Tree Changelog

Version 1.6.0

• Re-org of code into multiple files, split HTML and Unix listdir() into separate functions, various code cleanups and optimizations.
• Fixed a memory leak in listdir() when memory was allocated early and not freed before function exit.
• Fixed possible buffer overflow where symbolic links are followed.
• Fixed links printing "argetm" before the name of the link when the LINK setting for DIR_COLORS is set to target (Markus Schnalke <meillo@marmaro.de>)
• More fully support dir colors -- added support for su, sg, tw, ow, & st options (and "do" in theory).
• Use the environment variable "TREE_COLORS" instead of "LS_COLORS" for color information if it exists.
• Added --si flag to print filesizes in SI (powers of 1000) units (Ulrich Eckhardt)
• Added -Q to quote filenames in double quotes. Does not override -N or -q.
• Control characters are no longer printed in carrot notation, but as backslashed octal, ala ls, except for codes 7-13 which are printed as \a, \b, \t, \n, \v, \f and \r respectively. Spaces and backslashes are also now backslashed as per ls, for better input to scripts unless -Q is in use (where "'s are backslashed.) (Ujjwal Kumar)
• Added -U for unsorted listings (directory order).
• Added -c for sorting by last status change (ala ls -c).
• --dirsfirst is now a meta-sort and does not override -c, -v, -r or -t, but is disabled by -U.
• After many requests, added the ability to process the entire tree before emitting output. Used for the new options --du, which works like the du command: sums the amount of space under each directory and prints a total amount used in the report and the --prune option which will prune all empty directories from the output (makes the -P option output much more readable.) It should be noted that this will be slow to output when processing large directory trees and can consume copious amounts of memory, use at your own peril.
• Added -X option to emit the directory tree in XML format (turns colorization off always.)
• Added --timefmt option to specify the format of time display (implies -D). Uses the strftime format.

Version 1.5.3

• Properly quote directories for the system command when tree is re-launched using the -R option.
• Fixed possible indentation problem if dirs[*] is not properly zeroed (Martin Nagy).
• Use strcoll() instead of strcmp() to sort files based on locale if set.
• Change "const static" to "static const" to remove some compiler warnings for Solaris (Kamaraju Kusumanchi).
• Actually use TREE_CHARSET if it's defined.
• Automatically select UTF-8 charset if TREE_CHARSET is not set, and the locale is set to *UTF-8 (overridden with --charset option.)

Version 1.5.2.2

• Set locale before checking MB_CUR_MAX.
• Added HP-NonStop platform support (Craig McDaniel <craigmcd@gmail.com>)
• Fixed to support 32 bit UID/GIDs.
• Added Solaris build options to Makefile (edit and uncomment to use). Provided by Wang Quanhong

Version 1.5.2.1

• Added strverscmp.c file for os's without strverscmp. Source file is attributed to: Jean-Franois Bignolles <bignolle@ecoledoc.ibp.fr>
• Try different approach to MB_CUR_MAX problem.
• Changed the argument to printit() to be signed char to avoid warnings.

Version 1.5.2

• Added --filelimit X option to not descend directories that have more than X number of files in them.
• Added -v option for version sorting (also called natural sorting) ala ls.

Version 1.5.1.2

• Fixed compile issues related to MB_CUR_MAX on non-linux machines.
• Removed unnecessary features.h

Version 1.5.1.1

• Regression in HTML output, fixed formatting issues.

Version 1.5.1

• Remove extraneous / at end of user input directory names when using -f option (Zurd)
• List available charsets if --charset option is missing charset argument.
• Fixed --charset option processing bug.
• Fixed missing <br>'s when -i option used with -H.
• Added -h option for human readable output.
• Colorization bugfix for special files and directories (make tree behave as ls does)

Version 1.5.0

• Added -T option to change title and H1 header in HTML output.
• Added -r option to reverse alpha sort output, ala. 'ls -r'.
• '|' wildcard support added by David MacMahon <davidm@astron.Berkeley.EDU>.
• Remove extraneous '/' at the end of dirs and dir-symlinks in HTML output.
• Removed several possible overflow problems by dynamically allocating arrays in several places.
• Better support for Locales and printing utf-8 encoded characters in filenames (still hackish).
• Fixed -t to alphasort files with same time-stamps.
• Fixed encoding of filenames in HTML output, Kyosuke and others.
• Patches by Kyosuke Tokoro <NBG01720@nifty.ne.jp>:
  • Now, runs OS/2 systems.
    • Print the file attributes in 'adhrs' format for each file, instead of the protections in 'drwxrwxrwx' format, when running the tree on OS/2 with option -p.
  • Added --charset option, to specify which character set is used for output.
    • You can specify any IANA registered character set name. But I have tested only following character sets: Shift_JIS EUC-JP IBM850 UTF-8 ISO-8859-1 US-ASCII
    • Now, `-S' option is equal to `--charset=IBM437'.
    • When running on OS/2 systems, the default value of this option is according to current codepage. On the other systems, no default.
• Change font-weight to font-size in CSS .VERSION.
• Change version to standard major.minor.patch format.
• Switch from artistic license to GPLv2.

Version 1.4

• Added large file support under Linux.
• Fixed crashing on missing command line arguments.
• Fixed several memory leaks
• Added --dirsfirst option to list directories first.
• Fixed formatting error when unable to open directories.
• Fixed bug in parse_dir_colors().
• Changed -I to also ignore directories.
• Added --nolinks command to turn off hyperlinks with the HTML output.
• Fixed several memory leaks in listdir().
• Some additional code cleanup in listdir().
• Some systems may define TRUE/FALSE, so don't create the enums for TRUE and FALSE if that's the case.
• Fixed over-allocation bug in read_dir().
• Added crude beginnings of color output for HTML via CSS (Ted Tiberio <ttiberio@rochester.rr.com>).
• Fixed buffer overflow problem in dircolors parsing.
• Fixed recursive symlink detection.
• Added --inodes and --device options.
• Added --noreport option.

Version 1.3

• Fixed long pathname problem by dynamically allocating the path.
• Added recursive symlink detection.
• Added --help and --version options.
• When -C is used and LS_COLORS is undefined, tree uses a default color scheme (thus -C always forces color output now).
• Added -S to show ASCII tree lines (Gerald Scheidl)
• Made tree more portable (Guido Socher and others) Following options curtsey of Francesc Rocher:
• Added -o <filename> to redirect the output.
• Added -H <baseHRef> to print the tree in HTML format.
• Added -L to set the maximum level of directories to print.
• Added -R to recursively restart the search at the level given by `-L' option (adding as well `-o 00Tree.html').

Version 1.2

• Added -D to print the date of the last modification.
• Added -t option to sort by last modification time (ala ls -t).
• Added -I <pattern>, simular to the -P option except tree does not print those files which match the pattern.
• Made tree print non-printable characters in filenames in standard unix carrot notation.
• Added -N option to make tree print filenames without any processing.
• Added -q option to make tree print non-printable characters in filenames as question marks.
• Added `|' to -F output and made it only print character type after the link on sym-links, not on the symlink name itself.
• Added -u option to display username/uid, and -g option to display group name/gid.
• Fully (pass the salt) implemented dircolors support.

Version 1.1

• Made some changes to the Makefile to insure proper installation and for multi-architecture support and a bug-fix.
• Made root directory colorized if dircolors is enabled.
• Put []'s around permission and size info, 'cause I think it looks better.
• Added -A option to enable ANSI-lines hack.
• Added some sanity checks for dircolors support.
• Added -P <pattern> to list only those files that match the wildcard given in <pattern>.
• Fixed error where relative symbolic links to directories would not be followed when the -l option was used.
• Made uid 0 the same as anyone else (-a was default for uid 0)
• Added -x directive to stay on one filesystem (ala find -xdev).

Version 1.0

• The original, a model of perfection...
