Hi,
Some questions/remarks about math fences
1. When using
\definemathfence[colorbracket][bar][middle=0x7C,color=red,
command=yes]
\starttext
\startformula
\colorbracket{\frac {a}{b}\fence a = b}^n
\stopformula
\stoptext
The delimiter is of the wrong color (black instead of red), and the clause
after \fence is red. I am doing something wrong or is it a bug.
2. For some types of expressions, for example, probability, the middle
delimiter should have the space similar to mathrel, rather than mathord.
For example, while typing I often use:
\Pr\left( X = \frac {a}{b} \,\middle|\, Y = \frac{c}{d} \right)
Would it be worthwhile to add these extra spaces by default (not sure what
is the convention in physics/quantum mechanics for bra and ket notation)
or as an option.
3. Finally, why are the default values of left, middle, and right = 0x2E.
Isn't 0x7C a better default?
Thanks,
Aditya

I'll add \mskip\thinmuskip around the middle ... no clue what key/value to use so we can wait tile someone compliants > 3. Finally, why are the default values of left, middle, and right = > 0x2E.

Well, the period is (for tex) special in the sense that it is a nop so if you only want ( and no ) then explaining to a user that a period is to be used to nil the right symbol is somewhat less troublesome. One sets up the wanted symbols anyway.

Of course. I use unmatched delimiters so infrequently that I forgot about it. Math fences replace most of the functionality of my old mathsets module. The only missing feature is the text key, but that is a specialized use case, so I'll just update mathsets so that it uses math fences in the background. I it really necessary to use Unicode characters to specify left, right, etc? I ink that most math users will be more comfortable using literal symbols, {,[,(,|, etc or tex names \Vert, \vert, etc. Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

In that case, no extra test it needed. > keep in mind that one can clone > > \definemathfence [fancybracket] [bracket] [command=yes,color=red] > > so if there is a properly named base set (i tend to clean expressive verbose > names, at least as base commands instead of all the weird ones that showed up > over time (along with entities with slightly different names) ... clean math > as start and we can always add dirty math as instances Agreed. Unmatched brackets are not so common, so this the default set is a reasonable starting point.
