objc-run is a shell script which compiles and executes Objective-C source code files. It integrates with CocoaPods.
It's perfect for small programming tasks you want to handle in Objective-C, that don't justify setting up a complete Xcode project, e.g. manipulating plist files. Think of it as CodeRunner without an user interface.
If you have homebrew installed, just run
brew install objc-run
Otherwise, download the objc-run shell script file and install it in a directory that's in your $PATH. Make sure the executable bit is set like this:
chmod u+x objc-run
Inside the Terminal, just enter:
objc-run myfile.m myparam1 myparam2
objc-run will attempt to compile myfile.m into an application called 'myfile'. If the file was successfully compiled, 'myfile' is launched and all remaining parameters are passed to it.
Once 'myfile' is done executing, it's removed.
Advanced usage (#!)
You can omit the explicit invocation of objc-run on the command line and launch it like this:
myfile.m myparam1 myparam2
Just insert this as first line in your .m file:
Make sure objc-run, or a link to it, is accessible from your $PATH.
Please note that as long as this line is present, it will produce an error when compiling it directly.
You can use CocoaPods modules with objc-run. Just include the contents of your podfile in a C-comment between 'podfile-start' and 'podfile-end', like this:
/* podfile-start platform :osx, '10.9' pod 'Barista' podfile-end */
There is a little test script that performs some basic checks.
$ ./test.bash Done $ echo $? 0
