transform extensions actions to commands - #241
Conversation
📝 WalkthroughWalkthroughThe extensions module replaces execution-point registration with extension and command registers. Extension manifests now use extension URI/query types, string contexts, and persisted enabled-state configuration. Commands and command states are generated from manifests and updated through registry notifications. The provider and QML models delegate extension discovery and enablement to the registry. Legacy plugin URIs and manifest parsing use the extension scheme. Dynamic legacy UI actions are disabled. API singleton ownership is set explicitly, and header directive formatting is normalized. Merge Risk: 🟠 High · up to This change can hide failed extension commands, disable previously configured extensions after upgrade, lose enablement changes when persistence fails, and leave the enablement control showing stale state. The PR is not merge-ready until these correctness and migration issues are fixed. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Return the extension execution result.
At Lines 66-68, onExtensionTriggered() discards provider()->perform(q) and always returns make_ok(). If a form cannot open or a macro fails to load or run, the command dispatcher receives success.
Return the provider result on the enabled path.

Refresh extension command states after manifest reload.
Subscribe to manifestListChanged() and call updateCommandStates() after reload. The command-register unreg()/reg() sequence does not refresh CommandsState or invalidate its cache, so changed manifest contexts can leave stale states.

Migrate the previous config.json schema before reading enabled.
This branch handles every existing extension config.json, but it assumes the new enabled field exists. The previous schema stored action and execution-point configuration. For those files, Line 148 reads a missing field as false, which disables previously configured extensions after upgrade.
Detect the previous schema and convert its effective manifest enabled state to ExtensionConfig::enabled. Add migration tests for existing extension configurations. The legacy-plugin migration in Lines 180-204 does not cover this file format.

Commit the enabled state only after the configuration write succeeds.
Line 116 changes m_configs before setExtensionConfigs() returns. Line 117 ignores a failed Ret. The registry then sends enabledChanged for a state that will revert after restart.
Write a copy of the map first. Assign it to m_configs and notify consumers only after persistence succeeds.
