emergency stretch not taken in account in some cases

emergency stretch not taken in account in some cases

[-- Attachment #1.1: Type: text/plain, Size: 619 bytes --]

Dear all,


In some cases specifying \setupalign[stretch] does not seem to have any effect with latest betas (live, 2016.06.20 22:14 version are fine, but 2016.07.18 is not), and the output has now overfulls instead of (admitedly a bit large) underfulls.


Attached  simple (albeit bit extreme) MWE. Sorry for the relatively large MWE but could not figure out how to make it shorter.


emergency_stretch.pdf produced with latest beta (updated with first-setup.bat today).

emergency_stretch_ok.pdf produced with 2016.06.20 22:14 version.


Thanks a lot for any advise.


Best regards


Joseph Canedo

I can’t reproduce your problem but justified text isn’t the best option 
in narrow columns.

Below is a simplified version of your code which doesn’t use the parent 
setting from margindata and marginframed setups, there is also no need 
to set the alignment twice and marginframed has no method key (the 
source is wrong).

\definemargindata
   [InOuter]
   [method=first,
    location=outer,
    margin=margin,
    width=\outermarginwidth,
    style=\tf,
    stack=continue,
    align={normal,hanging,morehyphenation,hz,verytolerant,stretch}]

\definemargindata
   [InInner]
   [method=first,
    location=inner,
    margin=margin,
    width=\innermarginwidth,
    style=\tf,
    align=outer]

\definemarginframed[InOuter]
\definemarginframed[InInner]

%\setuplayout[width=12cm,rightmargin=4cm]

\starttext

Foo \InOuter{\input knuth } Bar.

Thanks a lot Wolfgang for the simpler code, I’ll replace mine with your suggestion, in actual document the margins width are much larger and font smaller too.

I use binaries on Win64 platform (installed using command line method: first-setup.bat --modules=all):


$ ls -l $(which luatex.dll)
-rwxr-xr-x 1 Jo Administrateurs 9567232 Jul 11 22:29 /c/ConTeXt/test/tex/texmf-win64/bin/luatex.dll 


$ luatex --version
This is LuaTeX, Version 0.97.0 (TeX Live 2016/W32TeX)


$ context --version
mtx-context     | current version: 2016.07.18 16:46

I think I could figure out the reason of this problem. Actually emergency stretch is broken in all cases it seems. In luatex source code I see:


source/texk/web2c/luatexdir/tex/commands.w:    primitive_tex("emergencystretch",
 assign_dimen_cmd, dimen_base + emergency_stretch_code, dimen_base);


source/texk/web2c/luatexdir/tex/equivalents.h:#define emergency_stretch_par
         glue_par(emergency_stretch_code)


source/texk/web2c/luatexdir/tex/equivalents.h:#  define glue_par(A)  equiv(glue_base+(A))


I could be wrong but to me it seems we assign some value to emergency stretch “variable” setting using “emergencystretch” command and we use another via emergency_stretch_par.


Unfortunately I am not able to build luatex locally on Windows Platform, only sync code from SVN repository.


Thanks a lot,


Joseph Canedo

This produces three different paragraphs.
