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

| ### gdb_get_line_number TEXT [FILE] |
| ### |
| ### Search the source file FILE, and return the line number of a line |
| ### containing TEXT. Use this function instead of hard-coding line |
| ### numbers into your test script. |
| ### |
| ### Specifically, this function uses GDB's "search" command to search |
| ### FILE for the first line containing TEXT, and returns its line |
| ### number. Thus, FILE must be a source file, compiled into the |
| ### executable you are running. If omitted, FILE defaults to the |
| ### value of the global variable `srcfile'; most test scripts set |
| ### `srcfile' appropriately at the top anyway. |
| ### |
| ### Use this function to keep your test scripts independent of the |
| ### exact line numbering of the source file. Don't write: |
| ### |
| ### send_gdb "break 20" |
| ### |
| ### This means that if anyone ever edits your test's source file, |
| ### your test could break. Instead, put a comment like this on the |
| ### source file line you want to break at: |
| ### |
| ### /* breakpoint spot: frotz.exp: test name */ |
| ### |
| ### and then write, in your test script (which we assume is named |
| ### frotz.exp): |
| ### |
| ### send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n" |
| ### |
| ### (Yes, Tcl knows how to handle the nested quotes and brackets. |
| ### Try this: |
| ### $ tclsh |
| ### % puts "foo [lindex "bar baz" 1]" |
| ### foo baz |
| ### % |
| ### Tcl is quite clever, for a little stringy language.) |
