[Feature/Request] Generic GIT repository parser

[stramel]

This plugin is great and has me wishing the project that I am on is using GitHub instead of Stash. So I started thinking about how we could achieve this same functionality using just standard git commands.

Here is what I have come up with:

This command will return the stats for the specified author.

• Adding the --perl-regexp flag allows you to specify a perl regexp to the authors like so: mstramel|stramel or Michael Stramel|stramel|mstramel
• Adding the grep -v will remove the specified paths from the statistics
• Adding the --all flag allows you to grab commits from all branches

$ git log --author="mstramel|stramel" --perl-regexp --all --pretty=tformat: --numstat | \
grep -v docs | \
gawk '{ add += $1 ; subs += $2 ; loc += $1 - $2 } END \
{ printf "added lines: %s removed lines : %s total lines: %s\n",add,subs,loc }' -

To handle author inconsistencies, I created a author map if you will. You can find these inconsistencies by running:

$ git shortlog -se

• The key should be the proper name that will be used
• The value should be the regexp to match the authors too.

// .authors.json
{
  "Michael Stramel": "Michael Stramel|stramel|mstramel"
}

By iterating over each author you can run it through the git log command to generate all the statistics. Would love to see this functionality bundled into this project. Let me know your thoughts! :+1:
