Details
I am leveraging Cloc for the LOC, however, for the total, I am only counting the languages defined in config.json, so as to eliminate counting things like lines of JSON (of which, for example, the Kibana repo has a couple million!).
- Unfortunately GitHub API does not support sorting by size, and since the LOC counting logic requires locally cloning each of these giant repositories, I may be missing some. If I am, file an issue and I can add it to the list manually. Or, throw up a PR to have it added!
If you notice any errors with the above numbers, please file an issue and let me know! In particular the Cloc tool supports eliminating certain folders and files for LOC counts. With node, node_modules is excluded, however, for other languages I may be missing certain key configurations.
