507 | # TCL/EXPECT WART ALERT |
508 | # Expect does something very strange when it receives a single braced | |
509 | # argument. It splits it along word separators and performs substitutions. | |
510 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
511 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
512 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
513 | # "[ab]", because the backslashes will be removed by lindex. | |
514 | ||
515 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
516 | # that expect will do from within TCL. And many places make use of the | |
517 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
518 | # of the "[func]" construct, so we need to support that too. In order to | |
519 | # get this right we have to substitute quoted list elements differently | |
520 | # from braced list elements. | |
521 | ||
522 | # We do this roughly the same way that Expect does it. We have to use two | |
523 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
524 | # they'll be treated as command separators, and if we escape newlines | |
525 | # we mangle newlines inside of command blocks. This assumes that the | |
526 | # input doesn't contain a pattern which contains actual embedded newlines | |
