Absolutely. I've been planning to move to an CSS implementation 
for some time but my bandwidth for Wiki works is very limited at
the moment.

Yes, possibly if we can find a nice way to integrate it. I've been thinking
about a similar calendar plugin.   

If you write the code I'll check it in

Ok, looks ok, I'm also running embedded mode but don't
get OldGC to be undefined they way you do.
However, patch is ok and checked in.

RE: Embedded mode doesn't work in 1.51

I am mystified.

To start yaws in embedded mode, I use the following function:

start() ->
	application:start(yaws),
	GC = yaws_config:make_default_gconf(false),
	SC = #sconf{port = 8888,
			listen = {0,0,0,0},
			docroot = "www"},
	yaws_api:setconf(GC, [[SC]]).

Almost exactly as taken from the example. When yaws is started in embedded
mode the internal gconf thingy will be set to 'undefined' as far as I can
see from the code.

Are you starting yaws embedded in some new and fancy way I need to know or
... ?

Anyway, thanks for checking (in) my changes!

Michael

RE: compiling btt

I figured out my yaws+btt problem: yaws writes
stuff into /tmp/yaws so you can't have two uses
for yaws on the one machine. [Yaws even has
problems with -check if it can't write to /tmp/yaws
and that is something you don't expect].

Is there a simple solution or do I need to hack
the code. If the latter: any advice would be
appreciated.

And now for my next problem. After 'make local'
I try to start:

$ ~/bin/btt -i -c ~/btt.conf

ip = {127,0,0,1}
port = 8337
docroot = "/home/btt/btt_local_install/www"
dbdir = "/home/btt/btt_local_install/db"
maildir = "/home/btt/btt_local_install/mail"
logdir = "/home/btt/btt_local_install/logs/btt"
cmd = false
cmd_ip = {127,0,0,1}
cmd_port = 9338
Eshell V5.4.3  (abort with ^G)
1> {"init terminating in
do_boot",{{badmatch,{error,need_restart}},[{btt_yaws,configure_yaws,0},{
btt_yaws,start,0},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

Good detective work !!

This is a wellknown problem. Yaws has a flag "-I id" and a corresponding
config item "id" which address this.

So when running check from the makefiles for example, it's a good idea
to use the "id" feature 

as in the following extracts from a Makefile of mine:

YAWS=../../../yaws/bin/yaws
ID=check-${USER}
.SUFFIXES: .yaws-TS .yaws

%.yaws-TS: %.yaws
      r=`pwd`/../../../util/include; \
      $(YAWS)  \
        -I $(ID) -check $< $$r  || exit 1; \
        touch $<-TS

So, readup on the "id" flag in the manpages for "yaws" and "yaws.conf"
It is thus posible to run multiple yaws servers on the same box, but
they need to have different "id"s

The "id" is also used for the temorary filles under /tmp/yaws/*

The solution for btt is probably to use a special "id" for btt only, such
as "btt-"${USER}  or something. This would then have to be set in the
btt code which populates the configuration records for embedded mode.

If "btt" doesn't do this, i.e. use the default "id" which b.t.w is "default"
the btt interacts with other yaws instances (including check) on the
same machine.

To clear all old shit, first stop all yaws'es and then as root:

# rm -rf /tmp/yaws

Hmmm, this may be related to a crash (+ bugfix/patch) sent to the list
by Michael Arnoldus on Wed Feb  2 13:14:09 2005 
     (Ahhh I do like bugreports that accompanied with a patch !!!)

He also had similar problems with embedded mode on 1.51 and found some
weird stuff. His fix is in CVS. (or you can dig it up from the archives)

(I was puzzled by his embedded problems because I'm myself running
 embedded mode on 1.51. I never had the time to figure out 
 the real reason for his problems though, and since the fix was  good ...
 regardless, I took it)

Cheers

Re: 1.53

The new feature that makes it possible to do config changes
without stopping a running system (that was introduced in 
version 1.51), is it for embedded Yaws, or can it be done
for a standalone server as well?

Regards
Mikael
