541 | # TCL/EXPECT WART ALERT |
542 | # Expect does something very strange when it receives a single braced | |
543 | # argument. It splits it along word separators and performs substitutions. | |
544 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
545 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
546 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
547 | # "[ab]", because the backslashes will be removed by lindex. | |
548 | ||
549 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
550 | # that expect will do from within TCL. And many places make use of the | |
551 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
552 | # of the "[func]" construct, so we need to support that too. In order to | |
553 | # get this right we have to substitute quoted list elements differently | |
554 | # from braced list elements. | |
555 | ||
556 | # We do this roughly the same way that Expect does it. We have to use two | |
557 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
558 | # they'll be treated as command separators, and if we escape newlines | |
559 | # we mangle newlines inside of command blocks. This assumes that the | |

2271 | # This version is different: | |
2272 | # | |
2273 | # . It works with MI, and it also works when gdb is not running. | |
2274 | # | |
2275 | # . It operates on the build machine, not the host machine. | |
2276 | # | |
2277 | # . For now, this implementation fakes a current directory of | |
2278 | # $srcdir/$subdir to be compatible with the old implementation. | |
2279 | # This will go away eventually and some callers will need to | |
2280 | # be changed. | |
2281 | # | |
2282 | # . The TEXT argument is literal text and matches literally, | |
2283 | # not a regular expression as it was before. | |
2284 | # | |
2285 | # . State changes in gdb, such as changing the current file | |
2286 | # and setting $_, no longer happen. | |
