+# Stylish-haskell configuration file used for cardano-sl by Serokell.
+# It's based on default config provided by `stylish-haskell --defaults` but has some changes
+# ==================================
+
+# 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

+      #
+      # - 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).

+      # - compact_line: Similar to compact, but wrap each line with

+  # Replace tabs by spaces. This is disabled by default.

+  #     # 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.
+#
+# Note: we tend to write code which fits into 80 characters, in some cases
+# 100 is acceptable. For imports we always permit 100 characters because it
+# decreases verbosity of diffs and makes merging easier.
+columns: 100
+
+# 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
+
+# These syntax-affecting language extensions are enabled so that
+# stylish-haskell wouldn't fail with parsing errors when processing files
+# in projects that have those extensions enabled in the .cabal file
+# rather than locally.
+#
+# To my best knowledge, no harm should result from enabling an extension
+# that isn't actually used in the file/project. —@neongreen
