Ending strings with non-break space in lang-txt.lua

Ending strings with non-break space in lang-txt.lua

[Marco Patzer]

Hi!

I've got a few unfortunate line breaks in my documents. In particular, breaks
are introduced in between the string “page” and the number:

  See figure 1 at page
  2.

The reason is that many strings in lang-txt.lua end in a space, rather than a
non-break space:

  ["atpage"]={
   ["labels"]={
    …
    ["en"]="at page ",
    …

I fixed this by defining

  \setuplabeltext
    [en]
    [atpage=at page\nbsp]

So I wonder: Does it ever make sense to have a regular space at the end of
those commands? I just skimmed through the file and most, if not all, strings
ending in a space would actually benefit from having it replaced by a
non-break space IMO.

Example:

\def\pageref#1%%
  {\in{figure}[#1] \labeltext{atpage}\at[#1]}

\starttext
  \hsize 3cm
  See \pageref{foo}.

  \page \startplacefigure [reference=foo] \stopplacefigure
\stoptext

I agree, it drives me
nuts to see p.
5 or in Figure
8 etc.


Also, how about:

\at{\labeltext{atpage}}[#1]

(and does this make the space in the label redundant?)
In any case it is a bit sloppy...

indeed, that is the command to use

can you experiment with this

\unexpanded\def\leftofreferencecontent
   {\removeunwantedspaces
    \nobreakspace
    \ignorespaces}

Don't get too hung up on that command. That was just a quick way to
demonstrate the point and create an MWE.

This fixes the MWE, but it doesn't prevent all "unfortunate" line
breaks caused by the spaces. At least it doesn't if \labeltext is
used separately to obtain the translated strings.

Currently I use (in one of my modules):

  \def\foo{\labeltext\v!atpage\currentreferencepage}

This works (as by your suggestion):

  \def\foo{\labeltext\v!atpage
    \removeunwantedspaces\nobreakspace\ignorespaces
    \currentreferencepage}

Which basically replaces the space with a non-break space after the
fact.

So I wonder if it's not a better solution to fix the initial
definitions. But I might be mistaken or I'm overlooking something
where this might cause issues.

it then interferes with mechanisms that inject spaces themselves (as 
\at{...}[]

(i'll add am auto check space and replace by nonbreak space trick)
