You know, I think I was mistaken about the "bad things." Further
testing, ang grepping these prefs out of the server.prefs file:
Code:
--------------------
useUnifiedArtistsList: '1'
bandInArtists: ''
composerInArtists: ''
conductorInArtists: ''
--------------------
..yields these settings in the webUI:
27482
..so not being able to set a nil/undefined value via jsonrpc doesn't
seem to be an issue.
Here's my generic bash function for setting prefs this way:
Code:
--------------------
########################################################################
# slim_server_pref_set_json -- Set a server.pref via post to jsonrpc.js
########################################################################
slim_server_pref_set_json(){
local LPREF_VALUE="$1"
local LPREF="$(echo "$LPREF_VALUE" | sed -n -e 's#^\(.*\):.*#\1#p')"
local LVALUE="$(echo "$LPREF_VALUE" | sed -n -e "s#^${LPREF}:
\(.*\)\$#\1#p")"
local LARRAY=
if [ ! -z "$LPREF" ]; then
# Is the LVALUE an array, empty, ~ or need to be quoted?
if [ $(echo "$LVALUE" | grep -c '",') -gt 0 ]; then
LVALUE="[${LVALUE}]"
elif [ -z "$LVALUE" ]; then
LVALUE="\"\""
elif [ ${LVALUE:0:1} = "~" ]; then
LVALUE="\"\""
elif [ ${LVALUE:0:1} != "\"" ]; then
LVALUE="\"${LVALUE}\""
fi
JSONSTR="{\"id\":1,\"method\":\"slim.request\",\"params\":[\"\",[\"pref\",\"${LPREF}\",${LVALUE}]]}"
echo "Adding ${LPREF_VALUE} to server prefs."
curl --silent -H "Content-Type: application/json" -X POST -d
"$JSONSTR" http://localhost:9000/jsonrpc.js >/dev/null 2>&1
# Seems to be necessary so we don't slam the server with too
many requests to process..
sleep .25
fi
return 0
}
--------------------
Call with, e.g.:
Code:
--------------------
slim_server_pref_set_json "bandInArtists: ~"
--------------------
-- or, e.g. --
Code:
--------------------
slim_server_pref_set_json 'itemsPerPage: 500'
--------------------
..or for arrays:
Code:
--------------------
slim_server_pref_set_json 'mediadirs:
"/mnt/Media/Dir1","/mnt/Media/Dir1","/mnt/Media/Dir3"'
