示例1: GetDefinition

fn, args, err := c.prepare(&a.CompleteAtArgs)
if err != nil {
return err
}

out, oute, err := RunClang(a.Location.File.Contents, args...)
if len(out) == 0 {
if err != nil {
return err
} else {

}

}示例2: Visibility
// Returns the RegionSet visible from the given source code location.
// Note that it only uses '{' and '}' to deduce scopes, and further
// processing is likely needed depending on language specifics.

// source code parseable.
