README
# The Swift logging framework.
`Atlantis` is an extremely powerful logging framework that I've created for everyday use, including enterprise development for aspiring start-ups or for rapid prototyping API's. It is **type agnostic**, meaning you can pass in anything from `strings` to custom`objects` that you yourself made... and it will basically **pretty print** all the values within that object or literally anything in general. It is made with exceptional readability and ease of use.
### Installation
Add this to your [podfile](https://cocoapods.org/)...
```
# for Swift 4.0
pod 'Atlantis', :git => 'https://github.com/aaronjsutton/Atlantis.git', :branch => 'swift-4-patch'
# for Swift 3.0
pod 'Atlantis'
# for Swift 2.3
pod 'Atlantis', :git => 'https://github.com/DrewKiino/Atlantis.git', :branch => 'swift2.3'
```
Then do a pod install, and voila!
## Unique Logs
This includes the stamp trace of the log's `date`, `source`, `function`, `line number`, as well as the **actual** `type` of the value.
**Note**: *The date's format goes by month, date, year, hour, then time of day.*
```swift
// You do not need to initialize this, the variable is initialized in file.
let log = Atlantis.Logger()
// Let's log some stuff
log.verbose("Hello, World!")
log.info("Hello, World!")
log.warning("Hello, World!")
log.debug("Hello, World!")
log.error("Hello, World!")
```
Which prints the following...
## Powerful Printing
`Atlantis` is built to `pretty print` literally everything.
### - `proper text alignment`
`Atlantis` automatically aligns its logs based on it's previous alignments. However you can change this configuration by setting this variable,
`Atlantis.Configuration.alignmentThreshold`
which defaults to `5`.
### - `optionals`
`Atlantis` will safely unwrap any optionals.
```swift
let doIExist: String? = nil
log.warning(doIExist)
// prints 'nil'
```
### - `empty strings`
`Atlantis` will visually print empty strings.
```swift
let emptyString: String = ""
log.warning(emptyString)
// prints ""
```
### - `native types`
``` swift
let string = "Hello, World"
let int = 123
let double = 12.3
let float = 12.3
let bool = true
// you can either log one value
log.debug(string)
// or all of them like so,
log.debug(string, int, double, float, bool)
// prints
"Hello, World" // first one
"Hello, World" // prints each with a new line
123
12.3
12.3
true
```
### - `arrays`
```swift
// array of ints
let numbers = [123, 1234, 12345]
log.debug(numbers)
// prints
[
123,
1234,
12345
]
```
```swift
// lets try arrays of arrays
let numberArray = [[1, 2, 3], [4, 5]]
log.debug(numberArray)
// prints
[
[
1,
2,
3
],
[
4,
5
]
]
```
### - `dictionaries`
```swift
// on to dictionaries...
let dictionary: [String: AnyObject] = [
"quote": "It is better to have loved, than to have never loved at all?"
]
log.debug(dictionary)
// prints
[
"quote": "It is better to have loved, than to have never loved at all?"
]
```
```swift
// how about NSDictionary types?
var dictionary = NSDictionary()
dictionary.updateValue("will this work?", key: "question")
log.debug(dictionary)
// prints
[
"question": "will this work?"
]
```
```swift
// say we got two response objects from the server,
// now both objects are the same but one of them has missing data...
responses.map { log.debug($0) }
// prints
{
"response": "Here is some data!",
"success" 200
},
{
"response": null,
"success" 200
}
// Atlantis will print all of the object's keys regardless of missing
// or empty values and will print null if need be.
```
### - `objects`
```swift
// now let's get to the fun part,
```
```swift
// native Foundation (ex: UIView, UIColor, etc.)
log.debug(UIColor())
// prints
```
```swift
// native NSObjects
public class Dog: NSObject {
var name = "Doug"
}
let dog = Dog()
log.debug(dog)
// prints
{
"name": "Doug"
}
```
``` swift
// But what about objects you created with no native subclasses?
public class CustomObject {
var id: Int = 123
var name: String = "Ben"
}
let customObject = CustomObject()
log.debug(customObject)
// prints
{
"id": 123,
"name": "Doug"
}
// Haha, no way?
```
```swift
// Alright, well how about custom objects with custom objects in them?
public class ParentObject {
var id: Int = 456
var name: String = "Tammy"
var customObject: CustomObject = CustomObject()
}
let parentObject = ParentObject()
log.debug(parentObject)
// prints
{
"id": 456,
"name": "Tammy"
"customObject": {
"id": 123,
"name": "Doug"
}
}
// That's right.
```
```swift
// Okay, custom objects with an array of custom objects. ;)
public class ParentObject {
var id: Int = 456
var name: String = "Tammy"
var customObjects: [CustomObject] = [CustomObject(), CustomObject()]
}
let parentObject = ParentObject()
log.debug(parentObject)
// prints
{
"id": 456,
"name": "Tammy"
"customObjects": [
{
"id": 123,
"name": "Doug"
},
{
"id": 123,
"name": "Doug"
}
]
}
```
```swift
// Not impressed?
let parentObject1 = ParentObject()
let parentObject2 = ParentObject() // one of its child has a dictionary
let parents: [ParentObject] = [parentObject1, parentObject2]
log.debug(parents)
// prints
[
{
"id": 456,
"name": "Tammy"
"customObjects": [
{
"id": 123,
"name": "Doug"
},
{
"id": 123,
"name": "Doug"
}
]
},
{
"id": 456,
"name": "Tammy"
"customObjects": [
{
"id": 123,
"name": "Doug"
},
{
"id": 123,
"name": "Doug"
"dictionary": [
"likes": "baseball",
"dislikes": "pad thai"
]
}
]
}
]
// Atlantis' logging is infinitely and ambiguously recursive,
// it supports almost all data types including arrays, dictionaries,
// and any objects within any objects. 👍🏼
```
### - `Structs`
```swift
// Great!! Now on to some more stand-alone but much needed types.
struct Struct {
var name: String = "Bob the Builder"
var skills: [String] = ["structures, buildings"]
}
log.debug(Struct())
// prints
{
"skills" : [
"structures, buildings"
],
"name" : "Bob the Builder"
}
```
### - `Enum`
```swift
enum ErrorType {
case Severe
case Moderate
case Casual
}
let type: ErrorType = .Severe
log.debug(type)
// prints
Severe
```
```swift
// one more example.
log.debug(ErrorType.Moderate)
log.debug(ErrorType.Casual)
// prints
Moderate
Casual
```
## Error Handling
`Atlantis` will print all errors like so,
```swift
Error: [ViewController.swift/viewDidLoad()/line:98]
{
"code" : 404,
"localizedDescription" : "The operation couldn’t be completed. (Hello, World! error 404.)",
"domain" : "Hello, World!",
"userInfo" : {
"error": "found"
"note": "syntax"
}
}
```
It will automatically parse the localized description, error code, domain, and user info from the `NSError` object.
```swift
Atlantis.Configuration.highlightsErrors // default false
```
By default, `Atlantis` will print all logs equally in white or in color if colored logging is enabled. However, if you enable error highlighting it will always highlight errors regardless of any set parameters.
```swift
Atlantis.Configuration.filteredErrorCodes
```
`Atlantis` has the ability to filter out errors based on their error code. For example, you have a method that sends requests to the network and you made it so it can only make one request at a time so it will always cancel the last request made. However, some APIs are out of our control and will send out errors without your permission.
Say you want to filter out error code `-1099 // offline error`,
```swift
Atlantis.Configuration.filteredErrorCodes.append(-1099)
// let's call a method that throws errors, however one of the
// errors is something we want to filter out.
method() { error in
log.error(error) // can either be error 404 or -1099?
}
// will only print the error if the error code is 404
```
Now, if the method throws a `-1099` error, `Atlantis` will will skip over it!
## .Tap
Tap is an `Atlantis` extension that allows you to print like how you would regularly do, but will return the value of the input.
```swift
func add(x: Int, _ y: Int) -> Int { return x + y }
let addXY = log.tap.debug(add(3, 5))
// prints 8 and assigns the value to addXY
```
Normal extensions such as ```.Verbose``` etc. are also under ```.Tap```
#### Compatible with ```Promises```
using [PromiseKit](https://github.com/mxcl/PromiseKit) more specifically...
```swift
func promise() -> Promise {
return Promise { fulfill, reject in
// blah blah
fulfill("Hello from server!")
}
}
promise()
.then { log.tap($0) }
.then { reply in
// blah blah
}
.catch { log.error($0) }
// prints "Hello from server!" while completing the promise.
```
Note that `.Tap` can only take in single inputs.
## Configuration
#### Levels
```swift
Atlantis.Configuration.logLevel // default .Verbose
```
The five log levels are: `Verbose`, `Info`, `Warning`, `Debug`, `Error`, and `None`, ordered by priority.
For example, if you set the log level to `Debug`, `Atlantis` will only print logs whose levels are `Debug` and `Error`.
Setting the log level to `.None` means `Atlantis` will skip all log execution. I recommend using this when the app is shift off to production.
#### Source Information
```swift
Atlantis.Configuration.showExtraInfo // default true
```
You can also hide the source details by setting this parameter to false.
#### Coloring
`Atlantis` is able to provide full color customization,
```swift
// colors
Atlantis.Configuration.hasColoredLogs // default false
Atlantis.Configuration.hasWhiteBackground // default false
Atlantis.Configuration.coloredLogLevels // default [.Verbose, .Info, .Warning, .Debug, .Error]
// using a Tuple initializer
Atlantis.Configuration.logColors.info = Atlantis.XCodeColor(fg: (Int, Int, Int)>, bg: <(Int, Int, Int)>)
// using UIColor setting only the foreground
Atlantis.Configuration.logColors.info = Atlantis.XCodeColor(fg: UIColor)
// or using UIColor setting both the foreground and background
Atlantis.Configuration.logColors.debug = Atlantis.XCodeColor(fg: UIColor, bg: UIColor)
```
By default, `Atlantis` doesn't print its logs in colors. if you want colors, you will need to set the configuration during launch.
However, for you to enable log colors you will have to first download the xcode package manager [Alcatraz](http://alcatraz.io/) and enable it inside xcode. Pull up the package manager afterwards and install [XCodeColors](https://github.com/robbiehanson/XcodeColors).
