**Lightweight NodeJS Logging**
Overview
=======
# Scribe.js
Unlike many of the libraries out there, Scribe.js allows logging on multiple files and is divided into folders by date. And it is possibly the easiest logging you can implement. And it does everything you need a basic logger to do.
- Save messages into log files organized by user, date, and type
- Print messages into console using colors indicating level of importance
Output Methods (Web | Console | File)
=======
Method#Web - Select Date

## Getting Started
Install the module with: `npm install scribe-js`
How to use Scribe.js
=======
Using Sribe is as simple as putting the contents of the Scribe folder into your root NodeJS folder. Note: What I am about to show you is the simplest way to use Scribe.js. Since this library (if you can even call it that), is not insave at all, and it should be very easy to adjust to your liking.
1. Make a Scribe directory
----
```javascript
var scribe = require('scribe');
```
\root
\node_modules
\views
\controllers
\bunchOfOtherFolder...
\scribe <--- Make a folder named "scribe"
app.js
```
2. Add Scribe into this folder
----
```
\scribe <--- Copy the contents of the "src" folder (which you get from this repo) into "scribe".
```
4. Install the required modules
----
```bat
npm install colors
npm install moment
npm install mkdirp
npm install callsite
npm install express // if you want to enable the visual web view
```
5. Logging with Scribe
----
```js
var scribe = require('./scribe');
// Configuration
// --------------
scribe.configure(function(){
scribe.set('app', 'MY_APP_NAME'); // NOTE Best way learn about these settings is
scribe.set('logPath', './scribe'); // Doublecheck // them out for yourself.
scribe.set('defaultTag', 'DEFAULT_TAG');
scribe.set('divider', ':::');
scribe.set('identation', 5); // Identation before console messages
## Documentation
_(Coming soon)_
scribe.set('maxTagLength', 30); // Any tags that have a length greather than
// 30 characters will be ignored
## Examples
_(Coming soon)_
scribe.set('mainUser', 'root'); // Username of the account which is running
// the NodeJS server
});
## Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).
// Create Loggers
// --------------
scribe.addLogger("log", true , true, 'green'); // (name, save to file, print to console,
scribe.addLogger('realtime', true, true, 'underline'); // tag color)
scribe.addLogger('high', true, true, 'magenta');
scribe.addLogger('normal', true, true, 'white');
scribe.addLogger('low', true, true, 'grey');
scribe.addLogger('info', true, true, 'cyan');
## Release History
_(Nothing yet)_
// Express.js
// WARNING: ExpressJS must be installed for this to work
// You also need to start an ExpressJS server in order for
// this to work.
// --------------
app.use(scribe.express.logger(function(req, res){ // Express.js access log
return true; // Filter out any Express messages
}));
// Control Panel
// WARNING: ExpressJS must be installed for this to work
// You also need to start an ExpressJS server in order for
// this to work.
// --------------
app.get('/log', scribe.express.controlPanel()); // Enable web control panel
// Basic logging
// --------------
console.log("[Tagname] Your message"); // [Tagname] Your message
console.realtime("[Tagname] Your message"); // [Tagname] Your message
console.high("[Tagname] Your message "); // [Tagname] Your message
console.normal("[Tagname][]Your message"); // [Tagname] []Your message
console.low("[Tagname]Your message"); // [Tagname] Your message
// Tagging function
// ----------------
console.t("Tagname").log("Your message"); // [Tagname] Your message
console.t("Tagname").log("Your message"); // [Tagname] Your message
console.t("Tagname").log("Your message"); // [Tagname] Your message
// Force use default tag
// ---------------------
console.t().log("Your message"); // [MY_APP_NAME] Your message
// Pass in file name
// -----------------
console.f(__filename).log("Your message"); // [file.js] Your message
// Auto tagging
// ------------
console.log("Your message"); // [invokedFrom.js:25] Your message
// Tag Scoping
// -----------
(function(console){
console.info("yeeha"); // [scoped-tag] yeeha
console.log("yeeha"); // [scoped-tag] yeeha
})(console.t('scoped-tag'));
```
6. Experimental
----
```js
// Simple Testing
// --------------
console.test("Test name").should(5).be(5); // Pretty printed test results
```
