Hi!
I'm in the process of converting some projects to LMTX. Combinations lacking “”before” and “after” keys (that place content before/after the *entire* combination, rather than the individual cell pairs), I came up with the following ugliness – which worked for longer than it deserved:
[...]
I added vertical spacing and mid-aligned the content without having to change the sources, that was the idea. However, this fails in LMTX:
Undefined control sequence \pack_combinations_start
Does LMTX offer finer control over the combinations or do I have to rewrite the sources files (to either use floats or surround the combinations with the required commands)?
1. Your changes don't work anymore because LMTX handles optional arguments in a different way than MkIV. As a result of this change a few commands have disappeared. 2. There are no changes to adjust the vertical before and after a combination environment. Local patches can also be tricky because ConTeXt tries to freeze the definitions of many user level commands which means they can't be redefined when you use a strict overload mode (look at the lowlevel security manual for this feature). The most reliable way to center you combination blocks is to put them either in a float or put a framedtext environment around it. Wolfgang
