//! Tauri command for launching the Python `command_builder` GUI.
|
||
|
|
//!
|
||
|
|
//! The Python fork ships a separate yaml-editing tool at
|
||
|
|
//! `python/tools/command_builder/` (a pywebview-based GUI). Without a launcher
|
||
|
|
//! button in the main Tauri GUI the user has no easy way to find it.
|
||
|
|
//!
|
||
|
|
//! Resolution order for the python checkout:
|
||
|
|
//! 1. `JARVIS_PYTHON_DIR` env override
|
||
|
|
//! 2. Sibling `python/` directory next to this jarvis-rust checkout
|
||
|
|
//! 3. `C:\Jarvis\python` (the dev box default)
|
||
|
|
//!
|
||
|
|
//! We don't ship the Python fork inside the Rust binary — this launcher just
|
||
|
|
//! tries to spawn it. If Python isn't installed, we open the docs URL instead.
