Johnnydep
=========
Pretty-print a dependency tree for a Python distribution. A simple example:
$ johnnydep requests
name summary
------------------------- ----------------------------------------------------------------------
requests Python HTTP for Humans.
├── certifi>=2017.4.17 Python package for providing Mozilla's CA Bundle.
├── chardet<3.1.0,>=3.0.2 Universal encoding detector for Python 2 and 3
├── idna<2.8,>=2.5 Internationalized Domain Names in Applications (IDNA)
└── urllib3<1.24,>=1.21.1 HTTP library with thread-safe connection pooling, file post, and more.
A more complex tree:
$ johnnydep boto3
name summary
--------------------------------------- -------------------------------------------------
boto3 The AWS SDK for Python
├── botocore<1.11.0,>=1.10.77 Low-level, data-driven core of boto 3.
│ ├── docutils>=0.10 Docutils -- Python Documentation Utilities
│ ├── jmespath<1.0.0,>=0.7.1 JSON Matching Expressions
│ └── python-dateutil<3.0.0,>=2.1 Extensions to the standard Python datetime module
│ └── six>=1.5 Python 2 and 3 compatibility utilities
├── jmespath<1.0.0,>=0.7.1 JSON Matching Expressions
└── s3transfer<0.2.0,>=0.1.10 An Amazon S3 Transfer Manager
└── botocore<2.0.0,>=1.3.0 Low-level, data-driven core of boto 3.
├── docutils>=0.10 Docutils -- Python Documentation Utilities
├── jmespath<1.0.0,>=0.7.1 JSON Matching Expressions
└── python-dateutil<3.0.0,>=2.1 Extensions to the standard Python datetime module
└── six>=1.5 Python 2 and 3 compatibility utilities
Johnnydep can also attempt to resolve the dependency tree:
$ johnnydep ipython --output-format pinned
ipython==6.5.0
appnope==0.1.0
backcall==0.1.0
decorator==4.3.0
jedi==0.12.1
pexpect==4.6.0
pickleshare==0.7.4
prompt-toolkit==1.0.15
pygments==2.2.0

traitlets==4.3.2
parso==0.3.1
ptyprocess==0.6.0
six==1.11.0
wcwidth==0.1.7
ipython-genutils==0.2.0
Note that [`pip install` lacked a working solver](https://github.com/pypa/pip/issues/988) for many years, but [pip v20.3 has a new solver](https://blog.python.org/2020/11/pip-20-3-release-new-resolver.html) (December 2020) which has really improved matters!
Check `johnnydep --help` for other features and options.
