1# stylish-haskell configuration file
2# ==================================
4# The stylish-haskell tool is mainly configured by specifying steps. These steps
5# are a list, so they have an order, and one specific step may appear more than
6# once (if needed). Each file is processed by these steps in the given order.
7steps:
8 # Convert some ASCII sequences to their Unicode equivalents. This is disabled
9 # by default.
10 # - unicode_syntax:
11 # # In order to make this work, we also need to insert the UnicodeSyntax
12 # # language pragma. If this flag is set to true, we insert it when it's
13 # # not already present. You may want to disable it if you configure
14 # # language extensions using some other method than pragmas. Default:
15 # # true.
16 # add_language_pragma: true
18 # Align the right hand side of some elements. This is quite conservative
19 # and only applies to statements where each element occupies a single
20 # line.
21 - simple_align:
22 cases: false
23 top_level_patterns: false
24 records: false
26 # Import cleanup
27 - imports:
28 # There are different ways we can align names and lists.
29 #
30 # - global: Align the import names and import list throughout the entire
31 # file.
32 #
33 # - file: Like global, but don't add padding when there are no qualified
34 # imports in the file.
35 #
36 # - group: Only align the imports per group (a group is formed by adjacent
37 # import lines).
38 #
39 # - none: Do not perform any alignment.
40 #
41 # Default: global.
42 align: global
44 # Folowing options affect only import list alignment.
45 #
46 # List align has following options:
47 #
48 # - after_alias: Import list is aligned with end of import including
49 # 'as' and 'hiding' keywords.
50 #
51 # > import qualified Data.List as List (concat, foldl, foldr, head,
52 # > init, last, length)
53 #
54 # - with_alias: Import list is aligned with start of alias or hiding.
55 #
56 # > import qualified Data.List as List (concat, foldl, foldr, head,
57 # > init, last, length)
58 #
59 # - new_line: Import list starts always on new line.
60 #
61 # > import qualified Data.List as List
62 # > (concat, foldl, foldr, head, init, last, length)
63 #
64 # Default: after_alias
65 list_align: new_line
67 # Long list align style takes effect when import is too long. This is
68 # determined by 'columns' setting.
69 #
70 # - inline: This option will put as much specs on same line as possible.
71 #
72 # - new_line: Import list will start on new line.
73 #
74 # - new_line_multiline: Import list will start on new line when it's
75 # short enough to fit to single line. Otherwise it'll be multiline.
76 #
77 # - multiline: One line per import list entry.
78 # Type with contructor list acts like single import.
79 #
80 # > import qualified Data.Map as M
81 # > ( empty
82 # > , singleton
83 # > , ...
84 # > , delete
85 # > )
86 #
87 # Default: inline
88 long_list_align: new_line
90 # Align empty list (importing instances)
91 #
92 # Empty list align has following options
93 #
94 # - inherit: inherit list_align setting
95 #
96 # - right_after: () is right after the module name:
97 #
98 # > import Vector.Instances ()
99 #
100 # Default: inherit
101 empty_list_align: right_after
103 # List padding determines indentation of import list on lines after import.
104 # This option affects 'long_list_align'.
105 #
106 # - <integer>: constant value
107 #
108 # - module_name: align under start of module name.
109 # Useful for 'file' and 'group' align settings.
110 list_padding: module_name
112 # Separate lists option affects formating of import list for type
113 # or class. The only difference is single space between type and list
114 # of constructors, selectors and class functions.
115 #
116 # - true: There is single space between Foldable type and list of it's
117 # functions.
118 #
119 # > import Data.Foldable (Foldable (fold, foldl, foldMap))
120 #
121 # - false: There is no space between Foldable type and list of it's
122 # functions.
123 #
124 # > import Data.Foldable (Foldable(fold, foldl, foldMap))
125 #
126 # Default: true
127 separate_lists: true
129 # Language pragmas
130 - language_pragmas:
131 # We can generate different styles of language pragma lists.
132 #
133 # - vertical: Vertical-spaced language pragmas, one per line.
134 #
135 # - compact: A more compact style.
136 #
137 # - compact_line: Similar to compact, but wrap each line with
138 # `{-#LANGUAGE #-}'.
139 #
140 # Default: vertical.
141 style: vertical
143 # Align affects alignment of closing pragma brackets.
144 #
145 # - true: Brackets are aligned in same collumn.
146 #
147 # - false: Brackets are not aligned together. There is only one space
148 # between actual import and closing bracket.
149 #
150 # Default: true
151 align: true
153 # stylish-haskell can detect redundancy of some language pragmas. If this
154 # is set to true, it will remove those redundant pragmas. Default: true.
155 remove_redundant: true
157 # Replace tabs by spaces. This is disabled by default.
158 # - tabs:
159 # # Number of spaces to use for each tab. Default: 8, as specified by the
160 # # Haskell report.
161 # spaces: 8
163 # Remove trailing whitespace
164 - trailing_whitespace: {}
166# A common setting is the number of columns (parts of) code will be wrapped
167# to. Different steps take this into account. Default: 80.
168columns: 80
170# By default, line endings are converted according to the OS. You can override
171# preferred format here.
173# - native: Native newline format. CRLF on Windows, LF on other OSes.
175# - lf: Convert to LF ("\n").
177# - crlf: Convert to CRLF ("\r\n").
179# Default: native.
180newline: lf
182# Sometimes, language extensions are specified in a cabal file or from the
183# command line instead of using language pragmas in the file. stylish-haskell
184# needs to be aware of these, so it can parse the file correctly.
186# No language extensions are enabled by default.

188 - FlexibleContexts
189 - TemplateHaskell
190 - QuasiQuotes
