+### TODO and ideas
+
+#### CLI and REPL
+
+- ctxstack index cancel wrong order skip?
+- Pager for long output. Configurable? `$PAGER`? only explicit with some kind of syntax? `.. | less` but how?
+- Nicer context cancel message
+- `dump` cancel output of large root value, ex: `.frames`. Problem is dump is done by parent repl. 
+- Error position "^" pointer?
+- Configurable history file/name?
+- Reset color at prompt? context cancel
+- Auto complete $variables
+
+#### Language
+
+- Variables somehow? global `$VAR`?
+- Cleanup/Make binary buffers make sense.
+- gojq uses golang `int` for slice indexes, might be issue for non-64bit cpus
+
+#### Functions
+
+- buffer truncate, left/right pad?
+- `toimage`? can be done in CLI with "\x1b]1337" but maybe something for a UI?
+- `toplot`?
+- `dump` should handle binary, make column code more generic? share with `hexdump`? (bindump also?)
+- `dump` colorize/notify row range discontinuity
+- `dump` truncate long arrays in output unless verbose? `dd`?
+- `hexdump` etc should handle binary non byte aligned data
+- `tojvalue` handle binary somehow, base64 string, truncate? md5 digest etc? configurable? `{binarystring: "md5"}`
+- Function to search in binary data, regexp?
+- `grep` like function somehow?
+- Cleanup rework cipher functions, `ctr(aes("key"), "iv")` or `cipher(ctr("iv"), aes("key))`?
+- `open` when to close file?
+- Safe mode interpreter?
+- Allow/deny `open` in autocomplete
+- `open` leak, file and ctxreadseeker
+
+### Tests
+
+- WRITE_ACTUAL does not preserve comment order
+- empty file test
+- CLI tests, raw write, colors?
+- Interactive tests
+- Completion tests
+
+#### Documentation
+
+- Nicer README, repl example (generate somehow)
+- `help("topic")`?
+- Generate from source
+- `-n`, `inputs/0` and `input/0` behavior. Same as jq.
+- Mention `empty.something`?
+- `repl` behavior
+  - `1,2,3 | repl` will start 3 repl:s
+  - Behave same as CLi expres: iterate over all inputs `[1,2,3] | repl({}; .[])`
+- Known issus and confusing things
+  - Symbolic number has to use `._symbol` for now. For example matroska ids are number ID:s that have symbolic string names.
+- Use https://github.com/fadado/JBOL/blob/master/doc/JQ-Distilled.md notation
+- Decoder write guide
+  - Endian inherited per buffer, reset on new buffer
+  - Invalid on zero length input, assert one valid frame etc
+  - Try validate input to make it not ambiguous with other decoders
+  - Try to not seek and read at end while validating or early, will break progress indicator if not
+  - Split bit flags etc into a field with subfields for each bit
+  - Try keep code as declarative as possible
+  - Split into multiple sub formats if possible
+  - See the decoded tree as user interface but still has to represent the actual bit structure
+
+#### Decode
+
+- Store original filename somewhere? root description?
+- Nicer DSL
+  - More optional things? optional args or return value to modify?
+- nicer "synthetic" values? now zero length
+- Value should have raw, tranlated, symbolic and description? struct of map functions?
+  - If symbolic should resolve to string? would make `.field == "abc"` work instead of now `.field._symbolic`
+- Array as root value, adts, avc_au etc
+- Decode framed/limited? framed adds unknown fields?
+- Add unknown for arrays?
+- Cleanup and rethink nested buffers (zip, muxed like ogg)
+  - Root of nested buffer, what range?
+- `dump` has some bug not showing buffer "nesting" level in the address column
+- Endian bitfield helper (elf etc)
+- Cleanup checksums, should just be fields and add warning if mismatch?
+- Decoder in jq
+  - Use jq array/object syntax and pass around decode context, collect fields and build tree
+- Somehow control/limit nested decoding, depth/exclude/include? `probe({depth:1})` etc? per format skip options?
+- `json` decoder?
+- Can't use range while decoding, not calculated yet
+- Keep track of encoding for values, u16le, utf8, varint etc
+
+#### Formats
+
+- Pass argument to format
+- Move format helpers like `mp4_path` to mp4 format code?
+- Value decoder in jq `u(32)`, `u32`?
+- Warnings and errors
+  - `mp4` sample counts
+  - `flac` truncated picture, mix sample rate, bitdepth etc?
+- `protobuf` schema?
+- `matroska` crc
+- `mp4` styp segment test
+- Document maturity/completeness
+- Refactor *[]decode.Format into something more abstract, group?
+- Add `dsf` format
+- Make `json` format more normal? is a bit a of a special case now
+
+#### Scripts
+
+- Summary script, tree with format specific summaries like codec, sample count etc etc?
+- Probe tool with common field names
+- MIME codec encode/decoder "avc1.PPCCLL" etc https://tools.ietf.org/html/rfc6381#section-3.3
+- Validate scripts for mp4, matroska
+
+#### gojq
+
+- `JQValue` tests
+- Common errors with gojq? re-implemented now
+- `JQValue` update/assign function in interface, proper or just one to return error for now
+- `join` can be exponential, try add with strings faster, use add `["a","b","c"] | add`?
+- `0b` -> `1.7976931348623157e+308` something fishy with bin/hex/... literals change
+- Do something similar to `builtin.go` in gojq to speedup a bit
+- remove `scopedump`?
+
+#### Readline
+
+- Use something else than `github.com/chzyer/readline`?
+- Fix backspace as start clears whole line bug
+- Undo ctrl+_ would be nice
+
+#### Big things
+
+- UI, web interface? multiple repl windows? nicer way of showing overlapping fiends in hex etc?
+- jupyter notebook integration
+- FUSE interface
+- Lazy decode, should work on known sizes? could also save memory be re-decode?

+# Implementation details
+
+- fq uses a gojq fork that can be found at https://github.com/wader/gojq/tree/fq (the "fq" branch)
+- cli readline uses raw mode so blocks ctrl-c to become a SIGINT
+- TODO: `scope` and `scopedump` functions used to implement REPL completion
+- TODO: Custom object interface used to traverse fq's field tree and to allowing a terse
+syntax for comparing and working with fields, accessing child fields and special properties like `_range`.
+
+## Decoder implementation help
+
+- Main goal in the end is to produce a tree that is user-friendly and easy to work with.
+So there are always excepts to these rules and sometimes it might be better to let the
+decoder code be a bit ugly over producing a tree that is hard to understand.
+
+- Try use same names, symbols, constant number base etc as in specification
+
+- TODO: Decode only what you know. If possible let "parent" decide what to do with unknown bits by using `*Decode*Len/Range/Limit`  funcitions
+
+- Use sub decoders if possible for frames, metadata etc. You can pass data between them. Also makes it possible to call them separately
+
+- Try to no decode to much as one field or value. A length encoded int could be two fields, a flags byte can be struct with bit fields.
+
+- Try to have add symbols for all named constants.

+
+## Langauge
+
+fq is based on the [jq language](https://stedolan.github.io/jq/) and for basic usage its syntax
+is similar to how object and array access looks in JavaScript or JSON path, `.food[10]` etc.
+
+To get the most out of fq it's recommended to learn more about jq, here are some good starting points:
+
+- [jq manual](https://stedolan.github.io/jq/manual/)
+- [jq Cookbook](https://github.com/stedolan/jq/wiki/Cookbook),
+[FAQ](https://github.com/stedolan/jq/wiki/FAQ),
+[Pitfalls](https://github.com/stedolan/jq/wiki/How-to:-Avoid-Pitfalls)
+
+The most common beginner gotcha is probably jq's use of `;` and `,`. jq uses `;` as argument separator.
+To call `f` with two arguments use `f(a; b)`. If you do `f(a, b)` you will pass a single generator
+expression `a, b` to `f`.
+
+### Differences to jq
+
+- [gojq's differences to jq](https://github.com/itchyny/gojq#difference-to-jq),
+notable is support for arbitrary-precision integers.
+- Supports hexdecimal `0xab`, octal `0o77` and binary `0b101` integer literals
+- Has bitwise operations, `band`, `bor`, `bxor`, `bsl`, `bsr`, `bnot`
+- Has `div` integer division operator
+- Try include `include "file?";` that don't fail if file is missing
+- Possible for a value to act as a object with keys even when it's an array, number etc.
+- There can be keys hidden from `keys` and `[]`. Used for, `_format`, `_bytes` etc.
+- Some values do not support to be updated
+
+### Functions
+
+- All standard library functions from jq
+- `open` open file for reading
+- `probe` or `decode` try to automatically detect format and decode
+- `mp3`, `matroska`, ..., `<name>`, `decode([name])` try decode as format
+- `d`/`display` display value
+- `v`/`verbose` display value verbosely
+- `p`/`preview` show preview of field tree
+- `hd`/`hexdump` hexdump value
+- `repl` nested REPL
+
+### Decoded values (TODO: better name?)
+
+When you decode something successfully in fq you will get a value. A value work a bit like
+jq object with special abilities and is used to represent a tree structure of the decoded
+binary data. Each value always has a name, type and a bit range.
+
+A value has these special keys:
+
+- `_name` name of value
+- `_value` jq value of value
+- `_start` bit range start
+- `_stop` bit range stop
+- `_len` bit range length (TODO: rename)
+- `_bits` bits in range as a binary
+- `_bytes` bits in range as binary using byte units
+- `_path` jq path to value
+- `_unknown` value is un-decoded gap
+- `_symbol` symbolic string representation of value (optional)
+- `_description` longer description of value (optional)
+- `_format` name of decoded format (optional)
+- `_error` error message (optional)
+
+- TODO: unknown gaps
+
+### Binary and IO lists
+
+- TODO: similar to erlang io lists, [], binary, string (utf8) and numbers
+
+## Configuration
+
+To add own functions you can use `init.fq` that will be read from
+- `$HOME/Library/Application Support/fq/init.jq` on macOS
+- `$HOME/.config/fq/init.jq` on Linux, BSD etc
+- `%AppData%\fq\init.jq` on Windows (TODO: not tested)

+## Own decoders and use as library
+
+TODO
+
+
+### Useful tricks
+
+#### `.. | select(...)` fails with `expected an ... but got: ...`
+
+Try add `select(...)?` the select expression assumes it will get and object etc.
+
+#### Manual decode
+
+Sometimes fq fails to decode or you know there is valid data buried inside some binary or maybe
+you know the format of some unknown value. Then you can decode manually.
+
+<pre>
+# try decode a `mp3_frame` that failed to decode
+$ fq file.mp3 .unknown0 mp3_frame
+# skip first 10 bytes then decode as `mp3_frame`
+$ fq file.mp3 .unknown0._bytes[10:] mp3_frame
+</pre>
+
+#### appending to array is slow
+
+Try to use `map` or `foreach` instead.
+
+#### Use `print` and `println` to produce more friendly compact output
+
+```
+> [[0,"a"],[1,"b"]]
+[
+  [
+    0,
+    "a"
+  ],
+  [
+    1,
+    "b"
+  ]
+]
+> [[0,"a"],[1,"b"]] | .[] | "\(.[0]): \(.[1])" | println
+0: a
+1: b
+```
+
+#### Run interactive mode with no input
+```sh
+fq -i
+null>
+```
