Version prediction Issue

[Vishnu-2810]

I'm trying to add a custom checker for Image Magick by the version patterns are ImageMagick-([\d]+.[\d]+.[\d]+-[\d]+)
(ImageMagick-7.1.1-15) but after adding the checker class I'm getting the version as 7.1.1.15 why how -15 is changed to .15

The version is inconsistent in such ways ..How to resolve this issue @Error838 ?

Thanks In Advance

We currently change all delimeters to . internally to handle some hoary version representation cases (versions are the worst).

If you're just trying to practice making checkers, just tell it that it should be 7.1.1.15 for now and move on with life.

I'm not adverse to improving the way we handle delimiters, but that's a huge project that'll need to be run against a lot of data and it's not happening fast. Arbitrary version compare is just surprisingly hard in practice and we'd have to know a lot about "does - mean after? What about ~? Does it sometimes mean before?"

Component versions are a mess but if more components aligned with Semantic Versioning life would be easier. As @terriko remarked, it is a very difficult task - perhaps the greatest contribution would be to encourage maintainers to adopt semantic versioning as this COULD have a significant improvement in improving vulnerability management across the industry.
