LuaTeX 64bit

LuaTeX 64bit

Hi guys,
I don't think I have ever needed more than than 3-4gb, so it worth using the
64bit ver. of LuaTeX?  Can I force the minimals install script to download
and use the 32bit binary instead?

I'm on a 64bit machine and I'm sure that on linux I can run that app in
32bit mode.

What would be the advantages of using the 32-bit version?

You need to desable automatic format generation and you need to pass
--platform=linux as argument to mtx-update.lua in first-setup.sh ...
then you need a costum version of setuptex (or you can set path
manually) that will set the path to linux instead of linux-64.

But I have no idea why you would want to do that.

One more question, how do I only create the formats for British English 
only?  No Dutch, American English etc..   I'm going to argue on the list 
that the en_GB should be the default ;), but I'll save that for another day.

There is only one English format that you can generate with "texexec
--make en". If you're speaking about how to generate only that one
with first-setup.sh, then you should be, at least in theory, able to
generate only the chosen formats with --formats switch or my modifying
the lua file that gets generated, but I imagine that it doesn't work
or at least I have never tested it so far.

Yes, it only downloads the modified files, but it doesn't use
checksums since using them is much slower. You could add an additional
-c switch, but you will not notice any difference (apart from a few
files that Hans recreates every time when he uploads a new zip, but
that's neglectable). Rsync checks for date+size. Only if these two are
different it fetches the file. You could add checksum checking, but I
guess that you don't gain anything.

The only critical component where I really do need to change this are
luatex and metapost source, but this only concerns binary builders,
not users.

I forgot to finish the sentence. You can use British hyphenation rules
instead of American ones with \mainlanguage[ukenglish]. And no, the
behaviour is not going to change.

TeX uses Knuth's hyphenation rules as well. ConTeXt uses slightly
improved ones. Differences are almost neglectable anyway.

there has been a time that this was possible, but inpractice it's not 
that handy ... specifying the language should be part of the document 
preamble; in that time we had no gyre and as language is related to 
patterns + font encodings in mkii it was even more tricky

one thing that you can do is add \mainlanguage[gb] to cont-sys.tex 
default to brittish english so that on your system it always starts that 
way; the overhead is nil
