Devyn Cairns c61075e20e Add string/binary type color to ByteStream (#12897) ... # Description This PR allows byte streams to optionally be colored as being specifically binary or string data, which guarantees that they'll be converted to `Binary` or `String` appropriately on `into_value()`, making them compatible with `Type` guarantees. This makes them significantly more broadly usable for command input and output. There is still an `Unknown` type for byte streams coming from external commands, which uses the same behavior as we previously did where it's a string if it's UTF-8. A small number of commands were updated to take advantage of this, just to prove the point. I will be adding more after this merges. # User-Facing Changes - New types in `describe`: `string (stream)`, `binary (stream)` - These commands now return a stream if their input was a stream: - `into binary` - `into string` - `bytes collect` - `str join` - `first` (binary) - `last` (binary) - `take` (binary) - `skip` (binary) - Streams that are explicitly binary colored will print as a streaming hexdump - example: ```nushell 1.. | each { into binary } | bytes collect ``` # Tests + Formatting I've added some tests to cover it at a basic level, and it doesn't break anything existing, but I do think more would be nice. Some of those will come when I modify more commands to stream. # After Submitting There are a few things I'm not quite satisfied with: - **String trimming behavior.** We automatically trim newlines from streams from external commands, but I don't think we should do this with internal commands. If I call a command that happens to turn my string into a stream, I don't want the newline to suddenly disappear. I changed this to specifically do it only on `Child` and `File`, but I don't know if this is quite right, and maybe we should bring back the old flag for `trim_end_newline` - **Known binary always resulting in a hexdump.** It would be nice to have a `print --raw`, so that we can put binary data on stdout explicitly if we want to. This PR doesn't change how external commands work though - they still dump straight to stdout. Otherwise, here's the normal checklist: - [ ] release notes - [ ] docs update for plugin protocol changes (added `type` field) --------- Co-authored-by: Ian Manske <ian.manske@pm.me>		2024-05-20 00:35:32 +00:00
