Procedure Summary
BaseName(STRING): STRING

          Calculates the basename of pathname path.
Decode(ARRAY OF CHAR): STRING

          Convert a system-specific sequence of bytes path representing a file path into a string instance.
DirName(STRING): STRING

          Calculates the directory name of pathname path.
Encode(STRING): CharsLatin1

          Encode the file path or command path as a system-specific sequence of bytes.
SplitExt(STRING, VAR STRING, VAR STRING)

          Splits the pathname path into a pair `(root, ext)' such that `concat(root,ext) = path'.

Procedure Detail

BaseName

PROCEDURE BaseName(path: STRING): STRING

Calculates the basename of pathname path. The basename is the last pathname component of path. It never contains a slash. If path ends with a slash, then the basename is the empty string. If path does not contain a slash, then the basename equals path.


Decode

PROCEDURE Decode(path: ARRAY OF CHAR): STRING

Convert a system-specific sequence of bytes path representing a file path into a string instance. This is the inverse of Encode.


DirName

PROCEDURE DirName(path: STRING): STRING

Calculates the directory name of pathname path.


Encode

PROCEDURE Encode(path: STRING): CharsLatin1

Encode the file path or command path as a system-specific sequence of bytes.

The default implementation returns a string with all character codes above `0FFX' replaced with the character `_'. That is, non ISO Latin1 characters are discarded. For instances of Object.String8, it is the identity operation.


SplitExt

PROCEDURE SplitExt(path: STRING; 
                   VAR root: STRING; 
                   VAR ext: STRING)

Splits the pathname path into a pair `(root, ext)' such that `concat(root,ext) = path'. The extension ext is empty or begins with a period and contains at most one period. The extension string does not contain a slash character.
