+# Details per file setting:
+#   text    These files should be normalized (i.e. convert CRLF to LF).
+#   binary  These files are binary and should not be diffed,
+#           normalized, etc. Only report if the file has changed.
+#           NOTE: "binary" is a macro for -diff -merge -text.
+#
+# Relevant builtin diff patterns (see: https://www.git-scm.com/docs/gitattributes#_defining_a_custom_hunk_header)

+# MACROS #
+# ====================================================================
+# All macros assume the default rule is: `text eol=lf` and sets/removes attributes accordingly
+# If the default rule changes, these macros must be updated as well.
+
+# OVERRIDES
+## See builtin binary definition here: https://www.git-scm.com/docs/gitattributes#_defining_macro_attributes
+[attr]binary        -text -diff -merge !eol
+
+# CUSTOM
+
+### Prevent end-of-line conversion
+[attr]input         -text -eol
+
+## Diff Macros
+### Useful for declaring which diff pattern to use for files that may
+### not be captured correctly by Git's heuristics.
+[attr]bash          diff=bash
+[attr]css           diff=css
+[attr]html          diff=html
+[attr]xml           diff=html
+[attr]markdown      diff=markdown
+[attr]python        diff=python
+[attr]ruby          diff=ruby
+[attr]scheme        diff=scheme
+
+### Do not generate a diff, instead print a "Binary files differ" message
+### Useful for autogenerated text files that may produce large, noisy diffs
+[attr]autogen       -diff
+[attr]lockfile      -diff
+
+### Fix syntax highlighting on GitHub to allow comments
+[attr]jsonc         linguist-language=JSON-with-Comments
