       Show HN: Codestat.dev - Stats from 2M open-source repositories
        
       Hi HN! This is a little site I put together while learning the Elm
       language as part of a hackathon at my work, I thought you might
       enjoy it.  Be sure to click the `(source)` buttons next to the
       graphs: you can edit them interactively & write your own queries
       against the entire data set. The syntax isn't well documented yet,
       but you can probably get the general idea pretty quickly based on
       the examples there.  If you like it, have questions, etc. let me
       know! If folks think this is cool, maybe I can get it turned into a
       legit project. :)

       | Details about the query syntax you can play with at
       | https://codestat.dev/explorer
       | 
       | Basic format is:                   content:output((REGEXP) -> $1)
       | 
       | For example, this query will find all `License: <word>` instances
       | in code/text files across all 2 million repos. It selects (`->
       | $1`) the first regexp capture group `(\w+)`:
       | content:output(License: (\w+)\n -> $1) count:all
       | 
       | There are some options you can add, like `count:all` (get all
       | results it can find, will timeout after 60s),
       | `repo:github\\.com/myorg/` (regexp filter to just your repos)
       | 
       | Can use this for code mining, too: to find out what the most
       | common delimiter passed to `strings.Split` in Go is, for example:
       | lang:go content:output(strings\.Split\(.*, (.*)\) -> $1)
       | count:all

       | Interesting! Why are the numbers/bar chart values bouncing
       | around? Is it making the same query from everyone's browser when
       | you load the page?

           | 
           | So the reason they bounce around is because new results are
           | streaming in, and it's updating the chart live based on
           | those.
           | 
           | After a little bit it will stop & have found all results
