Runtime
- arrange named parameters into proper order (XML-RPC); convert ordered parameters into named ones (FORM POST) (bug 4997)
- add ERROR type (bug 4998)
- add BLOB type (bug 4999)
- consider Erlang notation: << 1, 2, 3 >>
- operations
- access: << 1, 2, 3 >> [ 2 ] -> 2
- concat: << 1, 3 >> .. << 3 >>
- splice: blob.splice(<< 1, 2, 3 >>, 0, 1, _) -> << 1, 3 >>
- throw an exception from inside an extension?!? (use case thinkfree extension)
- concurrent execution of independent page scripts
- caching of idempotent script function calls
- binary encoding of XML extensions for faster execution
- use another body for dekiscript errors: <body target="error" conflict="append">
- functions to add
- str.isNum(str)
- str.isBool(str)
- str.isUri(str)
Syntax
- Quick access
*doc
->
xml.text(doc)*url
->
web.xml(url) ?? web.text(url)
- discard statement (to evaluate an expression but not keep its output... do we really need this?)
- function definitions
- web expression language (the "on" attribute)
- on ::= clauses
- clauses ::= clause ( "or" clauses )?
- clause ::= condition "then" actions ( "else" actions )?
- condition ::= event ( "[" test "]" )?
- event ::= message-event | element-event | mouse-event | key-event
- message-event ::= message ( "[" test "]" )?
- test ::= ...
- element-event ::= "blur" | "change" | "focus"
- mouse-event ::= "click" | "contextmenu" | "dblclick" | "mousedown" | "mousemove" | "mouseout" | "mouseover" | "mousewheel"
- key-event ::= ( "keyup" | "keypress" | "keydown" ) ( "[" key-code "]" )?
- key-code ::= ...
- actions ::= action ( "after" time ) ( "if" ... )? ( "and" actions )?
- time ::= ...
- action ::= message-action | value-action | bind-action | set-action | css-action | layout-action | misc-action | script-action
- message-action ::= ...
- value-action ::= "value" "[" ... "]"
- bind-action ::= "bind" "[" ... "]"
- set-action ::= "set" "[" ... "]"

- script-action ::= "script" "[" ... "]"
Misc
- need shorthand syntax for template invocation {{ template.foo( .. .) }} is too long
- need a way to define variables without keeping the xml element around
- global variables
- samples
- example how to create a page with automatically substituted parmateres
- blog post on how to use JSON in dekiscript
- create sample how to process XML (e.g. rss reader)
- TRICK: use __env to pass in local variables
var username = user.name; var format = 'Hi $username' % __env; - wiki.directory("path:" .. page.path .. "/*")
- definition of standard javascript library for in-page mashups
- online directory of available extensions
- allow constants in extensions (e.g. num.e)
New Features with Missing Documentation
- 1.9
- dynamic page composition schema and mechanics
- 8.05.1
- <foreach>
work on xml documents too (e.g. <foreach in="xml['bar/foo']">) - multiple statements inside a single block
- functions with <access>internal</access> should not be listed in GET for script manifest
- foreach on maps, DON'T return key:value!!!
- $ is now set to 'args'
- $10 => $[10]
- $foo => $.foo
- uri.foo(1, 2, 3) -> uri("foo", [1, 2, 3])
- add support for SAVE:/EDIT: in attributes (e.g. <a href="http://wiki.developer.mindtouch.com/...eki/DekiScript">)
- allow substition on save or edit (i.e.{{ save: ... }} or {{ edit: ... }}))
- __request.args to access request query arguments
- <any init="var x = web.xml(foobar)" if="#x > 0" foreach="var k in x" where="k['bar']" block="var y = k['bar/foo']">inner</any>
-->
<eval:block value="var x = web.xml(foobar)">
<eval:if test="#x > 0">
<eval:foreach var="k" in="x" where="k['bar']">
<eval:block value="var y = k['bar/foo']">
<any class="script" function="syntax.xpp">inner</any>
</block>
</eval:foreach>
</eval:if>
</eval:block> - Scoping dekiscript to page of vars

<ul> foreach(var x in [1, 2, 3]) { <li> x </li>; } </ul>;
<strong> x .. 'foo'; ' '; </>;<div style="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: _fckstyle="float: right;" class=($class)> expr; </>;
- statement expressions
var x = (var y = 1; var z = y * 2; z + 3);
->
x == 5
- uri append operator
-
url & "path" & { option : value }
->
uri.build(url, path, { option : value })
-
- generators:
var x, y in collection where x > y, var z = x + y - map/list construction
[ x, y, z foreach var x, y in collection where x > y, var z = x + y]{ (x) : x + 1 foreach var x in num.series(1, 10) }
- the
is notoperator: x is not list - the
inandnot inoperators:x in [ 1, 2, 3 ]
y not in [ 1, 2, 3 ]
- <param> elements can now have a "default" attribute, which implies optional="true"; the contents of the default attribute are evaluated when the parameter is not explicitly provided.
- lists accept negative indices: values[-1]
- native xml syntax (with anonymous closing tags)
- DekiScript service
- detected @src attributes that start with
self:and replace them with the URI of the service location
- detected @src attributes that start with
- dekiscript
- Minneopa
- site.id (i.e. wiki-id); also present in implicit environment
- new config keys for native extensions
- uri.deki: uri for deki service
- apikey.deki: apikey for accessing privileged features in deki
