7 This small script modifies Vim_’s indentation behavior to comply with PEP8_ and my aesthetic preferences.
8 Most importantly::
9
10    foobar(foo,
11           bar)
12
13 and::
14
15    foobar(
16       foo,

21 Installation
22 ------------
23
24
25 Pathogen
26 ^^^^^^^^
27
28 Follow the instructions on installing Pathogen_ and then:
29
30 .. code-block:: shell-session
31
32    $ cd ~/.vim/bundle
33    $ git clone https://github.com/hynek/vim-python-pep8-indent.git
34
35
36 Vundle
37 ^^^^^^
38
39 Follow the instructions on installing Vundle_ and add the appropriate plugin line into your ``.vimrc``:
40
41 .. code-block:: vim
42
43    Plugin 'hynek/vim-python-pep8-indent'
44
45
46 NeoBundle
47 ^^^^^^^^^
48
49 Follow the instructions on installing NeoBundle_ and add the appropriate NeoBundle line into your ``.vimrc``:
50
51 .. code-block:: vim
52
53    NeoBundle 'hynek/vim-python-pep8-indent'
54
55
56 Configuration
57 -------------
58
59 python_pep8_indent_multiline_string
60 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
61
62 You can configure the initial indentation of multiline strings using ``g:python_pep8_indent_multiline_string`` (which can also be set per buffer).
63 This defaults to ``0``, which means that multiline strings are not indented.
64 ``-1`` and positive values will be used as-is, where ``-1`` is a special value for Vim's ``indentexpr``, and will keep the existing indent (using Vim's ``autoindent`` setting).
65 ``-2`` is meant to be used for strings that are wrapped with ``textwrap.dedent`` etc.  It will add a level of indentation if the multiline string started in the previous line, without any content in it already::
66
67    testdir.makeconftest("""
68        _
69
70 With content already, it will be aligned to the opening parenthesis::
71
72    testdir.makeconftest("""def pytest_addoption(parser):
73                         _
74
75 Existing indentation (including ``0``) in multiline strings will be kept, so this setting only applies to the indentation of new/empty lines.

78 Notes
79 -----
80
81 Please note that Kirill Klenov’s python-mode_ ships its own version of this bundle.
82 Therefore, if you want to use this version specifically, you’ll have to disable python-mode’s using:
83
84 .. code-block:: vim
85
86    let g:pymode_indent = 0

89 License and Authorship
90 ----------------------
91
92 This script is based on one from Vim’s official `script repo`_  that was *not* originally written by me.
93 Unfortunately the indentation was off by one character in one case and the script hasn’t been updated since 2005.
94
95 Even more unfortunately, I wasn’t able to reach any of the original authors/maintainers:
96 **David Bustos** and **Eric Mc Sween**.
97
98 So I fixed the annoyance with the help of `Steve Losh`_ and am putting it out here so you don’t have to patch the original yourself.
99 The original patch is still available here_.
100
101 Over the time a lot more improvements have been contributed_ by `generous people`_.
102
103 I’d like to thank the original authors here for their work and release it hereby to the *Public Domain* (using the CC0_ licence) since I hope that would be in their spirit.
104 If anyone with a say in this objects, please let me_ know immediately.
105 Also, if someone is in contact with one of them, I would appreciate being introduced.
106
107 While my Vimscript_ skills are still feeble, I intend to maintain it for now.
108 This mainly means that I’ll triage through bugs and pull requests but won’t be fixing much myself.
