> `git-quick-stats` is a simple and efficient way to access various statistics in a git repository.
>
> Any git repository may contain tons of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because there are a gadzillion options to a gadzillion git commands – I don’t think there is a single person alive who knows them all. Probably not even [Linus Torvalds](https://github.com/torvalds) himself :).

### Git log since and until

You can set the variables `_GIT_SINCE` and/or `_GIT_UNTIL` before running `git-quick-stats` to limit the git log. These work similar to git's built-in `--since` and `--until` log options.

```bash
export _GIT_SINCE="2017-01-20"
export _GIT_UNTIL="2017-01-22"
```

Once set, run `git quick-stats` as normal. Note that this affects all stats that parse the git log history until unset.

### Git log limit

You can set variable `_GIT_LIMIT` for limited output. It will affect the "changelogs" and "branch tree" options.

```bash
export _GIT_LIMIT=20
```

### Git log options

You can set `_GIT_LOG_OPTIONS` for [git log options](https://git-scm.com/docs/git-log#_options):

```bash
export _GIT_LOG_OPTIONS="--ignore-all-space --ignore-blank-lines"
```

### Git pathspec

You can exclude a directory from the stats by using [pathspec](https://git-scm.com/docs/gitglossary#gitglossary-aiddefpathspecapathspec)

```bash
export _GIT_PATHSPEC=':!directory'
```

You can also exclude files from the stats. Note that it works with any alphanumeric, glob, or regex that git respects.

```bash
export _GIT_PATHSPEC=':!package-lock.json'
```

### Git merge view strategy

You can set the variable `_GIT_MERGE_VIEW` to enable merge commits to be part of the stats by setting `_GIT_MERGE_VIEW` to `enable`. You can also choose to only show merge commits by setting `_GIT_MERGE_VIEW` to `exclusive`. Default is to not show merge commits. These work similar to git's built-in `--merges` and `--no-merges` log options.

```bash
export _GIT_MERGE_VIEW="enable"
export _GIT_MERGE_VIEW="exclusive"
```

### Git branch

You can set the variable `_GIT_BRANCH` to set the branch of the stats. Works with commands `--git-stats-by-branch` and `--csv-output-by-branch`.

```bash
export _GIT_BRANCH="master"
```

### Color themes

You can change to the legacy color scheme by toggling the variable `_MENU_THEME` between `default` and `legacy`

```bash
export _MENU_THEME="legacy"
```

## FAQ

*Q:* I get some errors after run git-quick-stats in cygwin like `/usr/local/bin/git-quick-stats: line 2: $'\r': command not found`

*A:* You can run the dos2unix app in cygwin as follows: `/bin/dos2unix.exe /usr/local/bin/git-quick-stats`. This will convert the script from the CR-LF convention that Microsoft uses to the LF convention that UNIX, OS X, and Linux use. You should then should be able to run it as normal.

*Q:* How they could be used in a project with many git projects and statistics would show a summary of all git projects?

*A:* If you want to include submodule logs, you can try using the following: `export _GIT_LOG_OPTIONS="-p --submodule=log"`
(more info about [git log --submodule](https://git-scm.com/docs/git-log#Documentation/git-log.txt---submoduleltformatgt))

## Contribution

Want to contribute? Great! First, read this page.

### Code reviews

All submissions, including submissions by project members, require review.</br>
We use GitHub pull requests for this purpose.

### Some tips for good pull requests

* Use our code </br>
  When in doubt, try to stay true to the existing code of the project.
* Write a descriptive commit message. What problem are you solving and what
  are the consequences? Where and what did you test? Some good tips:
  [here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message)
  and [here](https://www.kernel.org/doc/Documentation/SubmittingPatches).
* If your PR consists of multiple commits which are successive improvements /
  fixes to your first commit, consider squashing them into a single commit
  (`git rebase -i`) such that your PR is a single commit on top of the current
  HEAD. This make reviewing the code so much easier, and our history more
  readable.

### Formatting

This documentation is written using standard [markdown syntax](https://help.github.com/articles/markdown-basics/). Please submit your changes using the same syntax.
