Brace expansion AST node.

Represents brace expansion patterns like {a,b,c} or {1..10}.

Types

  • :list - Comma-separated alternatives: {a,b,c}
  • :range - Sequence generation: {1..10}, {a..z}, {1..10..2}

Examples

# List: {a,b,c}
%BraceExpand{type: :list, items: ["a", "b", "c"]}

# Numeric range: {1..5}
%BraceExpand{type: :range, range_start: "1", range_end: "5"}

# Range with step: {1..10..2}
%BraceExpand{type: :range, range_start: "1", range_end: "10", step: 2}

# Zero-padded: {01..05}
%BraceExpand{type: :range, range_start: "01", range_end: "05", zero_pad: 2}
