typer VS cobra

I have been using Typer on every one of my CLI projects which uses Click under the hood. The documentation is fantastic, the CLI app it produces looks great and lets you create things quickly. I high recommend it.

Adding CLI capabilities. My preferred library here is typer.

I just heard about this but it seems to be pretty much the type of thing you want and want fast.

Docstrings are for documenting how a function/ class/ method/ module works. Often you don't need to add a docstring to your main function because no one will be importing it to use elsewhere. And if you want it to run as a CLI, then there are better ways to document the available options. For example, typer does most of it for you, or in click you add the help text to the decorator.

Most computing tasks in airflow DAGs are KubernetesPodOperator containing a CLI (Python Typer). It allows us to pass arguments easily to run DAG manually if needed (the new UI to pass arguments to DAG in airflow 2.6 is really nice). Arguments allow us to replay DAG easily (change start / end dates for instance).

So it's basically the main .gitlab-ci.yml file plus a separate Python CI app using Typer for the AWS instrumentation.

Similarly for Typer, which is literally "the FastAPI of CLIs"[1]. Handy to type your `main` parameters and have CLI argument parsing. For more complicated cases, it's a wrapper around Click.

interesting that you hate python, but love Click. Did you try Typer which uses Click underneath?

We can use the flag with --date or -date, Go already does the automatic check. We can make our entire boilerplate with this approach, but let's make it a little easier and use the Cobra CLI package.

In this tutorial, we'll walk through the process of creating a simple command-line tool similar to curl using Go and Cobra, a CLI library for Go.

I use https://github.com/spf13/cobra religiously for this kind of thing - it handles all the annoying corner cases of parsing flags, and also has an intuitive notion of subcommands (with basic usage/help text generated) for picking which task you want to run with positional arguments.

We recently chose cobra[1] to create a cli application. It comes with so many best practices already packaged like autocompletions, help texts etc. etc.

I looked at the docs: https://cobra.dev/ ... and there are only examples on how to add new flags.

For installing Cobra-CLI you can go to Cobraor run go install github.com/spf13/cobra-cli@latest in the terminal.

In my build phase, I compile the source to create a k3sup binary and I also run the binary to generate shell script completions. Give kudos to this functionality which comes from spf13/cobra Go library for CLIs.

NWA is a command-line tool built on cobra. Here's an overview of NWA's commands:
