I haven't used Scintilla directly, but I've put together a small IDE using wxWindows - it's available as a wxStyledTextCtrl class. It's quite nice. So if you want to support wxWindows, you'll get it for free. > Would you consider Bach's addition of 'break' and 'watch' opcodes that > could communicate with outside programs to be a violation of the 'tracing' > clause of the source license? I has also suggested some time back that Robert add some sort of hooks for Euphoria's trace. I was thinking of something along the lines of a meta control of Euphoria: - Step ahead to the next instruction (etc.) - Run until next break - Return line X of the source code - Return the current line number of source code being executed So you could write a meta trace program in Euphoria itself; something like: procedure myTrace( sequence fileName ) integer theLineNumber sequence theLineText readFile( fileName ) while 1 if finished_running() then exit while end if run_until_break() while trace() -- display the line with the break theLineNumber = get_current_line_num() printf( 1, "At line %d: %s\n", { theLineNumber, get_source_text( theLineNumber ) ) -- display information about a value printf( 1, "the variable b = %s\n", get_variable_value( "b" ) ); end while end while end procedure It's a crummy example, but it should give the general flavor of the thing. Obviously, with this much control, it would be trivial for the user to get around the 300 line limit. -- David Cuny
