Take Command 34.0:
Many performance and security optimizations.
Take Command is using a new version of the GUI framework.
Take Command has added Windows 11 light and dark themes.
Take Command has more dark mode support, including dark scrollbars when using a dark theme.
TCC:
Many performance and security optimizations.
TCC now supports wide Unicode characters (including surrogate pairs) everywhere.
TCC now maps executables that it finds in the PATH, to speed up finding them on subsequent execution. The map contains the .exe filename and the full path+name retrieved from the PATH search. The map is specific to each shell, and is not saved / restored when a shell exits and restarts. The MAPEXE command (see below) provides access to the mapped executables if you need to display / add / modify / delete entries. Executable mapping is invisible to the user, and it is unlikely that anyone other than administrators or advanced users will need to (or want to) use MAPEXE. If you have a short PATH, a fast SSD, no PATHEXT or executable extensions, and you aren't loading small executables repeatedly (i.e., in a loop) you probably won't perceive a significant performance difference.
TCC has an embedded SQLite 3.47.1 to support various internal commands, variables, and functions. This will be be used for new variables, functions, and commands in future versions.
If a filename begins with $ and ends with $, TCC will first look to see if the file exists. If not, TCC will remove the enclosing $'s and see if the file exists. If it does, TCC will convert it to a WSL path (like the @WSLPATH variable function, but easier to type). For example, if your current directory is d:\foo:
grep $myfile.dat$
will be translated to:
grep //mnt/d/foo/myfile.dat
You can enable / disable the filename translation with the WSLPath=YES|no directive in TCMD.INI.
All of the TCC file handling commands that support ranges (for example, DIR, PDIR, TREE, COPY, MOVE, etc.) now support fuzzy filename matching using Levenshtein Distances if the filename begins with two asterisks (**filename). The Levenshtein Distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other.
The default Levenshtein Distance is 3; you can change the default with the LVSDistance .INI directive (see below). You can specify the maximum distance to use with an individual command with a new command option:
/LVS=n
where n is the maximum distance to match. If you do not use the /LVS option, the maximum distance will default to 3. For example, if you have three files:
bubbles
babble
bobble
Then:
dir **babble
will return all three (babble has a distance of 0, bobble a distance of 1, and bubbles a distance of 2). But:
dir /lvs=1 **babble
will only return:
babble
bobble
You cannot combine fuzzy name matching with regular expressions or the * ? [...] wildcards.
The Oniguruma regular expression library has been updated to version 6.9.10. This includes support for Unicode 16.0, and the *SKIP control verb.
IDE / Batch Debugger:
Many performance and security optimizations.
The IDE is using a new version of the GUI framework.
The Scintilla edit control has been updated to version 5.5.4.
The Lexilla syntax coloring control has been updated to version 5.4.2.
The "Save to HTML" option now saves the font name, point size, and foreground + background colors (including the syntax coloring).
TCEDIT:
Many performance and security optimizations.
TCEdit is using a new version of the GUI framework.
The Scintilla edit control has been updated to version 5.5.4.
The Lexilla syntax coloring control has been updated to version 5.4.2.
The "Save to HTML" option now saves the font name, point size, and foreground + background colors (including the syntax coloring).
Help:
The help system is using a new theme and a new (much faster) HTML / CSS rendering engine.
New TCMD.INI Directives:
CDSpell=n - Autocorrects CD & CDD directory name misspellings. If the specified directory name is not found (and doesn't contain wildcards), TCC will look for a match with a transposed character, a missing character, or an extra character. If the total number of transposed / missing / extra characters is <= n, TCC will display the matching directory name and switch to that directory. You can set the CDSpell directive in the OPTION command on the "Command Line" page.
LVSDistance=n - Set the maximum Levenshtein Difference (aka edit distance) for fuzzy filename matching. The default value is 3.
New Internal Variables:
_bttime - Date/time of last BTMONITOR event
_eventtime - Date/time of last EVENTMONITOR event
_firewiretime - Date/time of last FIREWIREMONITOR event
_nettime - Date/time of last NETMONITOR event
_outputdebugtime - Date/time of last DEBUGMONITOR event
_powertime - Date/time of last POWERMONITOR event
_processtime - Date/time of last PROCESSMONITOR event
_servicetime - Date/time of the last SERVICEMONITOR event
_sqlite - The version of SQLite included in TCC (for example, 3.47.1).
_usbtime - Date/time of the last USBMONITOR event
Updated Variable Functions:
@BPEEK - added an optional fourth parameter +, which indicates that the value to read is a signed number.
@BPOKE - added an optional fourth parameter +, which indicates that value is a signed number.
@EMAIL - added support for upper case & mixed case.
@PID[name,+] - Is much faster if you aren't using wildcards or paths in the file name.
New Variable Functions:
@DLLTYPE[dllname] - like @EXETYPE, but returns the type of a DLL.

Updated Commands:
Added the CENTER option to the command dialog.
/Pn - the /P(ause) option has an optional argument n that specifies the number of seconds to wait for a keystroke before continuing.
If the CDSpell directive is set in TCMD.INI, TCC will autocorrect CD & CDD directory name misspellings. If the specified directory name is not found (and doesn't contain wildcards), TCC will look for a match (on the last pathname component only) with a transposed character, a missing character, or an extra character. If the total number of transposed / missing / extra characters is <= n, TCC will display the matching directory name and switch to that directory.
You can set the CDSpell directive in the OPTION dialog on the "Command Line" page.
Added a command dialog for CLS.
Added support for the COLOR / CMD.EXE hex color specification:
CLS bf
In this syntax, b is a hexadecimal digit that specifies the background color and f is a hexadecimal digit that specifies the foreground color.
Added a command dialog for COLOR.
/A - change the text color of the entire console buffer
/32 - show a » before 32-bit module names (EXE's and DLL's). Only supported with the default single column & full info display (i.e., no /B, /W, /2, etc.).
Changed to more closely follow the Linux behavior. When you change directories, TCC will start at the root of the new directory and scan to the subdirectory looking for .envtc files. So if you have .envtc files in one or more of the parent directories, they will be processed as well as any .envtc in the new directory. (The priority is top-down, so you can specify variables to be removed that were defined in a parent directory.)
/E"regex" - only display lines that match the regular expression, or if combined with /R, only save lines to the directory history that match the regular expression. /E"..." has been added to the DIRHISTORY command dialog.
/Tn has been added to the DIRHISTORY command dialog.
Added a command dialog for DIRS.
FSEARCH will read from STDIN (i.e., usually a pipe) if you don't specify path / filename. For example:
dir /s | fsearch /t"file47"
Added support for searching the CLIPn: and TMPn: pseudo-devices. For example:
dir /s | tmp5:
fsearch /t"file47" tmp5:
The optional subroutine filename now supports home directories, directory aliases, shell folders, extended parent directories ("..."), URLs, and UNCs.

New Commands:
TCC now saves a map in memory of executables that it finds in the PATH, to speed up finding them on subsequent calls. The map contains the .exe filename and the full path+name retrieved from the PATH search. The map is specific to each shell, and is not saved / restored when a shell exits and restarts. The MAPEXE command provides access to the mapped executables if you need to display / add / modify / delete entries. This command is not necessary for normal use; it is intended for advanced users and administrators.
The syntax is:
MAPEXE [/Pn /A /D /F] command [pathname]
/Pn - Pause after displaying a page. The /P option has an optional argument n that specifies the number of seconds to wait for a keystroke before continuing.
/A - Add the command and its full path+name to the map. The command must have an .EXE extension.
/D - Delete the command from the map. You can use wildcards in command.
/F - Find and display the full path+name saved in the map for the specified command. You can use wildcards in command.
The MAPEXE options are mutually exclusive; you can only specify one of them on the MAPEXE command line.
If you don't specify any arguments (except /P), MAPEXE will display all of the mapped executables. That display and the /F option will show the number of times the executable has been retrieved from the map,
