Crawls rubygems dependencies graph

First, clone the repository:

git clone https://github.com/anvaka/allgems
cd ./allgems
npm install

Now you can crawl:

1. Index all gems into file: node index.js. This will use rubygems search api and download all packages into gems.json file. Most likely this will take ~2-3 hours. It is slow because the search API limits results to 30 per page.
2. Convert it to graph: node toGraph ./gems.json

Once the graph is ready you will have a graph.out file in the folder. Use it to run the layouter:

node layout.js ./graph.out

This will take around one hour and produce position files in the data folder. Finally you need to convert the positions into binary format, which can be understood by visualization:

node toBinary ./graph.out

This will produce two files:

• labels.json - records all package names in a flat array
• links.bin - records all graph connections in a binary format.

These two files and the last positions file (./data/100.pos) needs to be copied into the data folder of the visualization.
