#65: UTF-32 strings support ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | ------------------------+--------------------------------------------------- ABCL uses Java char[]s to represent its strings. However, the char type can only represent values in the BMP (Basic Multilingual Plane), because only the BMP can be represented using 16 bits. For supplementary characters (all Unicode chars outside the BMP), it uses a pair of surrogate characters (UTF-16). Common Lisp programs don't expect this and need strings to be represented using complete characters. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/65> armedbear <http://common-lisp.net/project/armedbear> armedbear

But we claim that ABCL will be ANSI first > > and foremost, so I guess we have to pay attention here… I should mention that I use routinely logical pathnames, and they work very well, on all implementations that conformantly implement them. That means that all my logical pathnames are always upcase letters, and no special symbols (apart from an occasional dash). I understand that using implementation dependant syntax (special characters, lower-case, mixed-case) in logical pathnames can lead to surprises, but I avoid them. Now, it's not a question of extinct file systems. You still have to deal with at least two different major syntaxes: POSIX and MS-Windows/MS-DOS. I just cannot use in programs that will have to run on both Linux or MacOSX and MS-Windows physical pathname literals, because they don't use the same syntax. On the other hand, #P"HOME:SRC;LISP;EXAMPLE.LISP" can be translated to either #P"C:\\Users Files\\Pascal\\src\\lisp\\example.lisp" or #P"/home/pjb/src/lisp/example.lisp" portably on these targets. The point for an implementation is to know what it's targets are, and to implement proper behavior when translating and merging logical pathnames. You must be careful when merging logical pathnames with physical pathnames, notably when it's done in make-pathname: the :case parameter must have effect only on the new strings, not on the :defaults parameter. > > I suppose there is no definition of "customary case", huh?

Does Java provide its own file system, or does it map to the host file system? Notice that logical pathnames don't have to be able to represent all the physical pathnames, without an explicit translation. If you have a file system that is case sensitive, then you may write: (setf (logical-pathname-translations "APP") (list (list #P"APP:EXAMPLE;FILE.LISP" #P"/MyApp/Example/File.lisp") (list #P"APP:EXAMPLE;ANOTHER-FILE.LISP" #P"/MyApp/Example/AnotherFile.lisp") (list #P"APP:EXAMPLE;*.DATA" #P"/MyApp/Example/*.appdata") (list #P"APP:EXAMPLE;SOME-MODULE.*" #P"/MyApp/Example/SomeBigModule.*") (list #P"APP:APP.CONFIGURATION" #P"/MyApp/.config") (list #P"APP:CUSTOMARY;**;*" #P"/MyApp;**;*") (list #P"APP:CUSTOMARY;**;*.*" #P"/MyApp;**;*.*"))) to be able to access to files with strange physical names. The question indeed is to decide what is the customary case. You can choose uppercase or you can choose lowercase. This matters only for file systems that are case sensitive, but even file systems that are not case sensitive, such as MS-DOS, have a prefered way to display the names. > > Lacking a more precise definition, I would then advocate that we declare > > lowercase to be the customary case across UNIX, OSX, and Windows for > > ABCL, patching our behavior accordingly.
