#Python black formatter line length code#

Just in case you’re interested in git hook, the settings is here. Solution 1 This is due to the default line length for black being longer than youd like 88 characters per line. An alternative to consider if the backslashes in the above. Although when the target version is Python 3.9 or higher, Black uses parentheses instead in -preview mode (see below) since they’re allowed in Python 3.9 and higher. Replace 'anizeImports':true by to allow codeActionsOnSave to specify which extension to use for a given on save action, the way faultFormatter or work. You can do this either by using the context menu (right click on a open python file in the editor) and select 'Format Document With. Before Python 3.9 Python’s grammar does not allow organizing parentheses around the series of context managers. PEP 8 recommends limiting docstrings or comments to 72 characters, which is exactly what I’m using for flake8.

It's likely to break some use cases (e.g., embedded code in docstrings), it may produce ugly output (just one word on the next line), and if we reflow too aggressively it can make diffs harder to read. After some days of using above settings, I found a very frustrating behavior that when I pressed Ctrl+S multiple times to save manually a python file, the imports part changed upon each save, and sometimes it even deleted some imports…ĭigged in github, people have already reported the issue. Fortunately, I can still use it for Python 2 by running the following command: 1. I am going to say that reflowing docstrings is out of scope for Black.
