Mango
MangoFix is a DSL which syntax is very similar to Objective-C，MangoFix is also an iOS App hotfix SDK. You can use MangoFix method replace any Objective-C method.
Example
#import "AppDelegate.h"
#import <MangoFix/MangoFix.h>
@implementation AppDelegate
- (BOOL)encryptPlainScirptToDocument{
NSError *outErr = nil;
BOOL writeResult = NO;
NSURL *scriptUrl = [[NSBundle mainBundle] URLForResource:@"demo" withExtension:@"mg"];

{

NSString *publicKey = [NSString stringWithContentsOfURL:publicKeyUrl encoding:NSUTF8StringEncoding error:&outErr];
if (outErr) goto err;
NSString *encryptedScriptString = [MFRSA encryptString:plainScriptString publicKey:publicKey];

Installation
CocoaPods
- Add
pod 'MangoFix'to your Podfile.
- Run
pod installorpod update. - Import
<MangoFix/MangoFix.h>
Usage
Objective-C
#import <MangoFix/MangoFix.h>exec Mango Script by [context evalMangoScriptWithSourceString:@""];
MFContext *context = [[MFContext alloc] init];
// exec mango file from network
[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://xxx/demo.mg"]] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
NSString *script = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
[context evalMangoScriptWithSourceString:script];
}];
// exec local mango file
NSString *sourcePath = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"mg"];
NSString *script = [NSString stringWithContentsOfFile:sourcePath encoding:NSUTF8StringEncoding error:nil];
[context evalMangoScriptWithSourceString:script];Mango

Mango Type usage
Mango support type as fllow:
void
equivalent to Objective-C `void`.
BOOL
equivalent to Objective-C `BOOL`.
uint
equivalent to Objective-C `unsigned char`、`unsigned short`、`unsigned int`、`unsigned long`、`unsigned long long`、`NSUInteger`.
int
equivalent to Objective-C `char`、`short`、`int`、`long`、`long long`、`NSInteger`.
double
equivalent to Objective-C `double`、`float`、`CGFloat`.
id
equivalent to Objective-C `id`.
OCClassName *
NSString *str = @"";
Block
Block blokc = ^id(id arg){};
Class
Class clazz = NSString.class();
struct
struct CGRect rect;// must add struct keyword before structure variables defined.
Pointer
Pointer ptr; // C pointer.
CFunction
CFunction<returnType,arg1Type,arg2Type,...> ptr = CFunction("c function name"); // CFunction.
