441 | # TCL/EXPECT WART ALERT |
442 | # Expect does something very strange when it receives a single braced | |
443 | # argument. It splits it along word separators and performs substitutions. | |
444 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
445 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
446 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
447 | # "[ab]", because the backslashes will be removed by lindex. | |
448 | ||
449 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
450 | # that expect will do from within TCL. And many places make use of the | |
451 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
452 | # of the "[func]" construct, so we need to support that too. In order to | |
453 | # get this right we have to substitute quoted list elements differently | |
454 | # from braced list elements. | |
455 | ||
456 | # We do this roughly the same way that Expect does it. We have to use two | |
457 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
458 | # they'll be treated as command separators, and if we escape newlines | |
459 | # we mangle newlines inside of command blocks. This assumes that the | |

1768 | ### containing TEXT. Use this function instead of hard-coding line | |
1769 | ### numbers into your test script. | |
1770 | ### | |
1771 | ### Specifically, this function uses GDB's "search" command to search | |
1772 | ### FILE for the first line containing TEXT, and returns its line | |
1773 | ### number. Thus, FILE must be a source file, compiled into the | |
1774 | ### executable you are running. If omitted, FILE defaults to the | |
1775 | ### value of the global variable `srcfile'; most test scripts set | |
1776 | ### `srcfile' appropriately at the top anyway. | |
1777 | ### | |
1778 | ### Use this function to keep your test scripts independent of the | |
1779 | ### exact line numbering of the source file. Don't write: | |
1780 | ### | |
1781 | ### send_gdb "break 20" | |
1782 | ### | |
1783 | ### This means that if anyone ever edits your test's source file, | |
1784 | ### your test could break. Instead, put a comment like this on the | |
1785 | ### source file line you want to break at: | |
1786 | ### | |
1787 | ### /* breakpoint spot: frotz.exp: test name */ | |
1788 | ### | |
1789 | ### and then write, in your test script (which we assume is named | |
1790 | ### frotz.exp): | |
1791 | ### | |
1792 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1793 | ### | |
1794 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1795 | ### Try this: | |
1796 | ### $ tclsh | |
1797 | ### % puts "foo [lindex "bar baz" 1]" | |
