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
Feels less cluttered, easier to read and more consistent.
Still keep tovalue, tobytes etc that are more basic functions this
only renamed format related functions.
Also there is an exceptin for to/fromjson as it comes from jq.
Also fixes lots of spelling errors while reading thru.
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.
Refactor mp4 decoder to be simpler and have fallback for unknown box type
Cleanup some old ilst hacks
Add generic string reader to decode API that takes an encoding parameters
raw format was a hack to skip decoding to be able to get a binary using tobyte etc.
Now you can do fq -d bytes ... instead of fq -d raw 'tobytes | ...'
Rework time helpers to use new functions
Fix panic in tar decoder where sym value might be missing
Still not very happy about the API but it's getting better.
Markdown is used as is in online documentation and in cli the markdown decoder
is used to decode and the some jq code massages it into something cli friendly.
Was just too much of a mess to have doc in jq.
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.
Doing it thru a propery in the decode fn feels a bit hidden and will
also not get set on failed decoding.
Now array is not range sorted, logic is you care about index number and ordering.
Struct is range sorted as you will prefer to fields by name.
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.
