+
+# sendosc
+
+Simple NodeJS script for sending OSC via TCP or UDP originally inspired by this [c++ utility](https://github.com/yoggy/sendosc) of the same name.
+
+## Usage
+
+```
+Usage: sendosc [options]
+
+simple util to sendosc
+
+Options:
+  -V, --version          output the version number
+  --protocol <protocol>  Network protocol (choices: "tcp", "udp", default: "udp")
+  --host <host>          the host to send osc to
+  --port <port>          the port to send osc to
+  --address <address>    OSC address
+  --args <args...>       osc args (default: [])
+  --slip                 slip encode message (default: false)
+  --types <types...>     osc arg types (choices: "s", "i", "f", "b", default: [])
+  -h, --help             display help for command
+```
+
+- using npx `npx sendosc@latest --host 127.0.0.1 --port 9999 --address /hello`
+- install using `npm install -g sendosc@latest` and run `sendosc --host 127.0.0.1 --port 9999 --address /hello`
+
+## Notes
+
+- `--types` option is a space seperate list of type characters that will determine what the corresponding argument type will be set to
+  - optional
+  - uses type codes from the OSC spec
+- `--args` option is a space-separated list of arguments. If a corresponding type is not found in the `--types` option it will default to string (`s`).
+  - blobs (`b`) are to be entered as hex string representing the buffer to be sent so the ASCII string `hello` would be `68656c6c6f`
+- the default protocol is UDP but can be changed to TCP using the `--protocol` flag
+
+## Examples
+
+- `sendosc --host 127.0.0.1 --port 8000 --address /test --args 1.0`
+- `sendosc --protocol tcp --host 127.0.0.1 --port 8000 --address /this/is/sent/via/tcp`
+- `sendosc --host 127.0.0.1 --port 8000 --address /test/with/types --args 1 2.0 three --types i f`
+  - note that `types` is not the same length as `args` so the remaining argument (`three`) will default to string
+- `sendosc --host 127.0.0.1 --port 8000 --address /blob --args 68656c6c6f --types b`
