Hello, It's a repost, because version 2008.04.10 still fails: What about the integration of this patch from Wolfgang Schuster into the distribution: - Forwarded message from Wolfgang Schuster <schuster.wolfgang(a)googlemail.com> - Date: Fri, 22 Feb 2008 11:57:37 +0100 From: Wolfgang Schuster <schuster.wolfgang(a)googlemail.com> Reply-To: mailing list for ConTeXt users <ntg-context(a)ntg.nl> To: mailing list for ConTeXt users <ntg-context(a)ntg.nl> Subject: Re: [NTG-context] \chemical and MKIV On Thu, Feb 21, 2008 at 11:23 PM, Peter Münster <pmlists(a)free.fr> wrote: > Hello, > > The following test-file produces an error: > > % engine=luatex > \usemodule[chemic] > \starttext > \chemical{CO_2} > \stoptext This is tooo long. \usemodule[chemic] is enough to produce the error with mkiv.

Hallo, I have a few silly questions about tex.print() To produce $\sqrt{2}=1.4142135623731$ it should be enough to write tex.print("$\\sqrt{2}=" .. math.sqrt(2) .. "$") or better tex.print([[$\sqrt{2}=]] .. math.sqrt(2) .. "$") but that's both not working. The following instead does the job: tex.print("$\string\\sqrt{2}=" .. math.sqrt(2) .. "$") why? Another question: What is the differenz between 'tex.sprint()' and 'tex.write()'? Wolfgang

Hallo, the following compiles ok, but gives me an status 3=fatal error. Can someone please point me to the error? \startlua mp = mplib.new ( { hash_size = 100000, main_memory = 2000000, param_size = 100000, } ) 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 Wolfgang

new version luatex / mkiv
by Hans Hagen 12 Apr '08

12 Apr '08

Hi, There is a new version of luatex and mkiv. You need to update them together. The best place to get them is the contextgarden (which will probably have the new versions pretty soon). This release of is rather substantial: no longer is metaposts called, but mplib is used instead. This bring down metapost runtime and conversion to nearly zero. The user interface is the same, but the implementation is different. Tomorrow (or so) taco will make releasenotes.

new version
by Hans Hagen 11 Apr '08

Hi, concerning the mplibrary in mkiv ... - it does not use the metafun mem file; when formats are generated a special mem file is made and put alongside the context format - however, this only happens when a new version is found (is the case with a new zip), or when an error is encountered in the format (compatibility issue) - in case of doubt, or when you patch metafun, you can say ctxtool --touch texexec --make i will try to make this more robust in the future the new mkiv mp graphics implementations is prepared for mixed usage, i.e. we can use multiple metapost formats; i'm still not sure about the interface, for instance: \startuseMPgraphic{metafun:bla} ... \startuseMPgraphic{mpost:bla} ... or so, more news later Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

mpost updating
by Wolfgang Werners-Lucchini 10 Apr '08

10 Apr '08

Hallo, I have updated an older ConTeXt (ver: 2007.07.29 22:06 MKII) with a aktuell mpost. I have used 'http://minimals.contextgarden.net/current/bin/metapost/mswin/bin/' as source. The command 'texmfstart texexec --autopdf --make --all' produces no metapost formats at all. Calling 'mpost.exe' I get a messagebox with the error: 'procedure entry point "kpse_record_input" in DLL "kpathsea356.dll" not found' (my translation from german). What is wrong here? Wolfgang
