The minimum +supported version of Rust is now documented to be 1.56. + +* [#526](https://github.com/mgeisler/textwrap/pull/526): Ignore ANSI hyperlinks + in `display_width`: calculations. +* [#521](https://github.com/mgeisler/textwrap/pull/521): Add `Options::width` + setter method. +* [#520](https://github.com/mgeisler/textwrap/pull/520): Clarify that + `WordSeparator` is an enum rather than a trait. +* [#518](https://github.com/mgeisler/textwrap/pull/518): Test with latest stable + and nightly Rust, but check that we can build with Rust 1.56. + +## Version 0.16.0 (2022-10-23) + +This release marks `Options` as `non_exhaustive` and extends it to +make line endings configurable, it adds new fast paths to `fill` and +`wrap`, and it fixes crashes in `unfill` and `refill`. + +* [#480](https://github.com/mgeisler/textwrap/pull/480): Mark + `Options` as `non_exhaustive`. This will allow us to extend the + struct in the future without breaking backwards compatibility. +* [#478](https://github.com/mgeisler/textwrap/pull/478): Add fast + paths to `fill` and `wrap`. This makes the functions 10-25 times + faster when the no wrapping is needed. +* [#468](https://github.com/mgeisler/textwrap/pull/468): Fix `refill` + to add back correct line ending. +* [#467](https://github.com/mgeisler/textwrap/pull/467): Fix crashes + in `unfill` and `refill`. +* [#458](https://github.com/mgeisler/textwrap/pull/458): Test with + Rust 1.56 (first compiler release with support for Rust 2021). +* [#454](https://github.com/mgeisler/textwrap/pull/454): Make line + endings configurable. +* [#448](https://github.com/mgeisler/textwrap/pull/448): Migrate to + the Rust 2021 edition. + +## Version 0.15.2 (2022-10-24) + +This release is identical to 0.15.0 and is only there to give people a +way to install crates which depend on the yanked 0.15.1 release. See +[#484](https://github.com/mgeisler/textwrap/issues/484) for details. + +## Version 0.15.1 (2022-09-15) + +This release was yanked since it accidentally broke backwards +compatibility with 0.15.0. + +## Version 0.15.0 (2022-02-27) + +This is a major feature release with two main changes: + +* [#421](https://github.com/mgeisler/textwrap/pull/421): Use `f64` + instead of `usize` for fragment widths. + + This fixes problems with overflows in the internal computations of + `wrap_optimal_fit` when fragments (words) or line lengths had + extreme values, such as `usize::MAX`. + +* [#438](https://github.com/mgeisler/textwrap/pull/438): Simplify + `Options` by removing generic type parameters. + + This change removes the new generic parameters introduced in version + 0.14, as well as the original `WrapSplitter` parameter which has + been present since very early versions. + + The result is a simplification of function and struct signatures + across the board. So what used to be + + ```rust + let options: Options< + wrap_algorithms::FirstFit, + word_separators::AsciiSpace, + word_splitters::HyphenSplitter, + > = Options::new(80); + ``` + + if types are fully written out, is now simply + + ```rust + let options: Options<'_> = Options::new(80); + ``` + + The anonymous lifetime represent the lifetime of the + `initial_indent` and `subsequent_indent` strings. The change is + nearly performance neutral (a 1-2% regression). + +Smaller improvements and changes: + +* [#404](https://github.com/mgeisler/textwrap/pull/404): Make + documentation for short last-line penalty more precise. +* [#405](https://github.com/mgeisler/textwrap/pull/405): Cleanup and + simplify `Options` docstring. +* [#411](https://github.com/mgeisler/textwrap/pull/411): Default to + `OptimalFit` in interactive example. +* [#415](https://github.com/mgeisler/textwrap/pull/415): Add demo + program to help compute binary sizes. +* [#423](https://github.com/mgeisler/textwrap/pull/423): Add fuzz + tests with fully arbitrary fragments. +* [#424](https://github.com/mgeisler/textwrap/pull/424): Change + `wrap_optimal_fit` penalties to non-negative numbers. +* [#430](https://github.com/mgeisler/textwrap/pull/430): Add + `debug-words` example. +* [#432](https://github.com/mgeisler/textwrap/pull/432): Use precise + dependency versions in Cargo.toml. + +## Version 0.14.2 (2021-06-27) + +The 0.14.1 release included more changes than intended and has been +yanked. The change intended for 0.14.1 is now included in 0.14.2. + +## Version 0.14.1 (2021-06-26) + +This release fixes a panic reported by @Makoto, thanks! + +* [#391](https://github.com/mgeisler/textwrap/pull/391): Fix panic in + `find_words` due to string access outside of a character boundary. + +## Version 0.14.0 (2021-06-05) + +This is a major feature release which makes Textwrap more configurable +and flexible. The high-level API of `textwrap::wrap` and +`textwrap::fill` remains unchanged, but low-level structs have moved +around. + +The biggest change is the introduction of new generic type parameters +to the `Options` struct. These parameters lets you statically +configure the wrapping algorithm, the word separator, and the word +splitter. If you previously spelled out the full type for `Options`, +you now need to take the extra type parameters into account. This +means that + +```rust +let options: Options<HyphenSplitter> = Options::new(80); +``` + +changes to + +```rust +let options: Options< + wrap_algorithms::FirstFit, + word_separators::AsciiSpace, + word_splitters::HyphenSplitter, +> = Options::new(80); +``` + +This is quite a mouthful, so we suggest using type inference where +possible. You won’t see any chance if you call `wrap` directly with a +width or with an `Options` value constructed on the fly. Please open +an issue if this causes problems for you! + +### New `WordSeparator` Trait + +* [#332](https://github.com/mgeisler/textwrap/pull/332): Add + `WordSeparator` trait to allow customizing how words are found in a + line of text. Until now, Textwrap would always assume that words are + separated by ASCII space characters. You can now customize this as + needed. + +* [#313](https://github.com/mgeisler/textwrap/pull/313): Add support + for using the Unicode line breaking algorithm to find words. This is + done by adding a second implementation of the new `WordSeparator` + trait. The implementation uses the unicode-linebreak crate, which is + a new optional dependency. + + With this, Textwrap can be used with East-Asian languages such as + Chinese or Japanese where there are no spaces between words. + Breaking a long sequence of emojis is another example where line + breaks might be wanted even if there are no whitespace to be found. + Feedback would be appreciated for this feature. + + +### Indent + +* [#353](https://github.com/mgeisler/textwrap/pull/353): Trim trailing + whitespace from `prefix` in `indent`. + + Before, empty lines would get no prefix added. Now, empty lines have + a trimmed prefix added. This little trick makes `indent` much more + useful since you can now safely indent with `"# "` without creating + trailing whitespace in the output due to the trailing whitespace in + your prefix. + +* [#354](https://github.com/mgeisler/textwrap/pull/354): Make `indent` + about 20% faster by preallocating the output string. + + +### Documentation + +* [#308](https://github.com/mgeisler/textwrap/pull/308): Document + handling of leading and trailing whitespace when wrapping text. + +### WebAssembly Demo + +* [#310](https://github.com/mgeisler/textwrap/pull/310): Thanks to + WebAssembly, you can now try out Textwrap directly in your browser. + Please try it out: https://mgeisler.github.io/textwrap/. + +### New Generic Parameters + +* [#331](https://github.com/mgeisler/textwrap/pull/331): Remove outer + boxing from `Options`. + +* [#357](https://github.com/mgeisler/textwrap/pull/357): Replace + `core::WrapAlgorithm` enum with a `wrap_algorithms::WrapAlgorithm` + trait. This allows for arbitrary wrapping algorithms to be plugged + into the library. + +* [#358](https://github.com/mgeisler/textwrap/pull/358): Switch + wrapping functions to use a slice for `line_widths`. + +* [#368](https://github.com/mgeisler/textwrap/pull/368): Move + `WordSeparator` and `WordSplitter` traits to separate modules. + Before, Textwrap had several top-level structs such as + `NoHyphenation` and `HyphenSplitter`. These implementations of + `WordSplitter` now lives in a dedicated `word_splitters` module. + Similarly, we have a new `word_separators` module for + implementations of `WordSeparator`. + +* [#369](https://github.com/mgeisler/textwrap/pull/369): Rename + `Options::splitter` to `Options::word_splitter` for consistency with + the other fields backed by traits. + +## Version 0.13.4 (2021-02-23) + +This release removes `println!` statements which was left behind in +`unfill` by mistake. + +* [#296](https://github.com/mgeisler/textwrap/pull/296): Improve house + building example with more comments. +* [#297](https://github.com/mgeisler/textwrap/pull/297): Remove debug + prints in the new `unfill` function. + +## Version 0.13.3 (2021-02-20) + +This release contains a bugfix for `indent` and improved handling of +emojis. We’ve also added a new function for formatting text in columns +and functions for reformatting already wrapped text. + +* [#276](https://github.com/mgeisler/textwrap/pull/276): Extend + `core::display_width` to handle emojis when the unicode-width Cargo + feature is disabled. +* [#279](https://github.com/mgeisler/textwrap/pull/279): Make `indent` + preserve existing newlines in the input string. Before, + `indent("foo", "")` would return `"foo\n"` by mistake. It now + returns `"foo"` instead. +* [#281](https://github.com/mgeisler/textwrap/pull/281): Ensure all + `Options` fields have examples. +* [#282](https://github.com/mgeisler/textwrap/pull/282): Add a + `wrap_columns` function. +* [#294](https://github.com/mgeisler/textwrap/pull/294): Add new + `unfill` and `refill` functions. + +## Version 0.13.2 (2020-12-30) + +This release primarily makes all dependencies optional. This makes it +possible to slim down textwrap as needed. + +* [#254](https://github.com/mgeisler/textwrap/pull/254): `impl + WordSplitter` for `Box<T> where T: WordSplitter`. +* [#255](https://github.com/mgeisler/textwrap/pull/255): Use command + line arguments as initial text in interactive example. +* [#256](https://github.com/mgeisler/textwrap/pull/256): Introduce + fuzz tests for `wrap_optimal_fit` and `wrap_first_fit`. +* [#260](https://github.com/mgeisler/textwrap/pull/260): Make the + unicode-width dependency optional. +* [#261](https://github.com/mgeisler/textwrap/pull/261): Make the + smawk dependency optional. + +## Version 0.13.1 (2020-12-10) + +This is a bugfix release which fixes a regression in 0.13.0. The bug +meant that colored text was wrapped incorrectly. + +* [#245](https://github.com/mgeisler/textwrap/pull/245): Support + deleting a word with Ctrl-Backspace in the interactive demo. +* [#246](https://github.com/mgeisler/textwrap/pull/246): Show build + type (debug/release) in interactive demo. +* [#249](https://github.com/mgeisler/textwrap/pull/249): Correctly + compute width while skipping over ANSI escape sequences. + +## Version 0.13.0 (2020-12-05) + +This is a major release which rewrites the core logic, adds many new +features, and fixes a couple of bugs. Most programs which use +`textwrap` stays the same, incompatibilities and upgrade notes are +given below. + +Clone the repository and run the following to explore the new features +in an interactive demo (Linux only): + +```sh +$ cargo run --example interactive --all-features +``` + +### Bug Fixes + +#### Rewritten core wrapping algorithm + +* [#221](https://github.com/mgeisler/textwrap/pull/221): Reformulate + wrapping in terms of words with whitespace and penalties. + +The core wrapping algorithm has been completely rewritten. This fixed +bugs and simplified the code, while also making it possible to use +`textwrap` outside the context of the terminal. + +As part of this, trailing whitespace is now discarded consistently +from wrapped lines. Before we would inconsistently remove whitespace +at the end of wrapped lines, except for the last. Leading whitespace +is still preserved. + +### New Features + +#### Optimal-fit wrapping + +* [#234](https://github.com/mgeisler/textwrap/pull/234): Introduce + wrapping using an optimal-fit algorithm. + +This release adds support for new wrapping algorithm which finds a +globally optimal set of line breaks, taking certain penalties into +account. As an example, the old algorithm would produce + + "To be, or" + "not to be:" + "that is" + "the" + "question" + +Notice how the fourth line with “the” is very short. The new algorithm +shortens the previous lines slightly to produce fewer short lines: + + "To be," + "or not to" + "be: that" + "is the" + "question" + +Use the new `textwrap::core::WrapAlgorithm` enum to select between the +new and old algorithm. By default, the new algorithm is used. + +The optimal-fit algorithm is inspired by the line breaking algorithm +used in TeX, described in the 1981 article [_Breaking Paragraphs into +Lines_](http://www.eprg.org/G53DOC/pdfs/knuth-plass-breaking.pdf) by +Knuth and Plass. + +#### In-place wrapping + +* [#226](https://github.com/mgeisler/textwrap/pull/226): Add a + `fill_inplace` function. + +When the text you want to fill is already a temporary `String`, you +can now mutate it in-place with `fill_inplace`: + +```rust +let mut greeting = format!("Greetings {}, welcome to the game! You have {} lives left.", + player.name, player.lives); +fill_inplace(&mut greeting, line_width); +``` + +This is faster than calling `fill` and it will reuse the memory +already allocated for the string. + +### Changed Features + +#### `Wrapper` is replaced with `Options` + +* [#213](https://github.com/mgeisler/textwrap/pull/213): Simplify API + with only top-level functions. +* [#215](https://github.com/mgeisler/textwrap/pull/215): Reintroducing + the type parameter on `Options` (previously known as `Wrapper`). +* [#219](https://github.com/mgeisler/textwrap/pull/219): Allow using + trait objects with `fill` & `wrap`. +* [#227](https://github.com/mgeisler/textwrap/pull/227): Replace + `WrapOptions` with `Into<Options>`. + +The `Wrapper` struct held the options (line width, indentation, etc) +for wrapping text. It was also the entry point for actually wrapping +the text via its methods such as `wrap`, `wrap_iter`, +`into_wrap_iter`, and `fill` methods. + +The struct has been replaced by a simpler `Options` struct which only +holds options. The `Wrapper` methods are gone, their job has been +taken over by the top-level `wrap` and `fill` functions. The signature +of these functions have changed from + +```rust +fn fill(s: &str, width: usize) -> String; + +fn wrap(s: &str, width: usize) -> Vec<Cow<'_, str>>; +``` + +to the more general + +```rust +fn fill<'a, S, Opt>(text: &str, options: Opt) -> String +where + S: WordSplitter, + Opt: Into<Options<'a, S>>; + +fn wrap<'a, S, Opt>(text: &str, options: Opt) -> Vec<Cow<'_, str>> +where + S: WordSplitter, + Opt: Into<Options<'a, S>>; +``` + +The `Into<Options<'a, S>` bound allows you to pass an `usize` (which +is interpreted as the line width) *and* a full `Options` object. This +allows the new functions to work like the old, plus you can now fully +customize the behavior of the wrapping via `Options` when needed. + +Code that call `textwrap::wrap` or `textwrap::fill` can remain +unchanged. Code that calls into `Wrapper::wrap` or `Wrapper::fill` +will need to be update. This is a mechanical change, please see +[#213](https://github.com/mgeisler/textwrap/pull/213) for examples. + +Thanks to @CryptJar and @Koxiat for their support in the PRs above! + +### Removed Features + +* The `wrap_iter` and `into_wrap_iter` methods are gone. This means + that lazy iteration is no longer supported: you always get all + wrapped lines back as a `Vec`. This was done to simplify the code + and to support the optimal-fit algorithm. + + The first-fit algorithm could still be implemented in an incremental + fashion. Please let us know if this is important to you. + +### Other Changes + +* [#206](https://github.com/mgeisler/textwrap/pull/206): Change + `Wrapper.splitter` from `T: WordSplitter` to `Box<dyn + WordSplitter>`. +* [#216](https://github.com/mgeisler/textwrap/pull/216): Forbid the + use of unsafe code. + +## Version 0.12.1 (2020-07-03) + +This is a bugfix release. + +* Fixed [#176][issue-176]: Mention compile-time wrapping by linking to + the [`textwrap-macros` crate]. +* Fixed [#193][issue-193]: Wrapping with `break_words(false)` was + broken and would cause extra whitespace to be inserted when words + were longer than the line width. + +## Version 0.12.0 (2020-06-26) + +The code has been updated to the [Rust 2018 edition][rust-2018] and +each new release of `textwrap` will only support the latest stable +version of Rust. Trying to support older Rust versions is a fool's +errand: our dependencies keep releasing new patch versions that +require newer and newer versions of Rust. + +The `term_size` feature has been replaced by `terminal_size`. The API +is unchanged, it is just the name of the Cargo feature that changed. + +The `hyphenation` feature now only embeds the hyphenation patterns for +US-English. This slims down the dependency. + +* Fixed [#140][issue-140]: Ignore ANSI escape sequences. +* Fixed [#158][issue-158]: Unintended wrapping when using external splitter. +* Fixed [#177][issue-177]: Update examples to the 2018 edition. + +## Version 0.11.0 (2018-12-09) + +Due to our dependencies bumping their minimum supported version of +Rust, the minimum version of Rust we test against is now 1.22.0. + +* Merged [#141][issue-141]: Fix `dedent` handling of empty lines and + trailing newlines. Thanks @bbqsrc! +* Fixed [#151][issue-151]: Release of version with hyphenation 0.7. + +## Version 0.10.0 (2018-04-28) + +Due to our dependencies bumping their minimum supported version of +Rust, the minimum version of Rust we test against is now 1.17.0. + +* Fixed [#99][issue-99]: Word broken even though it would fit on line. +* Fixed [#107][issue-107]: Automatic hyphenation is off by one. +* Fixed [#122][issue-122]: Take newlines into account when wrapping. +* Fixed [#129][issue-129]: Panic on string with em-dash. + +## Version 0.9.0 (2017-10-05) + +The dependency on `term_size` is now optional, and by default this +feature is not enabled. This is a *breaking change* for users of +`Wrapper::with_termwidth`. Enable the `term_size` feature to restore +the old functionality. + +Added a regression test for the case where `width` is set to +`usize::MAX`, thanks @Fraser999! All public structs now implement +`Debug`, thanks @hcpl! + +* Fixed [#101][issue-101]: Make `term_size` an optional dependency. + +## Version 0.8.0 (2017-09-04) + +The `Wrapper` struct is now generic over the type of word splitter +being used. This means less boxing and a nicer API. The +`Wrapper::word_splitter` method has been removed. This is a *breaking +API change* if you used the method to change the word splitter. + +The `Wrapper` struct has two new methods that will wrap the input text +lazily: `Wrapper::wrap_iter` and `Wrapper::into_wrap_iter`. Use those +if you will be iterating over the wrapped lines one by one. + +* Fixed [#59][issue-59]: `wrap` could return an iterator. Thanks + @hcpl! +* Fixed [#81][issue-81]: Set `html_root_url`. + +## Version 0.7.0 (2017-07-20) + +Version 0.7.0 changes the return type of `Wrapper::wrap` from +`Vec<String>` to `Vec<Cow<'a, str>>`. This means that the output lines +borrow data from the input string. This is a *breaking API change* if +you relied on the exact return type of `Wrapper::wrap`. Callers of the +`textwrap::fill` convenience function will see no breakage. + +The above change and other optimizations makes version 0.7.0 roughly +15-30% faster than version 0.6.0. + +The `squeeze_whitespace` option has been removed since it was +complicating the above optimization. Let us know if this option is +important for you so we can provide a work around. + +* Fixed [#58][issue-58]: Add a "fast_wrap" function. +* Fixed [#61][issue-61]: Documentation errors. + +## Version 0.6.0 (2017-05-22) + +Version 0.6.0 adds builder methods to `Wrapper` for easy one-line +initialization and configuration: + +```rust +let wrapper = Wrapper::new(60).break_words(false); +``` + +It also add a new `NoHyphenation` word splitter that will never split +words, not even at existing hyphens. + +* Fixed [#28][issue-28]: Support not squeezing whitespace. + +## Version 0.5.0 (2017-05-15) + +Version 0.5.0 has *breaking API changes*. However, this only affects +code using the hyphenation feature. The feature is now optional, so +you will first need to enable the `hyphenation` feature as described +above. Afterwards, please change your code from +```rust +wrapper.corpus = Some(&corpus); +``` +to +```rust +wrapper.splitter = Box::new(corpus); +``` + +Other changes include optimizations, so version 0.5.0 is roughly +10-15% faster than version 0.4.0. + +* Fixed [#19][issue-19]: Add support for finding terminal size. +* Fixed [#25][issue-25]: Handle words longer than `self.width`. +* Fixed [#26][issue-26]: Support custom indentation. +* Fixed [#36][issue-36]: Support building without `hyphenation`. +* Fixed [#39][issue-39]: Respect non-breaking spaces. + +## Version 0.4.0 (2017-01-24) + +Documented complexities and tested these via `cargo bench`. + +* Fixed [#13][issue-13]: Immediatedly add word if it fits. +* Fixed [#14][issue-14]: Avoid splitting on initial hyphens. + +## Version 0.3.0 (2017-01-07) + +Added support for automatic hyphenation. + +## Version 0.2.0 (2016-12-28) + +Introduced `Wrapper` struct. Added support for wrapping on hyphens. + +## Version 0.1.0 (2016-12-17) + +First public release with support for wrapping strings on whitespace. + +[rust-2018]: https://doc.rust-lang.org/edition-guide/rust-2018/ +[`textwrap-macros` crate]: https://crates.io/crates/textwrap-macros + +[issue-13]: https://github.com/mgeisler/textwrap/issues/13 +[issue-14]: https://github.com/mgeisler/textwrap/issues/14 +[issue-19]: https://github.com/mgeisler/textwrap/issues/19 +[issue-25]: https://github.com/mgeisler/textwrap/issues/25 +[issue-26]: https://github.com/mgeisler/textwrap/issues/26 +[issue-28]: https://github.com/mgeisler/textwrap/issues/28 +[issue-36]: https://github.com/mgeisler/textwrap/issues/36 +[issue-39]: https://github.com/mgeisler/textwrap/issues/39 +[issue-58]: https://github.com/mgeisler/textwrap/issues/58 +[issue-59]: https://github.com/mgeisler/textwrap/issues/59 +[issue-61]: https://github.com/mgeisler/textwrap/issues/61 +[issue-81]: https://github.com/mgeisler/textwrap/issues/81 +[issue-99]: https://github.com/mgeisler/textwrap/issues/99 +[issue-101]: https://github.com/mgeisler/textwrap/issues/101 +[issue-107]: https://github.com/mgeisler/textwrap/issues/107 +[issue-122]: https://github.com/mgeisler/textwrap/issues/122 +[issue-129]: https://github.com/mgeisler/textwrap/issues/129 +[issue-140]: https://github.com/mgeisler/textwrap/issues/140 +[issue-141]: https://github.com/mgeisler/textwrap/issues/141 +[issue-151]: https://github.com/mgeisler/textwrap/issues/151 +[issue-158]: https://github.com/mgeisler/textwrap/issues/158 +[issue-176]: https://github.com/mgeisler/textwrap/issues/176 +[issue-177]: https://github.com/mgeisler/textwrap/issues/177 +[issue-193]: https://github.com/mgeisler/textwrap/issues/193 |
