A fork of Mecab, with support for both Japanese and Korean, organised as a Cocoapod and npm package for usage with iOS/macOS.
Specify this pod in your Podfile:
pod 'mecab-ko'pod updateAdd this npm package:
yarn add mecab-ko
# or:
npm install --save mecab-koNext, specify this pod in your Podfile:
pod 'mecab-ko', :podspec => '../node_modules/mecab-ko/mecab-ko.podspec'Don't forget to install the pods.
cd ios
pod updateImport the necessary mecab_ko headers into your class. Allocate and initialize a new Mecab object (specifying whether to use the Japanese or Korean dictionary – see links at bottom of this README to obtain these – via the DEFAULT_JAPANESE_RESOURCES_BUNDLE_NAME or DEFAULT_KOREAN_RESOURCES_BUNDLE_NAME constants) and then supply it a string to parse via the parseToNodeWithString method. It'll return an array of nodes that you can then manipulate as needed:
If you have use_frameworks! enabled in your Podfile, then you don't need to include a bridging header.
If you don't have it enabled (because you're using only static libraries), then add these imports to your bridging header to expose the Obj-C headers to the Swift runtime:
// LibMecabSample-macos-Bridging-Header.h
// Note how the module is `mecab-ko` in this Obj-C header but `mecab_ko` in Swift!
#import <mecab-ko/MecabObjC.h>
#import <mecab-ko/MecabNode.h>import mecab_ko // Omit this if you have `use_frameworks!` enabled in your Podfile.
// ...
let jpBundlePath = Bundle.main.path(forResource: DEFAULT_JAPANESE_RESOURCES_BUNDLE_NAME, ofType: "bundle")
let jpBundleResourcePath = Bundle.init(path: jpBundlePath!)!.resourcePath
let mecabJapanese: Mecab = Mecab.init(dicDirPath: jpBundleResourcePath!)
let japaneseNodes: [MecabNode]? = mecabJapanese.parseToNode(with: "すもももももももものうち")
japaneseNodes?.forEach({ node in print("[\(node.surface)] \(node.feature ?? "")") })// If use_frameworks! is on, you may have to write mecab_ko instead of mecab-ko.
// This is because Clang modules don't support hyphens:
// http://blog.cocoapods.org/Pod-Authors-Guide-to-CocoaPods-Frameworks/
#import <mecab-ko/MecabObjC.h>
#import <mecab-ko/MecabNode.h>
// ...
NSString *jpDicBundlePath = [[NSBundle mainBundle] pathForResource:DEFAULT_JAPANESE_RESOURCES_BUNDLE_NAME ofType:@"bundle"];
NSString *jpDicBundleResourcePath = [[NSBundle alloc] initWithPath:jpDicBundlePath].resourcePath;
self.mecab = [[Mecab alloc] initWithDicDirPath:jpDicBundleResourcePath];
NSArray<MecabNode *> results = [mecab parseToNodeWithString:@"すもももももももものうち"];This would give you the following result:
すもも: 名詞,一般,*,*,*,*,すもも,スモモ,スモモ
も: 助詞,係助詞,*,*,*,*,も,モ,モ
もも: 名詞,一般,*,*,*,*,もも,モモ,モモ
も: 助詞,係助詞,*,*,*,*,も,モ,モ
もも: 名詞,一般,*,*,*,*,もも,モモ,モモ
の: 助詞,連体化,*,*,*,*,の,ノ,ノ
うち: 名詞,非自立,副詞可能,*,*,*,うち,ウチ,ウチ
If you're planning to use this to present results to users, you'll probably need to write quite a bit of parsing code to put the nodes back together in a useful way since the nodes will be broken down into the smallest possible pieces.
