As part of my efforts to write an erlang plugin I did the following to
the bin/couchdb script:
1. Add the following near the head of the file:
PLUGINS_DIRECTORY=/usr/local/etc/couchdb/plugins
PLUGIN_INI_FILES=
PLUGIN_ERLANG_PATHS=
for plugin in $PLUGINS_DIRECTORY/*; do
if test -d $plugin/ebin; then
PLUGIN_ERLANG_PATHS="$PLUGIN_ERLANG_PATHS $plugin/ebin";
fi
if test -f $plugin/config.ini; then
PLUGIN_INI_FILES="$PLUGIN_INI_FILES $plugin/config.ini";
fi
done
2. Modify the code that accumulates the ini files:
if test -n "$INI_FILES"; then
ini_files="$PLUGIN_INI_FILES $INI_FILES"
else
ini_files="$DEFAULT_INI_FILE $LOCAL_INI_FILE $PLUGIN_INI_FILES"
fi
3. Modify the code that starts couchdb:
command="`/opt/local/bin/icu-config --invoke` \
/opt/local/bin/erl $interactive_option -smp auto -sasl
errlog_type error +K true \
-pa /usr/local/lib/couchdb/erlang/lib/couch-0.9.0a-incubating/
ebin \
/usr/local/lib/couchdb/erlang/lib/mochiweb-r82/ebin \
$PLUGIN_ERLANG_PATHS \
-eval \"application:load(inets)\" \
-eval \"application:load(crypto)\" \
-eval \"application:load(couch)\" \
-eval \"crypto:start()\" \
-eval \"inets:start()\" \
-eval \"couch_server:start([$start_arguments]), receive done -
> done end.\" "
Now I can drop components into /usr/local/etc/couchdb/plugins:
/usr/local/etc/plugins/
00test/
config.ini
ebin/
<blah>.beam
Something like this would seem to be the simplest possible mechanism
that allows separately packaged components.
