483 | # TCL/EXPECT WART ALERT |
484 | # Expect does something very strange when it receives a single braced | |
485 | # argument. It splits it along word separators and performs substitutions. | |
486 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
487 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
488 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
489 | # "[ab]", because the backslashes will be removed by lindex. | |
490 | ||
491 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
492 | # that expect will do from within TCL. And many places make use of the | |
493 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
494 | # of the "[func]" construct, so we need to support that too. In order to | |
495 | # get this right we have to substitute quoted list elements differently | |
496 | # from braced list elements. | |
497 | ||
498 | # We do this roughly the same way that Expect does it. We have to use two | |
499 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
500 | # they'll be treated as command separators, and if we escape newlines | |
501 | # we mangle newlines inside of command blocks. This assumes that the | |
502 | # input doesn't contain a pattern which contains actual embedded newlines | |

1798 | ### Search the source file FILE, and return the line number of a line | |
1799 | ### containing TEXT. Use this function instead of hard-coding line | |
1800 | ### numbers into your test script. | |
1801 | ### | |
1802 | ### Specifically, this function uses GDB's "search" command to search | |
1803 | ### FILE for the first line containing TEXT, and returns its line | |
1804 | ### number. Thus, FILE must be a source file, compiled into the | |
1805 | ### executable you are running. If omitted, FILE defaults to the | |
1806 | ### value of the global variable `srcfile'; most test scripts set | |
1807 | ### `srcfile' appropriately at the top anyway. | |
1808 | ### | |
1809 | ### Use this function to keep your test scripts independent of the | |
1810 | ### exact line numbering of the source file. Don't write: | |
1811 | ### | |
1812 | ### send_gdb "break 20" | |
1813 | ### | |
1814 | ### This means that if anyone ever edits your test's source file, | |
1815 | ### your test could break. Instead, put a comment like this on the | |
1816 | ### source file line you want to break at: | |
1817 | ### | |
1818 | ### /* breakpoint spot: frotz.exp: test name */ | |
1819 | ### | |
1820 | ### and then write, in your test script (which we assume is named | |
1821 | ### frotz.exp): | |
1822 | ### | |
1823 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1824 | ### | |
1825 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1826 | ### Try this: | |
1827 | ### $ tclsh | |
1828 | ### % puts "foo [lindex "bar baz" 1]" | |
