=====
Machine Learning, Statistics and Utilities around Developer Productivity
A few handy bits of functionality:
- Can checkout all repositories in Github
- Converts a tree of checked out repositories on disk into a pandas
dataframe
- Statistics on combined DataFrames
Installation
------------
::
pip install devml
This pip install installs a command-line tool: dml (which is referenced
in the documentation below). And also library devml, which is referenced
below as well.
Get environment setup
---------------------
Code is written to support Python 3.6 or greater. You can get that here:
https://www.python.org/downloads/release/python-360/.
An easy way to run the project locally is to check the repo out and in the root of the repo run:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
make setup
This create a virtualenv in ~/.devml
Next, source that virtualenv:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
source ~/.devml/bin/activate
Run Make All (installs, lints and tests)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
make all
# #Example output
#(.devml) ➜ devml git:(master) make all
#pip install -r requirements.txt
#Requirement already satisfied: pytest in /Users/noahgift/.devml/lib/python3.6/site-packages (from -r requirements.txt (line #1)
---------- coverage: platform darwin, python 3.6.2-final-0 -----------
Name Stmts Miss Cover
----------------------------------------------
devml/__init__.py 1 0 100%
devml/author_stats.py 6 6 0%
devml/fetch_repo.py 54 42 22%
devml/mkdata.py 84 21 75%
devml/org_stats.py 76 55 28%
devml/post_processing.py 50 35 30%
devml/state.py 29 9 69%
devml/stats.py 55 43 22%
devml/ts.py 29 14 52%
devml/util.py 12 4 67%
dml.py 111 66 41%
----------------------------------------------
TOTAL 507 295 42%
....
You don't use virtualenv or don't want to use it. No problem, just run
``make all`` it should probably work if you have python 3.6 installed.

make all
Explore Jupyter Notebooks on Github Organizations
-------------------------------------------------
You can explore combined datasets here using this example as a starter:

Expected Configuration
----------------------
The command-line tools expects for you to create a project directory
with a config.json file. Inside the config.json file, you will need to
provide an oath token. You can find information about how to do that
here:
https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/.
Alternately, you can pass these values in via the python API or via the
command-line as options. They stand for the following:
- org: Github Organization (To clone entire tree of repos)
- checkout\_dir: place to checkout
- oath: personal oath token generated from Github
::
➜ devml git:(master) ✗ cat project/config.json
{
"project" :
{
"org":"pallets",
"checkout_dir": "/tmp/checkout",
"oath": "<keygenerated from Github>"
}
}
Basic command-line Usage
------------------------
You can find out stats for a checkout or a directory full of checkout as
follows
.. code:: bash
dml gstats author --path ~/src/mycompanyrepo(s)
Top Commits By Author: author_name commits
0 John Smith 3059
1 Sally Joe 2995
2 Greg Mathews 2194
3 Jim Mayflower 1448
Basic API Usage (Converting a tree of repo(s) into a pandas DataFrame)
----------------------------------------------------------------------
::
In [1]: from devml import (mkdata, stats)
In [2]: org_df = mkdata.create_org_df(path=/src/mycompanyrepo(s)")
In [3]: author_counts = stats.author_commit_count(org_df)
In [4]: author_counts.head()
Out[4]:

Clone all repos in Github using API
-----------------------------------
::
In [1]: from devml import (mkdata, stats, state, fetch_repo)
In [2]: dest, token, org = state.get_project_metadata("../project/config.json")
In [3]: fetch_repo.clone_org_repos(token, org,
dest, branch="master")

FAQ
---
What is Churn and Why Do I Care?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Code churn is the amount of times a file has been modified. Relative
churn is the amount of times it has been modified relative to lines of
code. Research into defects in software has shown that relative code
churn is highly predictive of defects, i.e., the greater the relative
churn number the higher the amount of defects.
"Increase in relative code churn measures is accompanied by an increase
in system defect density; "
