# TCL/EXPECT WART ALERT
|
||
# Expect does something very strange when it receives a single braced
|
||
# argument. It splits it along word separators and performs substitutions.
|
||
# This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
|
||
# evaluated as "\[ab\]". But that's not how TCL normally works; inside a
|
||
# double-quoted list item, "\[ab\]" is just a long way of representing
|
||
# "[ab]", because the backslashes will be removed by lindex.
|
||
|
||
# Unfortunately, there appears to be no easy way to duplicate the splitting
|
||
# that expect will do from within TCL. And many places make use of the
|
||
# "\[0-9\]" construct, so we need to support that; and some places make use
|
||
# of the "[func]" construct, so we need to support that too. In order to
|
||
# get this right we have to substitute quoted list elements differently
|
||
# from braced list elements.
|
||
|
||
# We do this roughly the same way that Expect does it. We have to use two
|
||
# lists, because if we leave unquoted newlines in the argument to uplevel
|
||
# they'll be treated as command separators, and if we escape newlines
|
||
# we mangle newlines inside of command blocks. This assumes that the
|
||
# input doesn't contain a pattern which contains actual embedded newlines

|

# This will go away eventually and some callers will need to

# be changed.
