Hi ConTeXt mailing list,
I am using the extensible arrows and I am not really satisfied with the
looks of it.
The most important issue I have is that the vertical spacing is too much.
You can see this in the attached picture: the left arrow is using
\xrightarrow{\neq a} and the right arrow is using \stackrel{\neq
a}{\longrightarrow}. I think the right one (with stackrel) looks more
natural. Is there a way to setup the vertical spacing?
Another thing I noticed is that the line is not very consistent. This might
be a font issue (I am using Euler). Luckily, the inconsistent overlap is
barely visible when printed.
Thanks again!
Groetjes,
Joshua

MPinitializations are shared by all instances (normally), that is if initializations=yes is set in \defineMPinstance.

Using \definemathstackers I can set the voffset to adjust the vertical spacing. This is exactly what I needed, thanks! However, I couldn't use the ahlength variable. I tried different values, but it doesn't seem to change anything (and the current arrowhead is tiny). (Using startMPcode and drawarrow gives a big arrowhead.) Also I noticed that the content of \rightarrow{...} was not in mathmode, so I tried using middlecommand=\mathermatics (I found this on the wiki and in the docs). But that doesn't change anything. Is this a bug? Example: \useMPlibrary[mat] \definemathstackers [mp] [alternative=mp, voffset=-.3\mathexheight, middlecommand=\mathematics] \definemathextensible [mp] [rightarrow] ["2192] \startMPinitializations ahlength := EmWidth ; % Does not work? ahangle := 30 ; ahvariant := 1 ; ahdimple := 4/5 ; \stopMPinitializations \setuppapersize[A7] \starttext $A \rightarrow{$\neq f$ and $\neq g$} B$ $A \rightarrow{\neq f \text{ and } \neq g} B$ % Is not typeset in mathmode \stoptext Thanks in advance, Kind regards, Joshua -----Original Message----- From: Alan Braslau <braslau.list@comcast.net> Sent: 07 August 2018 17:01 To: Joshua Moerman <context@joshuamoerman.nl> Cc: mailing list for ConTeXt users <ntg-context@ntg.nl> Subject: Re: [NTG-context] xrightarrow is not straight On Tue, 7 Aug 2018 10:42:01 +0200 "Joshua Moerman" <context@joshuamoerman.nl> wrote: > Hi ConTeXt mailing list, > > I am using the extensible arrows and I am not really satisfied with > the looks of it. > > The most important issue I have is that the vertical spacing is too > much.
