24.2.6 *compile-file-pathname*, *compile-file-truename* Variable

Value Type:
The value of *compile-file-pathname* must always be a pathname or nil. The value of *compile-file-truename* must always be a physical pathname or nil.

Initial Value:

During a call to compile-file, *compile-file-pathname* is bound to the pathname denoted by the first argument to compile-file, merged against the defaults; that is, it is bound to (pathname (merge-pathnames input-file)). During the same time interval, *compile-file-truename* is bound to the truename of the file being compiled.

At other times, the value of these variables is nil.

If a break loop is entered while compile-file is ongoing, it is implementation-dependent whether these variables retain the values they had just prior to entering the break loop or whether they are bound to nil.

The consequences are unspecified if an attempt is made to assign or bind either of these variables.

Affected By:
The file system.
