Warns about incorrect gettext usage.

Project description

Flake8 i18n plugin

Way too often using gettext in python results in one of the following errors:

_(f”{context_variable}”)

Not only gettext will not work here because fstring interpolation happens before function call, but using gettext tools for collecting translation keys results in:

File “/usr/lib/python3.6/site-packages/babel/messages/extract.py”,

line 480, in extract_python value = eval(code, {‘__builtins__’: {}}, {})

File “<string>”, line 2, in <module> NameError: name ‘context_variable’ is not defined

Similar cases are

_(“%s” % value)

and

_(“{}”.format(value))

which will not trigger a collection error, but will still result in an incorrect key name in gettext function call.

This flake8 extensions provides basic checks for the above cases.

Install

Install with pip:

$ pip install flake8-i18n

Configure

Add following into your .flake8 file

i18nfuncs =

gettext ngettext myfunny_gettext _

Otherwise the default function name list is

gettext ngettext _

Using string interpolation inside gettext will now result in one of the following:

I001 fstring is resolved before function call

I002 format is resolved before function call

I003 printf is resolved before function call
