cl-formsA web forms handling library
Mariano Montone <marianomontone@gmail.com>

# CL-FORMS #
CL-FORMS is a web forms handling library for Common Lisp.
Although it is potentially framework agnostic, it runs on top of Hunchentoot at the moment.
It features:
* Several form field types: String, boolean, integer, email, password fields. And more.
* Custom fields. CL-FORMS is extensible and it is possible to define new field types.
* Server and client side validation
* Rendering backends. Forms can be rendered via CL-WHO, or Djula, or something else; the backend is pluggable. The default renderer is CL-WHO.
* Themes (like Bootstrap)
* Control on rendering and layout.
* Handling of form errors.
* CSRF protection
## Basics ##
Use ‘defform‘ to define a form. Example:
“‘lisp
(defform fields-form (:action "/fields-post")
((name :string :value "")
(ready :boolean :value t)
(sex :choice :choices (list "Male" "Female") :value "Male")
(submit :submit :label "Create")))
“‘
On your web handler, grab the form via ‘find-form‘, select a renderer with ‘with-form-renderer‘and then render the form with ‘render-form‘:
“‘lisp
(let ((form (forms::find-form ’fields-form)))
(forms:with-form-renderer :who
(forms:render-form form))
“‘
To handle the form, grab it via ‘find-form‘ and then call ‘handle-request‘ (you should probably also call ‘validate-form‘ after).
Then bind form fields via either ‘with-form-field-values‘, that binds the form field values; or ‘with-form-fields‘ that binds the form fields.
“‘lisp
(let ((form (forms:find-form ’fields-form)))
(forms::handle-request form)
(forms::with-form-field-values (name ready sex) form
(who:with-html-output (forms.who::*html*)
(:ul
(:li (who:fmt "Name: ~A" name))
(:li (who:fmt "Ready: ~A" ready))
(:li (who:fmt "Sex: ~A" sex))))))
“‘
Plase have a look at the demo sources for more examples of how to use the library
## DEMO ##
There’s a demo included. To run:
“‘lisp
(require :cl-forms.demo)

Definitions are sorted by export status, category, package, and then by lexicographic order.
Whether to encode form parameters in base64 or not.
Define a form at top-level.
ARGS are the arguments passed to FORM class via MAKE-INSTANCE.
FIELDS are the form field specs.
@lisp

Registers a function with arguments ARGS and body BODY as a form builder.
BODY is expected to instantiate a FORM object using ARGS in some way.
FORM-NAME is the symbol under which the FORM is registered.
Use FIND-FORM with FORM-NAME and expected arguments to obtain the registered form.
Bind *FORM* to FORM and evaluate BODY in that context.
Bind the value of FIELDS in FORM.
Example:
@lisp
(with-form-field-values (name) form
(print name))
@end lisp
Bind FIELDS to the form fields in FORM.
Example:
@lisp
(with-form-fields (name) form
(print (field-value name)))
@end lisp
Also see: WITH-FORM-FIELD-VALUES
Bind *FORM-RENDERER* to RENDERER and evaluate BODY in that context.
Define a FORM named FORM-NAME and render it at the same time.
Bind *FORM-THEME* to FORM-THEME and evaluate BODY in that context.
Add an error on FIELD
Fill a FORM from a MODEL.
Read MODEL using FORM accessors and set the FORM field values.
Set a MODEL’s values from FORM field values.
Get the form named NAME.
ARGS is the list of arguments to pass to a possible form builder function.
See: DEFFORM-BUILDER macro.
Populates FORM from parameters in HTTP request. After this, the form field contains values, but they are not validated. To validate call VALIDATE-FORM after.
Create a field formatter. SYMBOL is the function to call.
Render form FIELD, both label and widget.
Render the validation errors associated with FIELD.
Render the label of FIELD.
Render FIELD widget.
