# 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.
|
||||
```
|
||||
|
||||
```
|
||||
$ voc ../src/SemVer.Mod -s SemVerExample.Mod -m 2>/dev/null && ./SemVerExample
|
||||
../src/SemVer.Mod Compiling SemVer. New symbol file. 5302 chars.
|
||||
SemVerExample.Mod Compiling SemVerExample. Main program. 1204 chars.
|
||||
major=1; minor=2; patch=3; preRelease=alpha.1; build=build.5;
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Building
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
## Tests
|
||||
|
||||
```
|
||||
make test
|
||||
```
|
||||
|
||||
Includes various valid and invalid test cases to confirm compliance with
|
||||
the SemVer 2.0.0 specification.
|
||||
|
||||
## Dependencies
|
||||
|
||||
- For Building: `voc` (duh!)
|
||||
- Test runner: none
|
||||
|
||||
## TODO
|
||||
|
||||
- Compare
|
||||
- Equals
|
||||
- ToString
|
||||
- ParseConstraint
|
||||
- MatchConstraint
|
||||
- IsStable
|
||||
- IsPreRelease
