How about this ? Otherwise, most parsers seem to be C/C++, where you’d have to translate. |

You’ll have to follow a multi-pass process. As it shows in the readme file for the repository, you can print all the topics in the bagfile. Once you know the topics, you can extend your program to grab the topics of interest. Or write a picker where you list the available topics, and pick from those topics to view more details. Only you know what information you want to pull out of the bagfile; if there is no “standard” to help you identify the information you want, then you’re going to have to use your own judgement. |
