Add environment variable support for modules (#331) * Add 'expor env' dummy command * (WIP) Abstract away module exportables as Overlay * Switch to Overlays for use/hide Works for decls only right now. * Fix passing import patterns of hide to eval * Simplify use/hide of decls * Add ImportPattern as Expr; Add use env eval Still no parsing of "export env" so I can't test it yet. * Refactor export parsing; Add InternalError * Add env var export and activation; Misc changes Now it is possible to `use` env var that was exported from a module. This commit also adds some new errors and other small changes. * Add env var hiding * Fix eval not recognizing hidden decls Without this change, calling `hide foo`, the evaluator does not know whether a custom command named "foo" was hidden during parsing, therefore, it is not possible to reliably throw an error about the "foo" name not found. * Add use/hide/export env var tests; Cleanup; Notes * Ignore hide env related tests for now * Fix main branch merge mess * Fixed multi-word export def * Fix hiding tests on Windows * Remove env var hiding for now 2021-11-16 00:16:06 +01:00			`use crate::{BlockId, DeclId};`
