# Github Path Downloader

A tool for downloading individual files/directories from Github or Github Enterprise.

This circumvents the requirement to clone a complete repository.

# Requirements:

- Python 3.4+
- A Github or Github Enterprise Account

# Installation:

pip:

```bash
$ pip install githubdl
```

http:

```bash
$ pip install git+https://github.com/wilvk/githubdl.git
```

ssh:

```bash
$ pip install git+ssh://git@github.com:wilvk/githubdl.git
```

from clone:

```bash
$ git clone git@github.com:wilvk/githubdl.git
$ cd githubdl
$ pip install -e .
```

# Usage:

## Obtaining a Github token:

You will need a token from either Github Enterprise or Github as this package works with the Github v3 API.

To do this:

- Log into your Github account
- Click the Avatar Menu in the top-right corner, and select `Settings`
- On the Settings page, from the menu on the left-hand side, select `Developer Settings`
- From the Developer Settings page, from the menu, select `Personal access tokens`
- Click the `Generate new token` button
- Enter a name for the token. The token should only require the `read:org` permission specified.

There are also instructions on how to do this [here](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/).

# Usage (from the commandline):

With your new Github token, export it as the environment variable `GIT_TOKEN`.

## On Unix/Linux:

```bash
$ export GIT_TOKEN=1234567890123456789012345678901234567890123
```

## On Windows:

```cmd
C:\> set GIT_TOKEN=1234567890123456789012345678901234567890123
```

## Single file:

Then, for example, to download a file called `README.md` from the repository `http://github.com/wilvk/pbec`:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -f "README.md"
2018-05-12 07:19:16,934 - root         - INFO     - Requesting file: README.md at url: https://api.github.com/repos/wilvk/pbec/contents/README.md
2018-05-12 07:19:18,165 - root         - INFO     - Writing to file: README.md
```

## Entire directory:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -d "support"
2018-05-12 07:19:41,667 - root         - INFO     - Retrieving a list of files for directory: support
2018-05-12 07:19:41,668 - root         - INFO     - Requesting file: support at url: https://api.github.com/repos/wilvk/pbec/contents/support
2018-05-12 07:19:42,978 - root         - INFO     - Requesting file: support/Screen Shot 2017-12-10 at 9.27.56 pm.png at url: https://api.github.com/repos/wilvk/pbec/contents/support/Screen Shot 2017-12-10 at 9.27.56 pm.png

2018-05-12 07:19:46,286 - root         - INFO     - Retrieving a list of files for directory: support/docker
...
```

## Entire repository:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -d "/" -t "."

...
```

Note: if `-t` is not set, output will go to your `/` directory.

## By commit hash:

## Single file from a specific commit:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -f "README.md" -r "c29eb5a5d364870a55c0c22f203f8c4e2ce1c638"

...
```

## Entire directory from a specific commit:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -d "support" -r "c29eb5a5d364870a55c0c22f203f8c4e2ce1c638"

...

```
## Entire repository from a specific commit:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -d "/" -r "c29eb5a5d364870a55c0c22f203f8c4e2ce1c638" -t "."

...
```

Note: if `-t` is not set, output will go to your `/` directory.

## Entire repository from a specific commit, with submodules (as specified in .gitmodules):

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -d "/" -r "c29eb5a5d364870a55c0c22f203f8c4e2ce1c638" -t "." -s

...
```

# List all tags for a repository in JSON:

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -a
```

```bash
$ githubdl -u "http://github.com/wilvk/pbec" -b
```
