changelog-parser 0.0.8

Parses changelog files

changelog-parser

Yet another python changelog parser.

• Loads data from a CHANGELOG.md file using code like:

  import changelog
  
  with open( "CHANGELOG.md", 'rb' ) as fp:
    changes = changelog.load( fp )
  

  or

  import changelog
  
  with open( "CHANGELOG.md", 'r' ) as fp:
    changes = changelog.loads( fp.read() )
  

• Returns it in the following schema (some types are Python objects and not valid JSON schema):

  {
    "$schema": "https://json-schema.org/draft-07/schema#",
    "title": "Loaded Changelog",
    "type": "array",
    "items": {
      "type": "object",
      "properties": {
        "version": {
          "oneOf": [ {
            "const": "Unreleased"
          }, {
            "type": "semver.Version",
            "description": "Python object from https://pypi.org/project/semver/"
          } ]
        },
        "date": {
          "oneOf": [ {
            "const": null
          }, {
            "type": "datetime.date",
            "description": "Python object from https://docs.python.org/3/library/datetime.html#date-objects; parsed using \"fromisoformat\""
          } ]
        },
        "yanked": {
          "type": "boolean"
        },
        "added": { "$ref": "#/$defs/change_list" },
        "changed": { "$ref": "#/$defs/change_list" },
        "depreciated": { "$ref": "#/$defs/change_list" },
        "removed": { "$ref": "#/$defs/change_list" },
        "fixed": { "$ref": "#/$defs/change_list" },
        "security": { "$ref": "#/$defs/change_list" },
        "compare_url": {
          "type": "string",
          "pattern": "^https?:\\/\\/.+"
        }
      },
      "required": [ "version", "date", "yanked" ],
      "additionalProperties": false
    },
    "$defs": {
      "change_list": {
        "type": "array",
        "items": { "type": "string" }
      }
    }
  }
  

• Dumps data, structured like that above, to a CHANGELOG.md file using code like

  import changelog
  import semver
  from datetime import date
  
  with open( "CHANGELOG.md", 'rb' ) as fp:
    changes = changelog.load( fp )
  
  changes.insert( 0, {
     "version": semver.Version( major = 0, minor = 0, patch = 6 ),
     "date": date.today(),
     "added": [ "`dump` and `dumps` examples" ]
  } )
  
  with open( "CHANGELOG.md", 'wb' ) as fp:
    changelog.dump( changes, fp )
  

  or

  import changelog
  ...
  changelog_contents = changelog.dumps( changes )
  with open( "CHANGELOG.md", 'w' ) as fp:
    fp.write( changelog_contents )
