Semantic Versioning for Vishap Oberon Compiler (voc)

A strict, specification-compliant Semantic Versioning parser for Vishap Oberon. Designed for use in package managers, version comparison tools, and system-level Oberon utilities.

Features

Parses full SemVer 2.0.0 strings (MAJOR.MINOR.PATCH[-PRERELEASE][+BUILD])
Validates all pre-release and build metadata
Outputs parsed results into a structured Version record

Example

Input:

1.1.2-prerelease+meta

Result (parsed record):

major=1;
minor=1;
patch=2;
preRelease=prerelease;
build=meta;

Usage

MODULE SemVerExample;
  IMPORT SemVer, Out;
VAR
  v: SemVer.Version;
  ok: BOOLEAN;
BEGIN
  SemVer.Parse("1.2.3-alpha.1+build.5", v, ok);
  IF ok THEN
    Out.String("major="); Out.Int(v.Major, 1); Out.String("; ");
    Out.String("minor="); Out.Int(v.Minor, 1); Out.String("; ");
    Out.String("patch="); Out.Int(v.Patch, 1); Out.String("; ");
    Out.String("preRelease="); Out.String(v.PreRelease); Out.String("; ");
    Out.String("build="); Out.String(v.Build); Out.String(";");
    Out.Ln;
  ELSE

  END;
END SemVerExample.
