stdlib import suggestions

[Akuli]

I just got this error

compiler error in file "../grid.jou", line 32: function 'strdup' not found

Would be nice if these errors suggested where to import the function from, e.g. function 'strdup' not found, consider importing "stdlib/str.jou"

I have a idea. We can use syntax like C/C++.
For example:

import <str.jou>  # This will import from stdlib
import "test.jou" # This will import at local

This syntax has some advantages

• Write less words
• If there is a filename as same as the filename in stdlib, you can import them all
• Less check

If we can remove .jou suffix, it will be nicer

I have considered this in the past, and decided to do what Jou does now, for a few reasons:

• import "stdlib/test.jou" is easier to parse, because it is just a keyword and a string
• I want Jou users to look in the stdlib/ folder, and if the import mentions stdlib/foo.jou, it is very obvious what file it is importing and from where
• In the future there might be a libs or deps folder where third-party dependencies of your project go. Then you would do import "libs/joujson/json.jou". In C/C++, < is confusing because it can mean standard library or third-party.

And here's why imports have the .jou suffix:

• It makes it obvious to users what the import does, and how to find the file being imported
• It simplifies the compiler (though only a little bit)

Hmm, alright, just a idea.

I should document imports, and explain in docs why they are like they are :)

I don't know personally, this always felt like too much automagic.
