# Find a working Python 3 interpreter and exec the hook with it.
|
|
#
|
|
# On Windows + Git Bash, `python3` typically resolves to the Microsoft Store
|
|
# stub at C:\Users\<user>\AppData\Local\Microsoft\WindowsApps\python3, which
|
|
# exits 49 silently in non-TTY subprocess context (a known Microsoft Store
|
|
# stub behavior). This shim
|
|
# probes each candidate with `-c ""` and skips any that fails, so the Store
|
|
# stub falls through to the real python.org install (`python` in Git Bash) or
|
|
# the `py -3` launcher.
|
|
#
|
|
# Order:
|
|
# 1. python3 — canonical on macOS/Linux; the Store stub fails the probe.
|
|
# 2. python — python.org installs on Windows; some Linux distros (RHEL 7
|
|
# EOL'd 2024-06) point this at Python 2, but `-c ""` succeeds
|
|
# on Python 2 too — guard with a version check.
|
|
# 3. py -3 — Windows Python launcher.
|
|
#
|
|
# Args after the shim path are passed straight through to the chosen
|
|
# interpreter, so the hooks.json invocation is:
|
|
# bash "${CLAUDE_PLUGIN_ROOT}/hooks/sg-python.sh" \
|
|
# "${CLAUDE_PLUGIN_ROOT}/hooks/security_reminder_hook.py"
|
|
set -e
|
|
|
|
probe() {
|
|
# $1..N: the interpreter command (may be multi-word like `py -3`)
|
|
# Probe writes the major version to stdout and exits 0 iff it's >=3.
|
|
"$@" -c 'import sys; print(sys.version_info[0])' 2>/dev/null
