I agree with this! A feature could be to save the last used random value in the tuc, so that one can continue with the former used sequenz. But this should not be used automatically, too. May be one should than say \setupsystem[random=last] Wolfgang

This does not work! I get allways the same. And shouldn't the tuc-seed be overwriten from my os.time-seed? Wolfgang

randomize
by Wolfgang Werners-Lucchini 07 Apr '10

07 Apr '10

Hallo, I get allways (10 times at least) the same result: ------------------------------------------------------------- \starttext \startluacode math.randomseed(os.time()) \stopluacode Encode your Name and Surname as a \startluacode local a = {'null-terminated', 'dollar-terminated', 'Pascal'} context('%s string', a[math.random(1,3)]) \stopluacode \stoptext ------------------------------------------------------------- How can I randomize this?

Extra page created at end of document
by Tom 06 Apr '10

06 Apr '10

The following code creates an extra page at the end of the pdf for a total of 3 pages: \setuppagenumbering[location=,alternative=doublesided] \setuppagenumber[state=stop] \starttext %\startfrontmatter \input knuth %\stopfrontmatter \stoptext But this code doesn't create that third page: \setuppagenumbering[location=,alternative=doublesided] \setuppagenumber[state=stop] \starttext \input knuth \stoptext I need to handle the creation of my book using frontmatter, etc. parts and don't want to create that unneeded page at the end.

Metafun in MacTeX 209 distribution
by jindrich Ruzicka 06 Apr '10

06 Apr '10

Hello people, I installed Mac TeX -2009 Distribution on a new iMAC. when I try to run texexec on a Context file that includes a metapost program, I receive no picture that is defined in metapost part. (btw in my linux installation it works) What I can find in log file is: ... runsystem(texmfstart texexec --batch --output=dvips --mpformat=metafun --mptex --nomp --once obrazek-mpgraph)...disabled. ... Running this sequence manually and reruning the 1st texexec I receive what I expect. Is it a feature of Mac distribution or there is a mismatch in some file/directory permissions? (mptopfd, ...) Are there another installation steps needed after fresh MacTeX installation? the test file is: \startuseMPgraphic{def} ... \stopuseMPgraphic \startuseMPgraphic{obr30} \includeMPgraphic{def} ... \stopuseMPgraphic \starttext test \placefigure[here][fig1]{yyy} {\useMPgraphic{obr30}} end of test \stoptext Nice day, Jindro

mkiv: wide gap between name and text of enumerations
by Matthias Weber 06 Apr '10

06 Apr '10

Dear all, I use in mkii \defineenumeration [blurb] [text=Blurb, way=bysection, location=hanging] \starttext \startblurb Here should only be a small gap. \stopblurb \stoptext to get something like Blurb 1 Here should only be a small gap. However, the same input gives in mkiv Blurb 1 Here should only be a small gap. Is there a way to narrow the gap? Thanks, Matthias
