# stylish-haskell configuration file
# ==================================

# The stylish-haskell tool is mainly configured by specifying steps. These steps
# are a list, so they have an order, and one specific step may appear more than
# once (if needed). Each file is processed by these steps in the given order.
steps:
  # Convert some ASCII sequences to their Unicode equivalents. This is disabled
  # by default.
  # - unicode_syntax:
  #     # In order to make this work, we also need to insert the UnicodeSyntax
  #     # language pragma. If this flag is set to true, we insert it when it's
  #     # not already present. You may want to disable it if you configure
  #     # language extensions using some other method than pragmas. Default:
  #     # true.
  #     add_language_pragma: true

  # Format module header
  #
  # Currently, this option is not configurable and will format all exports and
  # module declarations to minimize diffs
  #
  # - module_header:
  #     # How many spaces use for indentation in the module header.
  #     indent: 4
  #
  #     # Should export lists be sorted?  Sorting is only performed within the
  #     # export section, as delineated by Haddock comments.
  #     sort: true
  #
  #     # See `separate_lists` for the `imports` step.
  #     separate_lists: true

  # Format record definitions. This is disabled by default.
  #
  # You can control the layout of record fields. The only rules that can't be configured
  # are these:
  #
  # - "|" is always aligned with "="
  # - "," in fields is always aligned with "{"
  # - "}" is likewise always aligned with "{"
  #
  # - records:
  #     # How to format equals sign between type constructor and data constructor.
  #     # Possible values:
  #     # - "same_line" -- leave "=" AND data constructor on the same line as the type constructor.
  #     # - "indent N" -- insert a new line and N spaces from the beginning of the next line.
  #     equals: "indent 2"
  #
  #     # How to format first field of each record constructor.
  #     # Possible values:
  #     # - "same_line" -- "{" and first field goes on the same line as the data constructor.
  #     # - "indent N" -- insert a new line and N spaces from the beginning of the data constructor
  #     first_field: "indent 2"
  #
  #     # How many spaces to insert between the column with "," and the beginning of the comment in the next line.
  #     field_comment: 2
  #
  #     # How many spaces to insert before "deriving" clause. Deriving clauses are always on separate lines.
  #     deriving: 2
  #
  #     # How many spaces to insert before "via" clause counted from indentation of deriving clause
  #     # Possible values:
  #     # - "same_line" -- "via" part goes on the same line as "deriving" keyword.
  #     # - "indent N" -- insert a new line and N spaces from the beginning of "deriving" keyword.
  #     via: "indent 2"
  #
  #     # Sort typeclass names in the "deriving" list alphabetically.
  #     sort_deriving: true
  #
  #     # Wheter or not to break enums onto several lines
  #     #
  #     # Default: false
  #     break_enums: false
  #
  #     # Whether or not to break single constructor data types before `=` sign
  #     #
  #     # Default: true
  #     break_single_constructors: true
  #
  #     # Whether or not to curry constraints on function.
  #     #
  #     # E.g: @allValues :: Enum a => Bounded a => Proxy a -> [a]@
  #     #
  #     # Instead of @allValues :: (Enum a, Bounded a) => Proxy a -> [a]@
  #     #
  #     # Default: false
  #     curried_context: false

  # Align the right hand side of some elements.  This is quite conservative
  # and only applies to statements where each element occupies a single
  # line.
  # Possible values:
  # - always - Always align statements.
  # - adjacent - Align statements that are on adjacent lines in groups.
  # - never - Never align statements.
  # All default to always.
  - simple_align:
      cases: always
      top_level_patterns: always
      records: always
      multi_way_if: always

  # Import cleanup
  - imports:
      # There are different ways we can align names and lists.
      #
      # - global: Align the import names and import list throughout the entire
      #   file.
      #
      # - file: Like global, but don't add padding when there are no qualified
      #   imports in the file.
      #
      # - group: Only align the imports per group (a group is formed by adjacent
      #   import lines).
      #
      # - none: Do not perform any alignment.
      #
      # Default: global.
      align: global

      # The following options affect only import list alignment.
      #
      # List align has following options:
      #
      # - after_alias: Import list is aligned with end of import including
      #   'as' and 'hiding' keywords.
      #
      #   > import qualified Data.List      as List (concat, foldl, foldr, head,
      #   >                                          init, last, length)
      #
      # - with_alias: Import list is aligned with start of alias or hiding.
      #
      #   > import qualified Data.List      as List (concat, foldl, foldr, head,
      #   >                                 init, last, length)
      #
      # - with_module_name: Import list is aligned `list_padding` spaces after
      #   the module name.
      #
      #   > import qualified Data.List      as List (concat, foldl, foldr, head,
      #                          init, last, length)
      #
      #   This is mainly intended for use with `pad_module_names: false`.
      #
      #   > import qualified Data.List as List (concat, foldl, foldr, head,
      #                          init, last, length, scanl, scanr, take, drop,
      #                          sort, nub)
      #
      # - new_line: Import list starts always on new line.
      #
      #   > import qualified Data.List      as List
      #   >     (concat, foldl, foldr, head, init, last, length)

      # Long list align style takes effect when import is too long. This is
      # determined by 'columns' setting.
      #
      # - inline: This option will put as much specs on same line as possible.
      #
      # - new_line: Import list will start on new line.
      #
      # - new_line_multiline: Import list will start on new line when it's
      #   short enough to fit to single line. Otherwise it'll be multiline.
      #
      # - multiline: One line per import list entry.
      #   Type with constructor list acts like single import.
      #
      #   > import qualified Data.Map as M

      # Default: inline
      long_list_align: multiline

      # Align empty list (importing instances)
      #
      # Empty list align has following options
      #
      # - inherit: inherit list_align setting
      #
      # - right_after: () is right after the module name:
      #
      #   > import Vector.Instances ()
      #
      # Default: inherit
      empty_list_align: inherit

      # List padding determines indentation of import list on lines after import.
      # This option affects 'long_list_align'.
      #
      # - <integer>: constant value
      #
      # - module_name: align under start of module name.
      #   Useful for 'file' and 'group' align settings.
      #
      # Default: 4
      list_padding: 4

      # Separate lists option affects formatting of import list for type
      # or class. The only difference is single space between type and list
      # of constructors, selectors and class functions.
      #
      # - true: There is single space between Foldable type and list of it's
      #   functions.
      #
      #   > import Data.Foldable (Foldable (fold, foldl, foldMap))
      #
      # - false: There is no space between Foldable type and list of it's
      #   functions.

      #
      # Default: true
      separate_lists: true

      # Space surround option affects formatting of import lists on a single
      # line. The only difference is single space after the initial
      # parenthesis and a single space before the terminal parenthesis.
      #
      # - true: There is single space associated with the enclosing
      #   parenthesis.
      #
      #   > import Data.Foo ( foo )
      #
      # - false: There is no space associated with the enclosing parenthesis

      # Default: false
      space_surround: false

      # Enabling this argument will use the new GHC lib parse to format imports.
      #
      # This currently assumes a few things, it will assume that you want post
      # qualified imports. It is also not as feature complete as the old
      # imports formatting.
      #
      # It does not remove redundant lines or merge lines. As such, the full
      # feature scope is still pending.
      #
      # It _is_ however, a fine alternative if you are using features that are
      # not parseable by haskell src extensions and you're comfortable with the
      # presets.
      #
      # Default: false
      ghc_lib_parser: false

  # Language pragmas
  - language_pragmas:
      # We can generate different styles of language pragma lists.
      #
      # - vertical: Vertical-spaced language pragmas, one per line.
      #
      # - compact: A more compact style.
      #
      # - compact_line: Similar to compact, but wrap each line with
      #   `{-#LANGUAGE #-}'.
      #
      # Default: vertical.
      style: vertical

      # Align affects alignment of closing pragma brackets.
      #
      # - true: Brackets are aligned in same column.
      #
      # - false: Brackets are not aligned together. There is only one space
      #   between actual import and closing bracket.
      #
      # Default: true
      align: true

      # stylish-haskell can detect redundancy of some language pragmas. If this
      # is set to true, it will remove those redundant pragmas. Default: true.
      remove_redundant: true

      # Language prefix to be used for pragma declaration, this allows you to
      # use other options non case-sensitive like "language" or "Language".
      # If a non correct String is provided, it will default to: LANGUAGE.
      language_prefix: LANGUAGE

  # Replace tabs by spaces. This is disabled by default.
  # - tabs:
  #     # Number of spaces to use for each tab. Default: 8, as specified by the
  #     # Haskell report.
  #     spaces: 8

  # Remove trailing whitespace
  - trailing_whitespace: {}

  # Squash multiple spaces between the left and right hand sides of some
  # elements into single spaces. Basically, this undoes the effect of
  # simple_align but is a bit less conservative.
  # - squash: {}

# A common setting is the number of columns (parts of) code will be wrapped
# to. Different steps take this into account.
#
# Set this to null to disable all line wrapping.
#
# Default: 80.
columns: 80

# By default, line endings are converted according to the OS. You can override
# preferred format here.
#
# - native: Native newline format. CRLF on Windows, LF on other OSes.
#
# - lf: Convert to LF ("\n").
#
# - crlf: Convert to CRLF ("\r\n").
#
# Default: native.
newline: native

# Sometimes, language extensions are specified in a cabal file or from the
# command line instead of using language pragmas in the file. stylish-haskell
# needs to be aware of these, so it can parse the file correctly.
#
# No language extensions are enabled by default.
# language_extensions:
  # - TemplateHaskell
  # - QuasiQuotes

# Attempt to find the cabal file in ancestors of the current directory, and
# parse options (currently only language extensions) from that.
