[Tcllib-devel] Package request

[Andreas K. <andreask@ActiveState.com>]

I would like to point the people here to the RFE


https://sourceforge.net/tracker/index.php?func=detail&aid=1015402&group_id=1
2883&atid=362883

which is a for a package 'which', which (sic) is for searching the PATH.

I currently see no real need for it, because of the core 'auto_execok'.

There a differences however, if I read the documentation right:

*	auto_execok		returns a list, thus able to find and
	return commands requiring the cmd.com on Windows.

	which returns just the path, and is not able to find shell builtins.

*	which uses 'file executable' to check if a file is executable.
	I do not know if that is really cross-platform.

	On windows we can execute something which is not executable,
	simply through its association. Example:

	% auto_execok tkcon.tcl
	C:/Tcl/tdk31_109000/bin/tkcon.tcl
	% file executable [auto_execok tkcon.tcl]
	0
	%

	And I can still run 'tkcon.tcl' just so.


Any other comments regarding this RFE ?
