0.4.0

Added

• Syntax-aware diff — ExAST.diff/3, ExAST.diff_files/3, ExAST.apply_diff/1
  • GumTree-inspired AST matching: functions by name/arity, nodes by kind/label/signature
  • Edit classification: :insert, :delete, :update, :move
  • Function reorder detection reported as :move edits
  • Child suppression: child edits covered by a parent are rolled up
  • Inline line-level diffs within updated nodes (Myers algorithm)
  • Patch application: ExAST.apply_diff/1 produces patched source from a diff result
• mix ex_ast.diff CLI task
  • Colored output with -/+ markers (red/green, auto-detected)
  • --no-color, --no-moves, --summary, --json flags
  • Human-readable labels (def create/1 instead of {:def, :create, 1})
• AST and zipper input — Patcher.find_all/3 and Patcher.replace_all/4 now accept source strings, Sourceror.Zipper, or raw AST
• Quoted expressions as patterns — patterns and replacements can be strings or quote blocks:

  Patcher.find_all(source, quote(do: IO.inspect(_)))
  Patcher.replace_all(ast, quote(do: IO.inspect(expr)), quote(do: dbg(expr)))
