1477 | ### gdb_get_line_number TEXT [FILE] | |
1478 | ### | |
1479 | ### Search the source file FILE, and return the line number of a line | |
1480 | ### containing TEXT. Use this function instead of hard-coding line | |
1481 | ### numbers into your test script. | |
1482 | ### | |
1483 | ### Specifically, this function uses GDB's "search" command to search | |
1484 | ### FILE for the first line containing TEXT, and returns its line | |
1485 | ### number. Thus, FILE must be a source file, compiled into the | |
1486 | ### executable you are running. If omitted, FILE defaults to the | |
1487 | ### value of the global variable `srcfile'; most test scripts set | |
1488 | ### `srcfile' appropriately at the top anyway. | |
1489 | ### | |
1490 | ### Use this function to keep your test scripts independent of the | |
1491 | ### exact line numbering of the source file. Don't write: | |
1492 | ### | |
1493 | ### send_gdb "break 20" | |
1494 | ### | |
1495 | ### This means that if anyone ever edits your test's source file, | |
1496 | ### your test could break. Instead, put a comment like this on the | |
1497 | ### source file line you want to break at: | |
1498 | ### | |
1499 | ### /* breakpoint spot: frotz.exp: test name */ | |
1500 | ### | |
1501 | ### and then write, in your test script (which we assume is named | |
1502 | ### frotz.exp): | |
1503 | ### | |
1504 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1505 | ### | |
1506 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1507 | ### Try this: | |
1508 | ### $ tclsh | |
1509 | ### % puts "foo [lindex "bar baz" 1]" | |
1510 | ### foo baz | |
1511 | ### % | |
1512 | ### Tcl is quite clever, for a little stringy language.) | |
