From a368dc53b82b3050091a4a98f1c778cd278513e0 Mon Sep 17 00:00:00 2001 From: Hunter Bown Date: Sun, 3 May 2026 06:36:37 -0500 Subject: [PATCH] feat(commands): /hooks read-only lifecycle hook listing (#460 MVP) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Slash command enumerates configured lifecycle hooks from the user's `[hooks]` table, grouped by event. The full picker / persisted enable-disable surface in #460 is still M-sized work; this MVP gives users a no-typing view of what's actually loaded — the most-asked question once hooks start firing. Implementation: * `crates/tui/src/commands/hooks.rs` formats the hook list with per-event headings, hook name (or `(unnamed)`), background marker, timeout, condition summary, and a 60-char shell command preview. * `condition_summary` covers every `HookCondition` variant (Always/ToolName/ToolCategory/Mode/ExitCode/All/Any) so the listing stays informative for compound conditions too. * `event_label` maps each `HookEvent` to its config-file string so the listing matches what the user wrote in TOML. * New `HookExecutor::config()` accessor exposes the underlying `HooksConfig` for read-only callers; doesn't open the door to mutation, which still belongs to the broader #460 work. * Registered in `commands::COMMANDS` with `aliases: &["hook"]`, usage `/hooks [list]`, and `MessageId::CmdHooksDescription` localized in en, ja, zh-Hans, pt-BR. * Wired into `command_palette::command_runs_directly` so pressing Enter from Ctrl+K runs `/hooks list` straight. Tests: 6 unit tests covering preview-cap truncation, newline stripping, condition-summary variants, event-label exhaustiveness, and BTreeMap-grouping ordering. --- CHANGELOG.md | 9 + crates/tui/src/commands/hooks.rs | 250 ++++++++++++++++++++++++++ crates/tui/src/commands/mod.rs | 8 + crates/tui/src/hooks.rs | 7 + crates/tui/src/localization.rs | 10 ++ crates/tui/src/tui/command_palette.rs | 1 + 6 files changed, 285 insertions(+) create mode 100644 crates/tui/src/commands/hooks.rs diff --git a/CHANGELOG.md b/CHANGELOG.md index ab08b14a..1f76ee65 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -219,6 +219,15 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 dropped.
