Define two binaries for compiler and deprecate futil in favor of calyx

[rachitnigam]

Long term, we're going to remove the default futil binary and replace it with calyx. This builds both and generates a warning any time you use the futil binary. If things start breaking for you, especially with fud, try running the command:

fud c stages.futil.exec "$(pwd)/target/debug/calyx"  

This will update fud to use the new calyx binary.

random q: are we planning to change the file extension type (name)? Could fight with calendars using .cal or with a document processor using .lyx, could use .cx (shockingly might actually be largely unused), .clx to conflict with adobe products??? apparently, or the long .calyx

[rachitnigam]

I was hoping to do that in the future but it is a large-ish change. I was thinking of .yx but .cx wouldn't be too bad? The only problem is that its too close to cxx which reminds people of terrible language

[sampsyo]

Wow; how exciting! This has been a long time coming!

.yx is very cute. I also really don't mind the fully-spelled-out .calyx.

[EclecticGriffin]

I am also a fan of .yx, but truly any of these would be fine

In this vein, would you consider renaming the fud invocation too? Only if it's easy.

The guide is currently forced to go like, "to compile to Calyx, pass the --to futil flag." and that's just a tiny bit annoying.

We can take a look but that might be a big breaking change. Can you open a new issue for this?
