Hi, It seems there is a bug with the command \blank in the latest standalone context. If you compile with ConTeXt (texlive 2015), the result is as expected.

The `\somewhere`-macro
by Norbert Melzer 28 Aug '15

28 Aug '15

The wiki states on page http://wiki.contextgarden.net/Latex_Packages#varioref that the macro `\somewhere` can be used to get same behaviour as varioref gives in LaTeX: > varioref > Context provides similar functionality using \somewhere Some more searching around made me find http://wiki.contextgarden.net/Command/somewhere There I can see, that I have to provide 2 text-arguments in curly braces and the references name in squarebrackets. So I did exactly that in an experiment. \somewhere{Foo}{Bar}[foo:bar] This does create a clickable “Foo” when the reference exists somewhere in the document, independent off the fact that this reference is on the same page or anywhere else. When the reference does not exists, “foo:bar” is typeset. I am using: ```plain $ context --version mtx-context | ConTeXt Process Management 0.61 mtx-context | mtx-context | main context file: /usr/local/texlive/2015/texmf-dist/tex/context/base/context.mkiv mtx-context | current version: 2015.05.18 12:26 ``` Example: ```tex \setupinteraction[state=start] \starttext \startsection[title={Foo-Bar},reference={foo:bar}] Blubberblubb, \somewhere{Foo}{Bar}[foo:bar]. \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \somewhere{Foo}{Bar}[foo:bar]. \stopsection \startsection[title={Bar},reference={bar:foo}] \somewhere{Foo}{Bar}[foo:bar]. \stopsection \stoptext ```

XML expression to read HTML classes
by massifr＠fastwebnet.it 27 Aug '15

27 Aug '15

Hello list, I'm working on HTML typesetting with ConTeXt. I wrote a custom expression to test whether an element has a class: function xml.functions.classes(classAttr) local classes = {} if classAttr then for c in string.gmatch(classAttr, "%S+") do if (string.len(c) > 0) then classes[c] = true end end end return classes end function xml.expressions.hasClass(classAttr, className) if classAttr and className then return xml.functions.classes(classAttr)[className] ~= nil end return false end This way I can write this in my xmlsetup: \xmlsetsetup{#1}{p[hasClass(@class,'myclass1')]}{html:p:myclass1} That is better than - p[@class='myclass1'] (it fails when you have more classes) - p[contains(@class, 'myclass1')] (it gives you false positives when you have class="myclass12") That works, but I would like to write: \xmlsetsetup{#1}{p[hasClass('myclass1')]}{html:p:myclass1} omitting the @class argument, because it's obvious. To omit it I need to access the current collected element. At page 25 of "Dealing with XML in ConTeXt MkIV" it is said that the predefined variables "list","l","ll" (I think I need that one) and "order" are available, but I did not manage to access them. How can I get the current element in Lua to write local classAttr = xml.attribute(currentElement, "", "class") ? Thanks in advance, Massi
