457 | # TCL/EXPECT WART ALERT |
458 | # Expect does something very strange when it receives a single braced | |
459 | # argument. It splits it along word separators and performs substitutions. | |
460 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
461 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
462 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
463 | # "[ab]", because the backslashes will be removed by lindex. | |
464 | ||
465 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
466 | # that expect will do from within TCL. And many places make use of the | |
467 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
468 | # of the "[func]" construct, so we need to support that too. In order to | |
469 | # get this right we have to substitute quoted list elements differently | |
470 | # from braced list elements. | |
471 | ||
472 | # We do this roughly the same way that Expect does it. We have to use two | |
473 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
474 | # they'll be treated as command separators, and if we escape newlines | |
475 | # we mangle newlines inside of command blocks. This assumes that the | |
476 | # input doesn't contain a pattern which contains actual embedded newlines | |
477 | # at this point! | |

1784 | ### containing TEXT. Use this function instead of hard-coding line | |
1785 | ### numbers into your test script. | |
1786 | ### | |
1787 | ### Specifically, this function uses GDB's "search" command to search | |
1788 | ### FILE for the first line containing TEXT, and returns its line | |
1789 | ### number. Thus, FILE must be a source file, compiled into the | |
1790 | ### executable you are running. If omitted, FILE defaults to the | |
1791 | ### value of the global variable `srcfile'; most test scripts set | |
1792 | ### `srcfile' appropriately at the top anyway. | |
1793 | ### | |
1794 | ### Use this function to keep your test scripts independent of the | |
1795 | ### exact line numbering of the source file. Don't write: | |
1796 | ### | |
1797 | ### send_gdb "break 20" | |
1798 | ### | |
1799 | ### This means that if anyone ever edits your test's source file, | |
1800 | ### your test could break. Instead, put a comment like this on the | |
1801 | ### source file line you want to break at: | |
1802 | ### | |
1803 | ### /* breakpoint spot: frotz.exp: test name */ | |
1804 | ### | |
1805 | ### and then write, in your test script (which we assume is named | |
1806 | ### frotz.exp): | |
1807 | ### | |
1808 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1809 | ### | |
1810 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1811 | ### Try this: | |
1812 | ### $ tclsh | |
1813 | ### % puts "foo [lindex "bar baz" 1]" | |
