Description:


STT (Smalltalk Templates) support. 
Enables embedding Smalltalk code in HTML and other documents too.

I'm a Smalltalk Template. 
My escaping sequence for embedding Smalltalk expressions is: {% %} or {%= %}.

    I changed these to <?stt ... ?>
    and                <?stt= ... ?>

Class protocol:

defaults
o  defaultAsStringSelector

instance creation
o  on: aString
Creates an instance of the receiver on aString

o  on: aString asStringSelector: aSymbol
Creates an instance of the receiver on aString

Instance protocol:

accessing
o  asStringSelector
Returns the selector used to show objects as Strings on the receiver

o  asStringSelector: aSymbol
Sets the selector used to show objects as Strings on the receiver

o  sttCode
Returns the receiver's Smalltalk Template code

caching
o  cache
Returns the receiver's cached object

o  cache: anObject
Save anObject in the receiver's cache

o  flushIfOlderThanFile: aFile

o  initializeCache
Initialize the receiver's cache

o  isCached
Tell if the receiver is cached or not. In the future,
this will consider the fact that a cached object may
become old after some time, and that means that the
object is NOT cached anymore.

o  isOlderThanFile: aFile

code generation
o  asSmalltalkCode: sttCode model: commancheModel
Returns the equivalent version of the receiver as Smalltalk code

o  asSmalltalkCodeWithModel: aModel
Returns the equivalent version of the receiver as Smalltalk code

o  writeOutputCodeFor: aString on: aStream
Writes on aStream the required Smalltalk code for sending aString as reply

compiling
o  compileFor: aComancheModel
Compiles the receiver's template in aClass and returns aCompiledMethod

evaluating
o  evaluateFor: aComancheModel
Evaluates the receiver within for anObject

initializing
o  initializeOn: aString asStringSelector: aSymbol

Examples:


Try these expressions: (STTTemplate on: 'Repeating word...<?stt 10 timesRepeat: [ ?> WORD <?stt ] ?> end!') evaluateFor: nil. (STTTemplate on: 'Counting: <?stt self to: 10 do: [ :each | ?> [<?stt = each ?>] <?stt ] ?>' ) evaluateFor: 1. obsolete (non xml-compliant): (STTTemplate on: 'Repeating word...{% 10 timesRepeat: [ %} WORD {% ] %} end!') evaluateFor: nil. (STTTemplate on: 'Counting: {% self to: 10 do: [ :each | %} [{%= each %}] {% ] %}' ) evaluateFor: 1. checking documents: XML::XMLParser processDocumentInFilename:'../../goodies/webServer/data/comancheSTT/test1.stt' beforeScanDo:[:p | p validate:false] XML::XMLParser processDocumentInFilename:'../../goodies/webServer/data/comancheSTT/test4.stt' beforeScanDo:[:p | p validate:false]
