nimforum mirror - Tables and Import

Hello,

I am doing a simple test with tables and have problems using import.

I have a file Image.nim:

type
   Image* = ref object of RootObj
      filepath*: string

And a main file:

import tables
import Image

var imgTable: Table[string, Image]

imgTable["hello"] = Image(filepath: "world")

echo imgTable["hello"].filepath

When compiling I have the following issue:

main.nim(6, 9) Error: type mismatch: got <Table[system.string, void], string, Image>

Why my value type is recognized as void ? Image type seems to be recognized...

I am using nim 1.2.0

i think Image is first recognized as module. rename it to lowercase.

Yes it works that way, thanks!

But it is strange the type can be created but cannot be recognized in as the Table value type, isn't it ?

no, you named a module same way as another symbol, and module takes precedence. nothing to do with tables.

Ok, I also tried replacing this line:

var imgTable: Table[string, Image]

by this one:

var imgTable: Table[string, Image.Image]

And it still gives the same error.

Anyway I will change the module names

Module names seem to be lowercase by convention, and types uppercase.

I think try to make module names plural by convention as well, in the standard library the module containing Table is tables.

I would name the module images
