From b9fbcd43a25fbb1f9f3e5249bc584fa49b118f27 Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Wed, 22 Apr 2026 09:40:30 +0200 Subject: [PATCH] implement builtin.claude per D-041 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tier-0 stub flipped to the real Claude pane. Primary-per-repo semantics: session name is `clide-claude-` where is FNV-1a over the workspace root path, so reopening clide attaches to the same `claude` process through `tmux new-session -A`. Primary has no close button — closing the tab disposes the widget but deliberately does NOT call pane.close, so the tmux session survives until the user actually exits claude or clide is shut down. Secondary sessions (spawned via the claude.new-secondary command registered here, UI wiring lands next) close normally and the pane.close cascades into tmux kill-session. Graceful fallback when tmux isn't on PATH: retries the spawn with argv=['claude'], surfaces "no-tmux · fresh every launch" in the header subtitle so the user knows persistence is off. Session-naming unit tests cover determinism + uniqueness per repo. Full app suite: 174 tests passing.
