Conditionals
by Troy Henderson 29 Sep '12

29 Sep '12

I have a list of numbers, 2, 6, 7, 8, 12, 14, 18, 20, 186, 188, 316, 318, 354, 372, 376 that I would like to use as exceptions in a \dostepwiserecurse loop. That is, within the loop if \recurselevel is NOT EQUAL to either of these numbers, then I want to do something -- otherwise, I simply increment \recurselevel. I would appreciate an example of how to do this. Thanks, Troy Henderson

External Figure inside MPpage
by Troy Henderson 29 Sep '12

29 Sep '12

I was wondering if there is a way to place an external figure (JPG/PDF) inside a MPpage. The following does not work. \startMPpage \externalfigure[spiral/andrew/andrew.jpg][height=4.75in] \stopMPpage Troy Henderson

Bib module -> master thesis title not displayed in placepublications
by Xan 28 Sep '12

28 Sep '12

Hi, I have this: @mastersthesis{meva-memoria, author = "Bordoy, Xavier", title = "Algunes contribucions a l'estudi del problema de la paraula per a grups", school = "Departament de Ciències Matemàtiques i Informàtica. Universitat de les Illes Balears", year = "2009", address = "Palma de Mallorca", note = "Available in \from[bib:memoria-master] (in catalan)" } and when I put \placepublications[criterium=text] I only recive: "X. Bordoy, Master's thesis, Departament.... Univeritat... Palma de Mallorca (2009). Avaliable in .... (catalan)." but not title? Why? Can I display title in that? Thanks in advance, Xan.

\define a command with square-bracket arguments
by Sietse Brouwer 28 Sep '12

28 Sep '12

Hi all, As I understand it, \define[2] is preferred over \def#1#2 because it refuses to overwrite existing commands. \define[2]\mycommand{code code code} defines a command to be invoked with \mycommand{...}{...} Can I use \define, or a related command, to define a command that takes square-bracket arguments, like so: \mycommand[...][...] ? When I type \define[1][2]\mycommand{code code code} that doesn't work. Cheers, Sietse

Referring to multiple elements
by Marco Patzer 28 Sep '12

28 Sep '12

Hi, how can I refer to multiple elements at the same time? \starttext \startplacefigure [title=foo, reference=alpha] \stopplacefigure \startplacefigure [title=bar, reference=beta] \stopplacefigure \startplacefigure [title=bar, reference=gamma] \stopplacefigure \in{figure}[alpha,beta,gamma] \stoptext This outputs “figure 1”. What I'd like to have is “figure 1-3”. Marco

verbatim text: \type, \tex and co.
by Alan Braslau 28 Sep '12

28 Sep '12

Hello, Can someone indicate how to typeset $L_{α+β}$ as verbatim text? (\arg{} doesn't help here...) Furthermore, I suppose that typesetting Greek characters verbatim depends also upon which \tt font is being used. Alan

[tabulate] colored background
by Philipp Gesang 28 Sep '12

28 Sep '12

Hi all, the background mechanism of tabulations is quite simplistic: it extends only to the first line of a cell irrespective of its length. Example: ······································································· \starttext \starttabulate[|p|r|] \CM [red] \input knuth \NC was said by The Don \NC \AR \stoptabulate \stoptext ······································································· Is there a way to get the whole cell covered? (Textbackgrounds only color the area where text is, not the entire cell.) Regards Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

Parsing [key=value, key2=value2, ...] with Lua
by Sietse Brouwer 27 Sep '12

27 Sep '12

Hi all, I've found a helper function that does this: utilities.parsers.settings_to_hash('ape=1, note=2, mice=3') --> { ["ape"] = 1, ["note"] = 2, ["mice"] = 3 } This makes me very happy. This function and its friends are stored under utilities.parsers, and defined in util-prs.lua; I've listed them below. Perhaps they'll be useful to somebody else, too. I should probably add this info to http://wiki.contextgarden.net/Commands_with_KeyVal_arguments, but dinner first. Cheers, Sietse First some examples of what the most important functions: utilities.parsers.settings_to_hash('ape=1, note=2, mice=3') --> { ["ape"] = 1, ["note"] = 2, ["mice"] = 3 } -- settings_to_hash takes an option 'strict', -- I assume that has to do with space-trimming. utilities.parsers.settings_to_array('ape, note=2, mice, ape') --> { "ape", "note=2", "mice", "ape" } utilities.parsers.settings_to_array('ape, note=2, mice, ape') --> { ["ape"]=true, ["note=2"]=true, ["mice"]=true,} Complete list of functions (and one table) in utilities.parsers: T.add_settings_to_array T.arguments_to_table T.array_to_string T.getparameters T.hash_to_string T.listitem T.make_settings_to_hash_pattern T.patterns : table: 0x9a67680 T.patterns.settings_to_array : userdata: 0x9a6c904 T.patterns.settings_to_hash_a : userdata: 0x9a6a694 T.patterns.settings_to_hash_b : userdata: 0x9a6ad6c T.patterns.settings_to_hash_c : userdata: 0x9a6b424 T.settings_to_array T.settings_to_hash T.settings_to_hash_strict T.settings_to_hash_tolerant T.settings_to_set T.simple_hash_to_string T.splitthousands

metapost dashpattern (on 1) not shown in Mountain Lion Preview
by Xiao-Yong Jin 26 Sep '12

26 Sep '12

Dear all, I just upgrade to Mountain Lion and found out that "dashed dashpattern (on 1)" no longer shows any line in Preview. The attached file is a snapshot of the Preview window showing the pdf file generated by the following code. \starttext \startMPpage draw unitsquare scaled 4cm dashed dashpattern (on 1cm off 1cm) ; draw unitsquare scaled 4cm shifted (5cm,0) dashed dashpattern (on 1cm) ; draw unitsquare scaled 4cm shifted (10cm,0) dashed dashpattern (off 1cm) ; setbounds currentpicture to boundingbox currentpicture enlarged 0.1cm ; \stopMPpage \stoptext You can see, from the attached file, that the unitsquare which was supposed to appear in the middle does not show up in the Preview window. However the same file is displayed correctly in Acrobat Reader. I am not sure whether it is a context problem, or it is just a bug in Mountain Lion. I found out this issue when I saw that all the pdf files I previously generated with gnuplot context term are showing up incorrectly under the Preview after upgrading to Mountain Lion. I had to change the dash pattern in file "metapost/context/third/gnuplot/mp-gnuplot.mp", so the pdf generated by gnuplot context term can be viewed correctly with Preview under Mountain Lion. Best, Xiaoyong

No entry in the list of figures? (now without .pdf)
by Procházka Lukáš Ing. - Pontex s. r. o. 25 Sep '12

25 Sep '12

Hello, suppose the following example: ---- \starttext \startappendices \placelistoffigures % OK \placefigure[place]{Caption}{\externalfigure[cow][width=.25\textwidth]} \chapter{Foto} % Try to comment this! \placelistoffigures % No entry \placefigure[place]{Caption}{\externalfigure[mill][width=.25\textwidth]} \stopappendices \stoptext ---- This would generate two LOFs - one in the begin of the document, another in the chapter "Foto". Both of them should have two entries - "cow" and "mill". The former is OK; but the latter has no entry. If you comment "\chapter{Foto}", both LOFs are OK. What's the problem? Best regards, Lukas NB: Maybe similar question will appear in the mailing list with the resulting .pdf - this mail waits for moderator's approval; thus this reduced version. -- Ing.
