Add python example

[rakeshksr]

cargo-packager working well with python projects with combination of pyinstaller. Adding python example will significantly benefit to python developers for packaging their python projects.

Hi @rakeshksr , I don't think we are currently planning to add Python support to the Cargo Packager.

Thank You

I'm interested in the same thing. If it has beforePackageCommand, all we need is to point the packager to execute the right exe in the right location. it would be awesome to add example for it or at least some inputs here.

@thewh1teagle, Packager.toml of my python project

name = "<project name>"
product-name = "<Long Name>"
version = "1.0.0"
authors = ["<author name>"]
publisher = "<publisher name>"
binaries = [{ path = "<main binary path>", main = true }]
identifier = "com.project.name"
before-packaging-command = "pyinstaller --clean --onefile --windowed --name <name> --add-data src/<name>/assets:assets --icon src/<name>/assets/app_icon.png src/<name>/__main__.py"
out-dir = "dist/bin"
binaries-dir = "dist"
icons = ["src/<name>/assets/app_icon.png"]
