Quote the interpreter path when launching background services - #364
Merged
Conversation
`_start_sessions()` interpolates `sys.executable` into a shell command string
(it pipes to `tee`) that tmux runs via `/bin/sh -c`. A pipx install on macOS
lives under `~/Library/Application Support/...`, so the space word-split the
path and startup failed with:
zsh: no such file or directory: /Users/.../Library/Application
Wrap it in `shlex.quote`. Regression test covers both the service and runner
sessions.

Problem
macOS users who install panopticon via pipx get an interpreter path under
~/Library/Application Support/pipx/...— which contains a space. Starting the background services fails:Cause
terminal/__main__.py::_start_sessions()interpolatessys.executableunquoted into a shell command string (it pipes totee), then hands that string totmux new-session, which runs it via/bin/sh -c. The space in the path word-splits and the shell tries to exec the truncated first word.Fix
Wrap the interpreter path in
shlex.quote(sys.executable). Both loop entries (theserviceandrunnersessions) share the samepythonvariable, so the one change covers both. A regression test patchessys.executableto a space-containing path and asserts bothnew-sessioncommands carry the quoted path (parsing back to a single argv token).An audit of every other shell-execution / interpolation site in
src/found no further instances —console.py,local_runner.py,shell_runner.py, anddashboard.pyall pass argv lists or alreadyshlex.quotetheir inputs. Details in theplan.mdartifact.🤖 Generated with Claude Code
