Formatting library ("fmt")

This library includes functions and objects for parsing binary and text buffers.

• binary format -- fmt_pack, fmt_unpack, fmt_pack_count, fmt_pack_size
• base64 format -- fmt_base64_encode, fmt_base64_decode
• custom format -- fmt_custom_encode
• text format -- fmt_parser, fmt_text, fmt_charcc

Functions:

• fmt_pack - pack variables into a byte buffer, according to the format string
• fmt_unpack - unpack byte buffer to an array of variables, according to the format string
• fmt_pack_count - returns the number of items found in a packing format string
• fmt_pack_size - returns the number of bytes found in a packing format string
• fmt_base64_encode - encodes a byte buffer in base64 character buffer (A-Za-z0-9+/)
• fmt_base64_decode - decodes a base64 character buffer (A-Za-z0-9+/) to a byte buffer
• fmt_custom_encode - encodes a custom format (selected character codes to numeric version)
• fmt_text - formats specified variables according to the format string
• fmt_parser - creates a text parser object with the specified stream reading function
• fmt_string_parser - creates a text parser object that reads from the specified string
• fmt_file_parser - creates a text parser object that reads from the specified file
• fmt_charcc - checks if a character is in the character class

Objects and their methods:

• fmt_parser - formatted text string-parsing object
  • read - read the specified number of characters from the stream
  • getchar - read one character from the stream
  • readcc - read characters while they match the specified class
  • skipcc - skip characters while they match the specified class
  • read_real - read with the real value character class, optionally return real
  • read_int - read with the integer value character class, optionally return integer
  • read_binary_int - read with the binary integer character class, optionally -return integer
  • read_octal_int - read with the octal integer character class, optionally return -integer
  • read_decimal_int - read with the decimal integer character class, optionally -return integer
  • read_hex_int - read with the hexadecimal integer character class, optionally return -integer
  • check - check for presence of a string in stream
