# Semantic Versioning for Vishap Oberon Compiler (voc)

A strict, specification-compliant Semantic Versioning parser for [Vishap Oberon](https://vishap.oberon.am).
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
    Out.String("Invalid version string."); Out.Ln;
  END;
END SemVerExample.
```

```
