edef,xdefwork here, I thought it was a full expansion, and indeed before (my version control is nigh absent so I can't give a mwe for this) it worked. - What is the significance of robustness? Is there a simple rule of thumb when it's necessary, obligatory, or irrelevant?
- It working with
xstring'sIfStrEqualonly if theis inserted in the definition ofdatemacro, rather than in the comparison's brackets, i.e.,{datemacro }. Why?
ifstrequalsupposedly doesn't expand- I used once in a command to test if an arguments is equal to&, this works- is #1 becoming whatever was input not count as an expansion?
