variant that accept generics Source   Edit  

func newProc(tup: tuple[name: NimNode, params: seq[NimNode]]; generics: NimNode;
             body = emptyn; procType = nnkProcDef; pragmas = emptyn): NimNode {.
    ...raises: [], tags: [], forbids: [].}

variant that accept generics, sleamless to work with parseSignature Source   Edit  

func parseBracketGenericParams(generics: var NimNode; params: NimNode): NimNode {.
    ...raises: [], tags: [], forbids: [].}

returns name Source   Edit

proc parseSignature(generics: var NimNode; signature: NimNode;
                    deftype = ident"untyped"): tuple[name: NimNode,
    params: seq[NimNode]] {....raises: [], tags: [], forbids: [].}

deftype is for both params and result, but if signature is of arrow expr, then restype will be its rhs. Source   Edit

    name: NimNode, params: seq[NimNode]] {....raises: [], tags: [], forbids: [].}
