Compiler Versioning

Rules

The quark compiler requires a version declaration of the form quark x.y.z; or quark x.y; or quark *;. In the absence of a quark version declaration, the compiler emits a warning but proceeds as if quark *; were specified. Major version zero is treated the same as non-zero major versions.

Given source code declared quark x.y.z;

• the compiler must be version x.a where a > y, or
• the compiler must be version x.y.b where b >= z. Otherwise there is a version mismatch.

There is a compiler command line option --version-warning that causes the compiler to

• emit a warning that said option is enabled, and to
• display version-related errors but then proceed as if quark *; were specified.

Pegging quark version

To allow CI/CD use of quark the quark install script allows version pegging. With this it's possible to to ensure that quark code and compiler are compatible.
