Release Notes

doy/vt100-rust (vt100)

v0.18.1

Compare Source

Fixed

• actually release the intended changes that were supposed to be in 0.18.0

v0.18.0

Compare Source

Added

• Screen::contents_formatted_basic, which is like
  Screen::contents_formatted, but restricts escape sequences to SGR escapes
  only, and control characters to '\n'.
• Screen::write_contents_formatted_basic, like
  Screen::contents_formatted_basic but writes to any type implementing
  std::fmt::Write instead of returning a String.
• Callbacks::on_scroll, called when a row scrolls off the top of the
  scrollback. This enables capturing terminal output in a streaming fashion.
  Currently this can only be used to obtain the row contents in the "basic
  formatted" style (the same returned by Screen::contents_formatted_basic).
• Parser::DEFAULT_ROWS and Parser::DEFAULT_COLS, set to 24 and 80 (the
  same already used by Parser::default). These have type NonZeroU16.
• Parser::set_size, which is like Screen::set_size but calls the
  on_scroll callback when a row is pushed off the top of scrollback (which
  is now possible due to the other set_size changes).
• Parser::screen_and_callbacks_mut, which returns mutable references to
  both the screen and callbacks object at once. This was not possible with
  the existing methods.
• capture::basic_formatted_to_plain, which converts a basic formatted
  capture (as returned by Screen::contents_formatted_basic) into a plain
  text one without allocating.
• capture::basic_formatted_rows, which splits a basic formatted capture
  into individual rows without allocating.
• capture::basic_formatted_to_plain_indexed, which is like
  capture::basic_formatted_to_plain, but also includes the original index
  of each plain text substring.

Changed

• Bumped MSRV to 1.85 and edition to 2024

• Parser::new and Screen::set_size now take NonZeroU16s instead of
  u16s. Passing 0 for rows or cols was not supported and resulted in
  panics. Additionally, Screen::size now returns NonZeroU16s.

• The following methods of Screen now return/yield strings rather than byte vectors:

  • attributes_formatted
  • contents_diff
  • contents_formatted
  • cursor_state_formatted
  • input_mode_diff
  • input_mode_formatted
  • rows_diff
  • rows_formatted
  • state_diff
  • state_formatted

  The byte vectors were already always UTF-8.

• Screen::set_size resets the scroll region and scrollback offset when the
  size changes, matching the behavior of xterm.

• Screen::set_size has different behavior when the screen height changes.
  Previously, it would discard rows from or add rows to the bottom as needed,
  but this does not match most terminal emulators.

  Now, when the height is decreased, set_size discards rows from the bottom
  only until the cursor is at the bottom. Then, it pushes excess rows from
  the top of the screen into scrollback.

  When the height is increased, set_size pulls rows from scrollback into
  the top of the screen. If scrollback is exhausted and the new height hasn't
  been reached yet, blank rows are added to the bottom.

Fixed

• Fixed no_std support which was inadvertently broken in 0.17.0
• Changed handling of IL and DL sequences when the cursor is outside the
  scroll region. These operations are now no-ops in that case, which is the
  spec-compliant behavior.
• Fixed issue where one-row scroll regions could cause unrelated rows to be
  marked as wrapped or not wrapped.
• Improved the performance of various operations, especially escape sequences
  that insert/delete multiple rows or characters.
• Screen::set_size only clears each row's wrapped when the screen width
  changes. Previously, it would unconditionally clear that flag.
