It can understand varint/leb128-delimited/i32be streams, and it can connect to Kafka.\n\n`pq` will pretty-print when outputting to a tty, but you should pipe it to `jq` for more fully-featured json handling.\n\n### Download\n\npq is on [crates.io](https://crates.io/crates/pq): `cargo install pq`. You can also download a static binary from the [releases page](https://github.com/sevagh/pq/releases).\n\n### Usage\n\n**new** You can now pass in a proto file and have pq compile it on the fly using `protoc`:\n\n```\n$ pq --protofile ./tests/protos/dog.proto --msgtype com.example.dog.Dog <./tests/samples/dog\n{\n \"breed\": \"gsd\",\n \"age\": 3,\n \"temperament\": \"excited\"\n}\n```\n\nUse PROTOC and PROTOC_INCLUDE to control the executed protoc binary and configure the `-I=/proto/path` argument (design copied from [prost](https://github.com/danburkert/prost/blob/master/prost-build/src/lib.rs)).\n\nTo set up, put your `*.fdset` files in `~/.pq`, `/etc/pq`, or a different directory specified with the `FDSET_PATH` env var:\n\n```\n$ protoc -o dog.fdset dog.proto\n$ protoc -o person.fdset person.proto\n$ cp *.fdset ~/.pq/\n```\n\nYou can specify additional fdset directories or files via options:\n\n```\n$ pq --msgtype com.example.dog.Dog --fdsetdir ./tests/fdsets <./tests/samples/dog\n$ pq --msgtype com.example.dog.Dog --fdsetfile ./tests/fdsets/dog.fdset <./tests/samples/dog\n```\n\nPipe a single compiled protobuf message:\n\n```\n$ pq --msgtype com.example.dog.Dog <./tests/samples/dog\n{\n \"age\": 4,\n \"breed\": \"poodle\",\n \"temperament\": \"excited\"\n}\n```\n\nPipe a `varint` or `leb128` delimited stream:\n\n```\n$ pq --msgtype com.example.dog.Dog --stream varint <./tests/samples/dog_stream\n{\n \"age\": 10,\n \"breed\": \"gsd\",\n \"temperament\": \"aggressive\"\n}\n```\n\nConsume from a Kafka stream:\n\n```\n$ pq kafka my_topic --brokers 192.168.0.1:9092 --beginning --count 1 --msgtype com.example.dog.Dog\n{\n \"age\": 10,\n \"breed\": \"gsd\",\n \"temperament\": \"aggressive\"\n}\n```\n\nConvert a Kafka stream to varint-delimited:\n\n```\n$ pq kafka my_topic --brokers=192.168.0.1:9092 --count 1 --convert varint |\\\n> pq --msgtype com.example.dog.Dog --stream varint\n{\n \"age\": 10,\n \"breed\": \"gsd\",\n \"temperament\": \"aggressive\"\n}\n```\n\nPipe `kafkacat` output to it:\n```\n$ kafkacat -b 192.168.0.1:9092 -C -u -q -f \"%R%s\" -t my_topic |\\\n> pq --msgtype=com.example.dog.Dog --stream i32be\n{\n \"age\": 10,\n \"breed\": \"gsd\",\n \"temperament\": \"aggressive\"\n}\n```\n\n### Compile without kafka\n\nTo compile `pq` without kafka support, run:\n\n```\n$ cargo build --no-default-features\n```\n\n### Compile for Windows\n\n1. Install [Visual Studio Installer](https://visualstudio.microsoft.com/downloads/) Community edition\n2. Run the installer and install `Visual Studio Build Tools 2019`. You need the `C++ Build Tools` workload. Note that you can't just install the minimal package, you also need `MSVC C++ x64/86 Build Tools` and `Windows 10 SDK`.\n3. Open `x64 Native Tools Command Prompt` from the start menu.\n4. Download and run [`rustup-init.exe`](https://win.rustup.rs/x86_64)\n5. Close and reopen your terminal (so `cargo` will be in your path)\n6. Run `cargo install --no-default-features pq`\n\nNote that this will disable the Kafka feature, which is not currently supported on Windows.\n" }, { "path": "erased-serde-json/.gitignore", "content": "target/\n**/*.rs.bk\n*.sw[po]\nCargo.lock\n" }, { "path": "erased-serde-json/Cargo.toml", "content": "[package]\nname = \"erased_serde_json\"\nversion = \"0.1.3\"\nauthors = [\"Sevag Hanssian \"]\nlicense = \"MIT/Apache-2.0\"\ndescription = \"Type-erased Formatter trait for serde_json::ser::Formatter\"\nrepository = \"https://github.com/sevagh/erased-serde-json\"\ndocumentation = \"https://github.com/sevagh/erased-serde-json\"\nkeywords = [\"json\", \"serde\", \"serialization\"]\ncategories = [\"encoding\"]\nreadme = \"README.md\"\ninclude = [\"Cargo.toml\", \"src/**/*.rs\", \"README.md\", \"LICENSE-APACHE\", \"LICENSE-MIT\"]\nedition = \"2018\"\n\n[dependencies]\nserde = \"1.0\"\nserde_json = \"1.0.2\"\n" }, { "path": "erased-serde-json/LICENSE-APACHE", "content": " Apache License\n Version 2.0, January 2004\n http://www.apache.org/licenses/\n\nTERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION\n\n1.
