Author

Lists how many changes the author david has made where the file name ends with .scala

❯ ./commits.sh david ".scala$"

Changes for pattern ".scala$"
+2348, -1330, 1018 total (1.77:1 +/- ratio)

Also allows passing multiple patterns, where first argument is the author name and subsequent arguments are patterns to match against. Useful for comparing across languages, for example:

❯ ./commits.sh david ".scss$" ".js$" ".scala$"

Changes for pattern ".scss$"
+13743, -13703, 40 total (1.00:1 +/- ratio)

Changes for pattern ".js$"
+2969, -2567, 402 total (1.16:1 +/- ratio)

Changes for pattern ".scala$"
+2348, -1330, 1018 total (1.77:1 +/- ratio)
