BLACK PYTHON FORMATTER MANUAL
BLACK PYTHON FORMATTER CODE

ConclusionĪll of the formatters are doing a good job of formatting the code. The main difference to the Facebook setting is that the namedtuple is formatted differently, as we saw in previous examples like the parameter splitting.

Yapf with the Google and pep8 setting will format the code the same in this case. In our first example, we will just show a function call inside a model which is normally too long for a line and see how the auto formatters are restructuring the code here. For yapf, this is not possible that easy since there are different base configurations that I wanted to try. In all examples, I will run the default configuration for each tool. For the comparison of yapf, I will use the Facebook, Google and pep8 settings since the Chromium setting does not get that much usage (2 spaces indent is a reason for this). With this pre-commit hook, unformatted code will never be pushed from the development machine to the remote repository. You should also consider a tool like pre-commit or husky and lint-staged for an automatic pre-commit hook which works in every environment and which is easy to install. This mindset is also followed by prettier, a big JavaScript auto formatter.Īll of these tools can be found on PyPi and be installed via pip or similar Python package managers and can be used on the command line which makes them cross-environment friendly. It has around 3800 stars on GitHub (June 2018) and the main incentive is to not have that many options so you do not even have to discuss the options. The tool is used by different open source libraries like Fabric 2 and pytest. It is an initiative of Łukasz Langa who is a Python Core Developer. The last popular auto formatter which is considered in this blog article. The tool also offers an online version where you can try out the formatting. More information can be found in the Knobs section of the README. You can also change a lot of style rules. It includes defaults for pep8, Google, Facebook, and Chromium styling. Other than that yapf is configurable in a lot of ways.

This requires manual work then to make the code look nice which wastes developer time. It will not make code compliant with pep guidelines or try to fix linting issues. It has ~7200 stars (June 2018) on GitHub and follows a different mindset in comparison to autopep8. Yet another Python formatter is another tool that is produced and maintained by none other than Google. As of the time of writing the repository had around 2200 stars (June 2018). The tool will also do small additional checks. There is a list of features listed in the README of the repository on which pep guidelines are supported. It uses pycodestyle to analyze which parts of your code do not fit to the pep-guidelines and will try to fix them. It is maybe the most used right now since it is one of the oldest tools out there. It will save engineers time and company time because developers will be more productive.įor Python there are three solutions out there: autopep8 - GitHubĪutopep8 is an auto formatter built and open-sourced and made by several developers. Those reasons are really good arguments for using auto formatters. Fewer merge conflicts since the style will almost always be the same
