-# Changelog
-
-## [0.16.2] - 2025-07-11
-
-### Fixed
-
-* Fixed potential cursor out of bounds when using decrc after resizing. (#13)
-
-## [0.16.1] - 2025-07-10
-
-### Changed
-
-* Reverted to the 2021 edition for now.
-
-## [0.16.0] - 2025-07-08
-
-### Added
-
-* `Parser::process_cb`, which works the same as `Parser::process` except that
- it calls callbacks during parsing when it finds a terminal escape which is
- potentially useful but not something that affects the screen itself.
-* Support for xterm window resize request escape codes, via the new callback
- mechanism.
-* Support for dim formatting. (Daniel Faust, #9)
-* Support for CNL/CPL escape codes. (Danny Weinberg, #10)
-* Support for OSC 52 (clipboard manipulation).
-
-### Removed
-
-* These methods on `Screen` have been removed in favor of the new callback
- API described above:
- * `title_formatted`
- * `title_diff`
- * `title`
- * `icon_name`
- * `bells_diff`
- * `audible_bell_count`
- * `visual_bell_count`
- * `errors`
-* Additionally, unhandled escape sequences no longer log to STDERR; they
- instead call various callback methods which can be defined to log if
- desired.
-* `Cell` no longer implements `Default`.
-* `Screen` no longer implements `vte::Perform`.
-
-### Changed
-
-* `Parser::set_size` and `Parser::set_scrollback` have been moved to methods
- on `Screen`, and `Parser::screen_mut` was added to get a mutable reference
- to the screen.
-* `Cell::contents` now returns `&str` instead of `String`, eliminating an
- allocation in many cases. (Chris Olszewski, #14)
-
-### Fixed
-
-* Fixed some issues with calculating scrollback offsets correctly in
- `Grid::visible_rows`. (rezigned, #11)
-
-## [0.15.2] - 2023-02-05
-
-### Changed
-
-* Bumped dependencies
-
-## [0.15.1] - 2021-12-21
-
-### Changed
-
-* Removed a lot of unnecessary test data from the packaged crate, making
- downloads faster
-
-## [0.15.0] - 2021-12-15
-
-### Added
-
-* `Screen::errors` to track the number of parsing errors seen so far
-
-### Fixed
-
-* No longer generate spurious diffs in some cases where the cursor is past the
- end of a row
-* Fix restoring the cursor position when scrolled back
-
-### Changed
-
-* Various internal refactorings
-
-## [0.14.0] - 2021-12-06
-
-### Changed
-
-* Unknown UTF-8 characters default to a width of 1, rather than 0 (except for
- control characters, as mentioned below)
-
-### Fixed
-
-* Ignore C1 control characters rather than adding them to the cell data, since
- they are non-printable
-
-## [0.13.2] - 2021-12-05
-
-### Changed
-
-* Delay allocation of the alternate screen until it is used (saves a bit of
- memory in basic cases)
-
-## [0.13.1] - 2021-12-04
-
-### Fixed
-
-* Fixed various line wrapping state issues
-* Fixed cursor positioning after writing zero width characters at the end of
- the line
-* Fixed `Screen::cursor_state_formatted` to draw the last character in a line
- with the appropriate drawing attributes if it needs to redraw it
-
-## [0.13.0] - 2021-11-17
-
-### Added
-
-* `Screen::alternate_screen` to determine if the alternate screen is in use
-* `Screen::row_wrapped` to determine whether the row at the given index should
- wrap its text
-* `Screen::cursor_state_formatted` to set the cursor position and hidden state
- (including internal state like the one-past-the-end state which isn't visible
- in the return value of `cursor_position`)
-
-### Fixed
-
-* `Screen::rows_formatted` now outputs correct escape codes in some edge cases
- at the beginning of a row when the previous row was wrapped
-* VPA escape sequence can no longer position the cursor off the screen
-
-## [0.12.0] - 2021-03-09
-
-### Added
-
-* `Screen::state_formatted` and `Screen::state_diff` convenience wrappers
-
-### Fixed
-
-* `Screen::attributes_formatted` now correctly resets previously set attributes
- where necessary
-
-### Removed
-
-* Removed `Screen::attributes_diff`, since I can't actually think of any
- situation where it does a thing that makes sense.
-
-## [0.11.1] - 2021-03-07
-
-### Changed
-
-* Drop dependency on `enumset`
-
-## [0.11.0] - 2021-03-07
-
-### Added
-
-* `Screen::attributes_formatted` and `Screen::attributes_diff` to retrieve the
- current state of the drawing attributes as escape sequences
-* `Screen::fgcolor`, `Screen::bgcolor`, `Screen::bold`, `Screen::italic`,
- `Screen::underline`, and `Screen::inverse` to retrieve the current state of
- the drawing attributes directly
-
-## [0.10.0] - 2021-03-06
-
-### Added
-
-* Implementation of `std::io::Write` for `Parser`
-
-## [0.9.0] - 2021-03-05
-
-### Added
-
-* `Screen::contents_between`, for returning the contents logically between two
- given cells (for things like clipboard selection)
-* Support SGR subparameters (so `\e[38:2:255:0:0m` behaves the same way as
- `\e[38;2;255;0;0m`)
-
-### Fixed
-
-* Bump `enumset` to fix a dependency which fails to build
-
-## [0.8.1] - 2020-02-09
-
-### Changed
-
-* Bumped `vte` dep to 0.6.
-
-## [0.8.0] - 2019-12-07
-
-### Removed
-
-* Removed the unicode-normalization feature altogether - it turns out that it
- still has a couple edge cases where it causes incorrect behavior, and fixing
- those would be a lot more effort.
-
-### Fixed
-
-* Fix a couple more end-of-line/wrapping bugs, especially around cursor
- positioning.
-* Fix applying combining characters to wide characters.
-* Ensure cells can't have contents with width zero (to avoid ambiguity). If an
- empty cell gets a combining character applied to it, default that cell to a
- (normal-width) space first.
-
-## [0.7.0] - 2019-11-23
-
-### Added
-
-* New (default-on) cargo feature `unicode-normalization` which can be disabled
- to disable normalizing cell contents to NFC - it's a pretty small edge case,
- and the data tables required to support it are quite large, which affects
- size-sensitive targets like wasm
-
-## [0.6.3] - 2019-11-20
-
-### Fixed
-
-* Fix output of `contents_formatted` and `contents_diff` when the cursor
- position ends at one past the end of a row.
-* If the cursor position is one past the end of a row, any char, even a
- combining char, needs to cause the cursor position to wrap.
-
-## [0.6.2] - 2019-11-13
-
-### Fixed
-
-* Fix zero-width characters when the cursor is at the end of a row.
-
-## [0.6.1] - 2019-11-13
-
-### Added
-
-* Add more debug logging for unhandled escape sequences.
-
-### Changed
-
-* Unhandled escape sequence warnings are now at the `debug` log level.
-
-## [0.6.0] - 2019-11-13
-
-### Added
-
-* `Screen::input_mode_formatted` and `Screen::input_mode_diff` give escape
- codes to set the current terminal input modes.
-* `Screen::title_formatted` and `Screen::title_diff` give escape codes to set
- the terminal window title.
-* `Screen::bells_diff` gives escape codes to trigger any audible or visual
- bells which have been seen since the previous state.
-
-### Changed
-
-* `Screen::contents_diff` no longer includes audible or visual bells (see
- `Screen::bells_diff` instead).
-
-## [0.5.1] - 2019-11-12
-
-### Fixed
-
-* `Screen::set_size` now actually resizes when requested (previously the
- underlying storage was not being resized, leading to panics when writing
- outside of the original screen).
-
-## [0.5.0] - 2019-11-12
-
-### Added
-
-* Scrollback support.
-* `Default` impl for `Parser` which creates an 80x24 terminal with no
- scrollback.
-
-### Removed
-
-* `Parser::screen_mut` (and the `pub` `&mut self` methods on `Screen`). The few
- things you can do to change the screen state directly are now exposed as
- methods on `Parser` itself.
-
-### Changed
-
-* `Cell::contents` now returns a `String` instead of a `&str`.
-* `Screen::check_audible_bell` and `Screen::check_visual_bell` have been
- replaced with `Screen::audible_bell_count` and `Screen::visual_bell_count`.
- You should keep track of the "since the last method call" state yourself
- instead of having the screen track it for you.
-
-### Fixed
-
-* Lots of performance and output optimizations.
-* Clearing a cell now sets all of that cell's attributes to the current
- attribute set, since different terminals render different things for an empty
- cell based on the attributes.
-* `Screen::contents_diff` now includes audible and visual bells when
- appropriate.
-
-## [0.4.0] - 2019-11-08
-
-### Removed
-
-* `Screen::fgcolor`, `Screen::bgcolor`, `Screen::bold`, `Screen::italic`,
- `Screen::underline`, `Screen::inverse`, and `Screen::alternate_screen`:
- these are just implementation details that people shouldn't need to care
- about.
-
-### Fixed
-
-* Fixed cursor movement when the cursor position is already outside of an
- active scroll region.
-
-## [0.3.2] - 2019-11-08
-
-### Fixed
-
-* Clearing cells now correctly sets the cell background color.
-* Fixed a couple bugs in wide character handling in `contents_formatted` and
- `contents_diff`.
-* Fixed RI when the cursor is at the top of the screen (fixes scrolling up in
- `less`, for instance).
-* Fixed VPA incorrectly being clamped to the scroll region.
-* Stop treating soft hyphen specially (as far as i can tell, no other terminals
- do this, and i'm not sure why i thought it was necessary to begin with).
-* `contents_formatted` now also resets attributes at the start, like
- `contents_diff` does.
-
-## [0.3.1] - 2019-11-06
-
-### Fixed
-
-* Make `contents_formatted` explicitly show the cursor when necessary, in case
- the cursor was previously hidden.
-
-## [0.3.0] - 2019-11-06
-
-### Added
-
-* `Screen::rows` which is like `Screen::contents` except that it returns the
- data by row instead of all at once, and also allows you to restrict the
- region returned to a subset of columns.
-* `Screen::rows_formatted` which is like `Screen::rows`, but returns escape
- sequences sufficient to draw the requested subset of each row.
-* `Screen::contents_diff` and `Screen::rows_diff` which return escape sequences
- sufficient to turn the visible state of one screen (or a subset of the screen
- in the case of `rows_diff`) into another.
-
-### Changed
-
-* The screen is now exposed separately from the parser, and is cloneable.
-* `contents_formatted` now returns `Vec<u8>` instead of `String`.
-* `contents` and `contents_formatted` now only allow getting the contents of
- the entire screen rather than a subset (but see the entry for `rows` and
- `rows_formatted` above).
-
-### Removed
-
-* `Cell::new`, since there's not really any reason that this is useful for
- someone to do from outside of the crate.
-
-### Fixed
-
-* `contents_formatted` now preserves the state of empty cells instead of
- filling them with spaces.
-* We now clear the row wrapping state when the number of columns in the
- terminal is changed.
-* `contents_formatted` now ensures that the cursor has the correct hidden state
- and location.
-* `contents_formatted` now clears the screen before starting to draw.
-
-## [0.2.0] - 2019-11-04
-
-### Changed
-
-* Reimplemented in pure safe rust, with a much more accurate parser
-* A bunch of minor API tweaks, some backwards-incompatible
-
-## [0.1.2] - 2016-06-04
-
-### Fixed
-
-* Fix returning uninit memory in get_string_formatted/get_string_plaintext
-* Handle emoji and zero width unicode characters properly
-* Fix cursor positioning with regards to scroll regions and wrapping
-* Fix parsing of (ignored) character set escapes
-* Explicitly suppress status report escapes
-
-## [0.1.1] - 2016-04-28
-
-### Fixed
-
-* Fix builds
-
-## [0.1.0] - 2016-04-28
-
-### Added
-
-* Initial release

-# vt100
-
-This crate parses a terminal byte stream and provides an in-memory
-representation of the rendered contents.
-
-## Overview
-
-This is essentially the terminal parser component of a graphical terminal
-emulator pulled out into a separate crate. Although you can use this crate
-to build a graphical terminal emulator, it also contains functionality
-necessary for implementing terminal applications that want to run other
-terminal applications - programs like `screen` or `tmux` for example.
-
-## Synopsis
-
-```rust
-let mut parser = vt100::Parser::new(24, 80, 0);
-
-let screen = parser.screen().clone();
-parser.process(b"this text is \x1b[31mRED\x1b[m");
-assert_eq!(
- parser.screen().cell(0, 13).unwrap().fgcolor(),
- vt100::Color::Idx(1),
-);
-
-let screen = parser.screen().clone();
-parser.process(b"\x1b[3D\x1b[32mGREEN");

-//! This crate parses a terminal byte stream and provides an in-memory
-//! representation of the rendered contents.
-//!
-//! # Overview
-//!
-//! This is essentially the terminal parser component of a graphical terminal
-//! emulator pulled out into a separate crate. Although you can use this crate
-//! to build a graphical terminal emulator, it also contains functionality
-//! necessary for implementing terminal applications that want to run other
-//! terminal applications - programs like `screen` or `tmux` for example.
-//!
-//! # Synopsis
-//!
-//! ```
-//! let mut parser = vt100::Parser::new(24, 80, 0);
-//!
-//! let screen = parser.screen().clone();
-//! parser.process(b"this text is \x1b[31mRED\x1b[m");
-//! assert_eq!(
-//! parser.screen().cell(0, 13).unwrap().fgcolor(),
-//! vt100::Color::Idx(1),
-//! );
-//!
-//! let screen = parser.screen().clone();
-//! parser.process(b"\x1b[3D\x1b[32mGREEN");
-//! assert_eq!(
-//! parser.screen().contents_formatted(),
-//! &b"\x1b[?25h\x1b[m\x1b[H\x1b[Jthis text is \x1b[32mGREEN"[..],
