Hello LuaTeX developers,
I have a few questions I'd like to ask you. In log message, luatex
engine produces slightly different error context from what pdftex does.
Here is a sample code:
----------------------------------------------------------------------
Nullam eu ante vel est convallis dignissim. } Nulla posuere.
\bye
----------------------------------------------------------------------
When I process this file by luatex, it results in the following error:
------ luatex result -------------------------------------------------
! Too many }'s.
l.1 Nullam eu ante vel est convallis dignissim. }
Nulla posuere.
----------------------------------------------------------------------
On the other hand, pdftex results in:
------ pdftex result -------------------------------------------------
! Too many }'s.
l.1 Nullam eu ante vel est convallis dignissim. }
Nulla posuere.
----------------------------------------------------------------------
The output of luatex is shifted by two characters compared with that of
pdftex. (I'm using TeX Live 2021.)
This discrepancy confuses preview-latex (subsystem of AUCTeX), which
depends on the precise position of the log messages:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=54200
I'm not sure whether this behavior is a bug or not, but is it something
I can expect to be fixed? If not, is there any workaround to make the
output the same as pdftex? (e.g. command line option)
Regards,
Ikumi Keita
