Welcome to Decker!

  Simple development tool that simplifies a pythonist's daily tasks.

Options:
  --version  Show the version and exit.
  --help     Show this message and exit.

Commands:
  format  Run code style format.

Format your code

  Run code style format.

Options:
  --exclude TEXT                  Files and directories that should be
                                  excluded on recursive searches.

  -l, --line-length INTEGER       How many characters per line to allow.
                                  [default: 79]

  -b, --backend [autoflake|docformatter|black|unify|isort]
                                  Specify formatting backends.
  --help                          Show this message and exit.

Formatting uses several tools, such as:

• autoflake to remove unusable variables and imports,
• docformatter to format docstrings,
• black to apply your coding style, format blocks, constants, among other things,
• unify to normalize quotes,
• And last but not least, isort to reorganize your imports.

To save and avoid many configurations, decker pre defines some things like:

Tool	Option	Pré defined	Description
autoflake	expand-star-imports	True	Expand wildcard star imports with undefined names
autoflake	in-place	True	Apply changes
autoflake	recursive	True	Recursive to defined sources
autoflake	remove-all-unused-imports	True	Remove all unused imports (not just those from the standard library)
autoflake	remove-unused-variables	True
docformatter	blank	False	Remove blank line after description
docformatter	in-place	True	Apply changes
docformatter	make-summary-multi-line	True	Add a newline before and after the summary of a one-line docstring
docformatter	pre-summary-newline	True	Add a newline before the summary of a multi-line docstring
docformatter	recursive	True	Recursive to defined sources
docformatter	wrap-summaries	79 (from decker global line-length setting)	Wrap long summary lines
black	line-length	79 (from decker global line-length setting)	How many characters per line to allow
black	skip-string-normalization	False	Skip string normalization to use unify to normalize
unify	in-place	True	Apply changes
unify	quote	"'" (Single quote)
unify	recursive	True	Recursive to defined sources
isort	atomic	True	Ensures the output doesn't save if the resulting file contains syntax errors
isort	case-sensitive	True	Tells isort to include casing when sorting module names
isort	combine-as	True	Combines as imports on the same line
isort	line-length	79 (from decker global line-length setting)	How many characters per line to allow
isort	lines-after-imports	2
isort	multi-line	3	Multi line output (0-grid, 1-vertical, 2-hanging, 3-vert-hanging, 4-vert-grid, 5-vert-grid-grouped, 6-vert-grid-grouped-no-comma).
isort	order-by-type	True	Order imports by type in addition to alphabetically
isort	remove-import	[__future__]	Removes the specified import from all files
isort	skip-glob	*venv*	Files that sort imports should skip over
isort	trailing-comma	True	Includes a trailing comma on multi line imports that include parentheses
isort	use-parentheses	True	Use parenthesis for line continuation on length limit instead of slashes

Note: Despite pre-defining all these settings, nothing is MANDATORY. All of these and any other configuration of these tools can be adjusted in pyproject.toml or in each configuration file of these tools.

The intention was to save time for those who already know and help those who do not already know.

Global Settings

To ensure ease and centralization of the other configurations, decker searches almost all of them in the pyproject.toml file, if any. Example:

[tool.autoflake]
expand-star-imports=false

[tool.black]
line-length=120
...

[tool.docformatter]
blank=false
...

[tool.unify]
quote='"'
...

[tool.isort]
line-length=120
trailing-comma=false
...

Decker settings on pyproject.toml

In addition, there are some that are global, where they are automatically passed on to all tools, such as:

[tool.decker]
line-length=79
exclude=same-package
verbose=1
sources=src/

Default sources (src/)

And to help as well, if the sources were not defined by the command line or pyproject.toml, decker looks for .py files in the directory in question and also for the src folder.

Extra

pdb++ & ipython

When installing decker, pdb++ and ipython are also installed to aid development.

Better print to pyproject.toml errors

Wraps and shows toml errors in a more "human" way, for example:

 + Unable to load pyproject.toml:
 |   
 |   [project]
 |   author='Douglas Farinelli'
 |   name='decker'
 |   repository='https://gitlab.com/douglasfarinelli/decker/'
 |   
 |   [tool.black]
 |   line-length=79
 |   skip-string-normalization=true
 |   target-version=
 |   
 + ^ Empty value is invalid
 |   
 |   ['py38']
 |   
 |   [tool.isort]
 |   atomic=true
 |   
 |   [tool.towncrier]
 |   package = 'crm'
 |   package_dir = 'src'
 |   filename = 'CHANGELOG.md'
 |   directory = 'changelog.d'

Next features

• [0.2.0] - Command decker check

A command to analyze various things in your code, such as type hints, pep8 and Code quality.

• [0.3.0] - Command decker release

Why not automate the flow VCS + bumpversion + towncrier? In other words, automate the generation of tags, changelog and auto-commit them.

Example:

decker release minor
