These are all my real commits from the last year.

## Installation
```sh
$ npm install -g git-stats
```

### Catching the `git commit` command
Would you like to catch and automatically store the commits when you do `git commit`? If so, try one of the following solutions.

#### Using `git` hooks
The way I recommend to track your git commits is to use git hooks. Run the following command to initialize the `post-commit` git hook.

```sh
# Using curl
curl -s https://raw.githubusercontent.com/IonicaBizau/git-stats/master/scripts/init-git-post-commit | bash

# ...or wget
wget -qO- https://raw.githubusercontent.com/IonicaBizau/git-stats/master/scripts/init-git-post-commit | bash
```

Then, you have to run `git init` into your existing git repositories from your local machine (that's because the `post-commit` should be updated). This
step will not be needed after cloning a repository (the git hooks will be added automatically from `~/.git-templates`).

#### Overriding the `git` command
One of the solutions is becoming a mad scientist, overriding the `git` command with a function. However, this may not work for you if you're using `zsh`.

Add the following lines in your `~/.bashrc` (or `~/.bash_profile` on OS X) file:

```sh
# Override the Git command
git() {
  cmd=$1
  shift
  extra=""

  quoted_args=""
  whitespace="[[:space:]]"
  for i in "$@"
  do
      quoted_args="$quoted_args \"$i\""
  done

  cmdToRun="`which git` "$cmd" $quoted_args"
  cmdToRun=`echo $cmdToRun | sed -e 's/^ *//' -e 's/ *$//'`
  bash -c "$cmdToRun"
  if [ $? -eq 0 ]; then
    # Commit stats
    if [ "$cmd" == "commit" ]; then
      commit_hash=`git rev-parse HEAD`
      repo_url=`git config --get remote.origin.url`
      commit_date=`git log -1 --format=%cd`
      commit_data="\"{ \"date\": \"$commit_date\", \"url\": \"$repo_url\", \"hash\": \"$commit_hash\" }\""
      git-stats --record "$commit_data"
    fi
  fi
}
```

## Usage

```sh
$ git-stats --help
git-stats --help
A GitHub-like contributions calendar, but locally, with all your git commits.

usage: git-stats [start] [end] [options] [data]

start:                    Optional start date
end:                      Optional end date

options:
  -v                      Displays version information.
  -h --help               Displays this help.
  --no-ansi               Doesn't use ANSI colors in the squares.
  --record <data>         Records a new commit. Don't use this unless you are
                          a mad scientist. If you are a developer, just use this
                          option as part of the module.
  --light                 Enable the light theme.

examples:
   git-stats # Displays your commit calendar
   git-stats -v
   git-stats -h
   git-stats --light # Light mode
   git-stats '1 January 2012' # All the commits from 1 January 2012, to now
   git-stats '1 January 2012' '31 December 2012' # All the commits from 2012

Your commit history is kept in the .git-stats, in your $HOME directory (~/)

Documentation can be found at https://github.com/IonicaBizau/git-stats
```

If you override the `git` command with a function, then your commits will be automatically recorded.

### Importing and deleting commits
I know it's not nice to start your git commit calendar from scratch. That's why I
created a `git-stats-importer` that imports or deletes the commits from a repository.

Check it out here: https://github.com/IonicaBizau/git-stats-importer

The usage is simple:

```sh
# Install the importer tool
$ npm install -g git-stats-importer

# Go to the repository you want to import
$ cd path/to/my-repository

# Import the commits
$ git-stats-importer

# ...or delete them if that's a dummy repository
$ git-stats-importer --delete
```

### Importing all the commits from GitHub and BitBucket
Yes, you read correctly! That's also possible. I [built a tool for that too](https://github.com/IonicaBizau/repository-downloader)!

```sh
# Download the repository downloader
$ git clone https://github.com/IonicaBizau/repository-downloader.git

# Go to repository downloader
$ cd repository-downloader

# Install the dependencies
$ npm install

# Start downloading and importing
$ ./start
```

### See the GitHub Contributions calendar
There is a solution for that, too! :smile: It's called [`ghcal`](https://github.com/IonicaBizau/ghcal).

```sh
# Install ghcal
$ npm install -g ghcal

# Checkout my contributions
$ ghcal ionicabizau
```
