i prototyped it but the chairman of the CMS has to check it before we decide to enable it one complication is that $ \autofences x | \frac{a}{x}$ $ \autofences ( \frac{a}{x} + b | x )$ should also work (lone middles)

Hi,

I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change):

\setupbodyfont[pagella]

\starttext

\setupmathdelimited    [topoffset=.2\exheight]

\definemathdelimited    [fourier]    [rule=no,     left=\zerocount,     right="FE944]

\definemathdelimited    [courier]    [rule=no,     left=\zerocount,     right="FE946]

\definemathdelimited    [xourier]    [rule=no,     left=\zerocount,     right="FE948]

$ \fourier{(z+1)} $

$ \fourier{(z+1)} + \sqrt[2]{1}$

$ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $

$ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $

$ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $

$ \widehat{x^2 + 2x + 2} $

\stoptext

This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so

\def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck

will work. For thise in finance we now have

$ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $

these are basically radicals (like sqrt) with two sided symbols.

Hi Hans, Thanks a lot for the example. It works great in most cases, however what I stumbled upon is with the interval notation, in particular the following cases arise: - closed interval: easy, since the delimiters are [... ; ... ] - open interval: not easy, since the delimiters are ]... ; ... [ (or with a parenthesis as in the US, but there it works) - semi open interval: not easy, since the delimiters are either [... ; ... [ or ]... ; ...] (or in the US [...; ...) or (... ; ...]) I guess there is a need for a special definition for these. Maybe they're already in the works... By the way, if I define in the preamble \autofences, is there a command to disable it locally? Would be very helpful to deal with the above situations.

Hi Hans,

Will |\mvert|and|\midalso be included in the \autofencelogic? It would be quite useful.| we don't have \mvert so i'll add that ... in a next upload you can do
