ibquery

Query a running info-beamer pi using python

Uses the builtin query interface of info-beamer to get live data from a running instance.

Example: Getting generic information

import ibquery
ib = ibquery.InfoBeamerQuery() # connects to localhost by default
print "%s is running %s. current fps: %d, uptime: %dsec" % (ib.addr, ib.version, ib.fps, ib.uptime)

Example: Query info-beamer memory usage

import ibquery
ib = ibquery.InfoBeamerQuery()
print "The info-beamer process uses %dkb memory" % ib.resources.memory

Example: Query memory usage of each node

import ibquery
ib = ibquery.InfoBeamerQuery()
for path in ib.nodes:
    print "%s requires %dkb memory" % (path, ib.node(path).mem)

Example: Connect to a node

This requires a node that react to input events. See https://info-beamer.com/doc/info-beamer#node.event/input

import ibquery
ib = ibquery.InfoBeamerQuery()
s = ib.node('root').io(raw=True)
s.write('hello\n')
s.flush()
print s.readline()
