mathml linebreak?

Hi, usually it is possible to break long formulas. But is there a way to do so, when formula is coded in mathml (see example below)?

Missing keys in reference line (letter module)
by Florian Wobbe 08 Jun '13

Hi, the keys "name" and "phone" are not included in the reference line using the minimal example from the correspondence manual below. The reference line just contains the date. Also changing the alternative from "a" to "b" has no effect. What am I missing? I upgraded to the latest beta and the header of s-cor-01.mkvi states version 2013.01.14.

\at and \in woes with \startcomponent….\stopcomponent
by Alan Bowen 07 Jun '13

07 Jun '13

In my component files, the tools for cross-references work except for \at and \in. These commands produce links that display properly but go to a null page, i.e., nowhere. Sample file: Test.tex \setupinteraction[state=start,color=blue,% contrastcolor=darkred, style=rm, click=yes, display=new, ] \startcomponent Test.tex %\starttext reference on \at[myref1] reference in note\in[myref1] reference: \at[myref1]n\in[myref1] \page text\footnote[myref1]{a footnote} more text\footnote[myref2]{another footnote} \stopcomponent %\stoptext If I run the file with \starttext…\stoptext, all is well.

Re: [NTG-context] How to hack the lua files
by Lance Larsen 07 Jun '13

07 Jun '13

If I modify a core lua file how do I remake the format file? Is this something that is done from mtxrun.exe? I would certainly prefer to use a hook rather than modifying a core file, but how do I identify the hooks that are available? Is there a list of hooks that are available, or a standard way that hooks are called from the context code so that I can look for an appropriate hook? Where do I place my hook scripts? Is there a guide that is available that might get me started? What I trying to do is map equation references to the equation number generated by context. So for example, if I have an equation: \placeformula \startformula \NC F = m a \NC \NR[eq:newtonslaw] \stopformula I need a way to log the fact that 'eq:newton' became something like equation (2.3). I hoped there was a tracker that printed this out (maybe there is, but I haven't found it). So I thought maybe I could find where equation numbers are defined by context and add a tracker. The code in 'strc-ref.mkvi' and 'strc-ref.lua' looked promising. Incidentally, is this where equation numbers are created, or should I be looking in another file? Is there a lua function that gets called consistently around the time equation numbers are defined where the equation reference (i.e. eq:newtonslaw) and the associated equation number are both available and could be logged? I tried adding a new tracker in strc-ref.lua to see if I could narrow down where the labels are created, but my tracker did not seem to work. Therefore, I identified a tracker that was working and tried to modify the output slightly only to find that this did not work either. It is not clear to me at present how context loads the lua files. I hoped that it loaded these directly, so that changes would take effect immediately. -Lance Larsen ------------------------------ On 6/7/2013 1:20 AM, Lance Larsen wrote: > I have a version of context standalone installed, and I am trying to > add some functionality I need to strc-ref.lua.

It's not a problem to add functionality (lots of hooks for that) but best do that in a local module that gets loaded at runtime then.
