# staged-script
Python is an ideal language for certain types of infrastructure automation.
Automating what a user does manually often involves walking through a series of
stages. A user may wish to run all the stages in series, or perhaps only a
subset, and depending on how things go, certain stages may need to be retried.
Once the script finishes running, it'd be ideal if it could tell the user
exactly what was run, for the sake of easing replicability. `staged-script`
aims to ease the development such automation scripts. It's easy to get started
with, but also provides significant power-user functionality for those who need
it.
## Installation
To get up and running with `staged-script`, simply:
```bash
python3 -m pip install staged-script
```
## Usage
Once installed, you can simply
```python
import sys
from staged_script import StagedScript
class MyScript(StagedScript):
@StagedScript.stage("hello", "Greeting the user")
def say_hello(self) -> None:
self.run("echo 'Hello World'", shell=True)
@StagedScript.stage("goodbye", "Bidding farewell")
def say_goodbye(self) -> None:
self.run("echo 'Goodbye World'", shell=True)
def main(self, argv: list[str]) -> None:
self.parse_args(argv)
try:
self.say_hello()
self.say_goodbye()
finally:
self.print_script_execution_summary()
if __name__ == "__main__":
my_script = MyScript({"hello", "goodbye"})
my_script.main(sys.argv[1:])
```
For more detailed usage and API information, please see
[our documentation][docs].
