dhall VS pyinfra

```

If you mean installing Dhall's dependencies (https://github.com/dhall-lang/dhall-haskell/blob/master/dhal...), those aren't too crazy, but they're definitely not all "beginner level". Template Haskell in particular is quite heavyweight.

Ok, lets be specific. Lets write a comment to explain this function:

https://github.com/dhall-lang/dhall-haskell/blob/master/dhal...

I haven't tried it but apparently you can compile to Nix from Dhall:

> You can use this compiler to program Nix using the Dhall language. This package targets people who wish Nix had a type system.

https://github.com/dhall-lang/dhall-haskell/tree/master/dhal...

If the problem is the syntax and people wants some other format that compiles to nix, there's dhall

https://dhall-lang.org/

https://github.com/dhall-lang/dhall-haskell/tree/master/dhal...

https://www.haskellforall.com/2017/01/typed-nix-programming-...

Dhall is a generic config language with some programming capabilities (but not turing complete) that can compile to json, yaml, and other formats, like in this instance nix.

For my GSoC project, I built from scratch the dhall-csv package on the Dhall Haskell implementation Github Repository. Said package provides two executables, dhall-to-csv (which converts Dhall files into CSV files) and csv-to-dhall (which converts CSV files into Dhall files). It also provides Haskell libraries with the functions that translate bidirectionally between Dhall and CSV.

> If you add constraints (like not being able to feed the program to itself as is done in the halting problem and not allowing unbounded loops) then it is possible to determine if a program will terminate or not.

Dhall is a good example - https://github.com/dhall-lang/dhall-haskell .

That just seems like an even greater nightmare to me. Soon you would have to learn to read and understand a custom program in a Turing-complete language for each and every installation.

The proper solution is a DSL, just a better DSl. Or perhaps a DSL embedded in something like dhall <https://dhall-lang.org/>, but definitely not a general-purpose programming language.

pyinfra – automates infrastructure using Python

There is https://pyinfra.com/

As a sidenote, I also made a small experiment a while ago : https://github.com/linkdd/tricorder/

But it's a bit of a chicken-and-egg problem. Without users, I don't know how it should be used, without features I won't get any users. So for now, it's in a state of "I'll address bug reports and feature requests, but I won't actively develop it".

I like https://github.com/pyinfra-dev/pyinfra. "pyinfra automates infrastructure using Python"

Only played with it for a little but it seems well designed an simpler alternative to ansible, chef and other such things.

Haven't used it in anger yet, but I have high hopes for PyInfra: https://github.com/pyinfra-dev/pyinfra

pyinfra - https://pyinfra.com/ - Pyinfra is simpler for me than Ansible. I completed the entire deployment in one afternoon, from installing and configuring the VPS server from scratch to deploying the application and automatically restoring the database from a backup.

I’ve replaced Ansible with PyInfra where ever possible. https://pyinfra.com/ is very clean, and fast but lacks the shear amount of automation that can be found with Ansible.

Some folks don't like YAML all that well, and I can understand where they are coming from. I wish Ansible provided a good Python API so that playbooks could be written in Python easier. But there is a project called PyInfra that is trying to do something similiar to Ansible, using Python as the configuration language. https://pyinfra.com/ It is still pretty new so not got nearly as many modules written for it yet.
