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 = 127.0.0.1

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

Usage

• 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]

Types

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

Development

• cargo run

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.
