What is Wish 8.5.7 ?

I noticed a new application when right clicking on an item to open, I am given the option for Wish 8.5.7 or 8.4.19. I never installed this myself. Is this a new app with 10.6?

Thanks,

Ed

Wish is a simple windowing shell. I have absolutely no idea when it is used, nor why it exists. But perform a Spotlight search, Show All, and there it is.



Wish is a simple program consisting of the Tcl command language, the Tk
toolkit, and a main program that reads commands from standard input or
from a file. It creates a main window and then processes Tcl commands.
If wish is invoked with no arguments, or with a first argument that
starts with ``-'', then it reads Tcl commands interactively from stan-dard standard
dard input. It will continue processing commands until all windows
have been deleted or until end-of-file is reached on standard input.
If there exists a file .wishrc in the home directory of the user, wish
evaluates the file as a Tcl script just before reading the first com-mand command
mand from standard input.

If wish is invoked with an initial fileName argument, then fileName is
treated as the name of a script file. Wish will evaluate the script in
fileName (which presumably creates a user interface), then it will
respond to events until all windows have been deleted. Commands will
not be read from standard input. There is no automatic evaluation of
.wishrc when the name of a script file is presented on the wish command
line, but the script file can always source it if desired.


OPTIONS
Wish automatically processes all of the command-line options described
in the OPTIONS summary above. Any other command-line arguments besides
these are passed through to the application using the argc and argv
variables described later.


APPLICATION NAME AND CLASS
The name of the application, which is used for purposes such as send
commands, is taken from the -name option, if it is specified; other-wise otherwise
wise it is taken from fileName, if it is specified, or from the command
name by which wish was invoked. In the last two cases, if the name
contains a ``/'' character, then only the characters after the last
slash are used as the application name.

The class of the application, which is used for purposes such as speci-fying specifying
fying options with a RESOURCE_MANAGER property or .Xdefaults file, is
the same as its name except that the first letter is capitalized.


VARIABLES
Wish sets the following Tcl variables:

argc Contains a count of the number of arg arguments (0 if
none), not including the options described above.

argv Contains a Tcl list whose elements are the arg arguments
that follow a -- option or don't match any of the
options described in OPTIONS above, in order, or an
empty string if there are no such arguments.

argv0 Contains fileName if it was specified. Otherwise, con-tains contains
tains the name by which wish was invoked.

geometry If the -geometry option is specified, wish copies its
value into this variable. If the variable still exists
after fileName has been evaluated, wish uses the value
of the variable in a wm geometry command to set the main
window's geometry.

tcl_interactive
Contains 1 if wish is reading commands interactively
(fileName was not specified and standard input is a ter-minal-like terminal-like
minal-like device), 0 otherwise.


SCRIPT FILES
If you create a Tcl script in a file whose first line is
#!/usr/local/bin/wish
then you can invoke the script file directly from your shell if you
mark it as executable. This assumes that wish has been installed in
the default location in /usr/local/bin; if it's installed somewhere
else then you'll have to modify the above line to match. Many UNIX
systems do not allow the #! line to exceed about 30 characters in
length, so be sure that the wish executable can be accessed with a
short file name.

An even better approach is to start your script files with the follow-ing following
ing three lines:
#!/bin/sh
# the next line restarts using wish \
exec wish "$0" "$@"
This approach has three advantages over the approach in the previous
paragraph. First, the location of the wish binary doesn't have to be
hard-wired into the script: it can be anywhere in your shell search
path. Second, it gets around the 30-character file name limit in the
previous approach. Third, this approach will work even if wish is
itself a shell script (this is done on some systems in order to handle
multiple architectures or operating systems: the wish script selects
one of several binaries to run). The three lines cause both sh and
wish to process the script, but the exec is only executed by sh. sh
processes the script first; it treats the second line as a comment and
executes the third line. The exec statement cause the shell to stop
processing and instead to start up wish to reprocess the entire script.
When wish starts up, it treats all three lines as comments, since the
backslash at the end of the second line causes the third line to be
treated as part of the comment on the second line.

The end of a script file may be marked either by the physical end of |
the medium, or by the character, '\032' ('\u001a', control-Z). If this |
character is present in the file, the wish application will read text |
up to but not including the character. An application that requires |
this character in the file may encode it as ``\032'', ``\x1a'', or |
``\u001a''; or may generate it by use of commands such as format or |
binary.

PROMPTS
When wish is invoked interactively it normally prompts for each command
with ``% ''. You can change the prompt by setting the variables
tcl_prompt1 and tcl_prompt2. If variable tcl_prompt1 exists then it
must consist of a Tcl script to output a prompt; instead of outputting
a prompt wish will evaluate the script in tcl_prompt1. The variable
tcl_prompt2 is used in a similar way when a newline is typed but the
current command isn't yet complete; if tcl_prompt2 isn't set then no
prompt is output for incomplete commands.

Text Mate is a developer's tool that uses various unix scripting technologies such as Wish Shell.
I don't know if Text Mate specifically uses Wish Shell for anything, but it may write code into the
file headers in such a way that triggers the Wish Shell.app to respond and ask if it should open the
file for you.
Snow Leopard's Wish.app (Wish Shell.app) is located here:
/System/Library/Frameworks/Tk.framework/Versions/8.5/Resources/Wish.app
