Hi, This is based on another question on TeX.SX http://tex.stackexchange.com/q/242256/323 Minimal example: \starttext \startlines $\big\lfloor x \big\rfloor$ % No delimiters $\Big\lfloor x \Big\rfloor$ % No delimiters $\left\lfloor x \right\rfloor$ % Works \stoplines \stoptext Any idea what is happening? (This also fails with cambria, so something is wrong with the settings) On a related note, the following does not work either: \starttext $\left\langle x \right\rfloor$ \stoptext Not that one would ever use such a notation, but it is weird that it does not work.

As I said in the previous email, \langle ... \rfloot are not typically used together, so there is no need to add them as a fenced pair. I just happened to use them together because I was testing whether other delimiters are working or not.

(there is a special fences subsystem, also with some checking for mismatch and so, needed for unattended processing as in mathml)

I did not know that these were enabled by default. I'll try to document this behaviour because it can be quite surprising to someone coming from plain tex or latex. Aditya

one can pair anything fenced so also these (the main issue one doesn't pair but uses one only in which case tex has to be tricked)

OK. Any hints about the missing \lfloor, \lceil with \big etc.? Aditya

No. They work with the latest beta. Thanks for the bugfix. Aditya

Other missing delimiters: \lmoustache, \rmoustache, \llbracket, \rrbracket, \llangle, \rrangle, \lgroup, \ulcorner, \urcorner, \llcorner, \lrcorner. Hopefully, I have not missed anything. Aditya

Hi Hans, While you are at the delimiters, could you please add also \| as an alias for \Vert? The command \| exists in plain TeX (and in many other TeX packages used by mathematicians) as an alias for the double bar norm, \Vert, or ||, while as of now in ConTeXt it is an alias for the single bar |. Best regards: OK

\| is already for a long time a single bar (and also in text mode), just like \> etc are singles so consistency is more important here than compatibility with plain btw, i've added\lfence and \rfence (in next beta) as shown below: \starttext \def\foo{\frac{\frac{1}{\frac{1}{x}}}{\frac{1}{\frac{1}{x}}}} \setupmathfence[brace][color=darkyellow] \setupmathfence[bar][color=darkred] \setupmathfence[doublebar][color=darkred] $\left\| \foo \right\|$ $\left| \foo \right|$ $\left{ \foo \right}$ $\lfence{||} \foo \rfence{||}$ $\fenced[doublebar]{\foo}$ \definemathfence [db] [bracket] [command=yes,color=darkblue] $\fenced[db]{\foo}$ \definemathfence [db] [doublebar] [command=yes,color=darkgreen] $\fenced[db]{\foo}$ \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
