Hi,
I am attaching myway on using matharrow. Are there any suggestions before I release it to public?
I found some surprises while making this my way.
Now that you're all experts in arrows: I'm still looking for \overrightharpoonup that would: - be small enough, so that it would still look ok when placed over (dotless) i or j. - decrease with style: $\overrrightharpoonup{AB}_{\overrightharponup{CD}}$ the second arrow should be smaller.
1. Somewhere along the line of development, \xrightarrow{text} changed to placing text at the bottom of the arrow (rather than the top as in amstex). This is not a bug, just something that works differently. Should this be changed? These arrow definitions are pretty new, so I do not think that a change at this stage will effect too many users. It may not be possible to change later for compatibility reasons.
I guess that you might even be the only one who used that so far, so if you want compatibility, fix it now! (I never used that functionality in LaTeX, so I don't know how it works there).
2. Something goes wrong with palatino (used by mag-01). Have a look at the \xmapsto and \xrightleftharpoons and \xleftrightharpoons in the pdf. \xmapsto can be corrected by changing its defintion to
\definematharrow [xmapsto] [3599] [\mapstofill]
Basically, providing a bit more cusion on the left, so that the middle \relbar not overlap the \mapstochar.
Should this definition go to math-ext.tex or to something specific to palatino. I have not tested with other fonts, but what is the general strategy when definitions differ for different fonts?
Taco - now that you have enough experince with cows: do you have any suggestions about how to create nice arrows with antykwa-torunska as well? Mojca
