595 | # TCL/EXPECT WART ALERT |
596 | # Expect does something very strange when it receives a single braced | |
597 | # argument. It splits it along word separators and performs substitutions. | |
598 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
599 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
600 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
601 | # "[ab]", because the backslashes will be removed by lindex. | |
602 | ||
603 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
604 | # that expect will do from within TCL. And many places make use of the | |
605 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
606 | # of the "[func]" construct, so we need to support that too. In order to | |
607 | # get this right we have to substitute quoted list elements differently | |
608 | # from braced list elements. | |
609 | ||
610 | # We do this roughly the same way that Expect does it. We have to use two | |
611 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
612 | # they'll be treated as command separators, and if we escape newlines | |
613 | # we mangle newlines inside of command blocks. This assumes that the | |
