Loading symbols from simple files

Question

This file will be foo.pm6:

sub bar { "quux" }
say "Loaded";

And this one requirer.p6:

require "foo.pm6";

say bar;

require fails silently, not loading foo.pm6, and bar is not found. This also fails:

require foo;

say bar;

with the same error, about not finding bar. This file:

require ::"foo";

say bar;

Fails even strangely, with MVMArray: Can't shift from an empty array

UPDATE: it fails silently because it stops when it finds an unknown symbol, bar, so it's not running "It's loaded" before it produces the error. Still, the last error is weird.

Undeclared routine:
    bar used at line 9. Did you mean 'bag', 'VAR'?

So once that is out of the way, is bar actually imported? If it is, in which package name? How can I use it?

Answer 1

您可以使用lib将当前目录添加到库搜索路径。

如果我的补充export性状bar()在foo.pm6：

sub bar is export { "quux" }
say "Loaded";

以下似乎有效（requirer.p6）：

use v6;
use lib '.';
require foo <&bar>;
say bar;

输出：

Loaded
quux
