On MS-DOS/MS-Windows, file names are case-insensitive, so Emacs by default ignores letter-case in file names during completion. +@node ls in Lisp +@section Emulation of @code{ls} on MS-Windows +@cindex Dired, and MS-Windows/MS-DOS +@cindex @code{ls} emulation + + Dired normally uses the external program @code{ls} (or its close +work-alike) to produce the directory listing displayed in Dired +buffers (@pxref{Dired}). However, MS-Windows and MS-DOS systems don't +come with such a program, although several ports of @sc{gnu} @code{ls} +are available. Therefore, Emacs on those systems @emph{emulates} +@code{ls} in Lisp, by using the @file{ls-lisp.el} package. While +@file{ls-lisp.el} provides a reasonably full emulation of @code{ls}, +there are some options and features peculiar to that emulation; they +are described in this section. + + The @code{ls} emulation supports many of the @code{ls} switches, but +it doesn't support all of them. Here's the list of the switches it +does support: @option{-A}, @option{-a}, @option{-B}, @option{-C}, +@option{-c}, @option{-i}, @option{-G}, @option{-g}, @option{-R}, +@option{-r}, @option{-S}, @option{-s}, @option{-t}, @option{-U}, +@option{-u}, and @option{-X}. The @option{-F} switch is partially +supported (it appends the character that classifies the file, but does +not prevent symlink following). + +@vindex ls-lisp-use-insert-directory-program + On MS-Windows and MS-DOS, @file{ls-lisp.el} is preloaded when Emacs +is built, so the Lisp emulation of @code{ls} is always used on those +platforms. If you have a ported @code{ls}, setting +@code{ls-lisp-use-insert-directory-program} to a non-@code{nil} value +will revert to using an external program named by the variable +@code{insert-directory-program}. + +@vindex ls-lisp-ignore-case + By default, @file{ls-lisp.el} uses a case-sensitive sort order for +the directory listing it produces; this is so the listing looks the +same as on other platforms. If you wish that the files be sorted in +case-insensitive order, set the variable @code{ls-lisp-ignore-case} to +a non-@code{nil} value. + +@vindex ls-lisp-dirs-first + By default, files and subdirectories are sorted together, to emulate +the behavior of @code{ls}. However, native MS-Windows/MS-DOS file +managers list the directories before the files; if you want that +behavior, customize the option @code{ls-lisp-dirs-first} to a +non-@code{nil} value. + +@vindex ls-lisp-verbosity + The variable @code{ls-lisp-verbosity} controls the file attributes +that @file{ls-lisp.el} displays. The value should be a list that +contains one or more of the symbols @code{links}, @code{uid}, and +@code{gid}. @code{links} means display the count of different file +names that are associated with (a.k.a.@: @dfn{links to}) the file's +data. @code{uid} means display the numerical identifier of the user +who owns the file. @code{gid} means display the numerical identifier +of the file owner's group. The default value is @code{(links uid gid)} +i.e.@: all the 3 optional attributes are displayed. + +@vindex ls-lisp-emulation + The variable @code{ls-lisp-emulation} controls the flavour of the +@code{ls} emulation by setting the defaults for the 3 options +described above: @code{ls-lisp-ignore-case}, +@code{ls-lisp-dirs-first}, and @code{ls-lisp-verbosity}. The value of +this option can be one of the following symbols: + +@table @code +@item GNU +@itemx nil +Emulate @sc{gnu} systems; this is the default. This sets +@code{ls-lisp-ignore-case} and @code{ls-lisp-dirs-first} to +@code{nil}, and @code{ls-lisp-verbosity} to @code{(links uid gid)}. +@item UNIX +Emulate Unix systems. Like @code{GNU}, but sets +@code{ls-lisp-verbosity} to @code{(links uid)}. +@item MacOS +Emulate MacOS. Sets @code{ls-lisp-ignore-case} to @code{t}, and +@code{ls-lisp-dirs-first} and @code{ls-lisp-verbosity} to @code{nil}. +@item MS-Windows +Emulate MS-Windows. Sets @code{ls-lisp-ignore-case} and +@code{ls-lisp-dirs-first} to @code{t}, and @code{ls-lisp-verbosity} to +@code{(links)} on Windows NT/2K/XP/2K3 and to @code{nil} on Windows 9X. +Note that the default emulation is @emph{not} @code{MS-Windows}, even +on Windows, since many users of Emacs on those platforms prefer the +@sc{gnu} defaults. +@end table + +@noindent +Any other value of @code{ls-lisp-emulation} means the same as +@code{GNU}. Note that this option needs to be set @emph{before} +@file{ls-lisp.el} is loaded, which means that on MS-Windows and MS-DOS +you will have to set the value from your @file{.emacs} file and then +restart Emacs, since @file{ls-lisp.el} is preloaded. + +@vindex ls-lisp-support-shell-wildcards + The variable @code{ls-lisp-support-shell-wildcards} controls how +file-name patterns are supported: if it is non-@code{nil} (the +default), they are treated as shell-style wildcards; otherwise they +are treated as Emacs regular expressions. + @node Windows HOME @section HOME Directory on MS-Windows @cindex @code{HOME} directory on MS-Windows -- 2.39.2
