To be able to compute the PageRank of the golang github repositories the following steps are needed:

1. Fetching the list of golang github repositories: lsrepo quesries the github api.
2. Downloading the source code from the repositories: fetcharchive downloads the archive of the repositories collected by lsrepo and extracts them without their stored dependencies (vendor folder).
3. Building up the module dependency graph and computing the repo starcount weighted pagrank modranker

To performe these steps one can run the following commands in the root of the repository: NOTE: a github api token is required.

REPOS_JSON="repos.json"
GH_TOKEN=GITHUB_API_TOKEN go run ./lsrepo/ ${REPOS_JSON} 2> ${REPOS_JSON}.log

DOWNLOAD_DIR=`pwd`"/repos/"
go run ./fetcharchive/ -rep ${REPOS_JSON} -d ${DOWNLOAD_DIR} 2> fetch_arch.log

DG="dg.json"
go run ./modranker/ -r ${REPOS_JSON} -o ${DG} -d repos/ > wrank.csv 2> wrank.log
