\xrightleftharpoons macro for <math>-environment
Closed, ResolvedPublic


Author: matthias

"Very often chemists need a longer version of reaction arrows (\rightleftharpoons) with the possibility to put text above and below. Analogous to ams-math’s \xrightarrow and \xleftarrow this package provides the macro \xrightleftharpoons."

It would be nice if someone installs the package "chemarr".

Seems a very old request (from 2009). Please reopen if still needed.

Errr, on the contrary, it is terrible that this is still not resolved, not a reason to close it. *shaking head*

Matthias Mailänder 70 open bugs can not be resolved at the same time. They have to be ordered and someone needs to take care to resolve them.
It does not help if the bug is open and nobody plans to work on a solution.
In order to find someone to work on a solution for the problem the following questions should be answered:
Is there an example how to create the desired output with MathJax?
How is the rendering result expeced to look like?
Which is the expected MathML representation?
On which pages should this command be used and how would this improve the layout?

Physikerwelt raised the priority of this task from Low to Medium.
Physikerwelt set Security to None.

I guess the desired feature is included in the mhchem package T98306?
