-;;; Generalized mailcap parsing and access routines
-;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
-;;;
-;;; Data structures
-;;; ---------------
-;;; The mailcap structure is an assoc list of assoc lists.
-;;; 1st assoc list is keyed on the major content-type
-;;; 2nd assoc list is keyed on the minor content-type (which can be a regexp)
-;;;
-;;; Which looks like:
-;;; -----------------
-;;; (
-;;; ("application"
-;;; ("postscript" . <info>)
-;;; )
-;;; ("text"
-;;; ("plain" . <info>)
-;;; )
-;;; )
-;;;
-;;; Where <info> is another assoc list of the various information
-;;; related to the mailcap RFC. This is keyed on the lowercase
-;;; attribute name (viewer, test, etc). This looks like:
-;;; (("viewer" . viewerinfo)
-;;; ("test" . testinfo)
-;;; ("xxxx" . "string")
-;;; )
-;;;
-;;; Where viewerinfo specifies how the content-type is viewed. Can be
-;;; a string, in which case it is run through a shell, with
-;;; appropriate parameters, or a symbol, in which case the symbol is
-;;; funcall'd, with the buffer as an argument.
-;;;
-;;; testinfo is a list of strings, or nil. If nil, it means the
-;;; viewer specified is always valid. If it is a list of strings,
-;;; these are used to determine whether a viewer passes the 'test' or
-;;; not.
-;;;
-;;; The main interface to this code is:
-;;;
-;;; To set everything up:
-;;;
-;;; (mm-parse-mailcaps [path])
-;;;
-;;; Where PATH is a unix-style path specification (: separated list
-;;; of strings). If PATH is nil, the environment variable MAILCAPS
-;;; will be consulted. If there is no environment variable, then a
-;;; default list of paths is used.
-;;;
-;;; To retrieve the information:
-;;; (mm-mime-info st [nd] [request])
-;;;
-;;; Where st and nd are positions in a buffer that contain the
-;;; content-type header information of a mail/news/whatever message.
-;;; st can optionally be a string that contains the content-type
-;;; information.
-;;;
-;;; Third argument REQUEST specifies what information to return. If
-;;; it is nil or the empty string, the viewer (second field of the
-;;; mailcap entry) will be returned. If it is a string, then the
-;;; mailcap field corresponding to that string will be returned
-;;; (print, description, whatever). If a number, then all the
-;;; information for this specific viewer is returned.
-;;;
-;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
-;;; Variables, etc

-This package contains a beta version of Gnus. The lisp directory
-contains the source lisp files, and the texi directory contains a
-draft of the Gnus info pages.
-
-To use Gnus you first have to unpack the files, which you've obviously
-done, because you are reading this.
-
-You should definitely byte-compile the source files. To do that, you
-can simply say "./configure; make" in this directory. If you are
-using XEmacs, you *must* say "make EMACS=xemacs". In that case you
-may also want to pull down the package of nice glyphs from
-<URL:http://www.gnus.org/etc.tar.gz>. It should be installed
-into the "gnus-5.4.53/etc" directory.
-
-Then you have to tell Emacs where Gnus is. You might put something
-like
-
- (setq load-path (cons (expand-file-name "~/gnus-5.4.53/lisp") load-path))
-
-in your .emacs file, or wherever you keep such things.
-
-To enable reading the Gnus manual, you could say something like:
-
- (setq Info-default-directory-list
- (cons "~/gnus-5.4.53/texi" Info-default-directory-list))
-
-Note that Gnus and GNUS can't coexist in a single Emacs. They both use
-the same function and variable names. If you have been running GNUS
-in your Emacs, you should probably exit that Emacs and start a new one
-to fire up Gnus.
-
-Gnus does absolutely not work with anything older than Emacs 19.33 or
-XEmacs 19.14. So you definitely need a new Emacs.
-
-Then you do a `M-x gnus', and everything should... uhm... it should
-work, but it might not. Set `debug-on-error' to t, and mail me the
-backtraces, or, better yet, find out why Gnus does something wrong,
-fix it, and send me the diffs. :-)
-
-There are four main things I want your help and input on:
-
-1) Startup. Does everything go smoothly, and why not?
-
-2) Any errors while you read news normally?
-
-3) Any errors if you do anything abnormal?
-
-4) Features you do not like, or do like, but would like to tweak a
- bit, and features you would like to see.
-
-Send any comments and all your bug fixes/complaints to
-`bugs@gnus.org'.

-@section Introduction
-
-This library allows customization of @dfn{user options}. Currently two
-types of user options are supported, namely @dfn{variables} and
-@dfn{faces}. Each user option can have four different values
-simultaneously:
-@table @dfn
-@item factory setting
-The value specified by the programmer.
-@item saved value
-The value saved by the user as the default for this variable. This
-overwrites the factory setting when starting a new emacs.
-@item current value
-The value used by Emacs. This will not be remembered next time you
-run Emacs.
-@item widget value
-The value entered by the user in a customization buffer, but not yet
-applied.
-@end table
-
-Variables also have a @dfn{type}, which specifies what kind of values
-the variable can hold, and how the value is presented in a customization
-buffer. By default a variable can hold any valid expression, but the
-programmer can specify a more limited type when declaring the variable.
-
-The user options are organized in a number of @dfn{groups}. Each group
-can contain a number user options, as well as other groups. The groups
-allows the user to concentrate on a specific part of emacs.
-
-@node User Commands, The Customization Buffer, Introduction, Top
-@comment node-name, next, previous, up
-@section User Commands
-
-The following commands will create a customization buffer:
-
-@table @code
-@item customize
-Create a customization buffer containing a specific group, by default
-the @code{emacs} group.
-
-@item customize-variable
-Create a customization buffer containing a single variable.
-
-@item customize-face
-Create a customization buffer containing a single face.
-
-@item customize-apropos
-Create a customization buffer containing all variables, faces, and
-groups that match a user specified regular expression.
-@end table
-
-@node The Customization Buffer, Declarations, User Commands, Top
-@comment node-name, next, previous, up
-@section The Customization Buffer.
-
-The customization buffer allows the user to make temporary or permanent
-changes to how specific aspects of emacs works, by setting and editing
-user options.
-
-The customization buffer contains three types of text:
-
-@table @dfn
-@item informative text
-where the normal editing commands are disabled.
-
-@item editable fields
-where you can edit with the usual emacs commands. Editable fields are
-usually displayed with a grey background if your terminal supports
-colors, or an italic font otherwise.
-
-@item buttons
-which can be activated by either pressing the @kbd{@key{ret}} while
-point is located on the text, or pushing @kbd{mouse-2} while the mouse
-pointer is above the tex. Buttons are usually displayed in a bold
-font.
-@end table
-
-You can move to the next the next editable field or button by pressing
-@kbd{@key{tab}} or the previous with @kbd{M-@key{tab}}. Some buttons
-have a small helpful message about their purpose, which will be
-displayed when you move to it with the @key{tab} key.
-
-The buffer is divided into three part, an introductory text, a list of
-customization options, and a line of customization buttons. Each part
-will be described in the following.
-

-@subsection The Introductory Text
-
-The start of the buffer contains a short explanation of what it is, and
-how to get help. It will typically look like this:
-
-@example
-This is a customization buffer.
-Push RET or click mouse-2 on the word _help_ for more information.
-@end example
-
-Rather boring. It is mostly just informative text, but the word
-@samp{help} is a button that will bring up this document when
-activated.
-
-@node The Customization Options, The Variable Options, The Introductory Text, The Customization Buffer
-@comment node-name, next, previous, up
-@subsection The Customization Options
-
-Each customization option looks similar to the following text:
-
-@example
- *** custom-background-mode: default
- State: this item is unchanged from its factory setting.
- [ ] [?] The brightness of the background.
-@end example
-
-The option contains the parts described below.
-
-@table @samp
-@item ***
-The Level Button. The customization options in the buffer are organized
-in a hierarchy, which is indicated by the number of stars in the level
-button. The top level options will be shown as @samp{*}. When they are
-expanded, the suboptions will be shown as @samp{**}. The example option
-is thus a subsuboption.
-
-Activating the level buttons will toggle between hiding and exposing the
-content of that option. The content can either be the value of the
-option, as in this example, or a list of suboptions.
-
-@item custom-background-mode
-This is the tag of the the option. The tag is a name of a variable, a
-face, or customization group. Activating the tag has an effect that
-depends on the exact type of the option. In this particular case,
-activating the tag will bring up a menu that will allow you to choose
-from the three possible values of the `custom-background-mode'
-variable.
-
-@item default
-After the tag, the options value is shown. Depending on its type, you
-may be able to edit the value directly. If an option should contain a
-file name, it is displayed in an editable field, i.e. you can edit it
-using the standard emacs editing commands.
-
-@item State: this item is unchanged from its factory setting.
-The state line. This line will explain the state of the option,
-e.g. whether it is currently hidden, or whether it has been modified or
-not. Activating the button will allow you to change the state, e.g. set
-or reset the changes you have made. This is explained in detail in the
-following sections.
-
-@item [ ]
-The magic button. This is an abbreviated version of the state line.
-
-@item [?]
-The documentation button. If the documentation is more than one line,
-this button will be present. Activating the button will toggle whether
-the complete documentation is shown, or only the first line.
-
-@item The brightness of the background.
-This is a documentation string explaining the purpose of this particular
-customization option.
-
-@end table
-
-@node The Variable Options, The Face Options, The Customization Options, The Customization Buffer
-@comment node-name, next, previous, up
-@subsection The Variable Options
-
-The most common customization options are emacs lisp variables. The
-actual editing of these variables depend on what type values the
-variable is expected to contain. For example, a lisp variable whose
-value should be a string will typically be represented with an editable
-text field in the buffer, where you can change the string directly. If
-the value is a list, each item in the list will be presented in the
-buffer buffer on a separate line, with buttons to insert new items in
-the list, or delete existing items from the list. You may want to see
-@ref{User Interface,,, widget, The Widget Library}, where some examples
-of editing are discussed.
-
-You can either choose to edit the value directly, or edit the lisp
-value for that variable. The lisp value is a lisp expression that
-will be evaluated when you start emacs. The result of the evaluation
-will be used as the initial value for that variable. Editing the
-lisp value is for experts only, but if the current value of the
-variable is of a wrong type (i.e. a symbol where a string is expected),
-the `edit lisp' mode will always be selected.
-
-You can see what mode is currently selected by looking at the state
-button. If it uses parenthesises (like @samp{( )}) it is in edit lisp
-mode, with square brackets (like @samp{[ ]}) it is normal edit mode.
-You can switch mode by activating the state button, and select either
-@samp{Edit} or @samp{Edit lisp} from the menu.
-
-You can change the state of the variable with the other menu items:
-
-@table @samp
-@item Set
-When you have made your modifications in the buffer, you need to
-activate this item to make the modifications take effect. The
-modifications will be forgotten next time you run emacs.
-
-@item Save
-Unless you activate this item instead! This will mark the modification
-as permanent, i.e. the changes will be remembered in the next emacs
-session.
-
-@item Reset
-If you have made some modifications and not yet applied them, you can
-undo the modification by activating this item.
-
-@item Reset to Saved
-Activating this item will reset the value of the variable to the last
-value you marked as permanent with `Save'.
-
-@item Reset to Factory Settings
-Activating this item will undo all modifications you have made, and
-reset the value to the initial value specified by the program itself.
-@end table
-
-By default, the value of large or complicated variables are hidden. You
-can show the value by clicking on the level button.
-
-@node The Face Options, The Group Options, The Variable Options, The Customization Buffer
-@comment node-name, next, previous, up
-@subsection The Face Options
-
-A face is an object that controls the appearance of some buffer text.
-The face has a number of possible attributes, such as boldness,
-foreground color, and more. For each attribute you can specify whether
-this attribute is controlled by the face, and if so, what the value is.
-For example, if the attribute bold is not controlled by a face, using
-that face on some buffer text will not affect its boldness. If the bold
-attribute is controlled by the face, it can be turned either on or of.
-
-It is possible to specify that a face should have different attributes
-on different device types. For example, a face may make text red on a
-color device, and bold on a monochrome device. You do this by
-activating `Edit All' in the state menu.
-
-The way this is presented in the customization buffer is to have a list
-of display specifications, and for each display specification a list of
-face attributes. For each face attribute, there is a checkbox
-specifying whether this attribute has effect and what the value is.
-Here is an example:
-
-@example
- *** custom-invalid-face: (sample)
- State: this item is unchanged from its factory setting.
- [ ] Face used when the customize item is invalid.
- [INS] [DEL] Display: [ ] Type: [ ] X [ ] PM [ ] Win32 [ ] DOS [ ] TTY
- [X] Class: [X] Color [ ] Grayscale [ ] Monochrome
- [ ] Background: [ ] Light [ ] Dark
- Attributes: [ ] Bold: off
- [ ] Italic: off
- [ ] Underline: off
- [X] Foreground: yellow (sample)
- [X] Background: red (sample)
- [ ] Stipple:
- [INS] [DEL] Display: all
- Attributes: [X] Bold: on
- [X] Italic: on
- [X] Underline: on
- [ ] Foreground: default (sample)
- [ ] Background: default (sample)
- [ ] Stipple:
- [INS]
-@end example
-
-This has two display specifications. The first will match all color
-displays, independently on what window system the device belongs to, and
-whether background color is dark or light. For devices matching this
-specification, @samp{custom-invalid-face} will force text to be
-displayed in yellow on red, but leave all other attributes alone.
-
-The second display will simply match everything. Since the list is
-prioritised, this means that it will match all non-color displays. For
-these, the face will not affect the foreground or background color, but
-force the font to be both bold, italic, and underline.
-
-You can add or delete display specifications by activating the
-@samp{[INS]} and @samp{[DEL]} buttons, and modify them by clicking on
-the check boxes. The first checkbox in each line in the display
-specification is special. It specify whether this particular property
-will even be relevant. By not checking the box in the first display, we
-match all device types, also device types other than those listed.
-
-After modifying the face, you can activate the state button to make the
-changes take effect. The menu items in the state button menu is similar
-to the state menu items for variables described in the previous section.
-
-@node The Group Options, The State Button, The Face Options, The Customization Buffer
-@comment node-name, next, previous, up
-@subsection The Group Options
-
-Since Emacs has approximately a zillion configuration options, they have
-been organized in groups. Each group can contain other groups, thus
-creating a customization hierarchy. The nesting of the customization
-within the visible part of this hierarchy is indicated by the number of
-stars in the level button.
-
-Since there is really no customization needed for the group itself, the
-menu items in the groups state button will affect all modified group
-members recursively. Thus, if you activate the @samp{Set} menu item,
-all variables and faces that have been modified and belong to that group
-will be applied. For those members that themselves are groups, it will
-work as if you had activated the @samp{Set} menu item on them as well.
-
-@node The State Button, The Customization Buttons, The Group Options, The Customization Buffer
-@comment node-name, next, previous, up
-@subsection The State Line and The Magic Button
-
-The state line has two purposes. The first is to hold the state menu,
-as described in the previous sections. The second is to indicate the
-state of each customization item.
-
-For the magic button, this is done by the character inside the brackets.
-The following states have been defined, the first that applies to the
-current item will be used:
-
-@table @samp
-@item -
-The option is currently hidden. For group options that means the
-members are not shown, for variables and faces that the value is not
-shown. You cannot perform any of the state change operations on a
-hidden customization option.
-
-@item *
-The value if this option has been modified in the buffer, but not yet
-applied.
-
-@item +
-The item has has been set by the user.
-
-@item :
-The current value of this option is different from the saved value.
-
-@item !
-The saved value of this option is different from the factory setting.
-
-@item @@
-The factory setting of this option is not known. This occurs when you
-try to customize variables or faces that have not been explicitly
-declared as customizable.
-
-@item SPC
-The factory setting is still in effect.
-
-@end table
-
-For non-hidden group options, the state shown is the most severe state
-of its members, where more severe means that it appears earlier in the
-list above (except hidden members, which are ignored).

-@subsection The Customization Buttons
-
-The last part of the customization buffer looks like this:
-
-@example
-[Set] [Save] [Reset] [Done]
-@end example
-
-Activating the @samp{[Set]}, @samp{[Save]}, or @samp{[Reset]}
-button will affect all modified customization items that are visible in

-@section Introduction
-
-Most graphical user interface toolkits, such as Motif and XView, provide
-a number of standard user interface controls (sometimes known as
-`widgets' or `gadgets'). Emacs doesn't really support anything like
-this, except for an incredible powerful text ``widget''. On the other
-hand, Emacs does provide the necessary primitives to implement many
-other widgets within a text buffer. The @code{widget} package
-simplifies this task.
-
-The basic widgets are:
-
-@table @code
-@item link
-Areas of text with an associated action. Intended for hypertext links
-embedded in text.
-@item push-button
-Like link, but intended for stand-alone buttons.
-@item editable-field
-An editable text field. It can be either variable or fixed length.
-@item menu-choice
-Allows the user to choose one of multiple options from a menu, each
-option is itself a widget. Only the selected option will be visible in
-the buffer.
-@item radio-button-choice
-Allows the user to choose one of multiple options by pushing radio
-buttons. The options are implemented as widgets. All options will be
-visible in the buffer.
-@item item
-A simple constant widget intended to be used in the @code{menu-choice} and
-@code{radio-button-choice} widgets.
-@item choice-item
-An button item only intended for use in choices. When pushed, the user
-will be asked to select another option from the choice widget.
-@item toggle
-A simple @samp{on}/@samp{off} switch.
-@item checkbox
-A checkbox (@samp{[ ]}/@samp{[X]}).
-@item editable-list
-Create an editable list. The user can insert or delete items in the
-list. Each list item is itself a widget.
-@end table
-
-Now of what possible use can support for widgets be in a text editor?
-I'm glad you asked. The answer is that widgets are useful for
-implementing forms. A @dfn{form} in emacs is a buffer where the user is
-supposed to fill out a number of fields, each of which has a specific
-meaning. The user is not supposed to change or delete any of the text
-between the fields. Examples of forms in Emacs are the @file{forms}
-package (of course), the customize buffers, the mail and news compose
-modes, and the @sc{html} form support in the @file{w3} browser.
-
-The advantages for a programmer of using the @code{widget} package to
-implement forms are:
-
-@enumerate
-@item
-More complex field than just editable text are supported.
-@item
-You can give the user immediate feedback if he enters invalid data in a
-text field, and sometimes prevent entering invalid data.
-@item
-You can have fixed sized fields, thus allowing multiple field to be
-lined up in columns.
-@item
-It is simple to query or set the value of a field.
-@item
-Editing happens in buffer, not in the mini-buffer.
-@item
-Packages using the library get a uniform look, making them easier for
-the user to learn.
-@item
-As support for embedded graphics improve, the widget library will
-extended to support it. This means that your code using the widget
-library will also use the new graphic features by automatic.
-@end enumerate
-
-In order to minimize the code that is loaded by users who does not
-create any widgets, the code has been split in two files:
-
-@table @file
-@item widget.el
-This will declare the user variables, define the function
-@code{widget-define}, and autoload the function @code{widget-create}.
-@item wid-edit.el
-Everything else is here, there is no reason to load it explicitly, as
-it will be autoloaded when needed.
-@end table
-
-@node User Interface, Programming Example, Introduction, Top
-@comment node-name, next, previous, up
-@section User Interface
-
-A form consist of read only text for documentation and some fields,
-where each the fields contain two parts, as tag and a value. The tags
-are used to identify the fields, so the documentation can refer to the
-foo field, meaning the field tagged with @samp{Foo}. Here is an example
-form:
-
-@example
-Here is some documentation.
-
-Name: @i{My Name} @strong{Choose}: This option
-Address: @i{Some Place
-In some City
-Some country.}
-
-See also @b{_other work_} for more information.
-
-Numbers: count to three below
-@b{[INS]} @b{[DEL]} @i{One}
-@b{[INS]} @b{[DEL]} @i{Eh, two?}
-@b{[INS]} @b{[DEL]} @i{Five!}
-@b{[INS]}
-
-Select multiple:
-
-@b{[X]} This
-@b{[ ]} That
-@b{[X]} Thus
-
-Select one:
-
-@b{(*)} One
-@b{( )} Another One.
-@b{( )} A Final One.
-
-@b{[Apply Form]} @b{[Reset Form]}
-@end example
-
-The top level widgets in is example are tagged @samp{Name},
-@samp{Choose}, @samp{Address}, @samp{_other work_}, @samp{Numbers},
-@samp{Select multiple}, @samp{Select one}, @samp{[Apply Form]}, and
-@samp{[Reset Form]}. There are basically two thing the user can do within
-a form, namely editing the editable text fields and activating the
-buttons.
-
-@subsection Editable Text Fields
-
-In the example, the value for the @samp{Name} is most likely displayed
-in an editable text field, and so are values for each of the members of
-the @samp{Numbers} list. All the normal Emacs editing operations are
-available for editing these fields. The only restriction is that each
-change you make must be contained within a single editable text field.
-For example, capitalizing all text from the middle of one field to the
-middle of another field is prohibited.
-
-Editing text fields are created by the @code{editable-field} widget.
-
-The editing text fields are highlighted with the
-@code{widget-field-face} face, making them easy to find.
-
-@deffn Face widget-field-face
-Face used for other editing fields.
-@end deffn
-
-@subsection Buttons
-
-Some portions of the buffer have an associated @dfn{action}, which can
-be @dfn{activated} by a standard key or mouse command. These portions
-are called @dfn{buttons}. The default commands for activating a button
-are:
-
-@table @kbd
-@item @key{RET}
-@deffn Command widget-button-press @var{pos} &optional @var{event}
-Activate the button at @var{pos}, defaulting to point.
-If point is not located on a button, activate the binding in
-@code{widget-global-map} (by default the global map).
-@end deffn
-
-@item mouse-2
-@deffn Command widget-button-click @var{event}
-Activate the button at the location of the mouse pointer. If the mouse
-pointer is located in an editable text field, activate the binding in
-@code{widget-global-map} (by default the global map).
-@end deffn
-@end table
-
-There are several different kind of buttons, all of which are present in
-the example:
-
-@table @emph
-@item The Option Field Tags.
-When you activate one of these buttons, you will be asked to choose
-between a number of different options. This is how you edit an option
-field. Option fields are created by the @code{menu-choice} widget. In
-the example, @samp{@b{Choose}} is an option field tag.
-@item The @samp{@b{[INS]}} and @samp{@b{[DEL]}} buttons.
-Activating these will insert or delete elements from a editable list.
-The list is created by the @code{editable-list} widget.
-@item Embedded Buttons.
-The @samp{@b{_other work_}} is an example of an embedded
-button. Embedded buttons are not associated with a fields, but can serve
-any purpose, such as implementing hypertext references. They are
-usually created by the @code{link} widget.
-@item The @samp{@b{[ ]}} and @samp{@b{[X]}} buttons.
-Activating one of these will convert it to the other. This is useful
-for implementing multiple-choice fields. You can create it wit
-@item The @samp{@b{( )}} and @samp{@b{(*)}} buttons.
-Only one radio button in a @code{radio-button-choice} widget can be selected at any
-time. When you push one of the unselected radio buttons, it will be
-selected and the previous selected radio button will become unselected.
-@item The @samp{@b{[Apply Form]}} @samp{@b{[Reset Form]}} buttons.
-These are explicit buttons made with the @code{push-button} widget. The main
-difference from the @code{link} widget is that the buttons are will be
-displayed as GUI buttons when possible.
-enough.
-@end table
-
-To make them easier to locate, buttons are emphasized in the buffer.
-
-@deffn Face widget-button-face
-Face used for buttons.
-@end deffn
-
-@defopt widget-mouse-face
-Face used for buttons when the mouse pointer is above it.
-@end defopt
-
-@subsection Navigation
-
-You can use all the normal Emacs commands to move around in a form
-buffer, plus you will have these additional commands:
-
-@table @kbd
-@item @key{TAB}
-@deffn Command widget-forward &optional count
-Move point @var{count} buttons or editing fields forward.
-@end deffn
-@item @key{M-TAB}
-@deffn Command widget-backward &optional count
-Move point @var{count} buttons or editing fields backward.

-@section Setting Up the Buffer
-
-Widgets are created with @code{widget-create}, which returns a
-@dfn{widget} object. This object can be queried and manipulated by
-other widget functions, until it is deleted with @code{widget-delete}.
-After the widgets have been created, @code{widget-setup} must be called
-to enable them.
-
-@defun widget-create type [ keyword argument ]@dots{}
-Create and return a widget of type @var{type}.
-The syntax for the @var{type} argument is described in @ref{Basic Types}.
-
-The keyword arguments can be used to overwrite the keyword arguments
-that are part of @var{type}.
-@end defun
-
-@defun widget-delete widget
-Delete @var{widget} and remove it from the buffer.
-@end defun
-
-@defun widget-setup
-Setup a buffer to support widgets.
-
-This should be called after creating all the widgets and before allowing
-the user to edit them.
-@refill
-@end defun
-
-If you want to insert text outside the widgets in the form, the
-recommended way to do that is with @code{widget-insert}.
-
-@defun widget-insert
-Insert the arguments, either strings or characters, at point.
-The inserted text will be read only.
-@end defun
-
-There is a standard widget keymap which you might find useful.
-
-@defvr Const widget-keymap
-A keymap with the global keymap as its parent.@*
-@key{TAB} and @kbd{C-@key{TAB}} are bound to @code{widget-forward} and
-@code{widget-backward}, respectively. @kbd{@key{RET}} and @kbd{mouse-2}
-are bound to @code{widget-button-press} and
-@code{widget-button-}.@refill
-@end defvr
-

-@section Basic Types
-
-The syntax of a type specification is given below:
-
-@example
-NAME ::= (NAME [KEYWORD ARGUMENT]... ARGS)
- | NAME
-@end example
-
-Where, @var{name} is a widget name, @var{keyword} is the name of a
-property, @var{argument} is the value of the property, and @var{args}
-are interpreted in a widget specific way.
-
-There following keyword arguments that apply to all widgets:
-
-@table @code
-@item :value
-The initial value for widgets of this type.
-
-@item :format
-This string will be inserted in the buffer when you create a widget.
-The following @samp{%} escapes are available:
-
-@table @samp
-@item %[
-@itemx %]
-The text inside will be marked as a button.
-
-@item %@{
-@itemx %@}
-The text inside will be displayed with the face specified by
-@code{:sample-face}.
-
-@item %v
-This will be replaces with the buffer representation of the widgets
-value. What this is depends on the widget type.
-
-@item %d
-Insert the string specified by @code{:doc} here.
-
-@item %h
-Like @samp{%d}, with the following modifications: If the documentation
-string is more than one line, it will add a button which will toggle
-between showing only the first line, and showing the full text.
-Furthermore, if there is no @code{:doc} property in the widget, it will
-instead examine the @code{:documentation-property} property. If it is a
-lambda expression, it will be called with the widget's value as an
-argument, and the result will be used as the documentation text.
-
-@item %t
-Insert the string specified by @code{:tag} here, or the @code{princ}
-representation of the value if there is no tag.
-
-@item %%
-Insert a literal @samp{%}.
-@end table
-
-@item :button-face
-Face used to highlight text inside %[ %] in the format.
-
-@item :doc
-The string inserted by the @samp{%d} escape in the format
-string.
-
-@item :tag
-The string inserted by the @samp{%t} escape in the format
-string.
-
-@item :tag-glyph
-Name of image to use instead of the string specified by `:tag' on
-Emacsen that supports it.
-
-@item :help-echo
-Message displayed whenever you move to the widget with either
-@code{widget-forward} or @code{widget-backward}.
-
-@item :indent
-An integer indicating the absolute number of spaces to indent children
-of this widget.
-
-@item :offset
-An integer indicating how many extra spaces to add to the widget's
-grandchildren compared to this widget.
-
-@item :extra-offset
-An integer indicating how many extra spaces to add to the widget's
-children compared to this widget.
-
-@item :notify
-A function called each time the widget or a nested widget is changed.
-The function is called with two or three arguments. The first argument
-is the widget itself, the second argument is the widget that was
-changed, and the third argument is the event leading to the change, if
-any.
-
-@item :menu-tag
-Tag used in the menu when the widget is used as an option in a
-@code{menu-choice} widget.
-
-@item :menu-tag-get
-Function used for finding the tag when the widget is used as an option
-in a @code{menu-choice} widget. By default, the tag used will be either the
-@code{:menu-tag} or @code{:tag} property if present, or the @code{princ}
-representation of the @code{:value} property if not.
-
-@item :match
-Should be a function called with two arguments, the widget and a value,
-and returning non-nil if the widget can represent the specified value.
-
-@item :validate
-A function which takes a widget as an argument, and return nil if the
-widgets current value is valid for the widget. Otherwise, it should
-return the widget containing the invalid data, and set that widgets
-@code{:error} property to a string explaining the error.

-When on a widget with no tabbing order specified, go to the next widget
-in the buffer with a positive tabbing order, or @code{nil}
-@end enumerate
-
-@item :parent
-The parent of a nested widget (e.g. a @code{menu-choice} item or an
-element of a @code{editable-list} widget).
-
-@item :sibling-args
-This keyword is only used for members of a @code{radio-button-choice} or

-
-The following extra properties are recognized.
-
-@table @code
-@item :size
-The width of the editable field.@*
-By default the field will reach to the end of the line.
-
-@item :value-face
-Face used for highlighting the editable field. Default is
-@code{widget-field-face}.
-
-@item :secret
-Character used to display the value. You can set this to e.g. @code{?*}
-if the field contains a password or other secret information. By
-default, the value is not secret.
-
-@item :valid-regexp
-By default the @code{:validate} function will match the content of the
-field with the value of this attribute. The default value is @code{""}
-which matches everything.
-
-@item :keymap
-Keymap used in the editable field. The default value is
-@code{widget-field-keymap}, which allows you to use all the normal
-editing commands, even if the buffers major mode supress some of them.
-Pressing return activates the function specified by @code{:activate}.
-
-@item :hide-front-space
-@itemx :hide-rear-space
-In order to keep track of the editable field, emacs places an invisible
-space character in front of the field, and for fixed sized fields also
-in the rear end of the field. For fields that extent to the end of the
-line, the terminating linefeed serves that purpose instead.
-
-Emacs will try to make the spaces intangible when it is safe to do so.
-Intangible means that the cursor motion commands will skip over the
-character as if it didn't exist. This is safe to do when the text
-preceding or following the widget cannot possible change during the
-lifetime of the @code{editable-field} widget. The preferred way to tell
-Emacs this, is to add text to the @code{:format} property around the
-value. For example @code{:format "Tag: %v "}.
-
-You can overwrite the internal safety check by setting the
-@code{:hide-front-space} or @code{:hide-rear-space} properties to
-non-nil. This is not recommended. For example, @emph{all} text that
-belongs to a widget (i.e. is created from its @code{:format} string) will
-change whenever the widget changes its value.

-
-A number of widgets for editing s-expressions (lisp types) are also
-available. These basically fall in three categories: @dfn{atoms},
-@dfn{composite types}, and @dfn{generic}.
-
-@menu
-* generic::
-* atoms::
-* composite::
-@end menu
-
-@node generic, atoms, Sexp Types, Sexp Types
-@comment node-name, next, previous, up
-@subsection The Generic Widget.
-
-The @code{const} and @code{sexp} widgets can contain any lisp
-expression. In the case of the @code{const} widget the user is
-prohibited from editing edit it, which is mainly useful as a component
-of one of the composite widgets.
-
-The syntax for the generic widgets is
-
-@example
-TYPE ::= (const [KEYWORD ARGUMENT]... [ VALUE ])
-@end example
-
-The @var{value}, if present, is used to initialize the @code{:value}
-property and can be any s-expression.
-
-@deffn Widget const
-This will display any valid s-expression in an immutable part of the
-buffer.
-@end deffn
-
-@deffn Widget sexp
-This will allow you to edit any valid s-expression in an editable buffer
-field.
-
-The @code{sexp} widget takes the same keyword arguments as the
-@code{editable-field} widget.
-@end deffn
-
-@node atoms, composite, generic, Sexp Types
-@comment node-name, next, previous, up
-@subsection Atomic Sexp Widgets.
-
-The atoms are s-expressions that does not consist of other
-s-expressions. A string is an atom, while a list is a composite type.
-You can edit the value of an atom with the following widgets.
-
-The syntax for all the atoms are
-
-@example
-TYPE ::= (NAME [KEYWORD ARGUMENT]... [ VALUE ])
-@end example
-
-The @var{value}, if present, is used to initialize the @code{:value}
-property and must be an expression of the same type as the widget.
-I.e. the string widget can only be initialized with a string.
-
-All the atom widgets take the same keyword arguments as the @code{editable-field}
-widget.
-
-@deffn Widget string
-Allows you to edit a string in an editable field.
-@end deffn
-
-@deffn Widget file
-Allows you to edit a file name in an editable field. You you activate
-the tag button, you can edit the file name in the mini-buffer with
-completion.
-
-Keywords:
-@table @code
-@item :must-match
-If this is set to non-nil, only existing file names will be allowed in
-the minibuffer.
-@end table
-@end deffn
-
-@deffn Widget directory
-Allows you to edit a directory name in an editable field.
-Similar to the @code{file} widget.
-@end deffn
-
-@deffn Widget symbol
-Allows you to edit a lisp symbol in an editable field.
-@end deffn
-
-@deffn Widget integer
-Allows you to edit an integer in an editable field.
-@end deffn
-
-@deffn Widget number
-Allows you to edit a number in an editable field.
-@end deffn
-
-@deffn Widget boolean
-Allows you to edit a boolean. In lisp this means a variable which is
-either nil meaning false, or non-nil meaning true.
-@end deffn
-
-
-@node composite, , atoms, Sexp Types
-@comment node-name, next, previous, up
-@subsection Composite Sexp Widgets.
-
-The syntax for the composite are
-
-@example
-TYPE ::= (NAME [KEYWORD ARGUMENT]... COMPONENT...)
-@end example
-
-Where each @var{component} must be a widget type. Each component widget
-will be displayed in the buffer, and be editable to the user.
-
-@deffn Widget cons
-The value of a @code{cons} widget is a cons-cell where the car is the
-value of the first component and the cdr is the value of the second
-component. There must be exactly two components.
-@end deffn
-
-@deffn Widget lisp
-The value of a @code{lisp} widget is a list containing the value of
-each of its component.
-@end deffn
-
-@deffn Widget vector
-The value of a @code{vector} widget is a vector containing the value of
-each of its component.
-@end deffn
-
-The above suffice for specifying fixed size lists and vectors. To get
-variable length lists and vectors, you can use a @code{choice},
-@code{set} or @code{repeat} widgets together with the @code{:inline}
-keywords. If any component of a composite widget has the @code{:inline}
-keyword set, its value must be a list which will then be spliced into
-the composite. For example, to specify a list whose first element must
-be a file name, and whose remaining arguments should either by the
-symbol @code{t} or two files, you can use the following widget
-specification:
-
-@example
-(list file
- (choice (const t)
- (list :inline t
- :value ("foo" "bar")
- string string)))
-@end example
-
-The value of a widget of this type will either have the form
-@samp{(file t)} or @code{(file string string)}.
-
-This concept of inline is probably hard to understand. It was certainly
-hard to implement so instead of confuse you more by trying to explain it
-here, I'll just suggest you meditate over it for a while.
-
-@deffn Widget choice
-Allows you to edit a sexp which may have one of fixed set of types. It
-is currently implemented with the @code{choice-menu} basic widget, and
-has a similar syntax.
-@end deffn
-
-@deffn Widget set
-Allows you to specify a type which must be a list whose elements all
-belong to given set. The elements of the list is not significant. This
-is implemented on top of the @code{checklist} basic widget, and has a
-similar syntax.
-@end deffn
-
-@deffn Widget repeat
-Allows you to specify a variable length list whose members are all of
-the same type. Implemented on top of the `editable-list' basic widget,
-and has a similar syntax.

-You can examine or set the value of a widget by using the widget object
-that was returned by @code{widget-create}.
-
-@defun widget-value widget
-Return the current value contained in @var{widget}.
-It is an error to call this function on an uninitialized widget.
-@end defun
-
-@defun widget-value-set widget value
-Set the value contained in @var{widget} to @var{value}.
-It is an error to call this function with an invalid @var{value}.
-@end defun
-
-@strong{Important:} You @emph{must} call @code{widget-setup} after
-modifying the value of a widget before the user is allowed to edit the
-widget again. It is enough to call @code{widget-setup} once if you
-modify multiple widgets. This is currently only necessary if the widget
-contains an editing field, but may be necessary for other widgets in the
-future.
-
-If your application needs to associate some information with the widget
-objects, for example a reference to the item being edited, it can be
-done with @code{widget-put} and @code{widget-get}. The property names
-must begin with a @samp{:}.
-
-@defun widget-put widget property value
-In @var{widget} set @var{property} to @var{value}.
-@var{property} should be a symbol, while @var{value} can be anything.
-@end defun
-
-@defun widget-get widget property
-In @var{widget} return the value for @var{property}.
-@var{property} should be a symbol, the value is what was last set by
-@code{widget-put} for @var{property}.
-@end defun
-
-@defun widget-member widget property
-Non-nil if @var{widget} has a value (even nil) for property @var{property}.
-@end defun
-
-Occasionally it can be useful to know which kind of widget you have,
-i.e. the name of the widget type you gave when the widget was created.
-
-@defun widget-type widget
-Return the name of @var{widget}, a symbol.
-@end defun
-
-Widgets can be in two states: active, which means they are modifiable by
-the user, or inactive, which means they cannot be modified by the user.
-You can query or set the state with the following code:
-
-@lisp
-;; Examine if @var{widget} is active or not.
-(if (widget-apply @var{widget} :active)
- (message "Widget is active.")
- (message "Widget is inactive.")
-
-;; Make @var{widget} inactive.
-(widget-apply @var{widget} :deactivate)
-
-;; Make @var{widget} active.
-(widget-apply @var{widget} :activate)
-@end lisp
-
-A widget is inactive if itself, or any of its ancestors (found by
-following the @code{:parent} link) have been deactivated. To make sure
-a widget is really active, you must therefore activate both itself, and
-all its ancestors.
-
-@lisp
-(while widget
- (widget-apply widget :activate)
- (setq widget (widget-get widget :parent)))
-@end lisp
-
-You can check if a widget has been made inactive by examining the value
-of @code{:inactive} keyword. If this is non-nil, the widget itself has
-been deactivated. This is different from using the @code{:active}
-keyword, in that the later tell you if the widget @strong{or} any of its
-ancestors have been deactivated. Do not attempt to set the
-@code{:inactive} keyword directly. Use the @code{:activate}
-@code{:deactivated} keywords instead.

-@section Defining New Widgets
-
-You can define specialized widgets with @code{define-widget}. It allows
-you to create a shorthand for more complex widgets, including specifying
-component widgets and default new default values for the keyword
-arguments.
-
-@defun widget-define name class doc &rest args
-Define a new widget type named @var{name} from @code{class}.
-
-@var{name} and class should both be symbols, @code{class} should be one
-of the existing widget types.
-
-The third argument @var{DOC} is a documentation string for the widget.
-
-After the new widget has been defined, the following two calls will
-create identical widgets:
-
-@itemize @bullet
-@item
-@lisp
-(widget-create @var{name})
-@end lisp
-
-@item
-@lisp
-(apply widget-create @var{class} @var{args})
-@end lisp
-@end itemize
-
-@end defun
-
-Using @code{widget-define} does just store the definition of the widget
-type in the @code{widget-type} property of @var{name}, which is what
-@code{widget-create} uses.
-
-If you just want to specify defaults for keywords with no complex
-conversions, you can use @code{identity} as your conversion function.
-
-The following additional keyword arguments are useful when defining new
-widgets:
-@table @code
-@item :convert-widget
-Function to convert a widget type before creating a widget of that
-type. It takes a widget type as an argument, and returns the converted
-widget type. When a widget is created, this function is called for the
-widget type and all the widgets parent types, most derived first.
-
-@item :value-to-internal
-Function to convert the value to the internal format. The function
-takes two arguments, a widget and an external value, and returns the
-internal value. The function is called on the present @code{:value}
-when the widget is created, and on any value set later with
-@code{widget-value-set}.
-
-@item :value-to-external
-Function to convert the value to the external format. The function
-takes two arguments, a widget and an internal value, and returns the
-internal value. The function is called on the present @code{:value}
-when the widget is created, and on any value set later with
-@code{widget-value-set}.
-
-@item :create
-Function to create a widget from scratch. The function takes one
-argument, a widget type, and create a widget of that type, insert it in
-the buffer, and return a widget object.
-
-@item :delete
-Function to delete a widget. The function takes one argument, a widget,
-and should remove all traces of the widget from the buffer.
-
-@item :value-create
-Function to expand the @samp{%v} escape in the format string. It will
-be called with the widget as its argument. Should
-insert a representation of the widgets value in the buffer.
-
-@item :value-delete
-Should remove the representation of the widgets value from the buffer.
-It will be called with the widget as its argument. It doesn't have to
-remove the text, but it should release markers and delete nested widgets
-if such has been used.
-
-@item :format-handler
-Function to handle unknown @samp{%} escapes in the format string. It
-will be called with the widget and the escape character as arguments.
-You can set this to allow your widget to handle non-standard escapes.
-
-You should end up calling @code{widget-default-format-handler} to handle
-unknown escape sequences, which will handle the @samp{%h} and any future
-escape sequences, as well as give an error for unknown escapes.
-@end table
-
-If you want to define a new widget from scratch, use the @code{default}
-widget as its base.
-
-@deffn Widget default [ keyword argument ]
-Widget used as a base for other widgets.
-
-It provides most of the functionality that is referred to as ``by
-default'' in this text.
