README.md
MulleScion is a modern template engine for Objective C ============= (written in an oldfashioned way) *** It's **heavily** (very heavily) inspired by [TWIG]("http://twig.sensiolabs.org/") "The flexible, fast, and secure template engine for PHP" *MulleScion* is fairly flexible, reasonably fast and can be made as secure as you wish. * **Reasonably Fast** : *MulleScion* can compile templates into a compressed archive format. Loading such an archive is lots faster than parsing. A compiled template is read-only, you can use it many times to render different output from different input. * **Secure** : *MulleScion* has hooks so your application can ensure that untrusted template code doesn't have access to all of the applications data. * **Flexible** : There is the possibility of extending KVC and writing your own "builtin" fuctions. A template can (if allowed) execute arbitrary ObjC code. MulleScion has a powerful define like preprocessing capability and macros to expand your template vocabulary. Here is a simple example, where ObjC code is embedded in a template: <html> <!-- rendered by {{ [[NSProcessInfo processInfo] processName] }} on {{ [NSDate date]] }} --> <body> {% for item in [NSTimeZone knownTimeZoneNames] %} {% if item#.isFirst %} <table> <tr><th>TimeZone</th></tr> {% endif %} <tr><td>{{ item }}</td></tr> {% if item#.isLast %} </table> {% endif %} {% else %} Sorry, no timezone info available. {% endfor %} </body> </html> Using the MulleScion.framework the creation of a string from your object using a template file is as easy as: NSString *output; output = [MulleScionTemplate descriptionWithTemplateFile:@"test.scion" dataSource:self]; This is the general architecture of *MulleScion* ![](/dox/MulleScionDataFlow.png "Data Flow Sketch") ![](http://www.mulle-kybernetik.com/software/git/MulleScion/raw/master/dox/MulleScionDataFlow.png "Data Flow Sketch") *MulleScion* is currently still pretty much a "happy path" project, but it is already used in a commercial project. DOCUMENTATION ============= Virtually all the documentation is contained in example **.scion** templates in the `dox`folder. For each command or feature there should be a separate template file that documents it. mulle-scion, the command line utility, contains a small quickly hacked together webserver that can present the documentation using *MulleScion* itself. In Xcode just run `mulle-scion` and it should setup the webserver and open your browser to the right address. MulleScion is very similar to TWIG, so you can glean much of relevance from <http://twig.sensiolabs.org>. If you see a feature in TWIG but don't see it in the tests file, it's likely not there (but it's probably easily achieved some other way (define, macro, ObjC category on NSString). LIMITATIONS ============= Because you can execute arbitrary ObjC methods, and have access to Key Value Coding, MulleScion can pretty much do anything. *MulleScion* use `NSInvocation` for method calls, and that usually can not do variable arguments. So that will be a problem. Be wary of anything using structs and C-Arrays and C-strings, although *MulleScion* tries to be as helpful as possible. *MulleScion* do not do arithmetic or bitwise logic, quite on purpose. *MulleScion* `&&` and `||` have no operator precedence, use parentheses *MulleScion* don't prevent you from trying stupid things. The documentation is not very good, actually it is just more or less a collection of test cases with comments... iOS SUPPORT ============= There is a target that produces a "real framework" that you can add to your iOS projects. See https://github.com/kstenerud/iOS-Universal-Framework for more details about using "real frameworks" with Xcode. SITES ============= The main development site is Mulle kybernetiK. http://www.mulle-kybernetik.com/software/git/MulleScionTemplates/ releases are pushed to github github: https://github.com/mulle-nat/MulleScionTemplates/ TODO ============= It would be nice to have delayed evaluation for render results. Get rid of MulleScionNull except for printing a nil value. AUTHOR ============= Coded by Nat! 2013 Mulle kybernetiK Mongoose Webserver by Sergey Lyubka
