# BRLOptionParser [![Build Status][1]][2]
A short wrapper for [getopt_long(3)][3] (and getopt_long_only(3)).
[1]: https://img.shields.io/travis/stephencelis/BRLOptionParser.svg?style=flat
[2]: https://travis-ci.org/stephencelis/BRLOptionParser
[3]: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/getopt_long.3.html
## Install
With [CocoaPods][4]:
``` rb
# Podfile
pod 'BRLOptionParser', '~> 0.3.1'
```
[4]: http://cocoapods.org
## Example
``` objc
// main.m
#import <BRLOptionParser/BRLOptionParser.h>
int main(int argc, const char * argv[])
{
@autoreleasepool {
NSString *name = @"world";
BOOL verbose = NO;
BRLOptionParser *options = [BRLOptionParser new];
[options setBanner:@"usage: %s [-n <name>] [-vh]", argv[0]];
[options addOption:"name" flag:'n' description:@"Your name" argument:&name];
[options addSeparator];
[options addOption:"verbose" flag:'v' description:nil value:&verbose];
__weak typeof(options) weakOptions = options;
[options addOption:"help" flag:'h' description:@"Show this message" block:^{
printf("%s", [[weakOptions description] UTF8String]);
exit(EXIT_SUCCESS);
}];
NSError *error = nil;
if (![options parseArgc:argc argv:argv error:&error]) {
const char * message = error.localizedDescription.UTF8String;
fprintf(stderr, "%s: %s\n", argv[0], message);
exit(EXIT_FAILURE);
}
if (verbose) {
fprintf(stderr, "(Preparing to say hello...)\n");
}
printf("Hello, %s!\n", name.UTF8String);
}
return EXIT_SUCCESS;
}
```
In practice:
```
$ hello
Hello, world!
$ hello -h
usage: hello [-n <name>] [-vh]
-n, --name Your name
-v, --verbose
-h, --help Show this message
$ hello -n
hello: option `-n' requires an argument
$ hello --name Stephen
Hello, Stephen!
$ hello -vngoodbye
(Preparing to say hello...)
Hello, goodbye!
$ hello --goodbye
hello: unrecognized option `--goodbye'
```
