v0.2.0

v0.2.0 (2025-07-07)

We have made significant refactoring of the codebase to optimize readability, make naming more intuitive, and added new features.

There are a large number of API changes, please check the code to understand the migration.

Added

• DocBuilder::when_group_flat (equivalent to nil.flat_alt(self)) and DocBuilder::when_group_break (equivalent to self.flat_alt(nil))
• DocAllocator::spaces (create a document of n spaces)
• DocBuilder::repeat (repeat self n times)
• Doc::PartialUnion variant and DocBuilder::partial_union (like union but only tries fitting on the first line)
• Doc::Flatten variant and DocBuilder::flatten (force the document to always render flat)
• Arena::len and Arena::is_empty

Changed

• Bump Rust edition to 2021
• Upgrade unicode-width to 0.2
• Rename some variants of Doc for clarity (breaking change)
• Rename the printing function Doc::pretty → Doc::print to avoid ambiguity (breaking change)
• Make Debug output for Doc more compact and fix matching of SoftLine

Removed

• Removed Affixes
• Drop Doc:Annotated and termcolor features (breaking change)
