395 | # TCL/EXPECT WART ALERT |
396 | # Expect does something very strange when it receives a single braced | |
397 | # argument. It splits it along word separators and performs substitutions. | |
398 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
399 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
400 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
401 | # "[ab]", because the backslashes will be removed by lindex. | |
402 | ||
403 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
404 | # that expect will do from within TCL. And many places make use of the | |
405 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
406 | # of the "[func]" construct, so we need to support that too. In order to | |
407 | # get this right we have to substitute quoted list elements differently | |
408 | # from braced list elements. | |
409 | ||
410 | # We do this roughly the same way that Expect does it. We have to use two | |
411 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
412 | # they'll be treated as command separators, and if we escape newlines | |
413 | # we mangle newlines inside of command blocks. This assumes that the | |

1659 | ### Search the source file FILE, and return the line number of a line | |
1660 | ### containing TEXT. Use this function instead of hard-coding line | |
1661 | ### numbers into your test script. | |
1662 | ### | |
1663 | ### Specifically, this function uses GDB's "search" command to search | |
1664 | ### FILE for the first line containing TEXT, and returns its line | |
1665 | ### number. Thus, FILE must be a source file, compiled into the | |
1666 | ### executable you are running. If omitted, FILE defaults to the | |
1667 | ### value of the global variable `srcfile'; most test scripts set | |
1668 | ### `srcfile' appropriately at the top anyway. | |
1669 | ### | |
1670 | ### Use this function to keep your test scripts independent of the | |
1671 | ### exact line numbering of the source file. Don't write: | |
1672 | ### | |
1673 | ### send_gdb "break 20" | |
1674 | ### | |
1675 | ### This means that if anyone ever edits your test's source file, | |
1676 | ### your test could break. Instead, put a comment like this on the | |
1677 | ### source file line you want to break at: | |
1678 | ### | |
1679 | ### /* breakpoint spot: frotz.exp: test name */ | |
1680 | ### | |
1681 | ### and then write, in your test script (which we assume is named | |
1682 | ### frotz.exp): | |
1683 | ### | |
1684 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1685 | ### | |
1686 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1687 | ### Try this: | |
1688 | ### $ tclsh | |
1689 | ### % puts "foo [lindex "bar baz" 1]" | |
