Use Source Generators to make Spectre.Console.Cli AOT compatible?

[mimeister]

Hi,
I recently learned that Source Generators are a thing and this got me thinking that they could be the key to make CLI argument parsing trimming- and AOT-friendly.
Neither did I take a deep dive into Source Generators, nor into the code of Spectre.Console.Cli, so I cannot tell, if this is actually possible. My gut feeling is that it is doable, but it probably requires big code changes.
Unfortunately I don't have the time to further look into this, but I wanted to share this idea anyway. Maybe someone wants to pick it up who's familiar with the code of Spectre.Console.

Best regards,
Michael

I started working on a source generator for completions, akin to dotnet complete.
For this some things would be really useful (e.g. having the TemplateParser public, not throwing in there but returning some kind of resultlist with errors etc.).
So even though i can't promise that i'll see this through to absolute completion, there might be some useful offspring either way (e.g. regarding the TemplateParser: an analyzer for the template strings).
Is this something that is of interest here? Mostly as a question towards the maintainers: should i work on this in a fork or would you rather like something like that to be completely external?
