descriptiona simple interactive OSC (Open Sound Control) debugger for terminal
Karnpapon Boonput (karnpapon)




Build Release crates.io

oscd, a simple interactive OSC debugger for the terminal by using nom as a lexer/parser, oscd offers auto type casting and support sending multiple osc arguments.

It has two simple features:

  • Monitor OSC messages (over UDP) sent to a port
  • Send OSC messages (over UDP) to a port
    • default port = 57110
    • default address =

Install / Run

  • easiest way is to cargo install oscd
  • alternative way is downloading latest released binary files, unzip and put it where executable file lives based on your Operating System eg. usr/local/bin (for OSX)
  • type oscd to run program


  • Use the following format to send messages: <address> <argument>
  • <address> is osc path to communicate with.
  • <argument> is a number or a string (double quotes can be omitted) and can have multiple arguments.
  • eg. /s_new "default" -1 0 0 "freq" 850, will be parsed as ("s_new", [String("default"), Int(-1), Int(0), Int(0), String("freq"), Int(850)]))
  • by default oscd automatically casting type for you, and it also support numeric literals type conversion
    • eg. 65.4321_f64 is equivalent to 65.4321 as f64 (Explicit conversion)
    • it will be parsed osc as Double(65.4321), otherwise osc will parsed it based on the input (eg. 65.4321 = f32).
  • see supported types below.
  • complete osc example /s_new "default with whitespace" 1002 'A' 12_i32 12_i64 -12 -12_i32 -12_i64 12.4533 1.234_f64 #2f14DF12 ~00110011 @12345:23 [12,20,true] %[10,20,30]


oscd follows OscType from rosc library

status types example notes
Int(i32) 1234 or 1234_i32
Long(i64) 1234_i64
Float(f32) 1234.32 or 1234.32_f32
Double(f64) 1234.25434_f64
String(String) "str goes here" wrapped in doulble quotes is needed
Bool(bool) true or false
Char(char) 'S' wrapped in single quote is needed
Blob(Vec<u8>) %[10,20,30] prefix with % separated by , number which is not u8 will be discarded
Time(OscTime) @123456789:20 prefix with @ separate fractional by : eg. @<seconds>:<fractional>
Color(OscColor) #2F14DF2A prefix with # followed by base16 #<red><green><blue><alpha>
Midi(OscMidiMessage) ~01F14FA4 prefix with ~ followed by base16 ~<port><status><data1><data2>
Array(OscArray) [10,20,true]
Nil Nil
Inf Inf

Building / Release

  • binary building with Github Action and supported following architectures
    • aarch64-linux

    • x86_64-linux

    • x86_64-macos

    • x86_64-windows

Bypass security settings. (OSX) (optional, in case of manual install binary file instead of cargo install oscd)

With each iteration of OS X from Mountain Lion onwards, Apple have made it progressively harder for users to access un-certificated downloaded applications/binary, such as those coming from the Open Source/Free Software community.

The problem typically manifests when trying to launch a newly downloaded application/binary whether directly or via the Dock. At the point of downloading a new app, the OS places it on a “quarantine list”. An alarming error message is displayed indicating the application is “damaged”, or from an unidentified developer, and has been prevented from running.

A standard workaround for a single application/binary is to launch using “Open” from the menu that pops up using Right-Click (or Ctrl-Click) on the application’s/binary's icon.
