Instance Method Details

Given a concrete version, this returns a ~ constraint (when possible) that should be used, for example, in composer.json.

For example:

* 1.2.1         -> ~1.2
* 1.2           -> ~1.2
* v3.2.1        -> ~3.2
* 2.0-beta.1    -> ~2.0@beta
* dev-master    -> ~2.1@dev      (dev version with alias)
* dev-master    -> dev-master    (dev versions are untouched)
