question about an lpath
by Pablo Rodriguez 31 May '16

31 May '16

Dear list, I have the following sample: \startbuffer[demo] <div class="super"> <h1>Chapter</h1> <p>This is the only paragraph in red.</p> <p>This is another paragraph.</p> <p>This is another paragraph.</p> <p>This is another paragraph.</p> <p>This is another paragraph.</p> </div> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{*}{xml:*} \xmlsetsetup{#1} {div[contains(@class,'super')]/p[position()==1]} {xml:p:super} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:div \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:h1 \title{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:p:super \bgroup\red\xmlflush{#1}\egroup\par \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext Would it be possible to have another lpath for xml:p:super similar to the following CSS selector? (Sorry, this is much easier for me.) div.super > h1 + p {} After searching in xml-mkiv.pdf, I’m afraid I haven’t been able to find which might be the lpath replacement for "+". Many thanks for your help, Pablo -- http://www.ousia.tk

LuaTeX finds font, mtxrun --fonts does not list it?
by Sandra Snan 31 May '16

31 May '16

I'm trying to add a ttf font (Futura) so I can use it in ConTeXt. I've ran mtxrun --script fonts --list --all |less looked at a ttf font that was there, copied my Futura ttfs to the same directory it was in, and ran mtxrun --script fonts --reload --force But I still can't find it in mtxrun --script fonts --list --all |less nor can I use it in ConTeXt. (The filenames don't have spaces.) The curious thing is that the luatex cache has it. It's listed in /home/sandra/.texmf-var/luatex-cache/generic/names/luaotfload-names.luc under various names, all starting with "futuralt". Curiously, /home/sandra/.texmf-var/luatex-cache/context/[number]/fonts/otf/futuralt-book.tm[ac] exist. But the only "book-" related name in luaotfload-names.luc is futuraltbook, not futuralt-book. Neither worked in ConTeXt, though. How do I move forward with this, how do I add ttfs so that ConTeXt understand them? Sandra

Avoiding \startformulas starting new paragraph
by Hans Åberg 30 May '16

30 May '16

In the example below, \startformulas starts a new paragraph with indenting, whereas \startformula does not. Is there any way to avoid that? \setupbodyfont[xits,10pt] \setupindenting[yes, medium, next] \starttext Some text. Some more text \startformulas \startformula 2 + 2 = 4 \stopformula \startformula 2 + 2 = 1 \mod 3 \stopformula \stopformulas ending here. Some more text \startformula 2 + 2 = 1 \mod 3 \stopformula ending here. No more text. \stoptext

Set default background color or pattern for tables
by Nicola 30 May '16

30 May '16

I'd like to set a default background color for all the tables in my document. This is what I have tried (using the latest beta): \setuptables[background=color,backgroundcolor=red] \starttext \starttable[|cm|] \HL \NC \bf R \NC \AR \NC A \NC \AR \HL \NC \bot \NC \AR \NC 1 \NC \AR \stoptable \stoptext No red background, though. What am I missing? The next step would be how to use a hatched pattern, but for now I'd be happy with a flat color. Nicola

Incorrect math kerning
by Aditya Mahajan 30 May '16

30 May '16

Hi, This is based on a question about latex on tex.stackexchange: http://tex.stackexchange.com/q/312098/323 but context shows the same behaviour. The subscript "i" in the following example is kerned incorrectly (it is too far away from W). Is this a bug in the font, or with the fontloader? \setupbodyfont[cambria] \starttext \startTEXpage[offset=2mm] $W_i^i$ \stopTEXpage \stoptext Thanks, Aditya

How to start the demo in modules
by Mojca Miklavec 30 May '16

30 May '16

Hi, MKII uses \doifnotmode{demo}{\endinput} to enter the demo mode in modules. I see that MKIV now switched to \continueifinputfile{s-something.mkiv} The question arises: What should I suggest to a module writer for a relatively simple file that doesn't use any MKIV features and provides just the module file t-something.tex? Is it OK to keep using "\doifnotmode{demo}{\endinput}" also in MKIV? Thank you, Mojca

Fonts distributed with a ConTeXt document
by Freddy Omar López Quintero 30 May '16

30 May '16

Hello! Sorry if the answer is obvious but I have no found how solve this problem. I would like share a document written using ConTeXt that employes different fonts, but the recipients have no possibilities to install those fonts in their computers. It is possible use fonts that are in the same directory that the .tex document? My folder is something like: ./context.tex ./font1.ttf ./font2.ttf ... ./fontn.ttf Thanks in advance! -- «...my role is to be on the bottom of things.» Donald Knuth

Allow for hyphenation in 'firstline' ConTeXt feature ?
by josephcanedo＠gmail.com 29 May '16

29 May '16

Dear all, I use the nifty ‘firstline’ feature ConTeXt offers (using a larger font size, line mode, 1 line only) and I notice that the last word of the first line is never hyphenated even if doing so could reduce underful in the first line. From typo-fln.lua it looks like that’s expected as the decision to break the first line happens only at nodes which are not glyphs, disc_nodes or kern nodes. There is a comment saying it could be added some option to handle disc nodes. I’d be happy to add such option but do not have enough knowledge in nodes manipulation in luatex, especially those related to hyphenation. Would it be very difficult to add such option please ? I post a MWE showing some extreme non real non sensible case, to double check that hyphenation is never performed. \definefirstline[FirstLine][alternative=line, style=\tfd] % exegerate size \starttext % exagerated case as MWE \setfirstline[FirstLine] A few words larger largestwordwordlongwordthatcouldbehyphenated bar bar. A few words larger largest word word foo bar word bar bar. A few words larger largest word word foo bar word bar bar. A few words larger largest word word foo bar word bar bar. \stoptext Thanks a lot, Best regards Joseph Canedo

Tabulate \NN not working
by Hans Åberg 29 May '16

29 May '16

For some reason, the use of \NN as in the first table below is not working. It works fine using math columns, though, as in the second table below. \setupbodyfont[xits,10pt] \starttabulate[|c|c|] \NN x \NN ¬x \NR \HL \NN 𝕗 \NN 𝕥 \NR \NC 𝕥 \NN 𝕗 \NR \stoptabulate \starttabulate[|mc|mc|] \NC x \NC ¬x \NR \HL \NC 𝕗 \NC 𝕥 \NR \NC 𝕥 \NC 𝕗 \NR \stoptabulate
