Pliant VS Textrude

Here is a GitHub workflow you can use as an example. It uses git tags as version numbers. https://github.com/patrickhuber/Pliant/blob/main/.github/workflows/pipeline.yml

Fair point - source generators can run arbitrary code so yes, they can read a json file and then spit out something else in response. If you want to translate the json schema into the equivalent C# you'll need to write a small amount of code to deserialize the json into a JObject tree, walk it, and emit c# code. I do something similar in my Textrude code-generation/templating project except I'm translating the tree into an equivalent Scriban object tree. The relevant source code is here. All that said, this is a fairly specialised and common task - I can't believe there's not a command line tool to do this already.

Plug for something I wrote: [github link]*https://github.com/NeilMacMullen/Textrude). The CLI version can pipe json (or yaml,csv or text lines) from stdin or fetch it from a URL then turn it into model and apply a Scriban template to it to emit text to stdout. Runs on Linux or Windows and also comes with an interactive UI prototyping tool.
