jc - JSON Convert Version string output parser

Best-effort attempt to parse various styles of version numbers. This parser is based off of the version parser included in the CPython distutils library.

If the version string conforms to some de facto-standard versioning rules followed by many developers a strict key will be present in the output with a value of true along with the named parsed components.

All other version strings will have a strict value of false and a components key will contain a list of detected parts of the version string.

See Also: semver parser.

Usage (cli):

$ echo 1.2a1 | jc --ver

Usage (module):

import jc
result = jc.parse('ver', version_string_output)

Schema:

{
  "major":                  integer,
  "minor":                  integer,
  "patch":                  integer,
  "prerelease":             string,
  "prerelease_num":         integer,
  "components": [
                            integer/string
  ],
  "strict":                 boolean
}

Examples:

$ echo 1.2a1 | jc --ver -p
{
  "major": 1,
  "minor": 2,
  "patch": 0,
  "prerelease": "a",
  "prerelease_num": 1,
  "strict": true
}

$ echo 1.2a1 | jc --ver -p -r
{
  "major": "1",
  "minor": "2",
  "patch": "0",
  "prerelease": "a",
  "prerelease_num": "1",
  "strict": true
}

$ echo 1.2beta3 | jc --ver -p
{
  "components": [
    1,
    2,
    "beta",
    3
  ],
  "strict": false
}

$ echo 1.2beta3 | jc --ver -p -r
{
  "components": [
    "1",
    "2",
    "beta",
    "3"
  ],
  "strict": false
}
