## Global format options
2022-02-05 20:15:18 +03:00
2021-12-09 19:15:21 +03:00
Currently the only global option is `force` and is used to ignore some format assertion errors. It can be used as a decode option or as a CLI `-o` option:
2022-02-05 20:15:18 +03:00
```
fq -d mp4 -o force=true file.mp4
fq -d raw 'mp4({force: true})' file.mp4
```

2022-01-13 20:34:59 +03:00
2022-02-16 22:13:28 +03:00
- Currently no extra validation is done for CER and DER.
- Does not support specifying a schema.
- Supports `torepr` but without schema all sequences and sets will be arrays.
2022-01-13 20:34:59 +03:00
2021-12-09 19:15:21 +03:00
#### Examples
`frompem` and `topem` can be used to work with PEM format
2022-01-13 20:34:59 +03:00
```

$ fq -d raw 'frompem | asn1_ber | d' cert.pem
2022-01-13 20:34:59 +03:00
```
2021-12-09 19:15:21 +03:00
Can be used to decode nested parts
2022-02-07 19:41:05 +03:00
```
2021-12-09 19:15:21 +03:00
$ fq -d asn1_ber '.constructed[1].value | asn1_ber' file.ber
2022-02-07 19:41:05 +03:00
```
2021-12-09 19:15:21 +03:00
If schema is known and not complicated it can be reproduced
2022-02-07 19:41:05 +03:00
```
2021-12-09 19:15:21 +03:00
$ fq -d asn1_ber 'torepr as $r | ["version", "modulus", "private_exponent", "private_exponen", "prime1", "prime2", "exponent1", "exponent2", "coefficient"] | with_entries({key: .value, value: $r[.key]})' pkcs1.der
2022-02-07 19:41:05 +03:00
```
2022-02-16 22:13:28 +03:00
2021-12-09 19:15:21 +03:00
Supports `torepr`
```

### avro_ocf
2021-12-09 19:15:21 +03:00
Supports reading Avro Object Container Format (OCF) files based on the 1.11.0 specification.
2022-02-10 05:46:12 +03:00
Capable of handling null, deflate, and snappy codecs for data compression.
Limitations:
- Schema does not support self-referential types, only built-in types.
- Decimal logical types are not supported for decoding, will just be treated as their primitive type
