# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Added

### Changed

### Removed

## [0.5.0] - 2026-07-25

### Changed

- `Mpl` plot initialization shortcuts now properly route through
  `Mpl::with_init`
- Relicense to Apache-2.0

### Added

- New `CloseFig` plotting command for better behavior with other
  (re)initialization commands

## [0.4.0] - 2026-07-24

### Changed

- Prelude items are now placed after imports but before plot initialization,
  rather than after initialization alongside non-prelude commands.
- `RcParam` is now a prelude item.

## [0.3.0] - 2026-06-25

### Added

- `AsPy` implementations for tuples (1- through 12-tuples) and `Option<T>`.
- `From<Option<T>>` implementation for `PyValue`.
- Builder methods on `Mpl` for customizing the Python executable
  (`with_python`/`set_python`, `with_python_args`/`set_python_args`), import
  block (`with_imports`/`set_imports`), and initialization block
  (`with_init`/`set_init`).
- `concat_with` method on `Mpl` as a by-reference alternative to `concat`.
- New plotting commands.

### Changed

- Renamed public constant `PRELUDE` to `IMPORTS`.
- `AsPy` for `f64` now correctly handles NaN and infinity values.
- `AsPy` for `&str`/`String` now properly escapes special characters.
- `concat` now takes `self` and `other` by value instead of by reference.
- Import and initialization code is now stored on `Mpl` directly rather than
  being managed through `DefPrelude`/`DefInit` command objects. The default
  matplotlib backend (`QtAgg`) is no longer forced; use the `Backend` command
  to choose one explicitly.
- File paths in generated Python scripts are now properly escaped.
- The Python executable used by `Mpl::run` is now configurable (defaults to
  `python3`).

### Removed

- `PyValue::Var` variant.

## [0.2.0] - 2024-10-25

### Added

- New object interface to the initialization procedures previously only
  accessible as constructor methods of `Mpl`. Namely, the methods `new_3d`,
  `new_grid`, and `new_gridspec` now have associated "command types" `Init3D`,
  `InitGrid`, and `InitGridSpec`. This is to solve the problem of being able to
  combine styling (e.g. `rcParam` settings) with more complicated figures. These
  constructor methods now use the new types internally, and additional
  constructors `new_3d_with`, `new_grid_with`, and `new_gridspec_with` have also
  been added as another way to solve this problem.

### Changed

- Dumb code style changes regarding line breaks around assignment operators.

## [0.1.1] - 2024-10-21

### Changed

- Replaced incorrect references in README code examples to `mpl` as a crate
  name; the name is actually `matplotlib`.
- Instead of dumbly recording all prelude and non-prelude commands in the same
  vector in `Mpl`, separate them out so that the command list doesn't have to be
  re-sorted all the time.

## [0.1.0] - 2024-08-01

### Added

- First working release
