License: https://github.com/python-babel/babel/blob/master/LICENSE
|
|
|
|
Changes from upstream:
|
|
- Preserve arguments, babel's parser flattened all values in args,
|
|
we need order because we use different syntax for translation
|
|
which can contain 2nd arg which is array of many values. If
|
|
argument is non-primitive type then value is NOT returned in
|
|
args.
|
|
E.g. __("0", ["1", "2"], "3") -> ("0", None, "3")
|
|
- remove comments support
|
|
- changed signature to accept string directly.
|
|
|
|
:param code: code as string
|
|
:param keywords: a list of keywords (i.e. function names) that should be
|
|
recognized as translation functions
|
|
:param options: a dictionary of additional options (optional)
|
|
Supported options are:
|
|
* `template_string` -- set to false to disable ES6
|
|
template string support.
