Long Description

* caveman2-widgets
** What is it
caveman2-widgets is an extension library to [[https://github.com/fukamachi/caveman][caveman2]]. It is influenced
by [[https://github.com/skypher/weblocks][Weblocks]] and introduces its widget system for the developer. By
only using its widget concept it does not control the developer as
much as Weblocks itself. For people who don’t now Weblocks’ approach:
the developer can create web applications (more) like a normal GUI
application by using subclassable widgets which can have callbacks and
their like. Each Widget is only responsible for its own content but
might interfere with other objects through a given context.
#+LATEX: \\\\
But the really cool part is that the framework automatically creates
your site for dynamically (JavaScript based) access *and* normal
access. For the dynamic approach this means that you don’t have to
manage or even care to refresh parts of your website, because widgets
can do that by themselves!

** Usage
*** General
The only important thing is to run the function INIT-WIDGETS with an
<APP>. If you use caveman’s MAKE-PROJECT function you will get file
called "src/web.lisp". In this file you can adapt the following:
#+BEGIN_SRC lisp

(defpackage my-caveman2-webapp.web
(:use :cl
:caveman2
:caveman2-widgets ;; easy use of the external symbols of this project
:my-caveman2-webapp.config
:my-caveman2-webapp.view
:my-caveman2-webapp.db
:datafly
:sxql)
(:export :*web*))

;; some other code

;; the following will be generated through MAKE-PROJECT but is very important:
(defclass <web> (<app>) ())
(defvar *web* (make-instance ’<web>))
(clear-routing-rules *web*)

;; the neccessary call to initialize the widgets:
(init-widgets *web*)

;; from now on you can do whatever you want
#+END_SRC

*If you create objects from your widget classes, then please always
use the MAKE-WIDGET function!* This method should be used, since it
does all the background stuff for you.

*** Global scope
There are two scopes: /global/ and /session/. The global scope
"limits" the widget to *all* users. Therefore if you create a stateful
widget the state will be displayed to all users of your site. Use
MAKE-WIDGET with :GLOBAL to get a globally scoped widget.
#+LATEX: \\\\
A very simple example of what you can do with it:
#+BEGIN_SRC lisp
(defclass <global-widget> (<widget>)
((enabled
:initform nil
:accessor enabled)))

(defmethod render-widget ((this <global-widget>))
(if (enabled this)
"<h1>enabled!</h1>"
"<h1>not enabled</h1>"))

(defvar *global-widget* (make-widget :global ’<global-widget>))

(defroute "/" ()
(render-widget *global-widget*))

(defroute "/disable" ()
(setf (enabled *global-widget*) nil)
"disabled it")

(defroute "/enable" ()
(setf (enabled *global-widget*) t)
"enabled it")
#+END_SRC

A good practice to create disposable widgets is to mark
them :GLOBAL. In the following example the widget will be created when
a user connects and will afterwards immediately be destroyed again by
the garbage collector.
#+BEGIN_SRC lisp
(defroute "/" ()
(render-widget
(make-widget :global ’<string-widget>
:text "Hello world!"))
#+END_SRC

*** Session scope
The other option is to use a /session/ scope. This is a bit more
tricky because all your /session/ widgets must be stored within the
session (but not as user of this framework). :SESSION is the keyword
for MAKE-WIDGET to get a /session/ widget. Of course you only need to
save the top level (highest) widget of a widget tree in the session
(the children will be saved where the parent is). A short overview of
the functions:
- SET-WIDGET-FOR-SESSION :: Saves a widget in the session
variable. This should be considered ONLY for session scoped
widgets.
- GET-WIDGET-FOR-SESSION :: Gets a previously saved widget from the
session variable (e.g. to render it).
- REMOVE-WIDGET-FOR-SESSION :: Removes a saved widget from the session
variable.

An example (with children):
#+BEGIN_SRC lisp
(defclass <display-id-widget> (<widget>)
())

(defmethod render-widget ((this <display-id-widget>))
(concatenate ’string
"<h3>display-id-widget id: <a href=\"/rest/display-id-widget?id="
(caveman2-widgets.widget::id this)
"\">"
(caveman2-widgets.widget::id this)
"</a></h3>"))

(defclass <session-widget> (<widget>)
((id-widget
:initform (make-widget :session ’<display-id-widget>)
:reader id-widget)))

(defmethod render-widget ((this <session-widget>))
(concatenate ’string
"<h1>The id of your widget</h1>"
"<h2>It should be different for each session</h2>"
"<p>My id: <a href=\"/rest/session-widget?id="
(caveman2-widgets.widget::id this)
"\">"
(caveman2-widgets.widget::id this)
"</a></p>"
(render-widget (id-widget this))))

(defroute "/" ()
(set-widget-for-session :session-widget
(make-widget :session ’<session-widget>))
(concatenate ’string
"<head>
<script src=\"https://code.jquery.com/jquery-2.2.2.min.js\" type=\"text/javascript\"></script>
<script src=\"/widgets/js/widgets.js\" type=\"text/javascript\"></script>
</head>"

(render-widget
(get-widget-for-session :session-widget))
(render-widget
(make-widget :global ’<button-widget>
:label "Reset session"
:callback #’(lambda ()
(remove-widget-for-session :session-widget))))))

(defroute "/reset-session" ()
(remove-widget-for-session :session-widget)
"reset your session")
#+END_SRC

*** Some default widgets and layouts
There are some helpful default widgets which may help you with your
code organisation. These are:
- <COMPOSITE-WIDGET> :: A layout which contains widgets that will be rendered
vertically.
- <HCOMPOSITE-WIDGET> :: A layout like the <COMPOSITE-WIDGET> but renders the
widgets horizontally.
- <BORDER-WIDGET> :: A layout which features sections to put widgets
in. Please note that this widget has styles in
*/static/css/widgets.css*.
- <STRING-WIDGET> :: A widget which renders only a string.
- <FUNCTION-WIDGET> :: A widget which uses a supplied function for
rendering. Therefore the supplied function has to return a
string!

A simple example:
#+BEGIN_SRC lisp
(defroute "/composite" ()
(with-html-document
(doc
(make-instance ’<header-widget>))
(setf (body doc)
(make-widget
:global ’<border-widget>
:east (make-widget :global ’<string-widget>
:text "<h2>Hello from east</h2>")
:center
(make-widget
:global ’<hcomposite-widget>
:widgets (list
(make-widget :global ’<string-widget>
:text "<h1>Hello from left</h1>")
(make-widget :global ’<function-widget>
:function
#’(lambda ()
"<h1>Hello from the mid</h1>"))
(make-widget :global ’<string-widget>
:text "<h1>Hello from right</h1>")))
:west (make-widget :global ’<string-widget>
:text "<h2>Hello from west</h2>")))))
#+END_SRC
*** Buttons and links
You can use buttons and links that call specific functions. When you
create a button/link only for a session the created route will be
guarded. Therefore only the user with the associated route may
actually access his button.
#+LATEX: \\\\
For each button there will be an URI like "/buttons/BUTTONID". You can
access buttons via POST only. Links get a URI like "/links/LINKID" and
can be accessed either by GET (get a redirect to the stored link) or
by POST (return only the value of the link). In any case the callback
function gets called - please keep that in mind.
#+LATEX: \\\\
If the return value of the link matches the current path then the side
will be reloaded entirely or, if JavaScript is enabled, the dirty
widgets will be reloaded. Please leave out the starting "/" If you
want to address a target on the localhost. E.g. you are on the page
"/test", then return "test" if you want to stay on it.
#+LATEX: \\\\
The BUTTONID and LINKID are the ID slots of the widget - which is
default a symbol generated by GENSYM. But you can change that by
giving your <CALLBACK-WIDGET> a specific ID (like in the example
below). This will ensure that the route will persist otherwise the
route for the <CALLBACK-WIDGET> will change with every restart of your
website or with every new session (depends on the scope). *Be careful,
the ID must be unique on object level, otherwise you overwrite
routes!*
#+LATEX: \\\\
An example:
#+BEGIN_SRC lisp
(defvar *got-here-by-link* nil)

(defroute "/otherpage" ()
(if *got-here-by-link*
(progn
(setf *got-here-by-link* nil)
"<h1>Got here by pressing the link</h2>")
"<h1>Got here by yourself</h2>"))

(defroute "/link-test" ()
(concatenate ’string
(render-widget
(make-widget :global ’<link-widget>
:label "Github"
:callback #’(lambda (args)
(format t "LOG: Link clicked!") "http://github.com/ritschmaster")
:target-foreign-p t ;; The link goes out of this domain
))
(render-widget
(make-widget :global ’<link-widget>
:label "Otherpage"
:id "otherpage" ;; href="/links/otherpage"
:callback #’(lambda (args)
(setf *got-here-by-link* t) "/otherpage")
:target-foreign-p t ;; The link goes out of this domain
))
(render-widget
(make-widget :global ’<button-widget>
:label "Button"
:callback #’(lambda (args)
(format t
"LOG: Button clicked!"))))))
#+END_SRC

You can create your own callback widgets too. Just look at the
<CALLBACK-WIDGET>, <BUTTON-WIDGET> classes for that.

*** Use caveman2-widgets for your entire HTML document
To make your life really easy you can create an entire HTML
document. You can either tinker your own widgets or whatever with the
<HMTL-DOCUMENT-WIDGET> and the <HEADER-WIDGET> or you can use the
handy WITH-HTML-DOCUMENT macro.

#+BEGIN_SRC lisp
(defclass <root-widget> (<body-widget>)
())

(defmethod render-widget ((this <root-widget>))
"Hello world!")

(defclass <otherpage-widget> (<body-widget>)
())

(defmethod render-widget ((this <otherpage-widget>))
"Hello from the other page!")

(defvar *header-widget* (make-instance ’<header-widget>
;; the title when this header is used
:title "Widgets test"

;; the icon when this header is used
:icon-path "/images/icon.png"

;; the following lines will be rendered in the header: :other-header-content
’("<meta name=\"author\" content=\"Richard Bäck\">"))
(defvar *root-widget* (make-widget :global ’<root-widget>))
(defvar *otherpage-widget* (make-widget :global ’<otherpage-widget>))

(defroute "/" ()
;; The *root-widget* can be accessed under:
;; /rest/root-widget?id=(caveman2-widgets.widget::id *root-widget*)
(render-widget
(make-instance ’<html-document-widget>
;; sets this specific header for this page
:header *header-widget*
:body *root-widget*)))
(defroute "/otherpage" ()
(with-html-document (doc
*header-widget*)
(setf (body doc)
*otherpage-widget*)))

#+END_SRC

*** Marking widgets dirty
You can mark specific widgets as dirty with the function
MARK-DIRTY. This means that they will be reloaded dynamically (if the
user has JavaScript is enabled). Please notice that you can mark *any*
widget as dirty. Therefore you can order JavaScript to reload global
widgets and sessioned widgets.
#+LATEX: \\\\
An example:
#+BEGIN_SRC lisp
(defclass <sessioned-widget> (<widget>)
((enabled
:initform nil
:accessor enabled)))

(defmethod render-widget ((this <sessioned-widget>))
(concatenate ’string
"<h2>Sessioned-widget:</h2>"
(if (enabled this)
"<h3>enabled!</h3>"
"<h3>not enabled</h3>")))

(defclass <my-body-widget> (<widget>)
())

(defmethod render-widget ((this <my-body-widget>))
(concatenate ’string
"<h1>MARK-DIRTY test</h1>"
(render-widget
(get-widget-for-session :sessioned-widget))
(render-widget
(make-widget
:global ’<button-widget>
:label "Enable"
:callback #’(lambda ()
(let ((sessioned-widget
(get-widget-for-session :sessioned-widget)))
(when sessioned-widget
(setf (enabled sessioned-widget) t)
(mark-dirty sessioned-widget))))))
(render-widget
(make-widget
:global ’<button-widget>
:label "Disable"
:callback #’(lambda ()
(let ((sessioned-widget
(get-widget-for-session :sessioned-widget)))
(when sessioned-widget
(setf (enabled sessioned-widget) nil)
(mark-dirty sessioned-widget))))))))

(defvar *header-widget* (make-instance ’<header-widget>
:title "Mark-dirty test"))
(defvar *my-body-widget* (make-widget :global ’<my-body-widget>))

(defroute "/mark-dirty-test" ()
(set-widget-for-session :sessioned-widget (make-widget :session ’<sessioned-widget>))
(render-widget
(make-instance ’<html-document-widget>
:header *header-widget*
:body *my-body-widget*)))
#+END_SRC

*** Navigation objects
You can create navigation objects too! The purpose of navigation
objects is that you don’t have to manage a navigation ever again!
Each navigation object contains another widget which displays the
currently selected path. If you click on a navigation link that object
is changed and refreshed (either via JavaScript or through the
link). Please keep in mind that navigation objects are *session
stateful widgets*.
#+LATEX: \\\\
Paths are only created automatically by the DEFNAV macro. The first
item in the list is the widget which will be displayed at the base
path of the navigation. You can use any string as path but be careful
to not interfere with the special paths of NINGLE
(e.g. "/:some-path"). Do not use those. The only special path you can
use is the wildcard (e.g "/*/").
#+LATEX: \\\\
A very basic example:
#+BEGIN_SRC lisp
(defvar *first-widget*
(make-widget :global ’<string-widget>
:text "<h1>Hello world from first</h1>"))

(defvar *second-widget*
(make-widget :global ’<string-widget>
:text "<h1>Hello world from second</h1>"))

(defclass <proxy-widget> (<widget>)
()
(:documentation "This class enables session based widgets for a
navigation."))

(defmethod render-widget ((this <proxy-widget>))
(set-widget-for-session :string-widget
(make-widget :session ’<string-widget>
:text "hello world"))
(render-widget (get-widget-for-session :string-widget)))

(defnav "/sophisticated/path"
((make-instance ’<header-widget>
:title "Navigation test")
(list
(list "First widget" "first" *first-widget*)
(list "Second widget" "second" *second-widget*)
(list "Third widget" "third" (make-widget :global
’<proxy-widget>))
(list "Hidden widget" "hidden"
(make-widget :global ’<string-widget>
:text "<h1>You have accessed a hidden widget!</h1>")
:hidden))
:kind ’<menu-navigation-widget>))
#+END_SRC

If the default navigation object doesn’t render as you wish, you can
subclass it and overwrite the RENDER-WIDGET method. Please notice that
you can actually very easily adjust the path where the navigation and
its widgets get rendered. The slot BASE-PATH is created for that.
#+LATEX: \\\\
There are two default navigation widgets:
- <MENU-NAVIGATION-WIDGET> :: A navigation with a menu. You can change
the menu appearance with CSS. With the :HIDDEN keyword you can
hide a path from the navigation list.
- <BLANK-NAVIGATION-WIDGET> :: A navigation without any menu. It is
controlled by the URL only - or by other widgets.
*** Table objects
You can create a table very simple. A <TABLE-WIDGET> displays *all*
items which are supplied through the PRODUCER function.
#+LATEX: \\\\
Important for the usage of tables is that you supply a PRODUCER
function. The function should return a list of <TABLE-ITEM>
objects. This function can be anything but it has to take the key
arguments:
- AMOUNT :: Tells how many items to get
- ALREADY :: Tells how many items already received
- LENGTH-P :: A flag which should tell the function to return the
available items if active.
AMOUNT and ALREADY can be seen as synonyms for FROM and TO.
#+LATEX: \\\\
A <TABLE-ITEM> object is needed for tables. The essence of those
objects is that they can be translated to lists through the generic
function GET-AS-LIST. Therefore you don’t have to subclass
<TABLE-ITEM> at all just to add an implementation of GET-AS-LIST for
your used class.
#+LATEX: \\\\
For the <TABLE-Widget> consider the following example:
#+BEGIN_SRC lisp
(defclass <my-item> (<table-item>)
((id
:initarg :id
:reader id)
(name
:initarg :name
:reader name)
(description
:initarg :description
:reader description)))

(defmethod get-as-list ((this <my-item>))
(list :id (id this)
:name (name this)
:description (description this)))

(defun producer (&key
amount
(already 0)
(length-p nil))
(if (null length-p)
(let ((all ’()))
(if (null amount)
(loop for x from 1 to 1000 do
(setf all
(append all
(list
(make-instance ’<my-item>
:id x
:name (format nil "~a" x)
:description (format nil "The ~a. item." x))))))
(loop for x from (+ already 1) to (+ already amount) do
(setf all
(append all
(list
(make-instance ’<my-item>
:id x
:name (format nil "~a" x)
:description (format nil "The ~a. item." x)))))))
all)
1000))

(defvar *table-widget*
(make-widget :global ’<table-widget>
:producer ’producer
:column-descriptions (list
(list :name "Name")
(list :description "Description"))))

(defroute "/table" ()
(with-html-document (doc
(make-instance ’<header-widget>))
(setf (body doc)
*table-widget*)))
#+END_SRC

*** Viewgrids
The <VIEWGRID-WIDGET> is used to display a bulk of heterogenous
items. The items must implement the RENDER-AS method. The
<VIEWGRID-WIDGET> calls RENDER-AS with its VIEW slot. Therefore you
have provide an implementation for the keyword supplied by VIEW in
your <VIEWGRID-WIDGET>.
#+LATEX: \\\\
You can limit the displayed items with the MAX-ITEMS-TO-DISPLAY
slot. If this slot is active the items are delivered on several pages
instead on only one. If you supply additionally the DISPLAY-SELECTOR
with the URI path on which the <VIEWGRID-WIDGET> object is rendered,
then selectable page numbers are displayed on the bottom too.
#+LATEX: \\\\
Each item can be accessed. When accessing the item a specific
given function is called with the item as parameter.
#+LATEX: \\\\
The following example covers all functionality:
#+BEGIN_SRC lisp
(defclass <my-viewgrid-item> (<viewgrid-item>)
((id
:initarg :id
:reader id)
(name
:initarg :name
:reader name)
(description
:initarg :description
:reader description)))

(defmethod render-as ((this <my-viewgrid-item>) (view (eql :short)))
(format nil "<div style=\"padding-bottom:30px\">id: ~a<br>name: ~a<br>desc: ~a<div>"
(id this) (name this) (description this)))

(defun producer (&key
(from 0)
(to nil)
(length-p nil))
(let ((all ’()))
(loop for x from 1 to 35 do
(setf all
(append all
(list
(make-instance ’<my-viewgrid-item>
:id x
:name (format nil "~a" x)
:description (format nil "The ~a. item." x))))))
(cond
(length-p
(length all))
((and from (not to))
(mapcan #’(lambda (item)
(if (>= (id item) from)
(list item)
nil))
all))
((and from to)
(mapcan #’(lambda (item)
(if (and (>= (id item) from) (< (id item) to))
(list item)
nil))
all)))))

(defroute "/viewgrid" ()
(with-html-document (doc
(make-instance ’<header-widget>))
(set-widget-for-session
:viewgrid
(make-widget :session ’<viewgrid-widget>
:producer #’producer
:view :short
:max-items-to-display 11
:display-selector "viewgrid"
:on-view #’(lambda (item)
(format t
(render-as item :short))
"viewgrid")))
(setf (body doc)
(get-widget-for-session :viewgrid))))
#+END_SRC
*** Forms
Forms can be pretty annoying but with the <FORM-WIDGET> you don’t have
to care for anything but for the naming of the inputs ever again. Each
<FORM-WIDGET> consists of 0 to n <FORM-FIELD> objects. If you have 0
<FORM-FIELD> objects it essentially only behaves like a
<BUTTON-WIDGET>.
#+LATEX: \\\\
<FORM-FIELD> is the base class for fields. Fields can be:
- <INPUT-FIELD> :: Is basically an abstraction of the HTML input-tag.
- <SELECT-FIELD> :: Consists of <OPTION-FIELD> objects.

Of course you can implement your own <FORM-FIELD> classes too! But
keep in mind that *the default <FORM-FIELD> already implements
constraints*.
#+LATEX: \\\\
To understand how constraints for forms work an examination of the
available slots for <FORM-FIELD> objects is necessary:
- REQUIRED :: A non-nil value indicates that this field has to have
some value.
- SUPPLIED :: Will be set NIL by SET-REQUIRED-PRESENT and set T by
RENDER-WIDGET. It is NIL if the field is not supplied
and is therefore not dependent on REQUIRED. It should
tell the server whether an parameter was passed or not.
- CHECK-FUNCTION :: Will be called by SET-REQUIRED-PRESENT and check
if the passed value by the client is "correct". It
is a lambda with one argument, which is the passed
string from the client. Should return NIL if the
passed string was not correct and a non-nil value
otherwise.
- ERROR-HAPPENED :: Will be set to T by SET-REQUIRED-PRESENT if the
CHECK-FUNCTION did not succeed. The rendering the
form will set it to NIL again.
- ERROR-MESSAGE :: The message that will be displayed if
ERROR-HAPPENED is T.

You don’t have to actually care for that procedure as the
<FORM-WIDGET> calls this the SET-REQUIRED-PRESENT by itself. But it
can be helpful to understand the entire process of checking the user
input. The only thing to really memorize here is that *the given
callback only gets called if all required fields where supplied and
those fields where supplied correctly*.
#+LATEX: \\\\
Consider the following example for additional help:
#+BEGIN_SRC lisp
(defvar *password-field*
(make-instance ’<input-field>
:input-type "password"
:check-function
#’(lambda (pass)
(if (<= (length pass)
2)
nil
t))
:error-message "Has to be longer than 2"
:name "password"
:value ""))

(defvar *form-widget*
(let ((text-field (make-instance ’<input-field>
:input-type "text"
:name "text"
:value ""
:required t))
(choice-field (make-instance
’<select-field>
:name "selection"
:options
(list (make-instance ’<option-field>
:value "first")
(make-instance ’<option-field>
:value "second"
:display-value "Other")))))
(make-widget :global ’<form-widget>
:input-fields (list
text-field
*password-field*
choice-field)
:label "Submit"
:callback
#’(lambda (args)
(format t "received correct values:
~a
————-"
args)))))

(defroute "/form" ()
(with-html-document (doc
(make-instance ’<header-widget>))
(setf (body doc)
*form-widget*)))
#+END_SRC
*** Protecting widgets
This library also enables you to protect widgets. Each widget has an
associated list of keywords which indicate the levels/circles of
authorization an requester needs.
#+LATEX: \\\\
By default the protection is an empty list (therefore NIL), which
means that everybody can access your widget. If the protection is
non-nil the non-nil value is a list of keywords which refers to a list
of keywords stored in the session. So if the session contains the
required keyword in its list the requester can access the
widget. Otherwise he is denied (throws a 403 code).
#+LATEX: \\\\
The <WIDGET> class holds the PROTECTED slot. This slots value
indicates the needed token in the session. But caveman2-widgets
supplies an additional, specific *PROTECT-WIDGET* method which should be
used. You can supply the following parameters:
- :LOGIN :: Protects the widget by the default login-widget
- A keyword in general :: Protects the widget with this keyword (adds
it)
- A list of keywords :: Protects the widget with this keywords (adds
them)

#+BEGIN_SRC lisp
(defvar *specific-protected-widget*
(protect-widget
(make-widget :global ’<string-widget>
:text "<h1>This is a protected text</h1>")
:myprotection))

;; Should throw 403
(defroute "/protected-widget" ()
(concatenate ’string
"<a href=\"/rest/string-widget?id="
(id *specific-protected-widget*)
"\">Will throw 403</a>"

*** Login
Protecting certain widgets by a login is very easy. The <LOGIN-WIDGET>
organizes the following things:
1. It displays a login form and logs the client in if he passes the
challenge. The successful pass sets will result in an permanent
non-nil value if you call "(LOGGED-IN *SESSION*)". This means that
every widget that requires the authroization level :LOGIN through
the PROTECT-WIDGET method can now be accessed by the user.
2. It supplies a Logout button. This button can be access through the
LOGOUT-BUTTON reader. You therefore can render the button anywhere
you like. Pressing the button will result in a logout and therefore
in a permanent NIL for "(LOGGED-IN *SESSION*)".
3. It renders certain widgets if the login was successful. This can be
either used e.g. for a success message.

*The <LOGIN-WIDGET> has to run in :SESSION scope!*
#+LATEX: \\\\
Additionally you can specify different authentication challanges
(authentication functions) if you wish. But using the <LOGIN-WIDGET>
and passing the challenge will *only* set the authoriatzition level
to :LOGIN. This means that you need to create your own <LOGIN-WIDGET>
if you want some other level for different authentication functions!

#+BEGIN_SRC lisp
(defvar *protected-widget*
(protect-widget
(make-widget :global ’<string-widget>
:text "<h1>This is a protected text</h1>")
:login))

(defroute "/" ()
(with-html-document (doc
(make-instance ’<header-widget>))
(setf (body doc)
(make-widget
:global ’<function-widget>
:function
#’(lambda ()
(set-widget-for-session ;; running it in the session
:login-widget
(make-widget :session ’<login-widget>
:authenticator
#’(lambda (user password)
(if (and (string= user "ritschmaster")
(string= password "secret"))
t
nil))
:widgets
(list
*protected-widget*)))
(render-widget
(get-widget-for-session :login-widget)))))))
#+END_SRC
*** Language getting/setting
To store the accpeted languages in the session there is the
CHECK-AND-SET-LANGUAGE function. This function uses the value supplied
through the "Accept-languages" field in the HTTP request. It gets
called through the render method by any <HTML-DOCUMENT-WIDGET>
automatically. Which means that as soon as you use it you don’t have
to worry about getting the language. But on the other hand you have to
make sure that every subclass of <HTML-DOCUMENT-WIDGET> again uses
CHECK-AND-SET-LANGUAGE in its render-method.
#+LATEX: \\\\
You can access the currently accepted languages through the
ACCEPTED-LANGUAGES.
#+LATEX: \\\\
If you rather use a manual language chooser you can supply
AUTOMATICALLY-SET-LANGUAGES as NIL to the INIT-WIDGETS
function. Please then use the setf method for ACCEPTED-LANGUAGES to
set the language.
*** Translations
Most strings that are rendered human readable get translated through a
special function. You can specify your own translation function by
passing it to INIT-WIDGETS as :TRANSLATION-FUNCTION. The function
header should look like this:
#+BEGIN_SRC lisp
(defvar *my-translation-function*
#’(lambda (text
&key
plural-p
genitive-form-p
items-count
accusative-form-p
language
&allow-other-keys)
text))
#+END_SRC

Strings that are translated:
- The page names of a navigation

Strings that are definitely *not* translated:
- The TEXT of a <STRING-WIDGET>
- The return value of a <FUNCTION-WIDGET>

*** Development hooks
In case you want to do things at compile time (e.g. calling DEFROUTE)
whe INIT-WIDGETS is evaluated there is the variable
*INIT-WIDGETS-HOOKS*. Just append new functions as you wish.

#+BEGIN_SRC lisp
(setf *init-widgets-hooks*
(append
*init-widgets-hooks*
(list
#’(lambda ()
(defroute "/something" ()
;; Accessing the user supplied <APP> object:
(describe caveman2-widgets::*web*)
"something")))))
#+END_SRC
** Important notes/Things that happen automatically
The following things you should keep in mind when using
caveman2-widgets.

*** Automatically REST API creation
If you create a widget then routes for a REST API will be added
automatically. Suppose you subclass <WIDGET> with the class
<MY-WIDGET>, then you will get the path "/rest/my-widget" which you
can access.

#+BEGIN_SRC lisp
(defclass <my-widget> (<widget>)
())

(defmethod render-widget ((this <my-widget>))
"my-widget representation for the website")

(defmethod render-widget-rest ((this <my-widget>) (method (eql :get)) (args t))
"my-widget representation for the REST.")

(defmethod render-widget-rest ((this <my-widget>) (method (eql :post)) (args t))
(render-widget this))
#+END_SRC

Buttons and Links are *not* accessed through the REST path (see the
section above).

Widgets that are not accessible through the REST:
- <HTML-DOCUMENT-WIDGET>
- <HEADER-WIDGET>

*** Encapsulating widgets with divs
Each widget gets wrapped in a div automatically. Every widget will get
its entire class heritage included in the CSS class
attribute. Therefore you can access every widget (and derived widget)
very easily with CSS.

*** JavaScript dependencies
When <HEADER-WIDGET> is used all JavaScript dependencies are added
automatically. Please notice that these dependecies are needed to
ensure that the widgets work properly. If you don’t want to use
<HEADER-WIDGET> you have to manually add jQuery and all the JavaScript
Code supplied/needed by caveman2-widgets.

The routes for the JavaScript files (which have to be included in each
HTML file) are:
- /widgets/js/widgets.js

The jQuery-Version used is 2.2.2 minified. If you want another jQuery
file you can specify it with the variable \*jquery-cdn-link\* (should be
an URL).

*If you forget to use the JavaScript-files widgets might not work or
even break. Most likely all dynamic content just won’t work
(automatically fallback to non-JS)*

*** CSS dependencies
As with JavaScript, stylesheets are added in the <HEADER-WIDGET> automatically
too. The routes you need in your head tag are:
- /widgets/css/widgets.css

*** Session values
This section should inform you about keywords in the session variable
which you should absolutely not modify.
- :WIDGET-HOLDER :: <WIDGET-HOLDER> object. It holds all the session
scoped widgets.
- :DIRTY-OBJECT-IDS :: The name says it all.
- :JAVASCRIPT-AVAILABLE :: Holds a boolean value if JavaScript is
available or not.
- :ACCEPT-LANGUAGE :: Holds the languages accepted by the client.
