luatex

luatex

[Thomas A. Schmitz]

Hi,

at the risk of sounding rude or impatient: I'd love to know when new  
releases of luatex and ConTeXt mkiv can be expected. The latest  
luatex trunk has some problems (no ligatures, hyphenation flaky) and  
doesn't work with some of my fonts. Latest ConTeXt beta only works  
with trunk of luatex. Hans mentioned some fundamental changes in  
luatex, so I was just wondering.

Thanks!

Thomas

What will a luatex based Context do for us that the current stable Context 
doesn't?

open type to start with, robustly grouped features, better and more 
robust spacing some day soon, more efficient and flexible xml, a new 
sectioning implementation, instant metapost processing (next year), and 
much more; eventually fundamental new features will only be written for 
luatex and pdftex (traditional tex) will be frozen.

In my further exploration I came across another product, toally unrelated, 
dealing with spreadsheets.  with the name of luatex.   Is the name luatex a 
trademark?  Lua is apparently. 

See:

  Yes, this was mentioned at the ConTeXt meeting last spring.  It's a
bit frustrating, sure, but ...

  Interestingly enough, this other luatex is to be parsed Lua / t / eX
because the last two letters stand for Excel.  And the normative
spelling is LuateX with an uppercase X :-)

  Not that I know of.  I don't think there would be any benefit to it,
though.  Recall that the name TEX itself---all uppercase---was a
trademark since a couple of years by the time TeX was created.  Who
remembers this typesetting system by the Honeywell company today?

Which is why "TeX" was never a real TM, just a "claimed" TM (according
to bnb, who should know).

Still luatex.com should have a pointer to luatex.org :-)

I think it's better don't mixed things.
For example:
Latex Allergy Support Group

Wikipedia can always help.

Hi,

For my particular case:
1. embed u3d models within a pdf without piping to an external script to 
compute the view (see http://www.nibua-r.org/ConTeXt/devel/new3dartwork/),
2. the ability to use lua script leads to potential interaction with 
MySQL (it could be great for me but I need to verify it's possible).
...

Cheers

luatex

[Hans Hagen]

Hi,

We're in the process of pushing a new luatex binary to the garden. It 
might be that context and luatex are out of sync (version checking 
stuff) but all will be well in a while.

Re: luatex

[Henri]

Are there any implications for the LuaJIT support?

LuaJIT is quite a bit faster than Lua which is why I always typeset my documents using luajittex.

Does the integer subtype give significant performance gains when you
can use integers instead of floats?

What are the main reasons for the switch?

luatex

[Hans Hagen]

Hi,

Luigi and I are currently looking into Lua 5.3 in combination with 
LuaTeX. We have an experimental setup and all seems to work well, which 
given the new number model of Lua is good news. Depending on how we 
compile the binaries we either gain some speed or in the worst case 
loose half the performance but that will be sorted out one of these days 
as we know where to look.

For most users the consequences will be minimal but for those who use a 
lot of Lua it makes sense to keep an eye on the subtle differences 
between 5.2 and 5.3 which is why I post this.

For TeXLive we don't expect the switch before 2019 (so 2018 will ship 
two binaries with the 5.2 one the official one) but for the context 
distribution we will make the switch earlier so that we can test in real 
situations.

Hans
