+# 0.11.0
+
+New iNES/NES 2.0 ROM decoder (thanks @mlofjard) and basic JPEG 2000 format support. jq language improvements and fixes from gojq. And as always various decoder improvements and fixes.
+
+## Changes
+
+- Add `string_truncate` option to configure how to truncate long strings when displaying a decode value tree. `dd`, `dv` etc set truncate length to zero to not truncate. #919
+- gojq updates from upstream:
+  - Implement `ltrim`, `rtrim`, and `trim` functions
+  - Fix object construction with duplicate keys (`{x:0,y:1} | {a:.x,a:.y}`)
+  - Fix `halt` and `halt_error` functions to stop the command execution immediately
+  - Fix variable scope of binding syntax (`"a" as $v | def f: $v; "b" as $v | f`)
+  - Fix `ltrimstr` and `rtrimstr` functions to emit error on non-string input
+  - Fix `nearbyint` and `rint` functions to round ties to even
+  - Improve parser to allow `reduce`, `foreach`, `if`, `try`-`catch` syntax as object values
+  - Remove `pow10` in favor of `exp10`, define `scalbn` and `scalbln` by `ldexp`
+- Fix issue using decode value with `ltrimstr`/`rtrimstr`.
+
+## Format changes
+
+- `fit`
+  - Skip array fields on pre read messages. #878
+  - Fixed subfield referencing fields below self in message. #877
+- `jp2c` New JPEG 2000 codestream decoder. #928
+- `icc_profile` Strip whitespace in header and tag strings. #912
+- `mp4`
+  - Add `jp2c`, `jp2h`, `ihdr` `jP` JPEG 2000 related boxes support. #928
+  - Add `thmb` box support. #897
+  - Turns out for qt brand `hdlr` component name might be zero bytes. #896
+- `nes` New iNES/NES 2.0 ROM decoder (thanks @mlofjard). #893

+# 0.10.0
+
+Adds support for various LevelDB formats (thanks @mikez) and Garmin Flexible and Interoperable Data Transfer format (FIT) (thanks @mlofjard).
+
+And as usual some small fixes and dependency updates.
+
+## Changes
+
+- On macOS fq now reads init script from `~/.config/fq` in addition to `~/Library/Application Support/fq`. #871
+- Switch readline module from own fork to https://github.com/ergochat/readline #854
+- Updated gojq fork. Notable changes from upstream below. #844
+  - Fix pre-defined variables to be available in initial modules
+  - Fix object construction with duplicate keys
+
+## Format changes
+
+- `aac_frame` Decode instance tag and common window flag. #859
+- `fit` Add support for Garmin Flexible and Interoperable Data Transfer decoder. Thanks @mlofjard #874
+  - This format is used by various GPS tracking devices to record location, speed etc.
+  - Example of converting position information to KML:
+  ```jq
+  # to_kml.jq
+  # convert locations in a fit structure to KML
+  def to_kml:
+    ( [ .data_records[].data_message as {position_lat: $lat, position_long: $long}
+      | select($lat and $long)
+      | [$long, $lat, 0]
+      | join(",")
+      ]
+    | join(". ")
+    | { kml: {"@xmlns":"http://earth.google.com/kml/2.0"
+      , Document: {Placemark: {LineString: {coordinates: .}}}}
+      }
+    | to_xml({indent:2})
+    );
+  ```
+  Usage:
+  ```sh
+  # -L to add current directory to library path
+  # -r for raw string output
+  # 'include "to_ml";' to include to_kml.jq
+  # to_kml calls to_kml function
+  $ fq -L . -r 'include "to_kml"; to_kml' file.fit > file.kml
+  ```
+
+- `hevc_sps` Fix some incorrect profile_tier_level decoding. #829
+- `html` Fix issue parsing elements including SOLIDUS "/". #870
+  - Upstream issue https://github.com/golang/go/issues/63402
+- `mpeg_es` Support ES_ID_Inc and decode descriptors for IOD tags
+- `leveldb_descriptor`, `leveldb_log`, `leveldb_table` Add support for LevelDB. Thanks @mikez #824
+  - This format is used by many database backends and applications like Google chrome.
+- `pcapng` Decode all section headers instead of just the first. #860
+- `png` Fix incorrect decoding of type flags. #847
+- `hevc_sps` Fix incorrect decoding of profile_tier_level. #829
+- `tls` Fix field name typos. #839
+- `mp4`
+  - Don't try decode samples for a track that has an external reference. #834
+  - Use box structure instead of track id to keep track for sample table data. #833
+  - `ctts` box v0 sample offset seems to be signed in practice but not in spec. #832
+- `webp` Decode width, height and flags for lossless WebP. #857

 Tool, language and decoders for working with binary data.

+TLDR: it aims to be jq, hexdump, dd and gdb for files combined into one.
+
 ![fq demo](doc/demo.svg)

-Basic usage is `fq . file` or `fq d file`.
+Basic usage is `fq . file`, `fq d file` or `fq 'some query' file ...`.

 For details see [usage.md](doc/usage.md).

 ### Background

-fq is inspired by the well known jq tool and language that allows you to work with binary formats the same way you would using jq. In addition it can present data like a hex viewer, transform, slice and concatenate binary data. It also supports nested formats and has an interactive REPL with auto-completion.
+fq is inspired by the [jq](https://jqlang.github.io/jq/) tool and language and allows you to work with binary formats in the same way. In addition to using jq expressions it can also present decoded tree structures, transform, slice and concatenate binary data. It also supports nested formats and features an interactive REPL with auto-completion of functions and names.

-It was originally designed to query, inspect and debug media codecs and containers like mp4, flac, mp3, jpeg. But since then it has been extended to support a variety of formats like executables, packet captures (with TCP reassembly) and serialization formats like JSON, YAML, XML, ASN1 BER, Avro, CBOR, protobuf. In addition it also has functions to work with URLs, convert to/from hex, number bases, search for things etc.
-
-In summary it aims to be jq, hexdump, dd and gdb for files combined into one.
-
-**NOTE:** fq is still early in development so things might change, be broken or do not make sense. That also means that there is a great opportunity to help out!

+### Limitations
+
+- Fields with subcomponents, such as "compressed_speed_distance" field on globalMessageNumber 20 is not represented correctly. 
+  The field is read as 3 separate bytes where the first 12 bits are speed and the last 12 bits are distance.
+- There are still lots of UNKOWN fields due to gaps in Garmins SDK Profile documentation. (Currently FIT SDK 21.126)
+- Compressed timestamp messages are not accumulated against last known full timestamp.

+### Limitations
+
+- `prg_rom`, `chr_rom` and `trainer` fields may contain data that is just random
+  junk from the memory chips, since they are of a fixed size.
+- The `nes_toasm` function outputs ALL opcodes, including the unofficial ones,
+  which means that none of the regular assemblers can recompile it.
+- The `nes_tokitty` function works on tiles in `chr_rom` but only outputs a Kitty
+  graphics compatible string. You need to manually `printf` that string to get
+  Kitty (or another compatible terminal) to output the graphics.
+
+### Decompile PRG ROM
+```
+$ fq -r '.prg_rom[] | nes_toasm' file.nes
+```
+
+### Print out first CHR ROM tile in Kitty (or Konsole, wayst, WezTerm) at size 5
+```
+$ printf $(fq -r -d nes '.chr_rom[0] | nes_tokitty(5)' file.nes)

+
+### Print out all CHR ROM tiles in Kitty (with Bash) at size 5

+## Solving part of the FRA pcap challenge 2021-09 using fq
+
+**CAUTION:** fq is still in early development so things might change but i will try to keep the guide updated.
+
+This guide will show how to work with fq and how to use the jq language. It will also show some useful things from the standard library of jq and fq. We will walk thru one of the challenges from [FRA challenge](https://challenge.fra.se/) that are challenges [FRA](https://www.fra.se/) (~Swedish NSA) published as part of their recruitment effort. The challenge can be downloaded from [pcap-challenge-2021-09.tgz](https://challenge.fra.se/pcap-challenge-2021-09.tgz) but it can also be found in the same directory as this README file.
+
+Start by running fq on the file to get an overview:
+
+```

+
+The first columns shows the start address of each line, second and third a hex and ASCII dump and the forth a hierarchical tree representation of the decoded values. At the top we see that the file was detected as `gzip`. The tree shows various compression details and that fq has detected that the uncompressed bytes are a `tar` archive, also the `{}` hints that there are more values inside the uncompressed field.
+
+Of course it's probably easiest to just extract the archive instead using fq but for the case of learning it's probably useful to use something familiar to show how to navigate it using fq.
+
+Now start an interactive [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop) (`-i`):
+```
+$ fq -i . pcap-challenge-2021-09.tgz
+gzip>
+```
+
+The First thing we see is a prompt indicating the current "input" which is the root of the gzip file. If we type `.`, it will show the same output as above. `.` is the "identity" function in jq which does nothing, it just outputs what it gets as input. By default fq:s REPL will try to display what the expression is evaluated to in some useful way.
+
+To recursively display the whole tree we can use `d` (short for `display`) or `f` (short for `display({array_truncate: 0})`) which will do the same but not truncate long arrays.
+
+Note that the REPL supports auto-completion of functions and fields using tab, there is history support using arrow keys and the prompt supports basic readline shortcuts (same as bash etc).
+
+To look into the tar archive we can do:
+
+```
+gzip> .uncompressed

+
+`files[0:3]` mean that `files` is an array with 3 values, shown using the jq "slice" syntax `start:end`.

+
+This uses the jq "each" operator `[]` which will output all values in an array (or object), then we use `.name` on each output to get the name.
+
+If we want to access just the name and not display the hexdump columns etc, we can use the "pipe" operator and filter each value thru `tovalue` which will convert it into some JSON compatible.
+
+```
+gzip> .uncompressed.files[].name | tovalue
+"triangle.pcap"
+"triangles.py"
+"README.txt"
+```
+
+Or if we want to have the names in an array:
+
+```
+gzip> [.uncompressed.files[].name]
+[
+  "triangle.pcap",
+  "triangles.py",
+  "README.txt"
+]
+```
+
+Here we use the `[...]` array constructor which will collect all outputs from the expression between the brackets. `tovalue` is not needed in this case as the `.name` decode values in the array knows how to behave as JSON values. But note that the values still are decode values. Consider the difference:
+
+```
+gzip> [.uncompressed.files[].name][1]

+gzip> [.uncompressed.files[].name | tovalue][1]
+"triangles.py"
+```
+
+As a side note jq's standard library has a `map` function that does exactly this `.uncompressed.files | map(.name)`. To learn more one can look at [how map is implemented](https://github.com/stedolan/jq/blob/master/src/builtin.jq), look for `def map(f):`.
+
+Back to the challenge and have a look at content of the `README.txt` file:
+
+```
+gzip> .uncompressed.files[2].data | println
+FRA Pcap Challenge 2021-09

+
+Lycka till!
+```
+
+It's instructions in Swedish telling us to take various screenshots of a space ship flying around in space.
+
+Here we used `println` which convert it's input to a string and prints it to stdout (and outputs nothing, more on that later).
+
+Let's have a look at the PCAP file:
+
+```

+
+It has 5705 captured packets, no IPv4 fragments and there was one reassembled TCP connection.
+
+First time I ran fq on this pcap it could not decode much as it did not support "linux_ssl". It was not that much work to add support, which is a reminder that if fq does not support something it might not be that far away from supporting it.
+
+Now have a look at the streams from the TCP connection:
+
+```

+```
+
+Looks like the client sent lots of "z" and "m ", maybe key strokes to control a ship? The server has responded with something that looks like 4727629 bytes of JSON. it's probably a bad idea to display the whole string, let's show the first 2000 bytes as a string.

+
+We use the slice syntax to slice from character 0 to 2000. We use the word characters (UTF-8 codepoints) here as raw bits are by default represented as strings in fq. To get access to raw bits there are functions like `tobytes` etc.
+
+There are two `{"msg_type": ... }` and the first one ends with `... }\n` so it's probably JSON lines. Let's split on `\n` and have a look:

+
+`split("\n")` splits a string on some boundary, "\n" in this case, and output AN array with all the parts. We then use `.[0,1,-2,-1]` to get the first, second, second from the end and last string from the array (negative indexes counts from the end).
+
+Here we VERB MISSING the output operator `,` which is a way in jq to return or "output" more than one value. What happens is that for each value `0`,`1`, `-2` and `-1` the program "forks" and continueS to run and then aT some point it will "backtrack" back to THE next value and so on. To learn more one can read all about it on
+[jq internals](https://github.com/stedolan/jq/wiki/Internals%3A-backtracking).
+
+This is also how jq arrays are expressed, remember `[...]`? let's try `[0,1,-2,-1]`:
+
+```
+gzip> [0,1,-2,-1]
+[
+  0,
+  1,
+  -2,
+  -1
+]
+```
+
+`[...]` "collects" the output from the expression `0,1-2,-1` and to show that what is inside the brackets is just an expression we can do:
+
+```
+gzip> [(0,(1,2))]
+[
+  0,
+  1,
+  2
+]
+```
+
+and to go full circle we can use a multiple output expression as a array index:
+
+```
+gzip> [1,2,3][0,1,2]
+1
+2
+3
+```
+
+first we build an array by collecting `1,2,3` and then we index into it using `0,1,2`, getting the values at index `0`, `1` and `2`.
+
+Now back to the JSON lines. We see that the last is just an empty string, probably because the streams end with a new line. Let's filter it out, convert the other lines into useable values and then make things a bit more comfortable by starting a new REPL.
+
+```
+gzip> .uncompressed.files[0].data.tcp_connections[0].server_stream | split("\n") | map(select(. != "") | fromjson) | repl
+> [object, ...][13842][]>
+```
+
+We `map` here to do something for each line. `select` is A function that given a condition will output its input or otherwise it will return `empty`, in this case removing all empty strings. Then we pipe all the non-empty lines to `fromjson`, which converts JSON represention into a jq value. Lastly we pipe the result to `repl`, which will start a new nested REPL.
+
+The prompt tells us that the input is an array with 13842 values, the first value is an object.
+
+Let's have look using `.[0,1,-2,-1]` again. `.` here is the current input.
+
+```

+```
+
+Looks like nested JSON and some of the values are encrypted.
+
+Maybe we can get some overview by filtering out things that seems to change in each message and see what is left:
+
+```
+> [object, ...][13842]> count_by(del(.md5) | del(.data))
+[
+  [
+    {
+      "encoding": "ascii",
+      "msg_type": "code"
+    },
+    1
+  ],
+  [
+    {
+      "encoding": "ascii",
+      "msg_type": "update"
+    },
+    708
+  ],
+  [
+    {
+      "encoding": "long_xor",
+      "msg_type": "code"
+    },
+    2
+  ],
+  [
+    {
+      "encoding": "xor",
+      "msg_type": "update"
+    },
+    13131
+  ]
+]
+```
+
+Here we use `count_by` which is a fq function similar to the jq function `unique_by` but instead of groping all unique values it just counts them, returning an array with `[unique value, count]` pairs. In jq `_by` is convension used by some functions to allow ad-hoc transform something before using it. For example `count` count number of unique values but `count_by` will count unique values after from transformation, in this case the transformation `del(.md5) | del(.data)` which will remove the keys `md5` and `data` from an object.
+
+How does the first two "xor" encoded messages looks like:
+
+```
+> [object, ...][0:13842]> map(select(.encoding == "xor")) | .[0:2]
+[
+  {
+    "data": "3c652e23657d6774757e7f767f6b6765333e3722657d67651528242c656b67653f657d67757e776b67653e657d677671776b6765352833657d677f736b676524282b283534657d671c652035222229656b6765302f2e3322651a6b676537282e293334657d671c74776b6773776b6773776b6776776b6773771a3a",
+    "encoding": "xor",
+    "md5": "2074c8a4effcbaa0ceec11754cfa66c3",
+    "msg_type": "update"
+  },
+  {
+    "data": "3c652e23657d67717373707f736b6765333e3722657d67651528242c656b67653f657d677474776b67653e657d67767f776b6765352833657d677476716b676524282b283534657d671c652035222229656b6765302f2e3322651a6b676537282e293334657d671c74776b6773776b6773776b6776776b6773771a3a",

+    "md5": "8f772df87dd20c5a41109b6ed84efb46",
+    "msg_type": "update"
+  }
+]
+```
+
+The common `3c652e23657d67` prefix is suspicious and looks hex encoded and probably some encrypted form of `{"id": ` judging by how other "update" messages look. There was "long_xor" so maybe this is just per byte xor? XOR is symmetric so we should get the key if we encrypt some known plaintext with its encrypted version.
+
+```
+> [object, ...][13842]> bxor(("{" | explode)[0]; ("3c" | hex | explode)[0])
+71
+```
+
+`explode` is a jq functions that turn a string into an array of its codepoints. `hex` decodes a hex string into a bytes buffer but we use it as string here. We then bitwise XOR using `bxor` and get the key `71`.
+
+Notice that jq uses the argument separator `;` not `,`.
+
+Now try bitwise XOR all codepoints with `71`:
+
+```
+> [object, ...][13842]> .[-2].data | hex | explode | map(bxor(.; 71)) | implode
+"{\"id\": 107029, \"type\": \"Flower\", \"x\": 230.0, \"y\": 340.0, \"rot\": 0}"
+```
+
+Ok that looks like JSON to me. Now let's have a look at "long_xor" with "msg_type" "code", maybe it starts with `class `?.
+
+```
+> [object, ...][13842]> ["class " | explode, ("241e00051a54" | hex | explode)] | transpose | map(bxor(.[0]; .[1])) | implode
+"Gravit"
+```
+
+That looks like it could be a start of a key. I noticed earlier while poking around that the hex decoded data for a "code" message has parts that looks like english text.
+
+```
+> [object, ...][0:13842]> .[1].data | hex | tostring | scan("\\w*force\\w*"; "i")
+"YfORCEgR"
+"YfORCEgR"
+"ITYfORCE"
+"YfORCEgR"
+"UfORCEgRAVITYfORCE"
+"ITYfORCE5"
+```
+
+`scan` is jq function that outputs all non-overlapping strings matching a regexp. `"i"` is to match case-insensitive.
+
+A good guess is probably that the key is `"GravityForce"` repeated. Why it shows up and have weird casing is probably because the plain text has long streaks of whitespace `0x32` which happens to be the bit in encoding ASCII encoding changing between upper/lower case.
+
+Let's try decrypt it using it:
+
+```
+> [object, ...][13842]> .[1].data | hex | [., ("GravityForce"*100)[0:length]] | map(explode) | transpose | map(bxor(.[0]; .[1])) | implode
+"class Rock(Object):\n    def __init__(self, x, y, colors=['green', 'white'], points=[35,100,120,100,75,90]):\n        Object.__init__(self, x, y)\n        self.points=points\n        self.colors=colors\n        self.rot=random.randint(0,359)\n\n    def render(self, buf, center_x, center_y):\n        self.buf=buf\n        self.img=Image.new(mode='RGB', size=(IMAGE_RESOLUTION['X'], IMAGE_RESOLUTION['Y']))\n\n        d=ImageDraw.Draw(self.img)\n\n\n        coords=[(IMAGE_RESOLUTION['X']/2+ampl*math.sin(rad),IMAGE_RESOLUTION['Y']/2-ampl*math.cos(rad)) for (rad,ampl) in zip([i*2*math.pi/len(self.points) for i in range(len(self.points))], self.points)]\n\n        d.polygon(coords,                 outline=self.colors[0], fill=self.colors[1] )\n\n\n        self.image2ascii(self.img, self.game2image(self.x, self.y, center_x, center_y))\n        return self.buf\n\n    "
+```
+
+Looks like python to me.
+
+`("GravityForce"*100)[0:length]` is a quick trick to make sure the key is repeated and has the same length as the encrypted message. `length` is a function that returns the length of its input.
+
+Now decrypt all data strings and use `fromjson` again and start a new REPL:
+
+```
+> [object, ...][0:13842]> map(if .encoding == "xor" then .data |= (hex | explode | map(bxor(.; 71)) | implode) elif .encoding == "long_xor" then .data |= (hex | [., ("GravityForce"*100)[0:length]] | map(explode) | transpose | map(bxor(.[0]; .[1])) | implode) end | if .msg_type == "update" then .data |= fromjson end) | repl
+>> [object, ...][0:13842]>
+```
+
+We can break this down a bit:
+```
+map(
+  ( if .encoding == "xor" then
+      .data |= (hex | explode | map(bxor(.; 71)) | implode)
+    elif .encoding == "long_xor" then
+      .data |= (hex | [., ("GravityForce"*100)[0:length]] | map(explode) | transpose | map(bxor(.[0]; .[1])) | implode)
+    end
+  | if .msg_type == "update" then .data |= fromjson end
+  )
+) | repl
+```
+
+TODO: break this down more
+
+A few new things here. `if` is A plain old if-statement, conditionally do something, that can have optional `elif`/`else` branches. `.key |= ...` is a shorthand for `.key = (.key | ...)` which will update a keys value in an object using the current value as input.
+
+Now have a look at `.[0,1,-2,-1]` again:
+
+```
+>> [object, ...][0:13842]> .[0,1,-2,-1]
+{
+  "data": "class Player(Object):\n    def __init__(self, x, y):\n        Object.__init__(self, x, y)\n\n        self.MAX_ROTATION_SPEED=7\n        self.MAX_SPEED=0.1\n        self.MAX_THRUST=0.01\n        self.SPEED_REDUCTION=1.01\n\n    def render(self, buf, center_x, center_y):\n        self.buf=buf\n        self.img=Image.new(mode='RGB', size=(IMAGE_RESOLUTION['X'], IMAGE_RESOLUTION['Y']))\n\n        d=ImageDraw.Draw(self.img)\n\n        d.polygon(((IMAGE_RESOLUTION['X']/2, IMAGE_RESOLUTION['Y']/2-50),                   (IMAGE_RESOLUTION['X']/2+25, IMAGE_RESOLUTION['Y']/2+50),                   (IMAGE_RESOLUTION['X']/2, IMAGE_RESOLUTION['Y']/2+20),                   (IMAGE_RESOLUTION['X']/2-25, IMAGE_RESOLUTION['Y']/2+50),                  ),                 outline='green', fill='cyan')\n\n        self.image2ascii(self.img, self.game2image(self.x, self.y, center_x, center_y))\n        return self.buf\n    ",

+```
+
+Much better. So it's information what shapes to draw and position and rotation updates per object. Maybe try collect the final state for all objects so that we can draw an ending "screenshot"?
+
+```
+>> [object, ...][0:13842]> reduce (.[] | select(.msg_type == "update")) as $msg ({}; .[$msg.data.id | tostring] = $msg.data) | repl
+>>> object> length

+  "x": 253.65325300861684,
+  "y": 352.330474276039
+}
+```
+
+Here we use `reduce` which is a special expression to "accumulate" something, the syntax is `reduce <generator> as $var (<init>; <update>)`. As generator we select all "update" messages and let each output be named `$msg`, our init value is `{}` an empty object and for each messagee we update the object using the object id found in the message with the data for that message.
+
+This should be enough to draw something. To make things a bit more manageable there is cleaned up version of all that also has some helper functions to generates a screenshot as a SVG file. It also shows how to use fq as a script interpreter.
+
+TODO: how to create own functions?
+
+Have a look at [pcap-challenge-2021-09.jq](pcap-challenge-2021-09.jq).
+
+To run the script do something like this, assuming you have fq in `PATH`:

+### Limitations
+
+- Fields with subcomponents, such as "compressed_speed_distance" field on globalMessageNumber 20 is not represented correctly. 
+  The field is read as 3 separate bytes where the first 12 bits are speed and the last 12 bits are distance.
+- There are still lots of UNKOWN fields due to gaps in Garmins SDK Profile documentation. (Currently FIT SDK 21.126)
+- Compressed timestamp messages are not accumulated against last known full timestamp.
+
+### Convert stream of data messages to JSON array
+
+```
+$ fq '[.data_records[] | select(.record_header.message_type == "data").data_message]' file.fit
