All releases and notable changes will be documented here, using a format similar to the one described by Keep a Changelog.

v1.11.1 (latest release)

Released on 2023-03-01.

Additions:

  • Added a show setenv sub-command.
  • Added an -m flag to the undo command, to allow moving to the last change without undoing it.

  • Fixed the save command, to avoid breaking hard links when writing to existing files.
  • Fixed an issue in the build system causing make distcheck to fail.

Other changes:

v1.11

Released on 2023-01-21.

Additions:

  • Added 15 new command flags:
  • Added a new exec command, (this replaces run, filter, pipe-from, pipe-to, eval, exec-open and exec-tag, which are now just built-in aliases of exec).
  • Added overwrite and optimize-true-color options.
  • Added built-in $RFILE, $FILEDIR and $COLNO variables.
  • Added hi, msg and set arguments to the show command.
  • Added a number argument to the msg command.
  • Added support for 3-digit #rgb colors to the hi command (in addition to the existing #rrggbb support).
  • Added support for binding F13-F20 keys.
  • Added support for parsing alternate encodings of F1-F4 keys (e.g. CSI P) sent by some terminals.
  • Added support for the Kitty keyboard protocol (which significantly increases the number of bindable key combos).
  • Added syntax highlighters for JSON, Go Module (go.mod), G-code and .gitignore files.
  • Added support for binary literals and hex float literals to the C syntax highlighter.
  • Added support for escaped newlines in string literals to the C syntax highlighter.
  • Added support for <<-EOF heredocs to the shell syntax highlighter.

  • Added $PATH, $PWD, $OLDPWD and $DTE_VERSION to the environment section of the dte man page.
  • Added extended support for Contour and WezTerm terminals.
  • Added an AppStream metadata file, which is installed by default when running make install (except on macOS).

Improvements:

  • Updated Unicode support to version 15.
  • Allowed alias and errorfmt entries to be removed, by running the commands with only 1 argument.
  • Improved command auto-completion for alias, bind, cd, redo, move-tab and quit commands.
  • Improved documentation for alias. tag, hi, msg and wsplit commands.
  • Changed quit -p to display the number of modified/unsaved buffers in the dialog prompt.
  • Excluded . and .. from filename auto-completions.
  • Allowed -c <command> options to be used multiple (up to 8) times.
  • Allowed +lineno,colno command-line arguments (in addition to +lineno).
  • Extended line command to accept a lineno,colno argument (in addition to lineno).
  • Limited the size of .editorconfig files to 32MiB.
  • Enabled "enhanced" regex features on macOS, by using the REG_ENHANCED flag when calling regcomp(3).
  • Improved support for the modifyOtherKeys keyboard mode (which increases the number of bindable key combos somewhat), by emitting the escape sequence to enable it at startup.
  • Various improvements to built-in filetype detection.
  • Various performance/efficiency improvements.

Fixes:

  • Fixed a bug that caused searches started by search -r to be incorrectly recorded by macro record.
  • Fixed a bug that caused "broken pipe" errors to occur if the terminal was resized during certain long-running commands (e.g. compile).
  • Fixed several regular expressions in built-in configs that were using non-portable regex features (\s, \b and \w) and causing errors on some systems.
  • Fixed a portability issue that was causing execution of external commands to fail with "function not implemented" errors on some systems (notably Debian GNU/kFreeBSD).

Breaking changes:

  • Changed the default Ctrl+v key binding to paste -a (previously paste -c).
  • Removed the display-invisible global option.
  • Removed the -b flag from the select command.
  • Renamed the built-in coffeescript filetype to coffee.
  • Made the str command in dte-syntax files produce an error if used with single-byte arguments (char should be used instead).

  • Increased the minimum GCC version requirement to 4.8.

Downloads:

v1.10

Released on 2021-04-03.

Additions:

  • Added 7 new commands:
  • Added 12 new command flags:
  • Added 2 new global options:
  • Added an optional exitcode argument to the quit command.
  • Added color, command, env, errorfmt, ft, macro, option, search and wsplit arguments to the show command.
  • Added support for the \e escape sequence in double-quoted command arguments.
  • Added syntax highlighting for Lisp and Scheme files.
  • Added an Alt+Enter key binding to search mode, for performing plain-text searches.
  • Added a Shift+Tab key binding to command mode, for iteratating auto-completions in reverse order.
  • Added %b, %N and %S statusline format specifiers.
  • Added a large confirmation dialog, shown when quit -p is run with unsaved changes.
  • Added the ability to exclude individual commands from command history (by prepending a space character when in command mode).

Improvements:

  • Updated Unicode support to version 13.
  • Bound Ctrl+c to copy -k by default.
  • Re-introduced built-in support for rxvt Ctrl/Alt/Shift key combinations.
  • Fixed the handling of optional capture groups in errorfmt patterns.
  • Improved the legibility of the default color scheme on a wider range of terminals.
  • Changed the filter and pipe-from commands to set $LINES/$COLUMNS to the current window height/width, before running the specified program.
  • Clarified which command flags in the dterc man page are mutually exclusive (by separating them with |).
  • Fixed signal handling, to allow interrupting unresponsive/deadlocked child processes with Ctrl+c.
  • Fixed command-line auto-completion to work properly when option flags are present.
  • Improved the documentation for tag, replace, and errorfmt.
  • Various syntax highlighting improvements.
  • Various terminal compatibility improvements.
  • Various performance improvements.

Breaking changes:

  • Removed support for linking to the system terminfo library. The terminfo database has only been used as a last resort source of information for several releases now. Most terminals that people are likely to be using already have built-in support in the editor, including several capabilities not available from terminfo. This is listed as a breaking change because it may break support for a few archaic hardware terminals (primarily those that aren't ECMA-48 compatible or whose terminfo strings contain mandatory padding).
  • Removed support for vertical tab bars (the tab-bar option was changed from an enum to a Boolean).

Downloads:

v1.9.1

Released on 2019-09-29.

Changes:

  • Fixed make check when running from a release tarball.

Downloads:

v1.9

Released on 2019-09-21.

Additions:

  • Added a new pipe-to command, to complement the existing pipe-from and filter commands.
  • Added a new show command, which can be used to introspect the current values of aliases and bindings.
  • Added a -k flag to the copy command, to allow keeping the current selection after copying.
  • Added a man page entry for the (previously undocumented) eval command.
  • Added new $FILETYPE and $LINENO special variables.
  • Added a display-invisible global option, to allow visible rendering of otherwise invisible Unicode characters.
  • Added an -s command-line flag, for validating custom syntax files.
  • Added a compile-time ICONV_DISABLE=1 option, which disables linking to the system iconv library (but makes the editor UTF-8 only).
  • Added a Desktop Entry file, which can be installed using make install-desktop-file.

Improvements:

  • Updated Unicode support to version 12.1.
  • Modified the errorfmt command, to allow sub-match groups in the regexp pattern to be ignored.
  • Various improvements to syntax highlighting and filetype detection.
  • Various performance optimizations.

Fixes:

  • Fixed a bug that would sometimes cause files to be saved as UTF-8, even if another encoding was specified.

Downloads:

v1.8.2

Released on 2019-04-23.

Changes:

  • Fixed makefile to work with GNU Make 3.81 (which is still used by OS X and Ubuntu 14.04).

Downloads:

v1.8.1

Released on 2019-04-22.

Fixes:

  • Fixed parsing of escaped special characters in command arguments (which was causing Lua syntax highlighting to fail).
  • Removed use of rep (repeat character) control sequence, due to problems caused by certain terminal emulators that claim to be "xterm" but don't support the full set of features in the xterm terminfo(5) entry (notably, the FreeBSD 12 console).

Additions:

  • Show a confirmation prompt if Ctrl+q (quit) is pressed with unsaved changes, instead of a cryptic error message.

Downloads:

v1.8

Released on 2019-04-18.

Additions:

  • Added support for 24-bit RGB terminal colors.
  • Added support for strikethrough terminal attribute.
  • Added support for alias names containing multi-byte Unicode characters.
  • Added refresh command (to force a full screen redraw).
  • Added dte -K command-line option (for keycode debugging).
  • Added support for reading a buffer from stdin at startup.
  • Added support for binding Ctrl/Alt/Shift + F1-F12 on xterm-like terminals.
  • Added -s flag to bol command, to allow moving to beginning of indented text, before moving to beginning of line (a.k.a "smart home").
  • Added -c flag to all cursor movement commands, to allow selecting characters while moving.
  • Added -l flag to up, down, pgup and pgdown commands, to allow selecting whole lines while moving.
  • Added default bindings for various Shift+key combinations, for doing GUI-style text selections.
  • Added key bindings to command mode for deleting/erasing whole words (Alt+Delete and Alt+Backspace).

Improvements:

  • Optimized built-in filetype detection.
  • Fixed cursor interaction with Unicode combining characters.
  • Improved handling of Unicode whitespace and unprintable characters.
  • Updated character class lookup tables to Unicode 11.
  • Expanded documentation for hi and compile commands.
  • Optimized code to reduce editor startup and input latency.

Breaking changes:

  • Changed the bind command to be much more strict when parsing key strings and show an error message when invalid. The caret (^) modifier can now only be used alone (not in combination with other modifiers) and the C-, M- and S- modifiers must be uppercase.
  • Removed support for chained key bindings (e.g. bind '^X c' ...). Commands that aren't bound to simple key combinations can just be accessed via command mode.
  • Removed support for recognizing some Ctrl/Alt/Shift key combinations produced by the rxvt terminal emulator. The key codes produced by rxvt violate the ECMA-48 specification. Users of such terminals are encouraged to configure the key codes to mimic xterm instead.

Downloads:

v1.7

Released on 2018-05-08.

Changes:

  • Added support for opening multiple files using glob patterns (e.g. open -g *.[ch]).
  • Added support for binding more xterm extended key combinations (Ctrl/Meta/Shift + PageUp/PageDown/Home/End).

  • Added Ctrl+H key binding for erase command.
  • Added syntax highlighting for TeX and roff (man page) files.
  • Improved syntax highlighting of Python numeric literals.
  • Improved syntax highlighting for CSS files.
  • Added ft -b command for detecting file types from file basenames.
  • Converted user documentation to Markdown format.

  • Added built-in support for st and rxvt terminals.
  • Fixed some built-in regex patterns to avoid non-portable features.
  • Fixed compiler warnings on NetBSD.
  • Removed tilde expansion of ~username/ from dterc commands, in order to avoid using getpwnam(3) and thereby allow static linking with glibc on Linux.

Downloads:

Downloads:

v1.3

Released on 2017-08-27.

Changes:

  • Added support for binding Ctrl+Alt+Shift+arrows in xterm/screen/tmux.
  • Added support for binding Ctrl+delete/Shift+delete in xterm/screen/tmux.
  • Added the ability to override the default user config directory via the DTE_HOME environment variable.
  • Added syntax highlighting for the Markdown, Meson and Ruby languages.
  • Improved syntax highlighting for the C, awk and HTML languages.
  • Fixed a bug with the close -wq command when using split frames (wsplit).
  • Fixed a segfault bug in git-open mode when not inside a git repo.
  • Fixed a few cases of undefined behaviour and potential buffer overflow inherited from dex.
  • Fixed all compiler warnings when building on OpenBSD 6.
  • Fixed and clarified various details in the man pages.
  • Renamed inc-home and inc-end commands to bolsf and eolsf, for consistency with other similar commands.

  • Added a command-line option to jump to a specific line number after opening a file.
  • Added syntax highlighting for ini, robots.txt and Dockerfile languages.
  • Fixed a compilation error on OpenBSD.
  • Replaced quirky command-line option parser with POSIX getopt(3).
