This is companion code to my blog posts “Clojure as a dependency” and “Making of ‘Clojure as a dependency’”.
Data are downloaded using the GitHub API. You’ll need a personal access token to authenticate (you’ll be hitting GitHub’s rate limits otherwise).
Go to GitHub Settings → Personal Access Tokens and click “Generate new token”. Enter some meaningful name and select public_repo as a scope. Click “Generate token”.
You’ll be shown an alphanumeric sequence. Create a $HOME/.secrets.edn with the following content (substitute the token with the one you’ve just generated):
{:github-api-token "YOUR_API_TOKEN_GOES_HERE"}If you wish to skip the download process, you can reuse my download cache. Just untar this tarball into your $HOME. You won’t need the GitHub token in this case.
Run a REPL (clj or from within your editor of choice). Then:
(require 'versions.analyze)
(in-ns 'versions.analyze)
(def result (main))This will download the data if you don’t have it cached already, generate data for the plot in the article (graph1.csv) and produce a graph of computations, some of which are cited in the article. For example, to see how many repositories (actually project definition files) there are, grouped by type:
(:repos-count-by-deps-type result)
;=> {:leiningen 828, :cli-tools 140}To actually draw the plot, evaluate src/R/visualize.R in R. You will need ggplot2 (if you don’t have it, do install.packages('ggplot2') first).
