Johnnydep

Pretty-print a dependency tree for a Python distribution. A simple example:

$ johnnydep requests
 name                           summary
────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
 requests                       Python HTTP for Humans.
 ├── certifi>=2023.5.7          Python package for providing Mozilla's CA Bundle.
 ├── charset_normalizer<4,>=2   The Real First Universal Charset Detector. Open, modern and actively maintained alternative to Chardet.
 ├── idna<4,>=2.5               Internationalized Domain Names in Applications (IDNA)
 └── urllib3<3,>=1.26           HTTP library with thread-safe connection pooling, file post, and more.

A more complex tree:

$ johnnydep boto3

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Johnnydep can also attempt to resolve the dependency tree:

$ johnnydep ipython --output-format pinned
ipython==9.13.0
decorator==5.3.1
ipython_pygments_lexers==1.1.1
jedi==0.20.0
matplotlib-inline==0.2.2
pexpect==4.9.0
prompt_toolkit==3.0.52
psutil==7.2.2
Pygments==2.20.0
stack-data==0.6.3
traitlets==5.15.0
parso==0.8.7
ptyprocess==0.7.0
wcwidth==0.7.0
asttokens==3.0.1
executing==2.2.1
pure_eval==0.2.3

Note that pip install lacked a working solver for many years, but pip v20.3 has a new solver (December 2020) which has really improved matters!
