Changelog

• (Breaking) There has been some changes in the server protocol. Make sure to kill the old server process when you update to avoid errors.
• (Breaking) Server load and save commands are now removed. Instead a local file is used to record file selections (e.g. ~/.local/share/lf/files). See the documentation for more information.
• (Breaking) Clients are now disconnected from server on quit. The old server quit command is renamed to quit! to act as a force quit by closing connected client connections first. A new quit command is added to only quit when there are no connected clients left.
• (New) A new autoquit option is added to automatically quit server when there are no connected clients left. This option is disabled by default to keep the old behavior. This is added as an option to avoid respawning server repeatedly when there is often a single client involved but more clients are spawned from time to time.
• (New) A new -single command line flag is added to avoid spawning and/or connecting to server on startup. Remote commands would not work in this case as the client does not connect to a server. Local versions of internal load and sync commands are implemented properly.
• (New) Errors for remote commands are now also shown in the output in addition to the server log file.
• (New) Bright ansi color escape codes (i.e. 90-97 and 100-107) are now supported.
• (Fix) Lookahead size for escape codes are increased to recognize longer escape codes used in some image previewers.
• (Fix) File preview cache is invalidated when the terminal height changes to fill the screen properly.
• (Fix) File preview cache is invalidated when drawbox option changes and true image previews should be triggered to be drawn at updated positions.
• (Fix) A crash scenario is fixed when hidden option is changed.
• (Fix) Pane widths should now be calculated properly when big numbers are used in ratios (by @kmarius).
• (Fix) Special bookmark ' is preserved properly after sync commands (by @kmarius).
• (Fix) On some platforms, a bug has been fixed on tcell side to avoid an extra key press after terminal suspend/resume and the tcell version used in lf is bumped accordingly to include the fix.
• (Fix) Prompt line should now scroll accordingly when the text is wider than the screen.
• (Fix) Text width in the prompt line should now be calculated properly when non-ascii characters are involved.
• (Fix) Erase line escape codes (i.e. \033[K) used in some command outputs should now be ignored properly.

r22

Changelog

• (New) A new -config command line flag is added to use a custom config file path (by @SPFabGerman).
• (New) Current working directory is now exported as PWD environment variable (by @SeerLite). Subshells in symlink directories should now start in their own paths properly.
• (New) Initial working directory is now exported as OLDPWD environment variable.
• (New) A new shellflag option is added to customize the shell flag used for passing commands (i.e. default -c for unix and /c for windows).
• (New) Command cmd-enter during find and find-back now jumps to the first match (by @gotroyb127).
• (New) A new waitmsg option is added to customize the prompt message after shell-wait commands (i.e. default Press any key to continue) (by @gotroyb127).
• (Fix) A regression bug is fixed to print a newline in the prompt message properly after shell-wait commands (by @gotroyb127).
• (Fix) A regression bug is fixed to avoid CPU stuck at 100% when the terminal is closed unexpectedly.
• (Fix) A regression bug is fixed to make shell commands use the alternate screen properly and keep the terminal history after quit.
• (Fix) Enter keypad terminfo sequence is now sent on startup so delete key should be recognized properly in st terminal.

r21

Changelog

• (Breaking) Copy and move do not follow symlinks anymore and copy them as symlinks. Broken symlinks can now be used in copy and move (by @sh1r4s3).
• (New) User name, group name, and hard link counts are now shown in the statusline at the bottom when available (by @kmarius).
• (New) Number of selected, copied, and cut files are now shown in the ruler at the bottom when they are non-zero.
• (New) Hard-coded shell commands with stty (unix) and pause (windows) to implement "Press any key to continue" behavior are now implemented properly with Go terminal handling library. With this change, requirement for a POSIX compatible shell for shell option is now dropped and other shells might be used.
• (Fix) A longstanding issue regarding ui suspend/resume for shell commands in MacOS is now fixed in tcell (by @gdamore).
• (Fix) Renaming a symlink to its target or a symlink to another with the same target should now be handled properly (by @sh1r4s3).
• (Fix) Autocompletion in a directory containing a broken symlink should now work as intended (by @sh1r4s3).
• (Fix) Setting shellopts to empty in the configuration file should not pass an extra empty argument to the shell commands anymore.
• (Fix) Previously given tip to trap SIGPIPE in the preview script to enable caching is now updated in the documentation. Trapping the signal in the preview script avoids sending the signal to the program when enough lines are read. This may result in reading redundant lines escpecially for big files. Recommended method is now to add a trailing || true to each command exiting with a non-zero return code after a SIGPIPE.

r20

Changelog

• (Breaking) A new mouse option is added to enable mouse events. This option is disabled by default to leave mouse events to the terminal. Also unbind mouse events when mouse is enabled should now show unknown mapping error in the message line.
• (Fix) Newline characters in the output of % commands should no longer shift the content up which was a bug introduced in the previous release due to a fix to handle combining characters in texts.
• (Fix) Redundant preview loadings for search and find commands are now avoided (by @neeshy).
• (Fix) Scanner now only considers ascii characters for spaces and digits which should avoid unexpected splits in some non-ascii inputs.

r19

Changelog

• Changes have been made to enable the use of true image previews (by @Naheel-Azawy, @Provessor, and @neeshy). See the documentation and the previews wiki page for more information.
  • (Breaking) Non-zero exit codes should now make the preview volative to avoid caching. Programs that may not behave well to SIGPIPE may trigger this behavior unintentionally. You may trap SIGPIPE in your preview script to get the old behavior.
  • (Breaking) Preview scripts should now get arguments as the current file path, width, height, horizontal position, and vertical position. Note that height is still passed as an argument but its order is changed.
  • (New) A new cleaner option is added to set the path to a file to run when the preview is changed.
  • (Fix) Redundant preview loadings for movement commands are now avoided.
• (Breaking) Expansion %w in promptfmt is changed back to its old behavior without a trailing separator (by @SPFabGerman). Instead, a new expansion %d is added with a trailing separator. Expansion %w is meant to be used to display the current working directory, whereas %d%f is meant to be used to display the current file.
• (Breaking) A new LF_COLORS environment variable is now checked to be able to make lf specific configurations. Also, environment variables for colors are now read cumulatively starting from the default behavior (i.e. default, LSCOLORS, LS_COLORS, LF_COLORS).
• (New) Full path, dir name, file name, and base name matching patterns are added to colors and icons (by @SPFabGerman and @mohkale). See the updated documentation for more information.
• (New) Powershell keybinding example has been added to etc/lfcd.ps1 (by @sitiom).
• (New) Powershell autocompletion script has been added as etc/lf.ps1 (by @sitiom).
• (New) Multiple -command flags can now be given (by @kmarius).
• (New) Basic mouse support has been added. Mouse buttons (e.g. <m-1> for primary button, <m-2> for secondary button, <m-3> for middle button etc.) and mouse wheels (e.g. <m-up> for wheel up, <m-down> for wheel down etc.) can be used in bindings.
• (New) Commands top and bottom are now allowed in cmap mappings in addition to movement commands.
• (Fix) Extension sorting should now handle extensions with different lenghts properly (by @kmarius).
• (Fix) Heuristic used to show info should now take into account number and icons options properly.
• (Fix) Environment variable id is now set to process id instead to avoid two clients getting the same id when launched at the same time (by @edganiukov).
• (Fix) Unicode combining characters in texts should now be displayed properly.

r18

Changelog

• (Breaking) Options ignorecase and ignoredia should now also apply to sorting in addition to searching.
• (Breaking) Option ignoredia is now enabled by default to be consistent with ignorecase.
• (Breaking) Terminal UI library tcell has been updated to version 2 (by @Provessor). This version highlights adding 24-bit true colors on Windows and better support for colors on Unix. Variable TCELL_TRUECOLOR is not required anymore so that terminal themes and true colors can be used at the same time.
• (Breaking) Deprecated option color256 is now removed.
• (New) Two new command line commands cmd-menu-complete and cmd-menu-complete-back are added for completion menu cycling (by @tarasyarema).

• (Fix) Natural sorting is optimized to work faster using less memory.
• (Fix) Files and directories that incorrectly show modification times in the future (e.g. Linux builtin exFAT driver) should not cause cpu hogging anymore.
• (Fix) Keybinding example in etc/lfcd.fish is now updated to avoid hanging in shell commands (by @crivaronicolini).
• (Fix) Using bottom command immediately after startup should not crash the program anymore.
• (Fix) Changing sorting options during sorting operations should not crash the program anymore.
• (Fix) Output in piping shell commands now uses lazy redrawing so that verbose commands should not block the program anymore.
• (Fix) Server is now daemonized properly on Unix so that it is not killed anymore when the controlling terminal is killed (by @neeshy).

r17

Changelog

• Terminal UI library has been changed from termbox-go to tcell as the former has been unmaintained for a while (by @Provessor). Some of the changes are listed below, though the list may not be complete as this is a relatively big change.
  • (Breaking) Some special key names are changed to be consistent with tcell documentation (e.g. <bs> renamed to <backspace>). On the other hand, there are also additional keybindings that were not available before (e.g. <backtab> for Shift+Tab). You can either check tcell documentation for the list of keys or hit the key combination in lf to read the name of the key from the unknown mapping error message.
  • (New) 24-bit true colors are now supported on unix systems. See the updated documentation for more information. There is an ongoing version 2.0 development in tcell that we plan to switch once it becomes stable and it is expected to add support for true colors in Windows console as well.

• (Fix) Errors from failed shell commands should not be overwritten by file information anymore.
• (Fix) Server can now also be started automatically when the program is called with a relative path, which was a regression due to a bug fix in a previous release (by @Provessor).
• (Fix) Environment variables are now exported automatically for preview scripts without having to call a shell command first (by @gotroyb127).
• (Fix) Escape key can now be bind to a key for when it is used on it own and not to escape a keybind combination, which was a regression due to a bug fix in a previous release (by @YerinAlexey).
• (Fix) Changing option hiddenfiles should now automatically trigger directory updates when necessary.

r16
