ex_brace_expansion

ExBraceExpansion brings bash-style brace expansion functionality to the Elixir ecosystem. It allows developers to generate lists of strings from compact pattern expressions, similar to how shell expansion works in Unix-like environments. This library is useful for file path generation, configuration management, and any scenario requiring systematic string variations.

Key Features

• Pattern Expansion — Converts brace patterns like {a,b,c} into arrays of strings
• Numeric Ranges — Supports numeric sequences with {start..end} and {start..end..step} syntax
• Character Ranges — Handles alphabetical ranges like {a..e} for character sequences
• Nested Braces — Processes complex nested patterns such as {{A..C},{a..c}}
• Zero-padded Numbers — Correctly expands zero-padded numeric ranges like {00..10..5}
• Empty Element Handling — Manages empty elements in patterns like -v{,,}

Philosophy

The project follows a pragmatic approach by porting an established JavaScript implementation to Elixir, ensuring reliability through proven algorithms while integrating naturally with Elixir's functional programming patterns.
