> Debug node applications with tmp files.

Motivation

While trying to understand how a daemon application worked, I wasn't able to debug
with node-inspector very easily. The daemon also detached io streams, making
console log/error a non starter. I ended up writing to a tmp file and decided to
publish a module around it.

Here's some sample output that was written to a file:

Installing

It's recommended to install tmp-debug globally:

``bash
npm install -g tmp-debug
`

Usage

$3

`javascript
var tmpDebug = require('tmp-debug')('log.txt');

tmpDebug.logStackTrace();
tmpDebug.log('foo');
function someFn() {
tmpDebug.logArgs(arguments);
}
someFn();
`

$3

tmp-debug ./some/directory

All javascript files found in the directory will be instrumented with
tmpDebug.logArgs(arguments); in every function found therein.

Viewing

Once you're logging, you can view the file output in the following ways:

* tail -f /tmp/log.txt
* less -R /tmp/log.txt

Configuring

Place .tmpdebugrc on your path.

$3

`json
{
"enabled": true,
"filters": [
{
"file": "optional/path/some-file.js",
"functionName": "someFunctionName",
"line": 50,
"column": 30
}
],
"outputDepth": 3
}
`

#### filters

An array of filter objects that control what gets logged.

* file filters files that end with it's value.
* functionName filters functions that end with it's value.
* line filters functions that occor on this line.
* column filters functions that occur on this column.

#### outputDepth

An integer controlling how many levels deep inspected objects will be logged.
