
though people tend to follow the English rules these days.

Thanks, but that doesn't change the spacing, in my environment
at least.  (I use texlive-context on the testing distribution
of Debian.)

I think the command "\ " inserts an inter-word spacing,
not an inter-sentence spacing.  You can compare whether

   USA.\ This is another sentence

gives the same result as

   USA\spacefactor1000. This is another sentence

I know there is a typographic style where the inter-word
and inter-sentence spacings are the same.  But, by default,
ConTeXt uses a larger inter-sentence spacing than the
inter-word spacing.  In such a case, there has to be a means
to indicate an inter-sentence spacing when a sentence ends
with a capital letter and a period.

Regards,
Ryo

The TeXbook suggest to use \null before the period,
e.g. "USA\null. This is another sentence" but I would prefer
here LaTeX's \@.

@Hans: There is something wrong with \nonfrenchspacing (or  
spacefactor) in mkiv.

\starttext

USA. This is another sentence

USA.\ This is another sentence

USA\null. This is another sentence

USA\spacefactor1000. This is another sentence

\stoptext

Another test file, as you can see (ConTeXt and Hans extended plain  
TeX) it happens
only with OT fonts but not with Type1.

\font\one=cmr10
\font\two=file:texgyrepagella-regular
