Other Plugins & Linters

• flake8-implicit-str-concat Flake8 plugin to encourage correct string literal concatenation. flake8-no-implicit-concat is different from this plugin because there are cases where this plugin prefers implicit concatenations over explicit + operators.
• wemake-python-styleguide Set of strict flake8 rules with several plugins as dependencies. It implements WPS326 Found implicit string concatenation, which also checks implicit string concatenations, as one of the many rules it defines.
• pylint This linter has implicit-str-concat rule. By default it only looks for occurrences of implicit concatenations on the same line, but it has --check-str-concat-over-line-jumps=y option to enable checking of concatenations over multiple lines.

Development

Use tools like Pipenv:

pipenv run python -m pip install -e .[dev]
pipenv run make check
