SYNTAX ERROR, how to parse prior probabilites in model block with likelihood

Modeling

Hi all, do you have an idea for this error?

SYNTAX ERROR, MESSAGE(S) FROM PARSER:
Probability function must end in _lpdf or _lpmf. Found distribution family = unif with no corresponding probability function unif_lpdf, unif_lpmf, or unif_log

166: model{
167: //prior distributions
168: b0 ~ unif(0.0,4.0);
^
169: b1 ~ unif(-0.1,0.1);

The distribution is called uniform(0.0,4.0) not unif(0.0,4.0).

Thank you. I really forgot to convert unif() into a C++ command.
