CLI: Editor GUI always opens when using `--compile` flag

[chances]

I'm invoking the CLI: sanny.exe --no-splash --mode gta3_sbl --compile main.txt

However, the editor GUI always opens.

Apparently, the CLI doesn't support relative paths. When I supply an absolute path, the GUI flashes on the screen. This is unintuitive and not in keeping with common behavior of other CLIs.

Expected Behavior

The program should compile the given script, or fail, without opening the GUI.

The --compile flag ought support relative paths, given my current working directory.

Environment

OS: Windows 10 Home 22H2 19045.7184
Sanny Builder version: 4.2.0

[chances]

Turns out, the user must use the full path to the script. For example:

C:\Users\%USERNAME%\Documents\GTA 3\Projects\[REDACTED]\main.txt

Even then, the GUI still flashes on the screen.
