1 Introduction

TALCL: A libary that implements the TAL template language for common lisp

This library is a significant branch of the TAL implementation found in arnesi / ucw

Examples

See the examples directory for runable lisp code and tal templates.

Primary Goals

Flexibility, Debugability, and Consistency !

• To make working with templates (particularly XML/HTML) simple and support designer type folks working on them. Support the goal of non-lispers contributing to projects

• To be more flexible, easier to use, easier to debug, and with more helpful error messages than the original TAL from arnesi and ucw. TAL now has a single execution environment (the common lisp env) rather than its own private tal environment. It accomplishes this by runtime binding using progv. (IE: Most template variables are declared special. however due to package locks, anything that is in package :cl will not be declared, and thus produce warnings, but will still work correctly.)

• Easier to debug (again), it was very difficult to deduce what was wrong in most other template libraries, and I wanted to easily tell what part of the file was broken.

• Runtime information about what handlers and variables are available in the environment, can be accessed <tal:print-handlers> <tal:describe-handlers>, <tal:print-env>

• can easily include "bodies" that are passed as parameters to subtemplates See: examples/window.tal

• integrate well with cxml dom & our buildnode library. We want to be able to embed template content into our dom document in an efficient manner. Currently these are stored as processing instructions in the dom, and in serialization we play out the sax events we buffered when processing the template

• Tal tags can just be functions in common lisp that return cxml:dom snippets (see: buildnode)

• Lisp functions can just return direct stream writes / strings to the output document using <tal:content-as-is> - bypasses all validation careful!

• Plain text template support -> <tal:tal> stuff </tal:tal> renders as just the text (can be the whole template).

Changes From Arnesi / UCW tal

• Available without loading arnesi, yaclml, or ucw

• A single environment (tal environment is used only to pass values as parameters); TAL processing occurs in the standard common lisp runtime. TAL package determines what is currently available.

• Fixed inconsistencies about "$var" in non tal tags vs "var" in tal tags. $var should now work everywhere whether or not the tag or attribute is tal.

• More consistancy in evaluation rules

• More handlers, all handlers have tests

• tal:def handler for defining new sub templates

• output

• tal expression strings work in the body of a tag as well as attributes

• $$ escapes to a single $ sign

• $ evaluates one expression

• $var and ${var} returns the value of the var

• $(some-fn var) - calls some-fn with the value of var in the current package / env and splices the return into the doc

• ${nil} doesnt print anything

• DOM nodes and lists / vectors of dom-nodes can be spliced into the template EG: <span>$some-dom-content</span> will correctly put the dom content into the template

TAL Handlers

TAL handlers are tags / attributes that tal processes in a special way.

Handler Descriptions

These are the descriptions of each of the tal handlers that are available. This output was generated by the <tal:describe-handlers /> tag

NET.COMMON-LISP.PROJECT.BESE.TAL.CORE::DESCRIBE-HANDLERS

NET.COMMON-LISP.PROJECT.BESE.TAL.CORE:DEF
  [symbol]

DEF names a compiled function:
  Lambda-list: (TAG)
  Derived type: (FUNCTION (T) (VALUES NULL &OPTIONAL))
  Documentation:
    TAG-HANDLER: creates an inline sub-template available for the duration
    of the templates execution.
    
    The template should be named by the tal:name attribute or by
    tal:name-expression if it should be evaluated.
    
    
    Example:
       <tal:def tal:name='deffed-template'>
           <div>
             <span tal:when='$selected'>*</span>
             <span tal:content='$label'</span>
           </div>
       </tal>
    
    tal:def can also be used to create string constants when used with tal:type=\"string\"
    
    Example:
       <tal:def tal:name='deffed-string' tal:type='string'>This is my string</tal>
    
      results in a let binding (deffed-string \"This is my string\")

  [symbol]

INCLUDE names a compiled function:
  Lambda-list: (TAG)
  Derived type: (FUNCTION (T) *)

    TAG-HANDLER: includes another template at this point in the file.
    The template should be named by the tal:name attribute or by
    tal:name-expression if it should be evaluated.
    
    The path to the referenced template should be relative to the location
    of the template it is included in.
      
    The environment can be extended by including attributes in the
    parameter namespace, or immediate children in the parameter namespace.
    
    Example:
       <tal:include tal:name-expression='$tal-name' param:foo='foo' />
       <tal:include tal:name='other-template.tal' param:foo='foo'>
         <param:contents>
           <div>
             <span tal:when='$selected'>*</span>
             <span tal:content='$label'</span>
           </div>
         </param:contents>
       </tal>
    
    The template other-template.tal will be evaluated with the additional
    parameters of 'foo' and 'contents'.

Function: compile-tal-string STRING &optional EXPRESSION-PACKAGE &aux WARNINGS

Package

net.acceleration.talcl

Source

compile.lisp (file)

Function: content TAG

ATTRIBUTE-HANDLER:
Replaces the content of the tag with the evaluated value of the attribute. This tag escapes its content to be html-safe.

Example:
<div tal:content=’$foo’ class=’jack’/>
Gets output as
<div class=’jack’>
|Whatever was in $foo|
</div>

Package

net.common-lisp.project.bese.tal.core

Source

handlers.lisp (file)

Function: def TAG

TAG-HANDLER: creates an inline sub-template available for the duration
of the templates execution.

The template should be named by the tal:name attribute or by
tal:name-expression if it should be evaluated.

Example:
<tal:def tal:name=’deffed-template’>
<div>
<span tal:when=’$selected’>*</span>
<span tal:content=’$label’</span>
</div>
</tal>

tal:def can also be used to create string constants when used with tal:type="string"

Example:
<tal:def tal:name=’deffed-string’ tal:type=’string’>This is my string</tal>

results in a let binding (deffed-string "This is my string")

i.e. prevent escaping the bounds via ../../../

Package

net.acceleration.talcl

Source

tal-environment.lisp (file)

Function: in-package TAG

ATTRIBUTE-HANDLER: sets the package in which lisp evaluation happens.

Package

net.common-lisp.project.bese.tal.core

Source

handlers.lisp (file)

Function: include TAG

TAG-HANDLER: includes another template at this point in the file. The template should be named by the tal:name attribute or by tal:name-expression if it should be evaluated.

The path to the referenced template should be relative to the location of the template it is included in.

The environment can be extended by including attributes in the parameter namespace, or immediate children in the parameter namespace.

Example:
<tal:include tal:name-expression=’$tal-name’ param:foo=’foo’ /> <tal:include tal:name=’other-template.tal’ param:foo=’foo’> <param:contents>
<div>
<span tal:when=’$selected’>*</span>
<span tal:content=’$label’</span>
</div>
</param:contents>
</tal>

The template other-template.tal will be evaluated with the additional parameters of ’foo’ and ’contents’.

Package

net.common-lisp.project.bese.tal.core

Source

handlers.lisp (file)

Function: loop TAG

TAG-HANDLER: Loop across a list and repeat the children. On each
iteration the environment is extended with the value

tal:list should evaluate to a list
tal:constant-list is parsed as a comma separated string

<tal:loop tal:var=’class’ tal:list=’$efficiencies’>
<label class=’map-control-item’>
<img class=’marker-icon ${$class}’ />
<span class=’text’ tal:content=’$class’/>
<input type=’checkbox’ name=’filter-efficiency’ item-type=’${$class}’ /> </label>
</tal:loop>

assuming that $efficiencies resolves to the list {foo,bar}.
<label class=’map-control-item’>
<img class=’marker-icon foo’ />
<span class=’text’ tal:content=’foo’/>
<input type=’checkbox’ name=’filter-efficiency’ item-type=’foo’ /> </label>

Source

tal-environment.lisp (file)

Macro: rebinding BINDINGS &body BODY

Bind each var in BINDINGS to a gensym, bind the gensym to
var’s value via a let, return BODY’s value wrapped in this let.

Evaluates a series of forms in the lexical environment that is formed by adding the binding of each VAR to a fresh, uninterned symbol, and the binding of that fresh, uninterned symbol to VAR’s original value, i.e., its value in the current lexical environment.

The uninterned symbol is created as if by a call to GENSYM with the string denoted by PREFIX - or, if PREFIX is not supplied, the string denoted by VAR - as argument.

The forms are evaluated in order, and the values of all but the last are discarded (that is, the body is an implicit PROGN).

Syntax: WITH-UNIQUE-NAMES ( [ var | (var x) ]* ) declaration* form*

Executes a series of forms with each VAR bound to a fresh, uninterned symbol. The uninterned symbol is as if returned by a call to GENSYM with the string denoted by X - or, if X is not supplied, the string denoted by VAR - as argument.

The variable bindings created are lexical unless special declarations are specified. The scopes of the name bindings and declarations do not include the Xs.

The forms are evaluated in order, and the values of all but the last are discarded (that is, the body is an implicit PROGN).

Collects an attribute for the start tag that is currently being written.

This function may only be called during the extent of a use of @fun{with-element} or @fun{with-element*}, and only before the first child node has been written.

An attribute for the current element is recorded using the namespace prefix and local name specified by arguments. @var{prefix} is resolved to a namespace URI using the bindings established by @fun{with-namespace}, and that namespace URI is used for the attribute.
