Executive Summary + +We will implement a centralized experiment flag system for jcode modeled after Codex's `codex_features` crate. The system introduces an `ExperimentFlag` enum with lifecycle stages (UnderDevelopment → Experimental → Stable → Deprecated → Removed), a TOML-based `[experiments]` config section for user toggles, CLI subcommands (`jcode experiment list/enable/disable`), runtime protocol API for TUI clients, and a checkbox list TUI popup. The system integrates into jcode's existing config layer (crates/jcode-config-types), CLI dispatch (src/cli/), protocol (crates/jcode-protocol), and TUI (crates/jcode-tui). This is a new `jcode-experiment-flags` crate plus modifications to 6 existing crates/modules. + +--- + +## 2.

Add jcode-experiment-flags crate with ExperimentFlag enum, EXPERIMENT_FLAGS static registry, Experiments runtime struct, Stage lifecycle (UnderDevelopment/Experimental/Stable/Deprecated/Removed) - Add [experiments] TOML config section via ExperimentConfig in jcode-config-types - Add CLI subcommands: jcode experiment list/enable/disable - Add protocol wire types: ExperimentList/ExperimentSet requests, ExperimentFlags server event - Add server-side protocol handler for experiment flag queries and mutations - Add TUI /experimental popup overlay with checkbox list (space toggle, enter apply, esc cancel) - Add experiment_popup module with ExperimentPopupState + ExperimentPopupAction - Register /experimental and /experiments commands in TUI - Add help overlay entry for /experimental - Wire key handling for popup in input.rs overlay chain - Add TUI state trait method + App struct field for popup - Config round-trips: save/reload preserves experiment states - Legacy key resolution for renamed flags - Dependency normalization, deprecation warnings, removed flag handling - 11 unit tests passing --- Cargo.lock | 63 ++- Cargo.toml | 3 + crates/jcode-app-core/Cargo.toml | 1 + .../src/server/client_lifecycle.rs | 24 + crates/jcode-base/Cargo.toml | 1 + crates/jcode-base/src/config.rs | 14 +- crates/jcode-base/src/config/env_overrides.rs | 25 + crates/jcode-config-types/src/lib.rs | 12 + crates/jcode-experiment-flags/Cargo.toml | 11 + crates/jcode-experiment-flags/src/lib.rs | 437 ++++++++++++++++++ crates/jcode-protocol/src/lib.rs | 2 + crates/jcode-protocol/src/wire.rs | 14 + crates/jcode-tui/Cargo.toml | 1 + crates/jcode-tui/src/tui/app.rs | 2 + crates/jcode-tui/src/tui/app/commands.rs | 35 ++ crates/jcode-tui/src/tui/app/input.rs | 31 ++ .../src/tui/app/state_ui_input_helpers.rs | 2 + crates/jcode-tui/src/tui/app/tui_lifecycle.rs | 2 + crates/jcode-tui/src/tui/app/tui_state.rs | 4 + crates/jcode-tui/src/tui/experiment_popup.rs | 168 +++++++ crates/jcode-tui/src/tui/mod.rs | 3 + crates/jcode-tui/src/tui/ui.rs | 12 + crates/jcode-tui/src/tui/ui_overlays.rs | 93 ++++ src/cli/args.rs | 26 ++ src/cli/dispatch.rs | 19 +- src/cli/experiment_flags.rs | 59 +++ src/cli/mod.rs | 1 + src/cli/proctitle.rs | 1 + 28 files changed, 1044 insertions(+), 22 deletions(-) create mode 100644 crates/jcode-experiment-flags/Cargo.toml create mode 100644 crates/jcode-experiment-flags/src/lib.rs create mode 100644 crates/jcode-tui/src/tui/experiment_popup.rs create mode 100644 src/cli/experiment_flags.rs diff --git a/Cargo.lock b/Cargo.lock index be5c1ef76..8cf5d4ef5 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -201,7 +201,7 @@ dependencies = [ "objc2-foundation", "parking_lot", "percent-encoding", -
