Example Code

import typer


@app.command()
def hello(name: str):
    """Say hello to NAME."""
    typer.echo(f"Hello {name}")

@app.command()
def goodbye(name: str):
    """Say hello to NAME."""
    typer.echo(f"Hello {name}")


print("""This program can say hello or goodbye. To say hello to someone type hello + the name of the person
To say goodbye to someone type goodbye + the name of the person""")
command = input("What do you want to do? ")

# now let typer handle the input in command. I don't know how to do this, but I think something like this:
typer.run(command)  # I read the docs, so I know this won't work, but I want typer to handle the input as if it was run from the command line.

Description

Basically I want to make some kind bash shell in python with typer to parse the commands, provide help pages, etc. In the code you can see an example of what I mean. I know you can pass a command with CliRunner but that gives problems with promt() and then I still have to do some parsing myself. I think I found something similar here but I don't think this is what I want. If it is then I definitely don't know how to implement it :)

So my question is if this (processing strings and executing and everything) is possible with typer.
If not do you know a module or something else that I can use?

Thanks in advance
