--from and --to arguments not working

[tomcreutz]

Hey,
I'm trying to extract (basically cut) a log file using following command:
pocolog sensor_kvh_1750_Logger.0.log --from 16:38:40.0 --to 17:08:45 --extract sensor_kvh_1750_cut.log --stream sensor_kvh_1750.calibrated_sensors

Unfortunately, I'm getting the following error:
It appears that the from and to functions are not implemented?

	6: from /usr/lib/ruby/2.5.0/optparse.rb:1523:in `order'

Yeah ... the pocolog CLI is very fragile.

You need to put the --stream first

Hey,
I tried this command:
pocolog sensor_kvh_1750_Logger.0.log --stream sensor_kvh_1750.calibrated_sensors --from 16:38:40.0 --to 17:08:45 --extract sensor_kvh_1750_cut.log

which, unfortunately again, results in an error:

Could you provide an example command?

[doudou]

Right. Sorry about that. The usage message is rather unclear.

pocolog --help

File convertion:
        --compress [OUTPUT]          compresses the log files into OUTPUT
        --to-new-format OUTPUT       converts the source file into the new format in OUTPUT
        --extract [OUTPUT]           creates a new log file with only the streams specified
                                     by the following --stream options
        --streams NAME[:start_index[:end_index]]
                                     specifies the stream names for --extract

--extract has to be first (before --stream) and --from and --to are not supported. You may provide sample indexes to --stream as specified in the usage message.
