humbug

humbug

Debug inline state with a streaming repl.

example

open a repl for some nested state

var humbug = require('humbug');

(function (x) {
    var z = 33;
    (function (w) {
        var y = 222222;
        eval(humbug);
    })(1111);
})(5555)

 $ node example/debug.js 
> x
5555
> y
222222
> z * 1000
33000
> 

stream a repl

var humbug = require('humbug');
var fs = require('fs');

(function (x) {
    var z = 33;
    (function (w) {
        var y = 222222;
        fs.createReadStream('in.txt')
            .pipe(eval(humbug))
            .pipe(fs.createWriteStream('out.txt'))
        ;
    })(1111);
})(5555)

input file:

x
y + z

output file:

> 5555
> 222255
> 

methods

There are no methods! This module just exports a string that you can eval() whenever you want to make a new repl. This is the only way I can think of to easily get at local variables.

var humbug = require('humbug')

eval(humbug)

Create a repl at the present context.

Returns a readable/writable repl stream so you can pipe this over the network or to a browser.

If you don't .pipe() to the repl stream by the nextTick, process.stdin will be used.

If you don't .pipe() from the repl stream by the nextTick, process.stdout will be used.

install

With npm do:

npm install humbug
