Vl-pps-expr

Pretty-print an expression into a string.

Signature
(vl-pps-expr x) → pretty-x
Arguments: x — Guard (vl-expr-p x).
Returns: pretty-x — Type (stringp pretty-x).

This pretty-prints an expression "as is," i.e., in its current, possibly transformed state. Depending on what you're trying to do, it may be better to use vl-pps-origexpr instead, which tries to print the "original," pre-transformed version of the expression, as it occurred in the real Verilog file.
