[Acceleo] Circular dependencies [message #1808778]

Looking for the forum, it is assumed that Acceleo does not support cyclic dependencies (e.g., tmplA imports tmplB and vice versa). However, some of my templates do have circular dependencies and everything is working as expected.

Actually, there is one small thing: sometimes when I'm typing in some file, suddenly appear compilation errors (or warning?) about circular dependencies / recursive imports. Such errors disappear when I save the current file. Is it supposed to happen? I'm a little confused.

Hi

Circular imports can work. Circular inheritance cannot. Whether circular imports actually work is down to the diligence of the developer.

(IMHO in plausible declarative contexts, the actual imports are the transitive closure of the imports. It is only in nightmare macro contexts such as the C preprocessor that include guards are mandatory for consistent functionality.)
