Version 3.1 ("Recovering inertia") - 2017/06/25:
+ New features
- support for new compression programs: lzip, lz4
+ Changes & improvements:
- Improved resources files (docs, default keys and theme) installation
and loading at runtime
+ Fixes:
- when installing data files with pip >7.0 & wheel.
Thanks to Jean-François Bercher
- PowerCLI: error message is always shown when command finishes.
Thanks to Jean Terrier for the report
- filters: glob when parent dir contains special chars (BB issue #5).
Thanks to Viktor Vad for the report
- lfm crashes when terminal is too narrow (BB issue #4).
Thanks to Wayne Tan for the report
Version 3.0 ("Only you") - 2015/10/23:
+ About the code
- almost completely rewritten from scratch
. it hasn't been tested as much as lfm v2.x series on non-linux OS
- requires Python v3.4+
- pyview, the file viewer, has been removed from lfm package
- configuration location has changed to a new directory and files:
~/.config/lfm/{lfm.ini, lfm.keys, lfm.theme, lfm.history}
+ New features
- fully customizable themes (colors)
- fully customizable key bindings
. allow Alt-key shorcuts (A-)
. only for main window (not for dialogs)
- files filters (using globs)
. information in pane frame: ".F" => show dotfiles, active filters
. filters are a property of a tab, they remain active even when chdir
. Ctrl-f: edit current filter
. Some examples:
. "*.png,*.jpg" => hide all PNG and JPEG files
. "*.jpg,!*shot*" => hide all JPEG files except those with 'shot'
in the name
. "*,!*py" => hide all except python source files
- up to 35 bookmarks (0-9, a-z)
. b: go to bookmark, B: set bookmark, C-d: select bookmark
. fix: don't delete bookmark at start if path does not exist
- nested archive handling (vfs inside vfs) works now
- added optional support for filenames with wide chars, f.e. East Asian
. to enable, set 'use_wide_chars' flag in configuration or use -w
command line flag
. it's disabled by default for performance
. it's not perfect, but it mostly works
- there are 2 different versions of move_file to chose from in the key
bindings file:
. move_file: old implementation
. move_file2: alternative version using shtutil.move instead of
copy & delete. Faster but less control of errors
- new action: redraw screen (default key A-r)
+ Changes & improvements (vs v2.x):
- chmod & chown/chgrp are 2 different actions now
- cursor_goto_file (C-s): find text pattern (no regex or glob) in the whole
file name, not at the beginning as v2.x
- cursor_goto_file_1char (A-s): go to file by 1st letter of name
(old C-s behaviour)
- bookmarks have new key bindings:
b: go to bookmark, B: set bookmark, C-d: select bookmark
- PowerCLI:
. ending command with % must be $ now
. added new date variables: dm, dc, da, dn
. old $d variable is $p now
- find/grep: panelize = create vfs with matched files
. if rebuild: all files modifications or deletions are translated to
original directory so be careful!
- pyview, the file viewer, has been removed from lfm package
+ Fixes in v3.0 (vs v2.x):
- nested archive handling (vfs inside vfs) works now
- find & grep with spaces in file name
- wide chars file names support (f.e. Eastern languages) => lfm -w
- sort by size after show dirs size
- move_file: not overwritten files in destination are not deleted
Version 2.3 ("Wow, less than a year!") - 2011/05/21:
+ About the code
- lfm needs python version 2.5 or upper now
+ New features
- PowerCLI, an advanced command line interface with completion, persistent
history, variable substitution and many other useful features.
As this is a very powerful tool, read the documentation for examples
- history
. use different types of history lists: path, file, glob, grep, exec, cli
for the different forms and actions
. persistent history between sessions => ~/.lfm_history
. controlled by a flag in configuration
- find/grep
. configuration options for ignorecase and regex
. sort results
. show results as FILE:lineno
. much faster
- show diff between xxx.orig and xxx files
- tar files compress/uncompress
- messages.EntryLine has been rewritten, with many new key shorcuts. This is
the core behind most of the forms lfm shows when asking for anything.
Consult the documentation
+ Minor changes
- reorganize "un/compress file" and "compress directory xxx" in file_menu
- config: sort entries when saving
- improve lad/save handling of new options not present in ~/.lfmrc
- added new extensions
- messages.error rewritten to offer better messages
- added some new key shortcuts messages.SelectItem
+ Documentation
- added a note about python v2.5+ is needed from now on
- 'lfm' shell function: change "$*" to "$@" to properly handle paths
containg spaces
- FAQ: added information about fuse to mount ssh, ftp, smb and webdav
- reorganized and fixed key bindings section
- documented .lfmrc contents
- added link to public BitBucket repository
+ lots of bugs fixed:
- pyview:
. last char is not shown if file size is small
. last line and wrap: cursor_down or page_next
. when number of lines == window height
- ncurses v5.8 doesn't accept 0 as width or height
- UI crashes:
. time string could contain non-ascii characters (reported by Martin Steigerwald)
. when filenane length is large in full pane mode
. MenuWin, SelectItem: ellipsize entries if bigger than screen width
- find or find&grep:
. pass "-type f" to find as ".#filename" are temporary emacs files/links
that break search
. show wrong matches if results contain directories or files with spaces
. file->goto_file: move to correct page
- copy/move "/file" to "/anydir/anyplace" fails, trying to copy/move to "/"
- executing non-ascii programname or args
- convoluted issue with link to directory in corner cases (reported by Xin Wang)
- rename/backup ".." crashes
- we should not compress ".."
- create_link, edit_link: don't show error if canceled
- only store one copy of the same entry in history
- tree: "disable" colors of active panel, "enable" at end
- Config.save: work with unicode, only convert to encoding when saving
Version 2.2 ("Approaching perfection") - 2010/05/22:
+ New features
- use 2 progress bars in copy/move/delete dialog, one for files count
and other for files size
- added recursive chmod chown chgrp
- faster cursor movement
. Ctrl-l: center cursor in panel, so now edit-link is in 'L'
. Ctrl-cursor_up, Ctrl-P: move cursor 1/4th of page up
. Ctrl-cursor_down, Ctrl-N: move cursor 1/4th of page down
. P: move cursor 1/4th of page up in other panel
. N: move cursor 1/4th of page down in other panel
- file_menu new feature: a -> backup file. You can specify the extension
to use in .lfmrc
- added support for .xz compressed files
- Unicode & Encodings
. rewrite all internals to use unicode strings, but employ terminal
encoding (f.e. utf-8) to interact with the user or to display contents
in ncurses functions or to run commands in shell
. when lfm detects a file with invalid encoding name it asks the user to
convert it (can be automatic with the proper option in the
configuration, automatic_file_encoding_conversion, default 0 (ask)).
If not converted, lfm will display the file but won't operate on it.
. try more encodings when we get a filename with strange characters
. lfm will check and require a valid encoding before running
- Pyview:
. completely rewritten. Code is shorter and more beautiful now
Uses a new FileCache class to accelerate the retrieving of file lines
. displays contents between 2 and 4 times faster
. new command line flag -s/--stdin to force reading from stdin.
Now pyview doesn't wait for stdin input by default, so it starts much
faster. eg. $ ps efax | pyview -s
+ Minor changes
- add color entries for directories and exe_files
- expand ~ to user home
- make Tree follow .dotfiles behaviour, new keybinding Ctrl-H
- dialogs are bigger now
- show filesystem info rewritten
- show file info rewritten, now it shows correctly information
from fuse-mounted volumes
- added new "ebook" category, filetypes and formats
+ About the code
- since python v2.6+, popen* is deprecated, so make lfm check python
version and use popen* or subprocess accordingly
- correct some python idioms
- clean code
+ Documentation
- Added "Files Name Encoding" and "FAQ" sections
- Added information about keybindings in permissions window
- Updated some other minor changes: wide char support, vfs, thanks
+ lots of bugs fixed:
- file system information was not showed correctly sometimes
- devices major and minor numbers were not showed correctly
- crash in goto_dir if there aren't any historic entries
- crash in a void EntryLine after pressing BACKSPACE on some platforms
- unzip => overwrite files without prompting ("unzip -o" option) to avoid
ethernal waiting, as messages can not be seen by user
- fix make_dir error message
- recompressing a vfs compressed file leave some garbage on temporary dir
- don't try to copy fifo/socket/block-dev/char-dev files
- crash when we don't have enough permissions to write to dest
- show_dirs_size: don't show in stderr if we don't have perms for a dir
- can't browse /home/<user> as root if .gvfs is present
- EntryLine: non-ascii chars are not showed correctly
- lfm crashes with invalid encoding filenames
- increment owner and group space to avoid ugly look in 1-pane view
- when moving files, don't delete source if some error or if we don't
overwrite destination
Version 2.1 ("What do you want for Christimas?") - 2008/12/21:
+ Ctrl-H now show/hide dot files
+ Ctrl-Y display directories history
+ It's now posible to move the cursor in the non-active pane
Consult the documentation for available keys and actions
This behaviour is de/activated with Ctrl-W
+ added support for .7z compressed files
+ swapped F2 and F12 keys, now F2 rename files and F12 show file menu
+ new key shortcuts in dialogs. Read docs
+ speed up cursor movement
+ lots of code cleaning and refactoring
+ and fixed lot of bugs, some of them:
- setup.py: change Iñigo for Inigo to avoid problems when installing
- sorting by None doesn't crash anymore
- MenuWin dialog crashed when title length was greater than length of
entries to show
Version 2.0 ("Nine 1/2 weeks... ok, ok, and 3 years") - 2007/09/03:
+ tabs implemented
+ color files by extension [Andrey Skvortsov]
+ new IPC code and API; more flexible, powerful and stable
+ new un/compress vfs API, added support for .zip and .rar files
+ make sort mode per tab, not globally
+ support locale [Andrey Skvortsov]
+ speed up loading directory contents
+ speed cursor movement, don't waste much CPU
+ use logging module in lfm and pyview for debugging
+ overwrite_all_none: yes, all, no => new options: "none", "skip all""
+ rewrite/refactor most of code to make lfm more robust and clean
+ preferences:
- change file name preferences.py => config.py
- use ConfigParser
+ use tempfile secure versions mkdtemp() and mkstemp()
+ added man pages [Sebastien Bacher]
+ use reST for documentation
+ check for python version 2.3 or higher in lfm and pyview
+ upgraded to GPL v3 license
+ and fixed lot of bugs, some of them:
- general:
. delete garbage if user stops action
. run 'do_special_view_file' as dettached from lfm window
. path expand in bookmarks ("~/") [Andrey Skvortsov]
. an ugly traceback crash appears when user starts "lfm path" and has
no permissions to enter. Show error message and default to current
directory
. lfm crashes when filename is not encoded with same codec than
g_encoding utils.{decode|encode}. Needs curses module linked against
ncursesw to work properly
. sort_mix_cases = 1 performance degrades on larger dirs.
Reported by Andrey Skvortsov
. escape filenames with chars $ ". Reported by Andrey Skvortsov
- user interface:
. maximize/minimize window don't crash lfm anymore
. dialogs appear at bad position after terminal is resized
. handle window resize in Tree mode
. refresh display after canceling completion dialog
. "the size of the right pane does not fill the last column in
terminal if their number is odd" [Andrey Skvortsov]
. fix crash when "df" shows entries in two different lines (device
name is too large, f.e. in linux lvm2 volumes)
. if you try to enter a directory with insufficient permissions, after
the error message is closed the cursorline refreshes to the first line
- compress:
. added -i flag (--ignore-zeros) flag to tar [Andrey Skvortsov]
. standard tar needs - for flags
- vfs:
. vfs.py: regenerate_file, if user stops process, tempfile can't be
deleted
- find/grep:
. escape special chars (- \ ( ) [ ]) in patterns
. don't crash when find/grep returns no results
. bug when matches occur in binary files
- pyview:
. goto line 0 in pyview showed a blank screen
. crash in file info if filename is too long
Version 1.0 was never publically released - 2006
Version 0.92 was never publically released - 2005
Version 0.91 ("It rocks... yeah!") - 2004/06/30:
+ quite stable and robust, doesn't crash
+ faster
+ new option: show_dotfiles flag
+ new option: detach_terminal_at_exec flag: useful f.e. if you
want to run elinks as web browser attached to lfm terminal
+ file associations and applications can be configured in preferences
+ now each application has only 1 associated program, *breaking old .lfmrc*
+ perms dialog: users & groups sorted alphabetically
+ uncompress in other panel
+ resizing terminal works in lfm, pyview. Be careful with dialogs
+ columns size eliminated from preferences
+ 1-panel view redesigned
+ ESC closes dialogs, not lfm or pyview
+ Ctrl-D: select bookmark dialog
+ code reorganized: actions.py, vfs.py
+ added classifiers to setup.py script
Version 0.90 was never publically released
Version 0.9 ("...and the day arrived") - 2002/09/05:
+ ZIP files can be un/compressed now. ZIP vfs works too
+ added 'rebuild vfs' and 'rebuild_vfs' question / option. Configurable.
There is no need to wait until vfs file is rebuilt
+ Applied some good patches from Bartosz Oler (liar AT furrynet DOT org):
1. colors customization: Now you can customize the colors lfm use in
the configuration file, 'colors' section. Each color is defined by
a string with its name. It looks like this:
element foreground_color background_color
2. Allow preferences values to contain colons in the configuration file.
3. Lack of a bookmark's definition shouldn't be an error.
+ pyview: new features:
- read from stdin
- go to / set bookmarks
- open shell
+ pyview doesn't show blank screen a the end of the file, now it shows last
line
+ lfm works now with "from __future__ import division", prepared for Python 3.0
+ set python2 as default interpreter for setup.py, lfm, lfm.py, pyview and
pyview.py
+ my email address has changed <inigoserna AT telefonica DOT net>
+ Bugs fixes. See ChangeLog for complete list
- lfm:
* create temporary files with mask 0066 and directories with perms
0700, so only owner can read/write them
* avoid zombie processes when using 'fork' (now fork twice or threads)
* show correct filename when an error occurs while uncompressing file
* don't compress '..' directory
* when lfm exits after checking command line options, make 'lfm' shell
script don't show path error
* when un/compressing files cursorbar must remain in the same file
* when, at start, lfm can't enter into a dir due to directory permissions
* crash if len(line) == width of cursorbar window
* don't append '*' to historic in entries
* fix cursor bar position after sorting
- pyview:
* when user hasn't permissions to read file, exit gracefully instead
of crashing
* last char in file is not showed
Version 0.8 ("Close to Paradise") - 2002/03/04:
+ Implemented VFS feature to enter into .tar.gz and .tar.bz2 files
+ Panelize vfs option in find/grep implemented
+ Tree panel implemented
+ 'lfm' and 'pyview' are simple scripts now, not just a copy of the .py files.
__init__.py contains global variables now
+ A new message window is used to show work in progress, in place of a
message in status bar. 'run_thread' function has been cleaned too
+ Copy / move features now use my own function to walk trees, instead of
'shutil.copytree' which originates some problems and bugs
+ In ChangePermissions window, the cursor movement is circular now
+ Change copyright date to years 2001-2
+ I don't need a crypt / uncrypt feature, so eliminated from TODO list
+ Many bugs fixes and functions rewrites. See ChangeLog for complete list
- lfm:
* if panel2 shows 'a' file in panel, and in panel1 'a' is moved or
deleted, lfm crashes
* after moving a file cursor goes to next directory as deletion does
* catching an exception after not been able to copy => it crashed
when trying to delete copied files
* "messages.SelectItem, messages.FindfilesWin, messages.MenuWin,
messages.ChangePerms: upperleft corner disappears"
* findgrep: fix bug: if selected file has a ':' in name
- pyview:
* changing 'addch' by 'addstr' shows individual chars >= 0xA0 (meta
chars) correctly, neither in reversed video or as 2 chars
* "if wrap mode => fix prev/next page & up/down cursor". Now
they move to screen lines, not to physical lines
Version 0.7 ("Hello Darling, I'm here") - 2001/11/30:
+ 'pyview', a new pager/viewer for use with lfm or standalone,
internally or externally. It is used as default pager too.
Some features: Text / Hex view, backwards & forwards search,
goto line/byte, un/wrap mode, documentation, ...
+ Rewrite 'show filesystems info' to use internal viewer
+ New 'run_thread' function in which almost every proccess is executed,
so they can be stopped and there is a working signal too.
'do_something_on_file' does not use it
+ Implemented 'show file info'
+ Check errors when un/compressing
+ Support for .bz2
+ Removed tar 'v' flag in un/compressing
+ Fixed completition, it should work perfectly now

+ Fix cursor position after deleting files
+ Default configuration is now saved inmediately
+ Many other bugs fixed again (see ChangeLog)
Version 0.6 was never publically released
Version 0.5 ("Last call to London") - 2001/08/07:
+ F2 file menu, added many functions
+ F9 general menu, added many functions
+ Implemented find and grep
+ File permissions, owner and group has a window now
