Thanks to Roland0 and Paul, I've been testing with sexpect and JSON.awk
and it's working fairly well for detecting a "newsong" event and
retrieving json playlist info. The operation of sexpect is pretty
confusing. Seems like there should be a way to clear the buffer after a
match and a way to keep spawned processes from spewing all over stdout
but it's probably operator error.
Code:
--------------------
#!/bin/sh
sexpect -s 9090.sock spawn telnet 192.168.1.201 9090 &
sleep .5
sexpect -s 9090.sock send -enter "b8%3A27%3Aeb%3A94%3Aae%3A63 subscribe
playlist"
while :
do
sexpect -s 9090.sock expect -re "newsong"
sexpect -s 9090.sock expect -re ".*"
sexpect -s 9000.sock spawn nc 192.168.1.201 9000 &
sleep .1
sexpect -s 9000.sock send -f test
sexpect -s 9000.sock expect -timeout 10 -glob '{"params":*'
title=$(sexpect -s 9000.sock expect_out -index 0 | awk -f
/usr/local/bin/JSON.awk - | grep -m 1 '0,"title"' | cut -f2 | cut -d '"' -f2)
artist=$(sexpect -s 9000.sock expect_out -index 0 | awk -f
/usr/local/bin/JSON.awk - | grep -m 1 '"artist"' | cut -f2 | cut -d '"' -f2)
album=$(sexpect -s 9000.sock expect_out -index 0 | awk -f
/usr/local/bin/JSON.awk - | grep -m 1 '"album"' | cut -f2 | cut -d '"' -f2)
station=$(sexpect -s 9000.sock expect_out -index 0 | awk -f
/usr/local/bin/JSON.awk - | grep -m 1 '"remote_title"' | cut -f2 | cut -d '"'
-f2)
sexpect -s 9000.sock close
pid=$(sexpect -s 9000.sock get -ppid)
kill $pid
echo "$title"
echo "$artist"
echo "$album"
echo "$station"
done
kill $pid
pid=$(sexpect -s 9090.sock get -ppid)
kill $pid
rm 9090.sock 9000.sock
