This class is a subclass of ``PackageRequirement``, and helps specifying |
|
7
|
|
|
requirements from ``pip``, without using the manager name. |
|
8
|
|
|
|
|
9
|
|
|
You should use the ``multiple`` method if you have more |
|
10
|
|
|
requirements from the same manager. This can receive both tuples of |
|
11
|
|
|
strings, in case you want a specific version, or a simple string, in |
|
12
|
|
|
case you want the latest version to be specified. |
|
13
|
|
|
|
|
14
|
|
|
This is the case where you would provide strings only, to specify the |
|
15
|
|
|
latest version automatically: |
|
16
|
|
|
|
|
17
|
|
|
>>> REQUIREMENTS = PythonRequirement.multiple( |
|
18
|
|
|
... 'coala_decorators', 'setuptools') |
|
19
|
|
|
|
|
20
|
|
|
And if you choose to mix them, specifying version for some and for some |
|
21
|
|
|
not: |
|
22
|
|
|
|
|
23
|
|
|
>>> REQUIREMENTS = PythonRequirement.multiple( |
|
24
|
|
|
... 'coala_decorators', ('setuptools', '19.2')) |
|
25
|
|
|
|
|
26
|
|
|
Lists are also valid arguments: |
|
27
|
|
|
|
|
28
|
|
|
>>> REQUIREMENTS = PythonRequirement.multiple( |
|
29
|
|
|
... ['coala_decorators', '19.2'],) |
|
30
|
|
|
|
|
31
|
|
|
In case you provide too many arguments into the tuple, an error will be |
|
32
|
|
|
raised: |
|
33
|
|
|
|
|
34
|
|
|
>>> REQUIREMENTS = PythonRequirement.multiple( |
|
35
|
|
|
... 'coala_decorators', ('setuptools', '19.2', 'colorama')) |
