#About objc-run
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.
##Installation
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.
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:
#!/usr/bin/env objc-run
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.
##CocoaPods Integration
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
*/
Here is an example file from the Barista project modified for usage with objc-run.
There is a little test script that performs some basic checks.
Run:
$ ./test.bash
Done
$ echo $?
