From 76338c5220da0fccf230e99dd0238d4095b4cd3b Mon Sep 17 00:00:00 2001 From: Tim Visher <194828183+timvisher-dd@users.noreply.github.com> Date: Sun, 15 Mar 2026 14:33:56 -0400 Subject: [PATCH 01/65] Add CI workflow and local test runner CI workflow runs byte-compilation and ERT tests on push/PR using GitHub Actions with deps checked out from timvisher-dd/acp.el-plus and xenodium/shell-maker. bin/test parses ci.yml with yq so local runs stay in sync with CI automatically.

In GUI mode on macOS, uses native UNUserNotificationCenter via a dynamic module (agent-shell-alert-mac.dylib) compiled JIT on first use (inspired by vterm). When compilation fails (e.g. missing Xcode CLI tools), a message recommends `xcode-select --install`. In terminal mode, auto-detects the host terminal emulator and sends the appropriate OSC escape sequence: - OSC 9: iTerm2, Ghostty, WezTerm, foot, mintty, ConEmu - OSC 99: kitty - OSC 777: urxvt, VTE-based terminals Inside tmux, wraps in DCS passthrough (checking allow-passthrough first). Falls back to osascript on macOS when the terminal is unknown or tmux passthrough is not enabled.

Since `kill-buffer` will have the effect of changing the default directory to the "other buffer", `agent-shell--start` can possibly end up creating the new shell an unexpected project (e.g if the user's last buffer was in a different project, the new shell will be made for this project instead of the expected behavior of being for the same project the original shell was for). The fix is to bind `default-directory` around calling `agent-shell--start`, since this will retain the default directory across the `kill-buffer` call. `agent-shell-reload` was also affected, since it delegates to `agent-shell-restart`. A new test is added to ensure that, in a frame whose last buffer was another project than the current shell's, calling restart will still use the shell's project as expected. Without the fix, the test fails.

This is common on macOS (e.g., Menlo at `:height 120`). The 0 propagates into the SVG `` elements as `font-size="0"`, rendering all header text invisible while the icon still displays. Fall back to `frame-char-height` when `font-get :size` returns 0.
