## [route.py](route.py) & [logreader.py](logreader.py)
|
|
|
|
Route is a class for conviently accessing all the [logs](/selfdrive/loggerd/) from your routes. The LogReader class reads the non-video logs, i.e. rlog.bz2 and qlog.bz2. There's also a matching FrameReader class for reading the videos.
|
|
|
|
```python
|
|
from tools.lib.route import Route
|
|
from tools.lib.logreader import LogReader
|
|
|
|
r = Route("4cf7a6ad03080c90|2021-09-29--13-46-36")
|
|
|
|
# get a list of paths for the route's rlog files
|
|
print(r.log_paths())
|
|
|
|
# and road camera (fcamera.hevc) files
|
|
print(r.camera_paths())
|
|
|
|
# setup a LogReader to read the route's first rlog
|
|
lr = LogReader(r.log_paths()[0])
|
|
|
|
# print out all the messages in the log
|
|
import codecs
|
|
codecs.register_error("strict", codecs.backslashreplace_errors)
|
|
for msg in lr:
|
|
print(msg)
|
|
|
|
# setup a LogReader for the route's second qlog
|
|
lr = LogReader(r.log_paths()[1])
|
|
|
|
# print all the steering angles values from the log
|
|
for msg in lr:
|
|
if msg.which() == "carState":
|
|
print(msg.carState.steeringAngleDeg)
|
|
```
