I wasn't aware of it. Anyway, I've downloaded and tested it. (installing was quite hard, it took me a while)
Heh, I could not make it run yet ;-)
it took a lot of guts and nerves ;)
What I always wanted is some kind of 'debug dumps'. E.g. the program I work on now sometimes prints graphs into stdout in some textual representation. To view them, I need to copy paste from the log, and run two external programs. If would be nice of log viewer could quickly locate such 'dumps' and show them using customizable command sequence, or maybe C++ code.
In case these debug dumps are logged into a file, and if I understood you correctly ;), then it's possible to do so with the LogViewer I created. I assume each such debug dump has a prefix (like, '[dbg]' or something) in order to differenciate it from something else. Just drag-and-drop your log file into Easy LogView. Assuming the prefix is '[dbg]'. Then, either locate one of such debug dump, and select the '[dbg]' word, right click and select "Existing Filter AND Containing Text..." or manually edit the filter, and add such a rule. That's all! Then, you'll only see these debug dumps. (of course, you can have as many filters as you wish, for your log file ;) )
If we return to libraries side, it's highly desirable for logging library to support data dumps. The primary difference with logging is that for each dumped object, you need to presicely identify the name of object being logged.
IOW, for two code lines:
log("lvk.flow") << "Entering some function"; dump("lvk.flow.paths.input") << graph;
I'm not sure what you mean. What's wrong with: log(whatever) << "lvk.flow.paths.input = " << graph;
The first output can be formatted in any possible way, but the second should include "lvk.flow.paths.input" somewhere, so that it's possible to automatically extract it from the log.
of course you can easily extract if from the log. Just use Easy LogViewer ;) Best, John
