❔ Default command in System.CommandLine

I'm using System.CommandLine for a little CLI, and I want two commands: compile and run. What I want is for the user to be able to just do myapp path/to/some.file which would invoke compile by default, but also be able to do myapp run path/to/some.file, in a similar vein to how dotnet path/to/some.file is just dotnet exec path/to/some.file. How do you do this?

isn't System.Commandline, like, pretty crap at the current state can't you just register the same handler for both the root command and the subcommand?

I used to use it but moved away to Spectre, but I digress

Yeah I've been given this recommendation from someone on the System.CommandLine repo, I'm gonna have to investigate it

Spectre is nice although I prefer how much more extensive System.CommandLine is Granted it's still in beta

I see Yeah, something that makes me stop using it now is that I think there's some work going on in the main dotnet/runtime repo in the same namespace so I'm afraid if things will massively change compared to the package already released now which is, imo, not a bad thing, but I don't want to rewrite stuffs afterwards >.>

I'd be happy if it was merged into the BCL

Yeah. It's something I feel like quite a gap that the current BCL is missing, something that does command line handling and stuffs

It's kind of funny how many CLI libraries there are

I mean, it's not necessarily a bad thing, because competition and all I find it somewhat funny how .NET people always ask "why dis is not in the BCL already ree" compared to Node / Python where people never seem to mind adding all sorts of dependencies for all the things Not that it's bad. I get why it is the case, just interesting how people think differently

I mean, .NET is kind of spoiled in terms of its BCL It's massive and has a ton of things out-of-the-box

Yeah it's very nice having things out of the box and something that has good guarantees about its future, unlike many open source libraries run by people in the free time & may not necessarily be maintained for long
