Natural Number.
Natural Number. The
ExperimentalVersion
allows for experimentation with changes to TASTy without committing to any guarantees of compatibility.A zero value indicates that the TASTy version is from a stable, final release.
A strictly positive value indicates that the TASTy version is experimental. An experimental TASTy file can only be read by a tool with the same version. However, tooling with an experimental TASTy version is able to read final TASTy documents if the file's
MinorVersion
is strictly less than the current value. - final val FALSEconst: Int(3)

Natural number.
Natural number. Each increment of the

- final val MinorVersion: Int
Natural number.
Natural number. Each increment of the

, within a series declared by theMajorVersion

This method implements a binary relation (
<:<
) between two TASTy versions.This method implements a binary relation (
<:<
) between two TASTy versions.We label the lhs
file
and rhscompiler
. iffile <:< compiler
then the TASTy file is valid to be read.A TASTy version, e.g.
v := 28.0-3
is composed of three fields:- v.major == 28
- v.minor == 0
- v.experimental == 3
TASTy versions have a partial order, for example,
a <:< b
andb <:< a
are both false ifa
andb
have differentmajor
fields.a
andb
have the samemajor
&minor
fields, but differentexperimental
fields, both non-zero.
A TASTy version with a zero value for its
experimental
field is considered to be stable. Files with a stable TASTy version can be read by a compiler with an unstable TASTy version, (where the compiler's TASTy version has a higherminor
field).A compiler with a stable TASTy version can never read a file with an unstable TASTy version.
We follow the given algorithm:
compilerMinor
,(fileMajor, fileMinor, fileExperimental) match case (
compilerMajor,
compilerExperimental) => true // full equality case (
compilerMajor, minor, 0) if minor < compilerMinor => true // stable backwards compatibility case _ => false

Should be kept in sync with NameTags. Converts constants to a String representing their identifier, or NotANameTag(tag) if unrecognised.
