Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

gulp-osc

v0.0.2

Published

OSC with gulp.

Readme

gulp-osc

Using OSC with gulp!

Usage

osc.listen()

Run task when OSC message received.

var osc = require('gulp-osc');
osc.listen("/message",10000,function(msg,lock){
    lock(
        gulp.src("*.txt")
            .pipe(gulp.dest("dest"));
    );
});

What is lock?

lock() means "Do not call this callback until ended this task.".

If receive same OSC message continuously in a short period of time.
Might your task is not finished.
That will be a fatal problem (at least for me).

At that time, write task inner lock function.
Then, If gulp-osc received new OSC message during run task.
gulp-osc calling callback function after current task end.

OSC送られてきたら処理をしたいという時に使います。

lock() を使うと、その中で走らせた gulp タスクが終わるまで
コールバックを呼ばなくなるので、タスクが多重に走ることを防ぐ事が出来ます。

また、lock の第2引数に false を指定すると
ロック中に新しいメッセージが来てもそのメッセージは無視します。

osc()

Send OSC message.

引数で指定した設定で OSC を送信します。
var osc = require('gulp-osc');
gulp.src("test.txt")
    .pipe(osc("/hoge ,i 1",10000,"127.0.0.1"));

or

gulp.src("test.txt")
    .pipe(
    	osc({
    		"message"     : "/hoge ,i 1",
    		"sendPort"    : 10000,
    		"sendAddress" : "127.0.0.1"
    	})
    );

osc.sendSrcPath()

Send src path.

pipe に入ってきたファイル名を送ります。
filter 関数を指定することで、ファイル名を加工する事もできます。
var osc = require('gulp-osc');
gulp.src("*.txt")
    .pipe(osc.sendSrcPath(
    	"/hoge",
    	12345,
    	"localhost",
    	function(path){
			return path.substr( path.lastIndexOf("/")+1, path.length );
		}
	});

or

gulp.src("*.txt")
    .pipe(osc.sendSrcPath({
		"oscAddress"  : "/hoge",
		"sendPort"    : 12345,
		"sendAddress" : "localhost",
		"filter"      : function(path){
			return path.substr( path.lastIndexOf("/")+1, path.length );
		}
	});

osc.through2()

Build OSCMessage with through2 by yourself.

完全に自分で好き放題やりたいというあなたに。
through2 経由でいろいろいじれます。

第1引数に through2.obj 関数への参照
第2引数に oscMessage が渡されるので
transform なり flush なりの中で oscMessage.addArgument すれば
その内容で送信をする事ができます。
var osc = require('gulp-osc');
gulp.src("*.txt")
    .pipe(osc.through2(
    	function(through2,oscMessage){
    		return through2(
    			function transform(file,encoding,callback){
    				// for example.
    				oscMessage.addArgument("s",file.path);
    				this.push(file);
    				callback();
    			},
    			function flush(callback){
    				// do something.
    				callback();
    			}
    		);
    	},
    	{
			"oscAddress"  : "/hoge",
			"sendPort"    : 12345,
			"sendAddress" : "localhost"
		}
	});
