Display errors and warnings 
To make sure that all error and information reporting to the user is
unified, all instances of `print!`, `eprint!`, `println!` and
`eprintln!` have been removed and replaced by logging.

When `RUST_LOG` is not specified, the default Alacritty logger now also
prints to both the stderr and a log file. The log file is only created
when a message is written to it and its name is printed to stdout the
first time it is used.

Whenever a warning or an error has been written to the log file/stderr,
a message is now displayed in Alacritty which points to the log file
where the full error is documented.

The message is cleared whenever the screen is cleared using either the
`clear` command or the `Ctrl+L` key binding.

To make sure that log files created by root don't prevent normal users
from interacting with them, the Alacritty log file is `/tmp/Alacritty-$PID.log`.

Since it's still possible that the log file can't be created, the UI
error/warning message now informs the user if the message was only
written to stderr. The reason why it couldn't be created is then printed
to stderr.

To make sure the deletion of the log file at runtime doesn't create any
issues, the file is re-created if a write is attempted without the file
being present.

To help with debugging Alacritty issues, a timestamp and the error
level are printed in all log messages.

All log messages now follow this format:
    [YYYY-MM-DD HH:MM] [LEVEL] Message

Since it's not unusual to spawn a lot of different terminal emulators
without restarting, Alacritty can create a ton of different log files.

To combat this problem, logfiles are removed by default after
Alacritty has been closed. If the user wants to persist the log of a
single session, the `--persistent_logging` option can be used. For
persisting all log files, the `persistent_logging` option can be set in
the configuration file

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

  • Option for evenly spreading extra padding around the terminal (window.dynamic_padding)

Changed

  • Extra padding is not evenly spread around the terminal by default anymore

Version 0.2.3

Fixed

  • Mouse cursor alignment issues and truncated last line caused by incorrect padding calculations

Version 0.2.2

Added

  • Add support for Windows
  • Add terminfo capabilities advertising support for changing the window title
  • Allow using scancodes in the key_bindings section
  • When mouse.url.launcher is set, clicking on URLs will now open them with the specified program
  • New mouse.url.modifiers option to specify keyboard modifiers for opening URLs on click
  • Binaries for macOS, Windows and Debian-based systems are now published with GitHub releases
  • The keys F16-F24 have been added as options for key bindings
  • Display notice about errors and warnings inside Alacritty
  • Log all messages to both stderr and a log file in the system's temporary directory
  • New configuration option persistent_logging and CLI flag --persistent-logging, for keeping the log file after closing Alacritty

Changed

  • The colors.cursor.text and colors.cursor.cursor fields are optional now
  • Moved cursor_style to cursor.style
  • Moved unfocused_hollow_cursor to cursor.unfocused_hollow
  • Moved hide_cursor_when_typing to mouse.hide_when_typing
  • Mouse bindings now ignore additional modifiers
  • Extra padding is now spread evenly around the terminal grid

Removed

  • The custom_cursor_colors config field was deleted, remove the colors.cursor.* options to achieve the same behavior as setting it to false
  • The scale_with_dpi configuration value has been removed, on Linux the env variable WINIT_HIDPI_FACTOR=1 can be set instead to disable DPI scaling

Fixed

  • Fixed erroneous results when using the indexed_colors config option
  • Fixed rendering cursors other than rectangular with the RustType backend
  • Selection memory leak and glitches in the alternate screen buffer
  • Invalid default configuration on macOS and Linux
  • Middle mouse pasting if mouse mode is enabled
  • Selections now properly update as you scroll the scrollback buffer while selecting
  • NUL character at the end of window titles
  • DPI Scaling when moving windows across monitors
  • On macOS, issues with Command-[KEY] and Control-Tab keybindings have been fixed
  • Incorrect number of columns/lines when using the window.dimensions option
  • On Wayland, windows will no longer be spawned outside of the visible region
  • Resizing of windows without decorations
  • On Wayland, key repetition works again
  • On macOS, Alacritty will now use the integrated GPU again when available
  • On Linux, the WINIT_HIDPI_FACTOR environment variable can be set from the config now

Version 0.2.1

Added

  • Implement the hidden escape sequence (echo -e "\e[8mTEST")
  • Add support for macOS systemwide dark mode
  • Set the environment variable COLORTERM="truecolor" to advertise 24-bit color support
  • On macOS, there are two new values for the config option window.decorations:
    • transparent - This makes the title bar transparent and allows the viewport to extend to the top of the window.
    • buttonless - Similar to transparent but also removed the buttons.
  • Add support for changing the colors from 16 to 256 in the indexed_colors config section
  • Add save_to_clipboard configuration option for copying selected text to the system clipboard
  • New terminfo entry, alacritty-direct, that advertises 24-bit color support
  • Add support for CSI sequences Cursor Next Line (\e[nE) and Cursor Previous Line (\e[nF)

Changed

  • Inverse/Selection color is now modelled after XTerm/VTE instead of URxvt to improve consistency
  • First click on unfocused Alacritty windows is no longer ignored on platforms other than macOS
  • Reduce memory usage significantly by only initializing part of the scrollback buffer at startup
  • The alacritty terminfo entry no longer requires the xterm definition to be present on the system
  • The default TERM value is no longer static; the alacritty entry is used if available, otherwise the xterm-256color entry is used instead

Removed

  • The terminfo entry alacritty-256color. It is replaced by the alacritty entry (which also advertises 256 colors)

Fixed

  • Rendering now occurs without the terminal locked which improves performance
  • Clear screen properly before rendering of content to prevent various graphical glitches
  • Fix build failure on 32-bit systems
  • Windows started as unfocused now show the hollow cursor if the setting is enabled
  • Empty lines in selections are now properly copied to the clipboard
  • Selection start point lagging behind initial cursor position
  • Rendering of selections which start above the visible area and end below it

Deprecated

  • The config option window.decorations should now use full or none instead of true or false, respectively.

Security

  • Bracketed paste mode now filters escape sequences beginning with \x1b

Version 0.2.0

Added

  • Add a scrollback history buffer (10_000 lines by default)
  • CHANGELOG has been added for documenting relevant user-facing changes
  • Add ClearHistory key binding action and the Erase Saved Lines control sequence
  • When growing the window height, Alacritty will now try to load additional lines out of the scrollback history
  • Support the dim foreground color (echo -e '\033[2mDimmed Text')
  • Add support for the LCD-V pixel mode (vertical screens)
  • Pressing enter on the numpad should now insert a newline
  • The mouse bindings now support keyboard modifiers (shift/ctrl/alt/super)
  • Add support for the bright foreground color

Changed

  • Multiple key/mouse bindings for a single key will now all be executed instead of picking one and ignoring the rest
  • Improve text scrolling performance (affects applications like yes, not scrolling the history)

Fixed

  • Clear the visible region when the RIS escape sequence (echo -ne '\033c') is received
  • Prevent logger from crashing Alacritty when stdout/stderr is not available
  • Fix a crash when sending the IL escape sequence with a large number of lines
