YAMLicious is a small YAML reader/writer inspired by Thoth.Json syntax!

Code examples

F# Model

type Package = {
 Name: string
 Version: string option
}

type ArcValidation = {
 ArcSpecificationVersion: string
 Packages: Package list
} 

YAML

arc_specification: 2.0.0-draft
validation_packages:
 - name: package1
 version: 1.0.0
 - name: package2
 version: 2.0.0
 - name: package3

Decode (from YAML)

// from yaml
let Example1 = 
 "arc_specification: 2.0.0-draft
validation_packages:
 - name: package1
 version: 1.0.0
 - name: package2
 version: 2.0.0
 - name: package3"

let packageEncoder : (YAMLicious.YAMLElement -> Package) = 
 Decode.object (fun get ->
 {
 Name = get.Required.Field "name" Decode.string
 Version = get.Optional.Field "version" Decode.string
 }
 )

let arcValidationDecoder : (YAMLicious.YAMLElement -> ArcValidation) =
 Decode.object (fun get ->
 {
 ArcSpecificationVersion = get.Required.Field "arc_specification" Decode.string
 Packages = get.Required.Field "validation_packages" (Decode.list packageEncoder)
 }
 )

let actual : ArcValidation = Examples.ValidationPackageTypes.string |> Decode.read |> arcValidationDecoder

Encode (to YAML)

// to yaml
let Example2 = {
 ArcSpecificationVersion = "2.0.0-draft"
 Packages = [
 { Name = "package1"; Version = Some "1.0.0" }
 { Name = "package2"; Version = Some "2.0.0" }
 { Name = "package3"; Version = None }
 ]
}

let packageEncoder (pack: Package) = 
 [
 "name", Encode.string pack.Name
 Encode.tryInclude "version" Encode.string pack.Version 
 ]
 |> Encode.choose
 |> Encode.object

let arcValidationEncoder (arc: ArcValidation) = 
 Encode.object [
 "arc_specification", Encode.string arc.ArcSpecificationVersion
 "validation_packages", Encode.list packageEncoder arc.Packages
 ]

let actual : string = Encode.write 2 (arcValidationEncoder Example2)

Local Development

Requirements

Because this library targets multiple programming languages we need to support all of them:

• nodejs and npm
  • verify with node --version (Tested with v20.10.0)
  • verify with npm --version (Tested with v9.2.0)
• .NET SDK
  • verify with dotnet --version (Tested with 10.0.100)
• uv
  • verify with uv --version (Tested with 0.9.13)

Setup

This needs to be done on a fresh download once. Paths for python venv executable might be different depending on the OS.

1. dotnet tool restore, Restore .NET tools (fable)
2. npm i, install js dependencies
3. uv python install, install python itself if needed
4. uv pip install, install python dependencies

Testing

First activate python virtual environment (.\.venv\Scripts\Activate.ps1).

.\build.cmd test

or specify target

.\build.cmd test [f#, c#, js [native], py [native]]

Publish

Requires API keys for Nuget and PyPi.

The following command will run all tests, bundle and then start publishing!

.\build.cmd publish pipeline

or only publish specific targets, without test and bundle

.\build.cmd publish [npm, pypi, nuget]
