Extract regressed crates from crater's `results.json`

crater-extract-regressed.sh

#!/bin/bash

set -euo pipefail

function find_crates {
  file=$1
  origin=$2
  result=$3

  case "$origin" in
    github)
      domain=https://github.com
      ;;
    cratesio)
      domain=https://crates.io
      ;;
    *)
      echo >2 "Unknown crate origin"
      exit 1
  esac

  jq -r ".crates[] | select(.res == \"$result\") | select(.url | startswith(\"$domain\")) | .url" "$file"
}

find_crates "$1" github regressed | sed -r 's|^https://github.com/([^/]+)/([^/]+)/.*$|\1/\2|'
find_crates "$1" cratesio regressed | sed -r 's|^https://crates.io/crates/([^/]+)/.*$|\1|'

Here's the sample output for this results.json.

You can pass a link to the generated text file to craterbot e.g. @craterbot run mode=check-only crates=http://some.site/crate-list.txt. This will create an experiment that runs only on those crates.
