Summary0000544: ! No room for a new \write
DescriptionDear developers,

I gave LuaLaTeX on an actual MiKTeX a try [Version beta-0.60.2-2010100221 (MiKTeX 2.9) (rev 3736)] and ran into problems I also have when I use pdflatex. Running the attached dummy minimal gives

! No room for a new \write .
\alloc@ ...else \errmessage {No room for a new 0000002}
                                                  \fi \fi
l.48 \begin{document}

Commenting one or more of the marked lines (% <--) shits the error message until if finally fanishes when all the marked lines are commented.

Could the number of writes be enlarged?

Best regards,
Stefan Pinnow
Steps To ReproduceJust run lualatex on the provided minimal.tex file.
TagsNo tags attached.

I tried to patch LuaTeX to allow more write streams, but the number 16 is hard-coded at various distant places in the code, so that would be a major undertaking. The better solution is to patch LaTeX packages to use use Lua (which has no hard limits) if it is available.

Joseph has just written a blog post about write streams:

Markus Kohm claims to have written a package that reduces the number of needed write streams. It is not public yet, but you can ask him to let you test it:

We won't be fixing this until we reach the point where all internal limits will be removed
