Docs 2.2.0

2.1.0 - リミッター解除 - Removes Type Restriction

This release focuses on removing the type restriction we previously had when finding values. This is a huge quality of life improvement for the users since you will be able to get whatever you want. With great power comes... some caveats, obviously casting objects won't work and slicing them will turn them into strings. So there are features that won't work with objects and arrays. However those that work nicely like if statements have gotten updated documentation.


  • Removes type restriction when finding values with mapping.path
  • Slicing now works with arrays


  • Adds lots of test + ensures that we do not loose precicion on decimal casting.
  • Contribution Doc updates, poetry settings commands are now correct and contribution is easier to follow
  • Github actions run on push only to master
  • Github actions run on pull requests to master even from forks
  • Pre commit action for 'test files must end in _test' removed. We prefix our test files with test_

Docs 2.1.0

ps: The japanese just means Limiter Release, and is sometimes used in anime fighting scenes, I thought it was fitting.

2.0.0 - Iterables

This release introduces a breaking change where path_to_iterable is renamed to iterables. iterables is also now a list of iterable objects that contain an alias and a path. This lets you iterate over multiple lists recursively from 1 object.

  • Feature: Adds recursive multiple iteration with iterables
  • Breaking: Removes path_to_iterable
  • Updates docs/
  • Updates docs/
  • Fix: Points links in docs to read the docs

Docs 1.2.0

1.1.0 - IN condition support in if statements

This minor release adds support for in condition for if_statements. This lets you check if the value you found is in some list of values or part of a string.

1.0.2 - Bugfix

Loading schema.json used relatve path that did not work when package was imported by other package. Now we use '{0}/schema.json'.format(os.path.dirname(__file__)) to get absolute path to our schema.json.


  • adds python versions badge
  • removes bad part of documentation

  • Combine multiple values to one.
  • Default values
  • If statements
    • is, contains, not
  • casting
