|
* change the version based on a basic expression
|
|
*
|
|
* Expressions have two pieces, the version piece to
|
|
* set and the new value. If the version peice is not
|
|
* "tag" then the new value can be left of and the preivous
|
|
* value will simply be incremented by one. if the version
|
|
* peice is tag, some special rules apply:
|
|
* 1. leaving the value empty will remove a tag
|
|
* 2. adding a new tag bumps the minor version
|
|
*
|
|
* examples:
|
|
*
|
|
* expr: minor
|
|
* 1.4.1 => 1.5.0
|
|
*
|
|
* expr: minor=10
|
|
* 1.5.5 => 1.10.0
|
|
*
|
|
* expr: major=4
|
|
* 0.0.1 => 4.0.0
|
|
*
|
|
* expr: tag=beta2
|
|
* 4.0.0-beta1 => 4.0.0-beta2
|
|
*
|
|
* expr: tag=snapshot
|
|
* 4.0.0 => 4.1.0-snapshot
|
|
*
|
|
* expr: tag=
|
|
* 4.0.0-rc1 => 4.0.0
