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

2259 | # "$srcdir/$subdir". This is awkward, and can be fixed in the future, | |
2260 | # by changing the callers and the interface at the same time. | |
2261 | # In particular: gdb.base/break.exp, gdb.base/condbreak.exp, | |

2268 | # | |
2269 | # This means that if anyone ever edits your test's source file, | |
2270 | # your test could break. Instead, put a comment like this on the | |
2271 | # source file line you want to break at: | |
2272 | # | |
2273 | # /* breakpoint spot: frotz.exp: test name */ | |
2274 | # | |

2276 | # frotz.exp): | |
2277 | # | |
2278 | # send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |

2292 | # | |
2293 | # . It works with MI, and it also works when gdb is not running. | |
2294 | # | |
2295 | # . It operates on the build machine, not the host machine. | |
2296 | # | |
2297 | # . For now, this implementation fakes a current directory of | |
2298 | # $srcdir/$subdir to be compatible with the old implementation. | |
2299 | # This will go away eventually and some callers will need to | |
2300 | # be changed. | |

2303 | # not a regular expression as it was before. | |

2305 | # . State changes in gdb, such as changing the current file | |
2306 | # and setting $_, no longer happen. | |
