flake8-no-implicit-concat
=========================
[Flake8][] plugin that forbids implicit str/bytes literal concatenations.
# Not Allowed
print('foo' 'bar', 'baz')
a = ["aaa",
"bbb"
"ccc"]
b = b'abc' b'def'
# OK
print('foobar', 'baz')
a = ["aaa",
"bbb"
+ "ccc"]
b = b'abcdef'
Installation
------------
Install via pip:
pip install flake8-no-implicit-concat
Violation Codes
---------------
The plugin uses the prefix `NIC`, short for No Implicit Concatenation.
| Code | Description |
| ------ | ---------------------------------------------------------- |
| NIC001 | Implicitly concatenated str literals on one line |
| NIC002 | Implicitly concatenated str literals over multiple lines |
| NIC101 | Implicitly concatenated bytes literals on one line |
| NIC102 | Implicitly concatenated bytes literals over multiple lines |
Other Plugins & Linters
-----------------------
- [**flake8-implicit-str-concat**][flake8-implicit-str-concat]
Flake8 plugin to encourage correct string literal concatenation.
This plugin is different from `flake8-no-implicit-concat`
because this plugin prefers implicit concatenations over explicit `+`
operators when concatenating literals over multiple lines.
- [**wemake-python-styleguide**][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**][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
