Instance protocol:

accessing
o  id
Return a unique integer id of this language.
For languages built into the VM, it must be < 32.
This id is used as index to various structures used by runtime
(bytecode set ?).
cg: this ought to be better documented - I have no idea, where it is used

o  name
Answers a human-readable name of myself:
'Smalltalk' for SmalltalkLanguage,
'Ruby' for RubyLanguage
...

o  sourceFileSuffix
Answers a default suffix for source files, i.e.
'st' for Smalltalk, 'js' for JavaScript or 'rb' for Ruby', etc.

accessing-classes
o  codeGeneratorClass
Answers a class that can generate code

o  compilerClass
Answer a class suitable for compiling a source code in 'my' language

o  compilerClassForInteractiveTools
( an extension from the stx:libtool package )
Answer a compiler class suitable for usage in interactive tools.
Such class may better integrate into the IDE and register for undo/redo
and/or do more checks and so on. Defaults to #compilerClass

o  compilerWithBreakpointSupportClass
Answer a class suitable for compiling a source code with breakpoints
in 'my' language

o  explainerClass
Answers a class used by browser and debugger to
show some hints about the code. It is OK to return
nil, which means that there is no explainer for given language.

o  formatterClass
Answer a class suitable for prettyPrinting (indenting) code in 'my' language.
It is ok to return nil, which means that the browser will not be able to prettyprint.

o  parserClass
Answer a class suitable for parsing a source code in 'my' language

o  sourceFileReaderClass
Answers a class that can be used for reading & compiling source files

o  sourceFileWriterClass
Answers a class is used for source file writing (i.e. file-out)

o  syntaxHighlighterClass
return the class to use for syntaxHighlighting (prettyPrinting) this class -
this can be redefined in special classes, to highlight classes with
Lisp, Prolog, ASN1, Basic :-) or whatever syntax.

mimicry
o  , anObject
Emulates symbol behavior. This is sometimes required
as 'Smalltalk language' is used by legacy code to access
the current language setting.
Future versions should contain class Locale.
cg: this is crab, who needs this?


** This is an obsolete interface - do not use it (it may vanish in future versions) **

queries
o  canBeCompiled
true if compilable in the browser

source queries
o  bracketStrings
used for autoindent

o  commentStrings
EOL comment

o  methodDefinitionTemplateForSelector: aSelector andArgumentNames: argNames
given a selector, return a prototype definition string

Usage example(s):

     SmalltalkLanguage instance 
        methodDefinitionTemplateForSelector:#foo andArgumentNames:#()
     SmalltalkLanguage instance
        methodDefinitionTemplateForSelector:#+ andArgumentNames:#('aNumber')
     SmalltalkLanguage instance
        methodDefinitionTemplateForSelector:#foo:bar:baz: andArgumentNames:#('fooArg' 'barArg' 'bazArg')

testing
o  isSmalltalk
true iff I represent the smalltalk language
