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.
8+ # Convert some ASCII sequences to their Unicode equivalents. This is disabled
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:
16+ # add_language_pragma: true
20+ # There are different ways we can align names and lists.
22+ # - global: Align the import names and import list throughout the entire
25+ # - file: Like global, but don't add padding when there are no qualified
26+ # imports in the file.
28+ # - group: Only align the imports per group (a group is formed by adjacent
31+ # - none: Do not perform any alignment.
36+ # Folowing options affect only import list alignment.
38+ # List align has following options:
40+ # - after_alias: Import list is aligned with end of import including
41+ # 'as' and 'hiding' keywords.
43+ # > import qualified Data.List as List (concat, foldl, foldr, head,
44+ # > init, last, length)
46+ # - with_alias: Import list is aligned with start of alias or hiding.
48+ # > import qualified Data.List as List (concat, foldl, foldr, head,
49+ # > init, last, length)
51+ # - new_line: Import list starts always on new line.
53+ # > import qualified Data.List as List
54+ # > (concat, foldl, foldr, head, init, last, length)
56+ # Default: after_alias
57+ list_align: after_alias
59+ # Long list align style takes effect when import is too long. This is
60+ # determined by 'columns' setting.
62+ # - inline: This option will put as much specs on same line as possible.
64+ # - new_line: Import list will start on new line.
66+ # - new_line_multiline: Import list will start on new line when it's
67+ # short enough to fit to single line. Otherwise it'll be multiline.
69+ # - multiline: One line per import list entry.
70+ # Type with contructor list acts like single import.
72+ # > import qualified Data.Map as M
80+ long_list_align: inline
82+ # List padding determines indentation of import list on lines after import.
83+ # This option affects 'list_align' and 'long_list_align'.
86+ # Separate lists option affects formating of import list for type
87+ # or class. The only difference is single space between type and list
88+ # of constructors, selectors and class functions.
90+ # - true: There is single space between Foldable type and list of it's
93+ # > import Data.Foldable (Foldable (fold, foldl, foldMap))
95+ # - false: There is no space between Foldable type and list of it's
98+ # > import Data.Foldable (Foldable(fold, foldl, foldMap))
101+ separate_lists: false
105+ # We can generate different styles of language pragma lists.
107+ # - vertical: Vertical-spaced language pragmas, one per line.
109+ # - compact: A more compact style.
111+ # - compact_line: Similar to compact, but wrap each line with
112+ # `{-#LANGUAGE #-}'.
114+ # Default: vertical.
117+ # Align affects alignment of closing pragma brackets.
119+ # - true: Brackets are aligned in same collumn.
121+ # - false: Brackets are not aligned together. There is only one space
122+ # between actual import and closing bracket.
127+ # stylish-haskell can detect redundancy of some language pragmas. If this
128+ # is set to true, it will remove those redundant pragmas. Default: true.
129+ remove_redundant: true
131+ # Align the types in record declarations
134+ # Replace tabs by spaces. This is disabled by default.
136+ # # Number of spaces to use for each tab. Default: 8, as specified by the
140+ # Remove trailing whitespace
141+ - trailing_whitespace: {}
143+# A common setting is the number of columns (parts of) code will be wrapped
144+# to. Different steps take this into account. Default: 80.
147+# Sometimes, language extensions are specified in a cabal file or from the
148+# command line instead of using language pragmas in the file. stylish-haskell
149+# needs to be aware of these, so it can parse the file correctly.
151+# No language extensions are enabled by default.
152+# language_extensions:
