objc2swift is an open source project, aiming to create an automatic Objective-C -> Swift converter (or at least an useful helper for human).
The project contains an auto-generated Objective-C parser, generated by ANTLR v4 with the grammer ObjC.g4.
What it does
- converts
@interface Hogetoclass Hoge {} - ... that's all for now!
Setup
1. Install Scala
$ brew install scala
2. Install ANTLR v4
install:
$ cd /usr/local/lib
$ curl -O http://www.antlr.org/download/antlr-4.5-complete.jar
add classpath and aliases:
$ export CLASSPATH=".:/usr/local/lib/antlr-4.5-complete.jar:$CLASSPATH"
$ alias antlr4='java -Xmx500M -cp "/usr/local/lib/antlr-4.5-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
$ alias grun='java org.antlr.v4.runtime.misc.TestRig'
for test, compile the ObjC parser and run the TestRig:
$ cd gen/
$ javac ObjC*.java
$ grun ObjC translation_unit ../sample/sample.h -gui
you should see something like this:
See Getting Started with ANTLR v4 for more detail.
3. Import project and run!
Set src/ for source directory, gen/ for generated source directory. Pass sample/sample.h as the program argument, and run!
class A : NSObject {
}
Got this? Cool! You've successfully converted the sample Obj-C code to Swift!
@interface A : NSObject
@end
