API

• semverUtils.parse(semverString)
• semverUtils.stringify(semverObject)
• semverUtils.parseRange(rangeString)
• semverUtils.stringifyRange(rangeArray)

semverUtils.parse(semverString)

Turns a string such as 1.0.6-1+build-623 into the object

{ semver:   '1.0.6-1+build-623'
, version:  '1.0.6'
, major:    '1'
, minor:    '0'
, patch:    '6'
, release:  '1'
, build:    'build-623'
}

returns null on error

semverUtils.stringify(semverObject)

Creates a string such as 1.0.6-1+build-623 from the object

{ major:    '1'
, minor:    '0'
, patch:    '6'
, release:  '1'
, build:    'build-623'
}

semverUtils.parseRange(rangeString)

A solution to https://github.com/isaacs/node-semver/issues/10

Parses a range string into an array of semver objects

>= 1.1.7 < 2.0.0 || 1.1.3 becomes

[
    {
        "semver": ">= v1.1.7"
      , "operator": ">="
      , "major": 1
      , "minor": 1
      , "patch": 7
    }
  , {
        "semver": "< v2.0.0"
      , "operator": "<"
      , "major": 2
      , "minor": 0
      , "patch": 0
    }
  , {
        "operator": "||"
    }
  , {
        "semver": "v1.1.3"
      , "operator": "="
      , "major": 1
      , "minor": 1
      , "patch": 3
    }

]

semverUtils.stringifyRange(rangeArray)

Creates a range string such as >= 1.1.7 < 2.0.0 || 1.1.3 from an array of semver objects (and operators) such as

[
    { "semver": ">= v1.1.7"
    , "operator": ">="
    , "major": 1
    , "minor": 1
    , "patch": 7
    }
  , { "semver": "< v2.0.0"
    , "operator": "<"
    , "major": 2
    , "minor": 0
    , "patch": 0
    }
  , { "operator": "||"
    }
  , { "semver": "v1.1.3"
