I have a plugin I created for Eclipse that launches an external editor
using the IEditorLauncher interface. Apparently this interface changed in
3.0M4 to take an IPath object instead of an IFile object. How can I
convert the IPath into an IFile? I could easily convert IFile into IPath
however I would like to keep IFile since my code is already written around
it (ie. watching for file changes from other editors, opening an input
stream).

Probably the move to IPath is to support launching arbitrary files rather
than just files in the workspace, but I am speculating. An IPath is just a
high level data structure for manipulating paths, while an IFile is supposed
to represent a file resource in the workspace (although that is only the
case is the exists() method returns true).
To find a resource in the workspace who's actual location on disk is an
IPath use:
IWorkspaceRoot.findFilesForLocation(IPath location)
But if you are trying to launch the editor on a file that isn't in the
Eclipse workspace, you will need to be more careful.
Here are some utility functions that I have written and that I use:
public static IFile findFileResourceByLocation (String FileLocation)
{
IPath ResourcePath = new Path(FileLocation);
if (!ResourcePath.isAbsolute())
{
//this methods does not support relative paths
return null;
}
else
{
IFile[] Files =
getWorkspaceRoot().findFilesForLocation(ResourcePath);
return (Files.length > 0) ? Files[0] : null;
}
}
public static IFile[] findFileResourcesByLocation (String FileLocation)
{
IPath ResourcePath = new Path(FileLocation);
if (!ResourcePath.isAbsolute())
//this methods does not support relative paths
return new IFile[0];
else
return getWorkspaceRoot().findFilesForLocation(ResourcePath);
}
To call these with an IPath do something like (or change them to take
IPath's instead):
IPath p
findFileResourceByLocation(p.toOSString());
