[Usage](#using-the-probe-module) + + [Example](#probe-module-example) +* [Dname module](#dname-module) + + [Usage](#using-the-dname-module) + + [Example](#dname-module-example) + +## Introduction + +If the shared `libknot.so` library isn't available in the library search path, it's +necessary to load the library first, e.g.: + +```python3 +import libknot +libknot.Knot("/usr/lib/libknot.so") +``` + +## Control module + +Using this module it's possible to create scripts for efficient tasks that +would require complex shell scripts with multiple calls of `knotc`. For +communication with the daemon it uses the same mechanism as the `knotc` utility, +i.e. communication via a Unix socket. + +The module API is stored in `libknot.control`. + +### Using the Control module + +The module usage consists of several steps: + +* Initialization and connection to the daemon control socket. +* One or more control operations. An operation is called by sending a command + with optional data to the daemon. The operation result has to be received + afterwards. +* Closing the connection and deinitialization. + +### Control module example + +```python3 +import json +import libknot.control + +# Initialization +ctl = libknot.control.KnotCtl() +ctl.connect("/var/run/knot/knot.sock") +ctl.set_timeout(60) + +try: + # Operation without parameters + ctl.send_block(cmd="conf-begin") + resp = ctl.receive_block() + + # Operation with parameters + ctl.send_block(cmd="conf-set", section="zone", item="domain", data="test") + resp = ctl.receive_block() + + ctl.send_block(cmd="conf-commit") + resp = ctl.receive_block() + + # Operation with a result displayed in JSON format + ctl.send_block(cmd="conf-read", section="zone", item="domain") + resp = ctl.receive_block() + print(json.dumps(resp, indent=4)) +except libknot.control.KnotCtlError as exc: + # Print libknot error + print(exc) +finally: + # Deinitialization + ctl.send(libknot.control.KnotCtlType.END) + ctl.close() +``` + +```python3 + # List configured zones (including catalog member ones) + ctl.send_block(cmd="conf-list", flags="z") + resp = ctl.receive_block() + for zone in resp['zone']: + print(zone) +``` + +## Probe module + +Using this module it's possible to receive traffic data from a running daemon with +active probe module. + +The module API is stored in `libknot.probe`. + +### Using the Probe module + +The module usage consists of several steps: + +* Initialization of one or more probe channels +* Periodical receiving of data units from the channels and data processing + +### Probe module example + +```python3 +import libknot.probe + +# Initialization of the first probe channel stored in `/run/knot` +probe = libknot.probe.KnotProbe("/run/knot", 1) + +# Array for storing up to 8 data units +data = libknot.probe.KnotProbeDataArray(8) +while (True): + # Receiving data units with timeout of 1000 ms + if probe.consume(data, 1000) > 0: + # Printing received data units in the default format + for item in data: + print(item) +``` + +## Dname module + +This module provides a few dname-related operations. + +### Using the Dname module + +The dname object is initialized from a string with textual dname. +Then the dname can be reformatted to wire format or back to textual format. + +### Dname module example + +```python3 +import libknot.dname + +dname = libknot.dname.KnotDname("e\\120ample.c\om.") +print(dname.size() +print(dname.str()) +print(dname.wire()) +``` + +```bash +13 +example.com. +b'\x07example\x03com\x00' +``` diff --git
