| 1 | #!/usr/bin/env bash |
| 2 | # Find a working Python 3 interpreter and exec the hook with it. |
| 3 | # |
| 4 | # On Windows + Git Bash, `python3` typically resolves to the Microsoft Store |
| 5 | # stub at C:\Users\<user>\AppData\Local\Microsoft\WindowsApps\python3, which |
| 6 | # exits 49 silently in non-TTY subprocess context (a known Microsoft Store |
| 7 | # stub behavior). This shim |
| 8 | # probes each candidate with `-c ""` and skips any that fails, so the Store |
| 9 | # stub falls through to the real python.org install (`python` in Git Bash) or |
| 10 | # the `py -3` launcher. |
| 11 | # |
| 12 | # Order: |
| 13 | # 1. python3 — canonical on macOS/Linux; the Store stub fails the probe. |
| 14 | # 2. python — python.org installs on Windows; some Linux distros (RHEL 7 |
| 15 | # EOL'd 2024-06) point this at Python 2, but `-c ""` succeeds |
| 16 | # on Python 2 too — guard with a version check. |
| 17 | # 3. py -3 — Windows Python launcher. |
| 18 | # |
| 19 | # Args after the shim path are passed straight through to the chosen |
| 20 | # interpreter, so the hooks.json invocation is: |
| 21 | # bash "${CLAUDE_PLUGIN_ROOT}/hooks/sg-python.sh" \ |
| 22 | # "${CLAUDE_PLUGIN_ROOT}/hooks/security_reminder_hook.py" |
