  The home of the CUE language! Validate and define text-based and dynamic configuration

  

  I've been somewhat surprised that CUE bills itself as "tooling friendly" and doesn't yet have a language server- the number one bit of tooling most devs use for a particular language.

  I'm assuming it's becaus CUE is still unstable?

  Anyway, if others are interested in CUE's LSP work, I think https://github.com/cue-lang/cue/issues/142 is the issue to subscribe to

• dhall-lang

  118 4,232 5.0 Dhall

  Maintainable configuration files

  

  Well, Dhall provides something between JSON and a Turing complete language that can make a lot of configuration much quicker to write, if you can hack the functional syntax.

• starlark

  25 2,502 3.8 Starlark

  Starlark Language

  

  Trivia note, the bazelbuild starlark readme example shows a rare correct implementation of FizzBuzz, with no unique case for "FizzBuzz".

• Graal

  165 20,453 10.0 Java

  GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

  

  Pkl was built using the GraalVM Truffle framework. So it supports runtime compilation using Futurama Projections. We have been working with Apple on this for a while, and I am quite happy that we can finally read the sources!

• pkl-go

  3 269 8.0 Go

  Pkl bindings for the Go programming language

  

  sadly the Go implementation is bloated as hell:

  no thank you.

  Extensible Data Notation

  

  > was utterly surprised how no one ever apparently has thought to create a configuration/templating system that's basically a fancy library on top of Scheme.

  There's Clojure's extensible data notation: https://github.com/edn-format/edn

• pkl-pantry

  2 238 8.4 Pkl

  Shared Pkl packages

  

  More poking around in this; it'd be great if things like

  https://github.com/apple/pkl-pantry

  Had more documentation. Like there's a prometheus template; is that for use only in k8?

• copybara

  14 2,169 9.1 Java

  Copybara: A tool for transforming and moving code between repositories.

  

  Step two of installing Copybara is to install Bazel [0], so that doesn't exactly contradict my claim that if you're not already using Bazel you probably won't use Starlark.

  This repository contains example applications to illustrate the different capabilities of GraalVM

  

• cel-spec

  16 2,934 8.2 Starlark

  Common Expression Language -- specification and binary representation

  

  My employer uses a combination of Protocol Buffers (for the config schema definition) and Bazel/Starlark (for concrete instantiations). Configs are validated at build time and runtime using CEL (https://github.com/google/cel-spec).

• simplelanguage

  6 614 2.0 Java

  A simple example language built using the Truffle API.

  

  Truffle has no opinion on how you parse the sources. It cares about how you execute them from an intermediate Truffle guided representation produced by the parser.

  In other words antlr and truffle are a great fit. We even use this pairing for our example language simplelanguage.
