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:
import typer
def main():
print("Opening Typer's docs")
typer.launch("https://typer.tiangolo.com")
if __name__ == "__main__":
typer.run(main)
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
:
from pathlib import Path
import typer
APP_NAME = "my-super-cli-app"
def main():
app_dir = typer.get_app_dir(APP_NAME)
app_dir_path = Path(app_dir)
app_dir_path.mkdir(parents=True, exist_ok=True)
config_path: Path = Path(app_dir) / "config.json"
if not config_path.is_file():
config_path.write_text('{"version": "1.0.0"}')
config_file_str = str(config_path)
print("Opening config directory")
typer.launch(config_file_str, locate=True)
if __name__ == "__main__":
typer.run(main)
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
