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.
Add toxml/fromxml for XML encoding, mighe be lossy on ordering
fromxml has {seq:bool} to add #seq attributes to improve ordering
toxml has {indent:number} to choose space indent depth
Add tojson, same as in jq but also has {indent:number} options
Add toyaml/fromyaml for YAML
Add totoml/fromtoml for TOML
Add tojq/fromjq for jq-flavored JSON (optional quotes for keys, comments and trailing commas support)
Add tocsv/fromcsv for CSV
formcvs takes {comma:string, comment:string} for custom separtor and comment character
Rename/split hex into tohex/fromhex
Rename/split base64 into tobase64/frombase64
tobase64/frombase64 takes {encoding:string} option for base64 flavour (std, url, rawstd, rawurl)
Add to/from<format> urlpath, urlquery, url, xmlentities, base64, hex
Add to<hash> md4, md5, sha1, sha256, sha512, sha3_224, sha3_256, sha3_384, sha3_512
Add to/from<encoding> iso8859-1, utf8, utf16, utf16le, utf16be
interp: Refactor format help and also include options
interp: Add -o name=@path to load file content as value (not documented yet, might change)
interp,decode: Expose decode out value as _out (might change)
interp: Refactor foramts.jq into format_{decode,func,include}.jq
interp: Refactor torepr into _format_func for generic format function overloading
interp: Refactor -o options parsing to be more generic and collect unknowns options to be used as format options
decode of decode alises
func for format overloaded functions
include for format specific jq functions (also _help, torepr etc)
flac_frame: Add bits_per_sample option
mp3: Add max_unique_header_config and max_sync_seek options
mp4: Add decode_samples and allow_truncate options
avc_au: Has length_size option
hevc_au: Has length_size option
aac_frame: Has object_typee option
doc: Rewrite format doc generation, less hack more jq
repl now rewrites query to do implicit display inside the sub eval.
This makes it possible to interrupt eval and output in a better and faster way.
Make JSON encoder fail early on errors.
Add more interrupt tests.
Now repl, slurp and help implemented using same query rewrite.
Include filename context in error if possible.
Add spew function that does opposite of slurp.
Start of help infra, not done or documented yet.
Show error pointer on parse error.
Rename internal eval to _eval and make eval be wrapper that
does rewrite and has various eror handling etc.
Nicer repl, slupr and help errors.
