But normally there should be very few messages,
as message and show should be used with parsimony...
(Indeed there are very few in the standard metapost and metafun macros)
Maybe in ConTeXt we should have a distinction in allowing
the turning on of one or the other (show, message and errmessage).

There is always `context --noconsole` if you want to omit the messages. I
think that it is a good idea to display messages by default, or better
still, the logging and tracing macros of metapost and tex be enabled by a
common interface.

It solves the problem, thanks.
I find another problem with the example in my previous email. I changed the
example a little bit.
Example:
\startuseMPgraphic{mpos:par:columnset:textuline}
\iftracepositions show_multi_pars \else draw_multi_pars \fi ;
path p ; p := boundingbox currentpicture ;
currentpicture := currentpicture shifted (0,0.3*StrutDepth) ;
setbounds currentpicture to p ;
\stopuseMPgraphic
\definetextbackground
[underline]
[location=text,

mp=mpos:par:columnset:textuline,
background=,
frame=off]
\starttext
\underline{blurblur}
\underline{blurblur}
\underline{blurblur}
\underline{blurblur}

The vertical positions of underlines are not stable. See the attached PDF file.

OK. It could be nice then to simply state this?

Thanks a lot for these. With these hints I am now able to compile
metapost figs from conTeXt through texexec --luatex normaly.
To this end, I had to perform two tweaks:
* the files mlib-run.lua, mlib-ctx.lua, and mlib-pdf.lua were *NEVER*
loaded so I added to my conTeXt source file:
\directlua0 { dofile
(/usr/share/texmf/tex/context/base/mlib-ctx.lua) }
\directlua0 { dofile
(/usr/share/texmf/tex/context/base/mlib-run.lua) }
\directlua0 { dofile
(/usr/share/texmf/tex/context/base/mlib-pdf.lua) }
* the format was generated correctly but loaded incorrectly:
I had to add the following line:
ini_version = false,
in the metapost.load function in the mlib-run.lua file.
Now everything is OK. The second thing (an misfortunate typo) is easy
to fix. However, the fact that mlib-*.lua are never loaded is more worrying:
any idea where this error comes from?
Hope this will help Hans as well.
Cheers,
Olivier

This should be fixable by simply updating your context, because that
is already fixed in newer contexts. But this could well be the cause
of Hans' problems.

All ok, I didn't meant that you must switch to minimals . In Ubuntu I have put minimals under /opt/luatex/minimals (and minimals-beta in /opt/luatex/minimals-beta) . They are unrelated with package system, texlive2007, texlive2008 and so on ; also installing/updating minimals is easy (at least on ubuntu) apart luatex version (but it's not really a problem) . I run every tests under minimals and minimals-beta . If they work, I assume minimals / minimals-beta are OK . Your test works on my minimals, so (my) minimals are OK. So if you install minimals /minimals-beta you can even say what is wrong in your packaging (if something is wrong: maybe you have mixed files) . I feel good with ubuntu, but for TeX related stuff I prefear manual installation . I don't expect that anyone agree on this . -- luigi ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

I played a bit with pdfluatex directly which seems to work. (I'm not to the point of producing figures, because I would have to rebuild all the functions that are located in mlib-run.lua and the luatexref-t.tex does not give straightforward example of how the mplib module should be used, it only describes the functions API. Btw: could you add in the doc a simple example of how to set up an mplib instance (loading the format file) and typesetting a minimal graphic, and then use it from within plain TeX for instance; this is transparent to conTeXt users since there are files like mlib-run.lua but not easy for plain TeX users :P And I'm not advocating the use of plain TeX, I'm a converted conTeXt user since 2003, but this will help user understand (a bit) how things work behind the scene.)

Re: [NTG-context] mplib errors

If you are also working on MacOSX(10.5.x) then I should expect the problem to be platform specific. I had some discussions with Taco Hoekwater about this problem, but we never solved it and I have no inkling of its cause. Since I am not well enough acquainted with the code behind mplib and friends, I had to fall back on using MKII and putting MKIV aside. But I guess the solution to this problem is pressing, since we cannot have one platform falling out on ConTeXt.

Hi Taco, I did kpsewhich mp-tool.mp and it came up with /usr/local/texlive/ 2007/texmf-context/metapost/context/base/mp-tool.mp. That file has in my system creation+modification date 01-04-08 02:14 and was last opened 03-07-08 so this must be it. Came straight from unpacking the context distribution zip. This should have been cont-tmf.zip created 05-08-08 17:13. The other mp-tool.mp in my system is /usr/local/texlive/2007/texmf- dist/metapost/context/base/mp-tool.mp. I also checked this one and found it has creation+modification date 06-02-08 12:52 and was last opened 06-02-08 12:52. So this one was apparently never used by me after installing texlive2007.

the trunk version seems to have fixed that problem. *thanks Taco!!*

Re: [NTG-context] mplib
Hallo Taco et al
\startlua
local function finder(name, mode, ftype)
if mode==w then
return name
else
return kpse.find_file(name,ftype)
end
end
Jein!
Try this, a little more elaborate, version of finder:
local function finder(name, mode, ftype)
local found
if mode==w then
found = name
else
found = kpse.find_file(name,ftype)
end
print(MPlib finder: .. name .. - .. found)
return found
end
maybe that will give a clue.

in context you can use

this will generate the format if needed and reuse it

this first step runs with res=0, but there is no 'plain.mem' dumped.
For the other readers: res itself can't really be zero. It is either
a table, or nil. The actual return value is the status field in the
table, and that can vary from 0 (good run) to 3 (extremely bad run),
and you can end up with nil if you have invalid arguments.
(I have temporary appended 'dump;' to plain.mp)
After the above, you should have plain.mem in the local directory.
You can try printing res.term or res.log or even
print(table.serialize(res))
to check if what mp is doing.
after that I produced 'plain.mem' executing
'texmfstart texexec --make plain'
I assume that will create a tex plain.fmt file. But even if it
does create a .mem file, you will not succeed unless you are using
newmpost from the mplib-alpha-0.40 distribution and the values
you sset up for hash_size, main_memory, and param_size in the loading
stage are identical to the values used by newmpost from texmf.cnf
during mem generation.

this second step returns res=3.
Is there a find_file function necessary to find the mem-file given in

I thought 'plain.mem' is the default. But I see, there exists only
'metafun.mem'.
If you want to do the low-level thing, you have to read the
luatex manual carefully. MPlib is just like standalone metapost
in that it wants to load a mem file in non-ini mode, and that
file has to be generated before being used. Here is what you
wanted to do, using just the library core (I did cheat just a
little bit though, I added dump; at the end of my plain.mp):
% start low-level
\startlua
local function finder(name, mode, ftype)
if mode==w then
return name
else
return kpse.find_file(name,ftype)
end
end
mp = mplib.new ( {
hash_size = 10,
main_memory = 200,
param_size = 10,
find_file = finder,
ini_version = true
} )
if mp then
res = mp:execute('plain')
mp:finish()
end
mp = mplib.new ( {
hash_size = 10,
main_memory = 200,
param_size = 10,
find_file = finder,
} )
if mp then
res = mp:execute(\\beginfig(1) draw (0,0) .. (1,1) .. (2,1);
endfig; bye; )
tex.print([ .. tostring(res.status) .. ])
mp:finish()
end
\stoplua
% stop low-level
If you just want to run plain metapost images inside of
a context document (instead of metafun), it is much easier
to use Hans' high-level API (once again, you need dump;
at the end of plain.mp):
\startlua
metapost.process(
metapost.format(plain),
beginfig(0); draw (0,0) .. (1,1) .. (2,1); endfig;)
\stoplua
This makes sure that all memory values are the same,
that the mem file is cached inbetween runs, removes the
need for \\ and bye; etc.
Best wishes,
Taco

Some questions (and hidden wishes)
Does this mean that text between metapost graphic and context can be
really transparent? Currently \sometxt does not work with all macros,
(like an old feature request by Mojca to have two optional arguments for
setting the font in the gnuplot module). Will mplib mean that the
metapost

Now that you mention it: I still need to adapt the gnuplot module to
mkiv, but I'm a bit afraid of asking for help. (The most important
thing would be to get rid of that stupid catcode trickery inside
\startGNUPLOTscript ... \stopGNUPLOTscript that always tends to fail
when one needs it, and to have one-to-one conversion, so that %,#, $,
will have no special meaning.) Then, it would probably be a nice
benchmark to discover bugs in the library :)
For example, demos from this page (I'm not saying that they're too
useful since 100x100 is too low resolution anyway):
http://gnuplot.sourceforge.net/demo_4.3/pm3d.html
currently all fail because of the out-of-memory problem (10.000
times fill unitsquare scaled ... shifted ... withcolor ...), but
this might be a ConTeXt problem as well (the text inside
\startMPgraphic ... \stopMPgraphic probably needs to be stored
somewhere in TeX, even if there's no need for that).
let's discuss this a few months from now when i have more code in place
btw, how difficult would it be to add a lua api to gnuplot, in which
case we could communicate via lua tables
Peter Hedwig has already done some work on it:
http://peter.affenbande.org/gnuplot/
What his patch does: one calls gnuplot normally, and then, when you say
set term lua dashed fontsize 15
dashed fontsize 15 is parsed by lua. Then, gnuplot does its work,
and calls functions:
set_linestyle(3)
set_color(...)
draw_line(...)
What Peter did was a mapping from C to lua, so the actual code that
does draw_line is actually implemented in lua and can easily be
changed and/or adapted without recompiling gnuplot.
He now converts those function calls into TikZ Code, but that could
easily be adapted into anything.
So: output has already been implemented (and would only need to be
adapted), while input might need some tweaking. I'm sometimes using a
rather simple C++ library which opens gnuplot and pipes set terminal
..., plot ... commands to gnuplot, so one can pass a C table to
gnuplot. I could take a look at how it's done there. How do you
imagine passing lua tables to gnuplot?
Mojca
PS: no need to say that even though his terminal is much more popular
(it's the only decent LaTeX terminal I know) than the one for ConTeXt,
I have seen zero discussion on the gnuplot mailing list about any
intentions to integrate that code into gnuplot core.

Does this mean that text between metapost graphic and context can be
really transparent? Currently \sometxt does not work with all macros,
(like an old feature request by Mojca to have two optional arguments for
setting the font in the gnuplot module). Will mplib mean that the metapost
code can place any tex box at the desired location?
One thing which is really shaky in the current implementation is page
anchors. That is, marking something in a paragraph and then using the page
background to draw lines between different elements. Will such things be
easier to do and work correctly with display math? (I want to use these
effects in presentations, but have never managed to get a satisfactory
solution that works in display math).
I am assuming that there will be hooks so that packages like tikz to move
to a mplib backend.
Thanks,
Aditya

Its entirely possible that I'm missing something, but I was merely inquiring about running the same timing tests that you did with mplib, but instead using the existing MKII and MKIV image inclusion code.

How much of a speedup over the existing code does the mplib integration buy us for this benchmark? well, processing 15K mp graphics either runtime or delayed would take way much time (no fun timing) IIRC, beginning of the week we had a speedup of 50% against oldfashioned mkiv (mptopdf-in-lua) with a batched Metapost run, which is alread some 25% faster than batched Metapost in mkii mode (mptopdf-in-tex). And that was before we started optimizing, we are at least twice as fast now as we were then. And in the old system, batched metapost was a whole lot faster than runtime Metapost. Take a look at it this way: if you have a document stuffed full of backgrounds and borders and decorations, you may have a dozen unique decorations per page. On a 200-page book, the total runtime used by the new MPlib-based graphics system is then still less than a second (well, if you were using Hans' machine).

Re: [NTG-context] mplib
Hi, In addition to previous mails about the mplib project we now have funding for the programming part of the mplib project (budgetted 12KEURO) - dante : 6K - tug : 1.5K - tug india : 1K - ntg : 2K - cstug : 1K - gust: will fund a sub-project (metatype1 completion) TUG indicated that next year there could be additional funding but it looks like .5K is enough then, which means that the project funcing is secured. This project is especially nice because it permits us to have a tight luatex/mp pair. LuaTeX (opened up, configurable, tunable pdftex), TeXGyre (8 open type fonts, finaly with math etc), and MPLib (integrated graphical engine) help us boost tex into the future and without funding the programming and font conversion effort, i fear it would have taken many more years. It also means that some of you will have to do some pretty hefty testing of both machineries at the end of the year since context mkiv will be used as testbed. It may be clear that projects like this put quite a financial burden on user groups (there is already substantial continuous funding of texgyre by the mentioned user groups) and luatex is also sponsored (by oriental tex project as well as tug). Projects like this put a dent in the financial reserves of lugs. So ... if you're not yet a member of a local user group or tug ... consider joining since it's the user groups that keep the good work done ... Soon there will also be the option to support specific projects (tug project page).

Soon there will also be the option to support specific projects (tug project page). It is possible to contribute specifically to TUG's development fund, which is TUG's pigeonhole for dev projects, at https://www.tug.org/donate.html. Any donations to that now will end up going to luatex/mplib. Donations are, of course, greatly appreciated :). As Hans said, new members for TUG (http://tug.org/join.html) or any other user group (http://tug.org/usergroups.html) are also greatly appreciated.
