Helper module for parsing ANSI escape sequences.

This module provides common utilities for parsing and handling ANSI sequences, extracted from duplicate implementations in other ANSI-related modules.

Summary

Functions

parse_params(params)

Parses parameters from an ANSI sequence.

parse_sequence(sequence, operation_decoder)

Generic parser for ANSI sequences that follow the pattern: params + operation code.

Functions

parse_params(params)

@spec parse_params(binary()) :: {:ok, [integer()]} | :error

Parses parameters from an ANSI sequence.

Splits the parameter string by semicolons and converts them to integers.

Returns

  • {:ok, params} - Successfully parsed parameters
  • :error - Failed to parse parameters

parse_sequence(sequence, operation_decoder)

@spec parse_sequence(binary(), function()) :: {:ok, atom(), [integer()]} | :error

Generic parser for ANSI sequences that follow the pattern: params + operation code.

Parameters

  • sequence - The binary sequence to parse
  • operation_decoder - Function to decode operation from character code

Returns

  • {:ok, operation, params} - Successfully parsed sequence
  • :error - Failed to parse sequence
