Update Log

v1.2.2

- Generate minimal workspace Cargo.toml with only the script being built and dependencies folder
- Prevents build failures when workspace Cargo.toml references projects that no longer exist

v1.2.1

- Fixed error detection: Added catch-all error pattern to catch cargo workspace errors like "error: failed to load manifest"
- Previously only matched specific error patterns, causing silent failures for cargo-level errors

v1.2.0

- Build log verification — After rebuild completes, automatically downloads and scans the build log for compilation errors
- Prominent error display — Shows a big red BUILD FAILED block with all error lines when compilation fails
- Clean failure handling — No more confusing success messages after failure; exits cleanly without noisy traceback
- Automatic cleanup — Log files are always deleted after inspection, even on failures
- File locking — Prevents multiple terminals from running builds simultaneously (cross-platform: Windows msvcrt, Unix fcntl)
- Queue-aware waiting — If another build is running, displays a clear message and polls every 3 seconds until the lock is released
- Automatic lock release — Uses atexit to ensure locks are cleaned up on normal exit, crashes, or Ctrl+C
- Option 0 — Interactive menu now shows 0. Build ALL scripts at the top
- CLI support — python osbot_auto_build.py all builds all scripts sequentially
- Sequential processing — Each script goes through the full cycle (package → upload → rebuild → verify → download) before the next starts
- Login once — Authenticates once and reuses the session for all scripts
- Per-script sections — Clear headers like Building script 1/3: script_name when building multiple
- Correct DLL download — Fixed bug where the most recently modified script was downloaded instead of the one actually built (e.g., selecting thieving but getting magic)
- Added version constant VERSION = "1.2.0" displayed in the configuration header as OSB Builder Automation v1.2.0

v1.1.0

- Added file lock mechanism to prevent concurrent instances
- Added "Build All" option (0) to run all scripts sequentially
- Fixed an issue with credentials on Windows

v1.0.0

- Initial release

--- WHAT IT DOES ---

Run one command and it will:

- Package your script + dependencies + Cargo.toml into a ZIP

- Upload it, trigger a rebuild, and wait for it to finish

- Download the compiled DLL into compiler/downloads/

- Clean up the temp ZIP when done

--- SETUP ---

1. Extract the compiler/ folder into your project root (same level as Cargo.toml):

   my_project/
   ├── Cargo.toml
   ├── script_dependencies/
   ├── my_script/
   └── compiler/

2. Install Python 3 if you don't have it:

Python Installation Steps

   - Windows: https://www.python.org/downloads/ (check "Add to PATH")

   - macOS: brew install python3

   - Linux: sudo apt install python3 python3-venv

3. Open a terminal in the compiler/ folder and run:

Terminal Commands

   python3 -m venv .venv

   # macOS / Linux

   .venv/bin/pip install requests colorama python-dotenv

   # Windows

   .venv\Scripts\pip install requests colorama python-dotenv

4. Copy .env.example to .env and fill in your credentials:

.env Credentials

   USERNAME=your_username

   PASSWORD=your_password

That's it. Everything else is auto-detected.

--- USAGE ---

From your project root:

Usage

   # macOS / Linux

   compiler/.venv/bin/python compiler/osbot_auto_build.py

   # Windows

   compiler\.venv\Scripts\python compiler\osbot_auto_build.py

If you have multiple scripts, it will show a menu. You can also pass the name directly:

   compiler/.venv/bin/python compiler/osbot_auto_build.py my_script

Your compiled DLL will be saved to compiler/downloads/.

--- NOTES ---

- Your source files are never modified or deleted

- Works on Windows, macOS, and Linux

- If a DLL already exists, it gets overwritten with the new build

- Do not share your .env file — it contains your credentials
