Support for code piped through stdin

[franciscolourenco]

This would allow any transpiler to be used on the fly without extra files or configuration.

Examples:

• babel app.es6 | node-iron
• coffee -p app.coffee | node-iron
• etc...

Just thought about... But how we should handle Ctrl+r code reloading?

[franciscolourenco]

Not possible I guess. Other way of achieving the same is have an option to pass a command to get the code. Having the command, then you could just run the command again.

iron-node --execute 'coffee -p app.coffee'

But I like this pipe idea 😄 Maybe we can access piped terminal commandline text to repeat the preprocess.

[franciscolourenco]

The place where terminal history is saved varies depending on the shell :/

Yes I know and it seems there is no module out there solving this...

I succesfuly got access to stdin data at

iron-node/bin/run.js

Line 17 in e844eac

console.log("data", chunk);

But having trouble to access stdin at the main process module.

iron-node/app/index.js

Line 11 in e844eac

process.stdin.on('data', function(chunk) {

I Created a test script at

iron-node/package.json

Line 16 in e844eac

"pipe-test": "echo \"var i = 0; debugger;\" | node bin/run.js",

pipe-test

May be someone can help out?

Sorry @aristidesfl this cannot work native on Microsoft Windows. We can only ugly work around when we use a temporary file to share piped result with electron.exe. So far I cannot see super advantages instead of using a simple bash script. Unless there are strong requests to add piped stdin support I will not implement that.

[franciscolourenco]

It wouldn't matter how it is implemented as long as the complexity would be hidden from the user :) That way the simple "bash script" only had to be written once in node-iron in the form of pipe support.

I want give it a try, but should we store the tempfile in the working directory? it has an impact on later required files.

@aristidesfl could you please test if this works for you by installing from repo?

git clone https://github.com/s-a/iron-node.git
cd iron-node
npm install -g
echo var i = 0;debugger; | iron-node

This work fine for me. I will publish a new version in a few minutes.
