| # 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 | ||
|
|
||
| # Align the right hand side of some elements. This is quite conservative | ||
| # and only applies to statements where each element occupies a single | ||
| # line. | ||
| - simple_align: | ||
| cases: true | ||
| top_level_patterns: true | ||
| records: true | ||
|
|
||
| # 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: group | ||
|
|
||
| # Folowing 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) | ||
| # | ||
| # - new_line: Import list starts always on new line. | ||
| # | ||
| # > import qualified Data.List as List | ||
| # > (concat, foldl, foldr, head, init, last, length) | ||
| # | ||
| # Default: after_alias | ||
| list_align: after_alias | ||
|
|
||
| # 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 contructor list acts like single import. | ||
| # | ||
| # > import qualified Data.Map as M | ||
| # > ( empty | ||
| # > , singleton | ||
| # > , ... | ||
| # > , delete | ||
| # > ) | ||
| # | ||
| # Default: inline | ||
| long_list_align: inline | ||
|
|
||
| # 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. | ||
| list_padding: 4 | ||
|
|
||
| # Separate lists option affects formating 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. | ||
| # | ||
| # > import Data.Foldable (Foldable(fold, foldl, foldMap)) | ||
| # | ||
| # Default: true | ||
| separate_lists: true | ||
|
|
||
| # 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 collumn. | ||
| # | ||
| # - 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 | ||
|
|
||
| # 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: {} | ||
|
|
||
| # A common setting is the number of columns (parts of) code will be wrapped | ||
| # to. Different steps take this into account. Default: 80. | ||
| columns: 800 | ||
|
|
||
| # 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 |
