How do you guys normally handle the equivalent of ScriptAlias
directives in Apache? Can this be done with appmods and call_cgi
perhaps?

Okay, I'll try a more specific question. Has anyone gotten GNU
Mailman (list manager) to run under Yaws? On my Debian system, MM
installed the cgi progs in /usr/lib/cgi-bin/mailman/. In this
directory are a number of compiled C executables, with names like
'listinfo', 'subscribe', 'admin', etc. They don't have suffixes like
".cgi" and never will because the code expects them to be named as
they are. How do I tell Yaws that these files are to be executed as
cgi?

What kind of symlinks? I did try ln -s /usr/lib/cgi-bin/mailman
/www/root/lists, so that I could access http://site.com/lists/foo, but
still foo is not processed as a cgi.
Is there no way in Yaws to say "this file is a CGI, so execute it",
even if it doesn't end in .cgi, ,php, or .yaws?

There is a configuration option for Mailman to have extensions on these
files. Works for me.

Something like that could also be cooked up. I even have a situation in
which I call cgis that live at a completely differnent place and I
postprocess their output.

That's sort of a kludgey hack though, isn't it? I'd rather not resort
to that unless it's a last option.

Yes, except that users expect the URLs to not have extensions on them.
They have subscription notices saved with paths that I'd rather not
break. Of course I could do extensions and then rewrites from the old
URLs, but why should I have to?

Keep in mind that I'm still very new to Yaws, but it seems like there
should be an appmods solution to mimic what ScriptAlias does. Like in
my case, I might have in my yaws.conf:
appmods = </lists , scriptalias>
And then scriptalias.erl would possibly be able to mark the files in
/usr/lib/cgi-bin/mailman/* as cgi programs. Then when a users
requests http://site.com/lists/listinfo, things are handled correctly.
I do see mention of a "call_cgi" in the yaws_api man page:
call_cgi(Arg, Scriptfilename)
Calls an executable CGI script, given by its full path. Used to
make `.yaws' wrappers for CGI programs. This function usually
returns streamcontent.
Though it's not clear to me how exactly this can/should be used.

I attach an old appmod that I have found on my hard drive. Iirc, I used
it even before cgi support was fully integrated into yaws. I do not
know if it works with a current version of yaws, you will have to use it
as an example.
It implements a directory in which everything with a certain extension
(which can be empty) is called as a cgi script. It is configured via
variables in yaws.conf, these are `cgidir' and `cgiext'.

Is the example sufficiently clear?

Yeah, I see that, but perhaps Yaws could borrow this idea/code in
order to support alias/scriptalias.

Not completely no, but that's only becauase I'm stilll learning
Erlang. Before I saw this message I had written a simple module to
attempt to handle Mailman's cgi-bin programs.
In yaws.conf:
appmods = </lists, mailman>
Which I expect to handle URLs like:
http://site.com/lists/listinfo
http://site.com/lists/listinfo/foobar-dev
http://site.com/lists/options/foobar-dev/calmasy%40gmail.com
etc..
Only the first part of the path after 'lists' is the cgi-bin
executable. In the above cases, 'listinfo' is
/usr/lib/cgi-bin/mailman/listinfo and 'options' is
/usr/lib/cgi-bin/mailman/options. The parts of the URL following
those are just arguments to the CGI I guess (sorry, not that familiar
with how CGI works).
So I wrote a simple mailman.erl:
-module(mailman).
-include("../include/yaws_api.hrl").
-compile(export_all).
out(Arg) ->
Req = Arg#arg.req,
{abs_path, Path} = Req#http_request.path,
Script = Arg#arg.appmoddata,
yaws_cgi:call_cgi(Arg, "/usr/lib/cgi-bin/mailman/" ++ Script).
This correctly handles the first example URL above (lists/listinfo)
but not the others. I guess I'm not understanding how to pass
arguments to the CGI ('foobar-dev' and
'foobar-dev/calmasy%40gmail.com' in the above examples), because
doesn't call_cgi just accept Arg and the full path to the executable?
How do I pass on the remainer of the URL?

Ah, I know the feeling of learning several things at once :-)
The term for this argument is `pathinfo'.

If I am reading the source correctly, you want to call eg
yaws_cgi:call_cgi(Arg,
undefined,
"/usr/lib/cgi-bin/mailman/listinfo",
"/foobar-dev")
Since the easy example worked, this will hopefully also work, although I
am not sure if all variables will be set correctly.
Best,
Carsten

Thanks for your help. I rewrote mailman.erl as follows and it seems
to work! What does 'undefined' mean btw?
-include("../include/yaws_api.hrl").
-compile(export_all).
out(Arg) ->
Req = Arg#arg.req,
{abs_path, Path} = Req#http_request.path,
{Cgi, Cgiarg} = splitpath(Path),
case {Cgi, Cgiarg} of
{nocgi, nocgiarg} ->
{redirect_local, "/lists/listinfo"};
{Cgi, nocgiarg} ->
yaws_cgi:call_cgi(Arg,
undefined,
"/usr/lib/cgi-bin/mailman/" ++ Cgi);
{Cgi, Cgiarg} ->
yaws_cgi:call_cgi(Arg,
undefined,
"/usr/lib/cgi-bin/mailman/" ++ Cgi,
"/" ++ Cgiarg)
end.
splitpath(Path) ->
match(regexp:split(Path, "\/")).
match({ok, [[], _]}) ->
{nocgi, nocgiarg};
match({ok, [[], _, []]}) ->
{nocgi, nocgiarg};
match({ok, [[], _, Cgi]}) ->
{Cgi, nocgiarg};
match({ok, [[], _, Cgi, []]}) ->
{Cgi, nocgiarg};
match({ok, [[], _, Cgi, Cgiarg]}) ->
{Cgi, Cgiarg};
match({ok, [[], _, Cgi, Cgiarg, []]}) ->
{Cgi, Cgiarg};
match({ok, [[], _, Cgi|Cgiarg]}) ->
{Cgi, filename:join(Cgiarg)}.
