1404 | ### gdb_get_line_number TEXT [FILE] | |
1405 | ### | |
1406 | ### Search the source file FILE, and return the line number of a line | |
1407 | ### containing TEXT. Use this function instead of hard-coding line | |
1408 | ### numbers into your test script. | |
1409 | ### | |
1410 | ### Specifically, this function uses GDB's "search" command to search | |
1411 | ### FILE for the first line containing TEXT, and returns its line | |
1412 | ### number. Thus, FILE must be a source file, compiled into the | |
1413 | ### executable you are running. If omitted, FILE defaults to the | |
1414 | ### value of the global variable `srcfile'; most test scripts set | |
1415 | ### `srcfile' appropriately at the top anyway. | |
1416 | ### | |
1417 | ### Use this function to keep your test scripts independent of the | |
1418 | ### exact line numbering of the source file. Don't write: | |
1419 | ### | |
1420 | ### send_gdb "break 20" | |
1421 | ### | |
1422 | ### This means that if anyone ever edits your test's source file, | |
1423 | ### your test could break. Instead, put a comment like this on the | |
1424 | ### source file line you want to break at: | |
1425 | ### | |
1426 | ### /* breakpoint spot: frotz.exp: test name */ | |
1427 | ### | |
1428 | ### and then write, in your test script (which we assume is named | |
1429 | ### frotz.exp): | |
1430 | ### | |
1431 | ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" | |
1432 | ### | |
1433 | ### (Yes, Tcl knows how to handle the nested quotes and brackets. | |
1434 | ### Try this: | |
1435 | ### $ tclsh | |
1436 | ### % puts "foo [lindex "bar baz" 1]" | |
