\big\lfloor and \big\lceil do not work

\big\lfloor and \big\lceil do not work

[Aditya Mahajan]

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.

Aditya

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.

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.

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.?

No. They work with the latest beta.

Thanks for the bugfix.

Other missing delimiters:

\lmoustache, \rmoustache, \llbracket, \rrbracket, \llangle, \rrangle, 
\lgroup,  \ulcorner, \urcorner, \llcorner, \lrcorner.

Hopefully, I have not missed anything.

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
