Launching Applications

You can launch applications from your CLI program with typer.launch().

It will launch the appropriate application depending on the URL or file type you pass it:

{ docs_src/launch/tutorial001.py hl[6] }

Check it:

$ python main.py

Opening Typer docs

// Opens browser with Typer's docs

Locating a file

You can also make the operating system open the file browser indicating where a file is located with locate=True:

{ docs_src/launch/tutorial002.py hl[17] }

/// tip

The rest of the code in this example is just making sure the app directory exists and creating the config file.

But the most important part is the typer.launch(config_file_str, locate=True) with the argument locate=True.

Check it:

$ python main.py

Opening config directory

// Opens a file browser indicating where the config file is located
