mazzle VS click

I've been experimenting with alternative pipeline syntaxes.

One example is using Graphviz graph files as an execution plan for software deployments. You can see a graph here:

https://github.com/samsquire/mazzle/blob/master/docs/archite...

I wrote code with networkx to parse this graph dot file and then follow the plan topologically, spinning up packer, terraform, bash scripts, compilation and so on. It also executes graph nodes in parallel where it can.

I talk about it here https://devops-pipeline.com/

My problem with bash pipelines is passing data along and referring to previous steps' data. You kind of need to enrich the data that goes along the pipeline.

I use Graphviz dot syntax to configure entire cloud computing environments in the order they must be built. This is pipelines as code and infrastructure as code

It's very powerful! Not every organisation can bring up an entire environment with one command.

Here is a executable diagram of a build worker cloud nodes, Kubernetes, consul, vault, Debian package server, Java app, SSH bastion, Prometheus, grafana, DNS and security groups.

https://github.com/samsquire/mazzle/blob/master/docs/archite...

The tool also parallelises the build based on the graph so packer builds can run in parallel.

It also has a GUI but it's not ready for other people to use.

I use a tool I wrote to layer my infrastructure with layers called components and I configure it with a Graphviz file.

My tool, called mazzle (previously devops-pipeline) would run parts of the graph that can run in parallel in parallel. It can also run parts of the build on SSH workers. You bring up the workers at the beginning of the build.

Here's an example of a graph generated from graphviz file: https://github.com/samsquire/mazzle/blob/master/docs/archite...

This graph brings up a hashicorp vault server, Java application, bastion proxy etc.

here's the graphviz file: https://github.com/samsquire/mazzle-starter/blob/master/arch...

It describes the ordering of the infrastructure, the invocation of Ansible, packer, shell scripts to set up vault etc.

The idea is to be able to bring up a new environment by changing one parameter. There's a React GUI too.

Context: "click" - "Command Line Interface Creation Kit" - easily create CLIs from Python code, via adding decorators: https://github.com/pallets/click

"click-web" in turn turns the click CLI app into a web app with one line of code.

there is also click, it is more straight forward and also nice to keep the relevant code where the code is. https://github.com/pallets/click/

I don't have huge experience with Python, but I used async code with C#/Typescript and lately I had to use some asyncio magic.

I found this article: https://blog.dalibo.com/2022/09/12/monitoring-python-subproc... and while async/await syntax is the same, it's not entirely clear for me, why there's some event loop and what exactly happens, when I pass function to asyncio.run(), like here: https://github.com/pallets/click/issues/85#issuecomment-5034...

So, you can use it and it's not that hard, but there are some parts that are vague for me, no matter which language implements async support.

Hmm… did you try such approaches, as [click](https://github.com/pallets/click) or[tap](https://github.com/swansonk14/typed-argument-parser)?

This app leverages these powerful libraries: - yt-dlp: video downloader - moviepy: video trimmer/merger - click: CLI app creator - rich / rich-click: CLI app styler

I've used click [1] a lot to build Python tooling scripts the past few years. Click usage is "sort of" similar to the author's proposed solution. There's also a small section here [2] that describes some of the issues covered in the article (in context of argparse).

I think the success of Arduino in the hardware world can be explained in a similar way, as the relative success of "command line app frameworks" like Click[1], or even much lighter-weight libraries like argparse[2]. You absolutely can get away with using just getopt[3] (and people experienced with it will likely strongly prefer it). However certain factors such as a more declarative API, a nice logo, the existence of an ecosystem (even if you're not actively drawing from it), an official "branded" forum, etc can all play into picking a more complex solution, with more baggage you don't need, certain oddities that may throw users off, etc.

Exactly! You can also use a library like click (https://github.com/pallets/click) to help take care of the command line side, while you focus on the 'business logic' of your application :)
