Changelog

Unreleased

0.4.2 - Jan 22 2024

Bug fixes

• fixed a bug that caused RopeSlice::line_slice() to panic or halt forever when both the start and end of the range are equal to RopeSlice::line_len() and the RopeSlice didn't end with a line break (#16);

0.4.1 - Dec 1 2023

Bug fixes

• fixed a typo that caused "r" to be stripped instead of the carriage return character ("\r") when truncating trailing line breaks;

0.4.0 - Oct 11 2023

Additions

• added a few new methods to Rope and RopeSlice that allow converting between UTF-16 and byte offsets by tracking the number of UTF-16 code units stored in those objects. It is important to note that these APIs come with a performance cost. As a result, these methods are only accessible by enabling a new feature flag called utf16-metric, which is disabled by default;

Performance

• the performance of Rope::replace was improved by another 10-15%;

0.3.0 - Apr 16 2023

Changes

• both the line_of_byte() and byte_of_line() methods on Ropes and RopeSlices now interpret their argument as byte and line offsets, respectively. This allows those methods to accept the full byte length or line length of the Rope/RopeSlice as a valid argument without panicking;

Bug fixes

• fixed a very rare bug where the Lines iterator would include the trailing '\r' if a line was terminated by a CRLF which was split across consecutive chunks;

Performance

• the byte_slice() method on Ropes and RopeSlices is around 10% faster;

0.2.0 - Mar 26 2023

Performance

• the leaves of the B-tree are now gap buffers instead of simple Strings, which improves the performance of consecutive edits applied to the same cursor position. This alone resulted in a 8-15% improvement in the crdt-benchmarks, and together with other tweaks it makes v0.2 80-90% faster than v0.1 on those editing traces;

• RopeBuilder::append() is around 20% faster;

Breaking changes

• the Chunks iterator no longer implements ExactSizeIterator;
