generics not working in external modules

[amalshaji]

V version: V 0.1.21 753fe32
OS:
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Codename: bionic

What did you do?
Wrote a sorting function using generics. Worked fine. Made the same function into a module and builds fine. Returns funny error when using the library

What did you expect to see?
Correct Output.

What did you see instead?
test.v:6:24: unexpected token: ,
5| fn main() {
6| nums := [1, 7, 0, 5, 6, 3]

Can you show the whole code?

[amalshaji]

Module code Code: bubble_generic_module.v
working code : bubble_generic.v

[medvednikov]

works for me

$ v run bu.v
[0, 1, 3, 5, 6, 7]

[amalshaji]

Module is working fine? For me bubble_generic.v is ok, but bubble_generic_module.v is not running after the module is imported in another file.

@medvednikov It works only with all code in single file. Try to compile with the module.

import sorty

fn main() {
	mut nums := [1, 7, 0, 5, 6, 3]
	sorty.bubble(nums)
	println(nums)
}

This gives an error:

test1.v:6:19: unexpected token: `,`
    5| fn main() {
    6| 	mut nums := [1, 7, 0, 5, 6, 3]
             	           ^
    7| 	sorty.bubble(nums)
    8| 	println(nums)

Concerning the mutability of the immutable array - this works because of the line in the function bubble<T>(nums []T)

mut var := nums

And then modifying var also modifies nums - but should not, because nums was not declared mut.

Another interesting note. I put the module code in the file sorty/sorty.v and tried to compile it accidentally missing module in the compile comand. And that's what I got:

code/v % v build sorty
V error: function `main` is not declared in the main module

I did not do anything with module main, file sorty.v starts withmodule sorty.

[medvednikov]

Fixed.
