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.
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.
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

1783 ### Search the source file FILE, and return the line number of a line

1785 ### numbers into your test script.
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.
1794 ### Use this function to keep your test scripts independent of the
1795 ### exact line numbering of the source file. Don't write:
1797 ### send_gdb "break 20"
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:
1803 ### /* breakpoint spot: frotz.exp: test name */
1805 ### and then write, in your test script (which we assume is named
1808 ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
1810 ### (Yes, Tcl knows how to handle the nested quotes and brackets.
