Walkthrough

The changes update README.md and backend/script.sh to improve Git Bash/Windows compatibility: they add Windows-specific README instructions, make the script detect OS, fall back from python3 to python, use the correct venv activation path on Windows, replace wget with curl -L, and fix virtualenv deactivation.

Changes

Cohort / File(s) Change Summary
Windows Compatibility Documentation
README.md
Added Windows-specific instructions: use python if needed, source venv/Scripts/activate for venv, and curl fallback for downloads.
Backend Setup Script OS Handling
backend/script.sh
Script prints OS, attempts python3 then python for venv creation, uses OS-aware activation (venv/bin vs venv/Scripts), replaces wget with curl -L -o, and updates deactivation to call deactivate guardedly.

Poem

In the burrow I code with a twitch of my nose,
The script now hops where the Windows wind blows.
python or python3, whichever will do,
curl brings the files, venv wakes up anew.
Hooray — cross-platform carrots for you! 🐇✨

1-2: Add strict-mode guards at the top of the script

set -euo pipefail (or at least set -e) will abort the script on the first failing command, preventing the rest of the logic (e.g., deactivate) from being executed in a half-configured environment.

 #!/bin/bash
+
+# Abort on error, undefined var, or failed pipeline
+set -euo pipefail

15-19: Pattern matching is fragile; simplify OS detection

Quoting the RHS while appending * works, but it is easy to get wrong and fails in POSIX /bin/sh. Since the script already requires Bash, prefer:

-if [[ "$OSTYPE" == "msys"* || "$OSTYPE" == "cygwin"* || "$OSTYPE" == "win32" ]]; then
+case "$OSTYPE" in
+  msys*|cygwin*|win32*)
   source venv/Scripts/activate
-else
+    ;;
+  *)
   source venv/bin/activate
-fi
+    ;;
+esac

This is shorter, more idiomatic, and avoids subtle quoting pitfalls.


25-27: Consider --fail and output file naming for curl

Adding --fail turns HTTP errors into non-zero exit codes that stop the script under set -e.

-  curl -L $S2V_URL -o $S2V_ARCHIVE
+  curl -fL $S2V_URL -o "$S2V_ARCHIVE"

Also quote variables to protect paths containing spaces.

46-51: Minor wording & consistency tweaks for the Windows note

  1. Replace “If using Git Bash:” with “When running in Git Bash:” to read more naturally.
  2. Clarify that the script already falls back to curl, so the user doesn’t have to do anything.
-### 🪟 Windows Users
-If using Git Bash:
+### 🪟 Windows Users
+When running in Git Bash:
 - Replace `python3` with `python` if needed.
 - Use `source venv/Scripts/activate` instead of `source venv/bin/activate`.
- - If `wget` is not available, `curl -L -o` is used in script.
+ - No action needed if `wget` is missing — the script automatically uses `curl -L`.

11-13: Use command -v for more reliable Python fallback

python3 -m venv venv || python -m venv venv only triggers the fallback if the first command exits non-zero. On some systems python3 may exist but point to Python 2 or have venv missing, returning exit 0 while still doing the wrong thing. A safer pattern:

-if [ ! -d "venv" ]; then
-  python3 -m venv venv || python -m venv venv
-fi
+if [ ! -d "venv" ]; then
+  if command -v python3 >/dev/null 2>&1; then
+    python3 -m venv venv
+  else
+    python -m venv venv
+  fi
+fi
