From d8a5faa01fdc8318cb6f4ac45e58f01d3f4ae8fe Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 3 Feb 2026 10:14:15 +0000 Subject: [PATCH 1/4] refactor: consolidate stdlib type checking logic into helpers Consolidated duplicate argument validation and type checking logic from various `stdlib` modules (`list.rs`, `text.rs`, `math.rs`, `time.rs`, `crypto.rs`, `filesystem.rs`) into a new `src/stdlib/helpers.rs` module. This reduces code duplication, standardizes error messages (e.g. for argument counts), and simplifies the implementation of native functions. Changes: - Created `src/stdlib/helpers.rs` with `check_arg_count`, `expect_number`, `expect_text`, etc. - Refactored `list.rs`, `text.rs`, `math.rs`, `time.rs`, `crypto.rs`, `filesystem.rs` to use these helpers. - Registered `helpers` module in `src/stdlib/mod.rs`.

This reduces code duplication, standardizes error messages, and fixes validation logic in `filesystem.rs` (panic on 0 args) and `time.rs` (restored variable argument support). Changes: - Created `src/stdlib/helpers.rs` with `check_arg_count`, `check_min_arg_count`, `expect_number`, `expect_text`, etc. - Refactored `list.rs`, `text.rs`, `math.rs`, `time.rs`, `crypto.rs`, `filesystem.rs` to use these helpers. - Fixed potential panic in `native_remove_dir` by adding missing argument check. - Restored support for variable arguments in `native_create_time`. - Updated `wflhash` tests to match standardized error messages. - Registered `helpers` module in `src/stdlib/mod.rs`.
