In simplest if we just want to format a file or a folder of files simple run the following command in terminal.
#Black python formatter install#
If you can't wait for the latest hotness and want to install from GitHub, use: If you want to format Jupyter Notebooks, install pip install black. Python 2 support needs the typed_ast dependency, which will be installed with pip install black.
#Black python formatter code#
Black does not have a lot of options to tinker with and has a lot of opinion on how your code should look and feel.īlack isn't for everyone and you may find something that is a dealbreaker for you personally, which is okay! The current Black code style is described here.īlack can be easily integrated with many editors such as Vim, Emacs, VSCode, Atom or a version control system like GIT.īlack requires Python 3.6.2+ to run but has a capability to format Python 2 code too. Unlike flake8 or pycodestyle rather then telling where the issue is and ask you to manually fix it Black not only report format errors but also fixes them. In python we have an automated package Black which helps in ensures code quality.īlack is known as the uncompromised Python code formatter.
Then change your f keybinding command to run this command after Black:Īutocmd FileType python nmap f :Black :IindentĪ down-side to this approach is that it adds an extra indentation change to history in-addition-to/after the formatter change, however the upside is that you keep using the maintained plugin and formatter.Writing well-formatted code is very important, breaking the actual programs in easy to understand small programs as compared to having a more complex program helps in better understanding of code and helps in maintaining code quality. To your vim config and running :UpdateRemotePlugins Touch ~/.vim/plugged/iindent/rplugin/python3/iindent.pyĪnd add to it the code above, then install with vimplug/your-plugin-manager by adding Plug '~/.vim/plugged/iindent' Mkdir -p ~/.vim/plugged/iindent/rplugin/python3 Make a directory for this new plugin in the plugged directory which is in your vim config directory: It uses and depends on pynvim, install it with pip pip install -user pynvim or better yet install it with your distro's package manager which upgrades it with vim automatically for you, I use Arch so I installed it with Sudo pacman -S python-pynvim Line = re.sub(self.pattern, " " * int(end / 2), line) """ Iindent plugin: Black can't stop me from using 2 spaces """ which its implementation turned out to be suspiciously simple: import pynvim So I'd recommend to keep using this plugin and use a simple command that replaces each 4 spaces at the beginning of each line with 2.
It looks like the forks that implemented this feature are abandoned or not as maintained as the upstream repository. The lack of the explanation to why they are not and won't support it makes me think that it is not a matter of religiously sticking to a subset of PEP8 (which recommended 4 spaces, in 2001) but a matter of enforcing their personal preference on the world. Which makes me wonder why, I can't imagine this change requiring anything other than a minimal change to the code, It looks like the Black Python code formatter intentionally does not allow you to configure whether to use 2 or 4 spaces,
