How to define durations from variables is not obvious

[guillaumeFerard]

hello, it seems that it's not possible to use a variable to add months but only hard coded value

for example : i can't do birthday_date + nb_months month but only birthday_date + 2 month

its a problem because depending the situation the number of months can change.

Ah, it's a syntax issue: indeed n month is only allowed for constants. You can, however, write n * 1 month with a variable n 😄

ok thanks !

Keeping this open, as we should probably either

• add syntactic sugar to suport it
• document it more explicitely in book.catala-lang.org
