Support more lax version schemes

[FroMage]

1.0 or foo-beta for example. anything really

Does that mean that we will always have to specify versions? Because this "anything" schema means I could never say module foo, version 2.0+
Also when running from the command line it would be nice if you could just give the name of the module and it will assume you want the latest version.

[FroMage]

No idea, have to read the spec, but one thing experience shows is that number schemes are infinite, impenetrable and improperly used ;)

[gavinking]

Currently we do not support version ranges. At some stage in the future I suppose there will be a lot of pressure to do so, but for now it's easier to just not open up this can of worms.

[FroMage]

In fact what we can definitely do is detect the version if there is only one installed and list the existing versions in the error message if there are more than one

[gavinking]

Yes, much better!

For M2, hopefully. :-)

[FroMage]

Looks like M4 :(

[alesj]

Version ranges bring a bunch of problems; it's a NP problem. ;-)
I'll see what can be done, but definitely not M3, hopefully M4 ...

Version ranges bring a bunch of problems

I agree. Personally I don't even see this as being on the roadmap for Ceylon 1.0.

[alesj]

For example; OSGi only recently properly addressed this issue - resolver is now part of the spec; after 10y+.
(of course it was already done before, but in a 1M diff ways)

[FroMage]

M6.
