GlobalExtendedHeader0.1.0

Defaults to all module properties rendered as either Pcf or the format specified on the command line.

This method is used to convert the values of string interpolation expressions to strings.

This method is the complement of the ?? operator and the equivalent of an Option type's map and flatMap methods.

Throws if a property with this name does not exist.

Returns null if a property with this name does not exist.

Throws if no such path exists.

For example, if module mod1 has path /dir1/mod1.pkl, and module mod2 has path /dir1/dir2/dir3/mod2.pkl, then mod1.relativePathTo(mod2) will return List("dir2", "dir3").

A common use case is to compute the directory path between a template located at the root of a hierarchy (say rootModule.pkl) and the currently evaluated module (accessible via the module keyword):

import "rootModule.pkl" // self-import
path = rootModule.relativePathTo(module)

Procedure:

1. Replace the 8 byte checksum fields with ASCII spaces (0x20).
2. Sum every byte in the header block.
3. Encode as a 6 digit octal number, followed by a NUL and then a space.
4. Replace the 8 byte checksum field with the encoded checksum.

• This impl reuses the blanked checksum header and replaces the first 7 bytes with the sum.
