Support for semantic version strings and comparison

[codewithcheese]

Hi CUEbies

Do you know of any implementations for semantic version and comparison in-built or CUE? I see there is an issue from a year ago here: #407

I am about to implement a CUE based solution for semantic version strings and comparison but double checking before coding.

I'm planning a CUE based solution, use regexp to parse a version string into its components something like { major: number, minor: number, patch: number, extension:string } then implement a comparison function; a long list of conditionals which probably wont be pretty but get the job done.

We use semantic version strings in our config files to represent versions and also have a need for version comparison to check that component updates are mutually compatible.

Apologies for the delay in replying, @codewithcheese. A regexp approach will work (per #407 (comment)). And per @mpvl the plan at the moment is not necessarily to provide a builtin equivalent of https://pkg.go.dev/golang.org/x/mod/semver, rather to consider what building blocks would be better primitive (@mpvl gives the example of https://pkg.go.dev/golang.org/x/text/collate
