Automate boring git tasks

# Python-Git

Automate the boring git stuff with python

## Motivation

Whenever I wanted to see the status of all my git repos I have to fire up the
`git-cmd.exe` shell on windows, navigate to each folder and then do a `git status`.
I have to do this both at home and at work.

But I got quickly tired of it. So I decided to make this tool to give me a quick
report so I can see what is ahead and what's behind and what's ahead at a glance.
In short, what needs attention so as to avoid those troubling merge conflicts.

## Requirements

Other thing you need is a computer with `git` either accessible from the command line (which means its in your system path) or as a standalone file somewhere in your system.
If you're working without installation rights, you can use a portable `git` and `python-git` will work just fine.

You can get a portable git version from [here](https://git-scm.com/download/win)

Just unzip it and place it somewhere on your disk. Later (during initialization), you'll need to tell `python-git` where this file is located.

## Installation

pip install python-git

## Setup

After installation, an initial setup is required to tell `pygit` the folders it needs to work with. Open a terminal and `python -m pygit` the below line with appropriate command line arguments.

The output of `python -m pygit --help` is shown below.

```cmd
usage: Pygit. Initialize working directories for python-git
[-h] [-v {0,1}] [-r RULES [RULES ...]] [-g GITPATH]
[-m MASTERDIRECTORY] [-s SIMPLEDIRECTORY [SIMPLEDIRECTORY ...]]

optional arguments:
-h, --help show this help message and exit
-v {0,1}, --verbosity {0,1}
turn verbosity ON/OFF
-r RULES [RULES ...], --rules RULES [RULES ...]
Set a list of string patterns for folders to skip
during setup
-g GITPATH, --gitPath GITPATH
Full pathname to git executable. cmd or bash.
-m MASTERDIRECTORY, --masterDirectory MASTERDIRECTORY
Full pathname to directory holding any number of git
repos.
-s SIMPLEDIRECTORY [SIMPLEDIRECTORY ...], --simpleDirectory SIMPLEDIRECTORY [SIMPLEDIRECTORY ...]
A list of full pathnames to any number of individual
git repos.
```

As an example you I have a folder in my `D:` drive that holds all my git repos, so I will setup `pygit` with the following command

python -m pygit --m D:\git -v 1

If it happens that you clone more repos into your master directory, you may update the index by issuing the `update()`command inside a `python` shell.

pygit.update()

## Usage

Activate python environment on command line.

import pygit

In case things change (perhaps you moved folders around or you add a new git repo) and you want to reset your folders just redo the initialization step

pygit.repos()

show all git repos in the format shown immediately below

pygit.load(repo_id_or_name) # load a repo

where `repo_id` is a string-valued id assigned to that particular repo. The first value in the `repos` command's output.

The `load(input_string)` command returns a `Commands` object for that repo, which provides a gateway for issuing git commands on the repository

Operations that can be performed on `Commands` object are shown below.

```python
r = pygit.load_repo(repo_id_or_name)
r.fetch() # perform fetch
r.status() # see status
r.add_all() # stage all changes for commit
r.commit(message='chore: minor changes') # commit changes. Press enter to accept default message
r.push() # perform push action
r.pull() # perform pull request
r.add_commit() # add and commit at once
```

### Batch Operations

The following batch operations on indexed repos are available.

pygit.load_multiple(*args) # load a set of repos
pygit.load_multiple("2", "5") # load only repo 2 and 5

returns a `generator` of `Commands` objects for repositories 2 and 5. Afterwards you can iterate over the repos like below

```python
for each in pygit.load_multiple("2", "5"):
each.add_commit()
```

pygit.all_status()

performs a `status` command on all indexed repos. The result is written to a markdown file.
Carries a timestamp of the time the command was issued. Call it a snapshot of your repo status if you will. Items which are out of sync with their remote counterpart are also highlighted as needing attention.

pygit.pull_all()

perform a `pull` request on all indexed repos at once. It returns `None`.

pygit.push_all()

performs a `push` action on all indexed repos at once. It returns `None`.

pygit.load_all()

returns a `generator` of `Commands` object for each indexed repo.

## To do

1. Add `git-bash.exe`
1. Implement `Commands.branch()`
1. Refactor tests
1. Auto-run test after importation to make sure every other thing works fine.
