From 54a71064f5330ea71529126d183584053086f6c0 Mon Sep 17 00:00:00 2001 From: twokidsCarl Date: Tue, 7 Apr 2026 21:19:40 -0700 Subject: [PATCH] Fix code review bugs, add 20 tests for edge cases Bug fixes from code review: - Fix missing return in handle_smart_input (MVU tuple broken) - Initialize @saved_input to prevent history navigation crash - Add rescue to InputHandler.completions (stale binding safety) - Add rescue to handle_tab_completion (never crash TUI) - Catch SystemExit in eval_ruby (user code calling exit) - Remove unused width param from StatusBar.build_right - Fix /source fallback condition (match all error types, not just "not found") - Wrap baseline_methods init in rescue 20 new tests (85 total): - Smart routing: NameError on single-word, string/array literals, MVU tuple - History: empty history, boundary, saved input preservation - Tab: empty prefix, no matches, slash command completion - /source: REPL-defined method fallback - eval_ruby: SyntaxError/NameError catch, success case - Baseline methods: new method detection - StatusBar: model name, scroll hint - /help: alignment, removed commands, hints Co-Authored-By: Claude Opus 4.6 --- lib/claw/tui/agent_executor.rb | 5 +- lib/claw/tui/input_handler.rb | 28 +++++--- lib/claw/tui/model.rb | 18 +++-- lib/claw/tui/status_bar.rb | 4 +- lib/claw/version.rb | 2 +- spec/claw/tui/model_spec.rb | 117 +++++++++++++++++++++++++++++++-- spec/claw/tui/snapshot_spec.rb | 46 +++++++++++++ 7 files changed, 195 insertions(+), 25 deletions(-) diff --git a/lib/claw/tui/agent_executor.rb b/lib/claw/tui/agent_executor.rb index 55a5d84..d3a1d63 100644 --- a/lib/claw/tui/agent_executor.rb +++ b/lib/claw/tui/agent_executor.rb @@ -92,10 +92,13 @@ def execute(input, binding, &on_event) # @param code [String] Ruby code to eval # @param binding [Binding] caller's binding # @return [Hash] { success: bool, result: Any, error: Exception? } + # Evaluate Ruby code in the given binding, catching all eval errors. + # Note: SyntaxError/ScriptError inherit from Exception (not StandardError), + # and SystemExit can be triggered by user code calling `exit`. def eval_ruby(code, binding) result = binding.eval(code) { success: true, result: result } -
