Formaty
A simple configurable binary data parser. Data structures are described using TOML files.
Formats
All formats in formats are included in the formaty
binary. See formats.md for
more info.
Configuration
Format
A format is a collection of fields that describe the structure of data, so it can be parsed
Members:
name
- name of the format, used as the argument when selecting the format to parse the data asbit_flip
- should individual bytes have their bits flipped within, individual fields can override thisfields
- 1 or more fields to describe the structure of the data
Field
A field is a collection of bits that make up some sort of data. Formaty supports Int
/Uint
of arbitrary size,
Float
, Double
, Strings
and Bytes
. This data may not be byte aligned.
Members:
name
- the name of the field, used while displaying datafield_type
- the type of the field and associated dataprint_type
- how to print the data, if not provided it uses the default print for a typebit_flip
- overrides the global bit flip field, defaults to false if not provided
Field Types
UInt
/Int
: standard integer types. Unsigned or signed respectively. Can be 1 or more bits.bit_width
: number of bits composing the integerendianess
: byte ordering of the field
Float
/Double
: Standard float point types of 32-bit or 64-bit widthendianess
: byte ordering of the field
String
: Collection of bytes ended by a null character '\0'max_len
: max length of the dataendianess
: byte ordering of the field
Bytes
: Collection of bytes with no terminationmax_len
: max number of bytesendianess
: byte ordering of the field
Example Config
Example
./formaty ccsds "[0xe0, 0xa1, 0xc0, 0x00, 0x00, 0x05, 0x01, 0x02, 0x03, 0x04, 0x05]"
Output:
Version Number: 0
Packet Type: 1
Secondary Header Flag: 0
APID: 0x200
Sequence Flags: 3
Packet Sequence Count: 0
Data Length: 5
Data: [1, 2, 3, 4, 5]
