716 | # Expect does something very strange when it receives a single braced | |
717 | # argument. It splits it along word separators and performs substitutions. | |
718 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
719 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
720 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
721 | # "[ab]", because the backslashes will be removed by lindex. | |
722 | ||
723 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
724 | # that expect will do from within TCL. And many places make use of the | |
725 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
726 | # of the "[func]" construct, so we need to support that too. In order to | |
727 | # get this right we have to substitute quoted list elements differently | |
728 | # from braced list elements. | |
729 | ||
730 | # We do this roughly the same way that Expect does it. We have to use two | |
731 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
732 | # they'll be treated as command separators, and if we escape newlines | |
733 | # we mangle newlines inside of command blocks. This assumes that the | |

1757 | # underlined substring in | |

1845 | # b) We need two forms of the prompt: | |
1846 | # - a regexp to use in output matching, | |
1847 | # - a value to pass to the "set prompt" command. | |
1848 | # c) It's easier to convert the plain text form to its regexp form. | |
1849 | # | |
