cc52a4419d id3v2: Decode subframes for CTOC and add struct for headers 2023-03-05 19:29:22 +01:00

8e0dde03d0 decode: Support multiple format args and some rename and refactor
This will allow passing both cli options and format options to sub decoder.
Ex: pass keylog option to a tls decoder when decoding a pcap.
Ex: pass decode options to a format inside a http body inside a pcap.

Add ArgAs method to lookup argument based on type. This also makes the format
decode function have same signature as sub decoders in the decode API.

This change decode.Format a bit:
DecodeFn is now just func(d *D) any
DecodeInArg renamed to DefaultInArg

9b81d4d3ab decode: More type safe API and split scalar into multiple types
Preparation to make decoder use less memory and API more type safe.
Now each scalar type has it's own struct type so it can store different
things and enables to have a scalar interface.
Also own types will enable experimenting with decode DLS designs like
using chained methods that are type aware.

e77f776999 decode,interp: Rename unknown gap fields from "unknown#" to "gap#"
Think it makes it clearer and also less likely to collide with a field
name a deocder wants to use.

c3a0686c9e mp3_frame_tags: Refactor and rename xing format to mp3_frame_tags
Make more sense to use a more general name when there is both info and xing
and possibly vbri in the future. Also both xing and info seems to have extension
fields

Remove some old tests that are not really needed anymore.

cf15661e9c mp3_frame: Add LSF support and fix incorrect main data handling
Some mpeg versions use LSF (low sampling frequency) when encoding
low sample rates which changes a bit how the side info is layed out.

Also skip trying to separate data and other_data as after reading up
a bit on how main data begin and bit reservoir works i think it was done
incorrectly. To know the real audio data length i think you need to decode
the huffman tables. Instead just have a "audio_data" field which are the
bits with audo data for current and possibly following frames.

29005c70bf interp,dump: Show address bar for root, nested roots and on format change
Also increase indent for nested roots a bit.

cae288e6be format,intepr: Refactor json, yaml, etc into formats also move out related functions
json, yaml, toml, xml, html, csv are now normal formats and most of them also particiate
in probing (not html and csv).

Also fixes a bunch of bugs in to/fromxml, to/fromjq etc.

1ddea1ada3 interp,format: Refactor registry usage and use function helpers
Move registry to interp and add support for functions and filesystems.
This will be used later for allow formats to add own functions and fq code.

Add gojqextra function helpers to have more comfortable API to add functions.
Takes care of argument type casting and JQValue:s and some more things.

Refactor interp package to use new function helper and registry. Probably
fixes a bunch of JQValue bugs and other type errors.

Refactor out some mpeg nal things to mpeg format.

Refactor interp jq code into display.q and init.jq.

Remove undocumented aes_ctr funciton, was a test. Hopefully will add more crypto things laster.

dump: Makes it a bit easier to understand array of arrays/structs.
avro_ocf: Rename ocf.go -> avro_ocr.go to have same name of source file as format
pcap,pcapng: Rename tcp flow struct to tcp_connection, makes more sense i think

e238f292af repl: Speedup multi input to sub-repl
Rewrite non-sub-repl queries as "q" -> ".[] | q" and pass in inputs as array.
Before each input did an eval.

Also fixup error message a bit, skip line:column when they dont make sense.

fc0aacb654 interp: Cleanup display aliases, now: d, da, dd, dv, ddv
Think it makes sense to have them all start with d.
Also f is often used as function argument name.

8d2d88f4d0 mp3: Decrease max sync seek length between frames to 4k
This might break mp3s with large id3v2 chunks embedded into the stream but
i think that is rare and probably means it is a dump of a mp3 radio stream etc.

An alternative approach is to also look for id3v2 etc between frames but then the mp3
root value probably should be an array of mix of things instead of a struct, or rename
header/footer to metadata?
