Using Clang Static Analyzer from within Xcode

Question

Since there is no Xcode script variable for "current project directory," how can you create a script menu item to run the Clang Static Analyzer on your current project from Xcode?

Answer 1

From the XCode script menu item, "Edit User Scripts" enter the following script:

#!/bin/bash
result=$( osascript << END
tell application "Xcode"
 tell active project document
  set projectPath to path as string
 end tell 
end tell 
return projectPath
END
)

cd "$result"

/Developer/clangchecker/scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator3.0

Obviously, you will need to adjust the path to your install of Clang, and adjust to the version of the SDK you are using.

Remember to do a "Clean All" immediately before using scan-build, or the results may be incomplete.

Answer 2

FYI, Xcode 3.2 (Snow Leopard only I believe) includes the Clang Static Analyzer in the "Build and Analyze" menu option.

One downside of Xcode 3.2 (aside from it only working on Snow Leopard) is that the v2.x Simulators don't seem to work - in fact, I've seen posts indicating that v2.x builds are not supported at all.
