[9fans] acme programming questions

[Tim Newsham]

I've been trying my hand at some very simple acme programming
tasks and have some questions.  I'm interested in a utility
that translate dot into a filename:line-line range and a
utility that waits for an acme window to be closed.  If I'm
reinventing these, I'd love to hear about existing programs
that do these.

I wrote a small tool to translate dot into filename:address
and in the process noticed that its relatively easy to
get the dot positions in terms of characters, but I couldn't
find a good way to translate those into line numbers without
manually processing the input file and counting newlines.
Is there a better way to do this?  If I had a tool to do
the translation I could do the rest of the process in rc.
As it stands I ended up doing it all in C.

I wrote a small tool to wait for a window to be closed by
reading the event file and copying back all events that
had the ``1'' bit set in the flag.  This allows many of the
events to occur, but none of the search features work.  Can I
have acme's default search behavior by feeding back more
events to acme?

In plan9port there is a libacme and <acme.h>
which makes some of this easier.  It is basically
a wrapping of the routines from acme Mail.
Using libacme, your event waiter can do
something like this to send the events back:

        while(winreadevent(w, e) > 0) {
                switch(e->c1){
                default:
                Unknown:
                        print("unknown message %c%c\n", e->c1, e->c2);
                        break;

                case 'E':       /* write to body; can't affect us */
                case 'F':       /* generated by our actions; ignore */
                case 'K':       /* type away; we don't care */
                        break;

                case 'M':
                        switch(e->c2){
                        case 'x':
                        case 'X':
                        case 'l':
                        case 'L':
                                /* send it back */
                                winwriteevent(w, e);
                                break;

                        case 'I':       /* modify away; we don't care */
                        case 'D':
                        case 'd':
                        case 'i':
                                break;

                        default:
                                goto Unknown;
                        }
                }
        }

I think Edit = is what you want.

more or less, except I want a program that I can manipulate the
output of.  If I make a program force an "Edit =" in a particular
window, the output will go to the error window (and possibly create
a new window)... am I overlooking something?
