I wanted to know how many times we've changes a Release: tag in any of the package spec files under the LLVM umbrella over the course of the last 13 years.

Here's the script I ran:

projects="clang llvm lldb lld python-lit mlir libomp"

(for y in {2023..2010}; do 
     for p in $projects; do
          rows=$(git -C ~/dev/llvm-rpms/$p-fedora \
               log \
               --patch \
               --since $y-01-01 \
               --until $y-12-31 \
          -- $p.spec 2>&1\
          | grep -ioP "\+Release:\s*\K[0-9]+" \
          | sort \
          | uniq -c\
          | sort -nr \
          | tr " " ":")
          for r in $rows; do
               echo -n "$p|$y|"
               echo "$r" | grep -ioP "[0-9].*" | tr ":" "|"
          done
     done
done) | column \
    -s '|' \
    -t \
    --table-name "Release" \
    --table-columns "project,year,occurences,Release:-tag" \
    -R 3,4 \
    -o "  "

The output can be seen in output.txt below.

Any Release: tag with a 1 essentially means we've upgraded to another LLVM release.
