Greetings all,
I hacked around on the stringTemplates in ANTLR earlier and got things to work,
but now I am trying to really understand them.
I am trying to clean up my Objective-C templates in order to facilitate
implementation of ST.stg in Objective-C.
I have got the template <ruleAttributeScopeImplementation(scope)> defined in
genericParser. My question is how do I convert the template
<ruleAttributeScopeImplementation(scope)> into the next two templates
(<ruleAttributeScopeImplementation(scope)> and
<ruleAttributeScopeImplementation.synthesize()> and get it to work. I guess
more succinctly the question is how do I get Antlr to recognize a new named
"sub" template and invoke it. Do I need to do something like this:
#pragma mark Rule attributes scope methods
<rules:{rule |
<rule.ruleDescriptor.ruleScope:ruleAttributeScopeImplementation.synthesize(scope=it)>}><\n>
in genericParser or do I need to do something more in
<ruleAttributeScopeImplementation(scope)>???
If so, what???
/******* START OF EXAMPLES ********/
ruleAttributeScopeImplementation(scope) ::= <<
/* start of ruleAttributeScopeImplementation */
<if(scope.attributes)>
@implementation <scope.name>_Scope<\n>
/******* MOVE THE FOLLOWING LINE TO A NEW TEMPLATE *******/
<scope.attributes:{a|@synthesize <a.name>;}; separator="\n"><\n>
+ (<scope.name>_Scope *)new<scope.name>_Scope
{
return [[[<scope.name>_Scope alloc] init] retain];
}
/********* a bunch more lines of template ************/
/********* end of these more lines ************/
@end /* end of <scope.name>_Scope implemtation */<\n>
<endif>
>>
/******_________CONVERT ABOVE TO BELOW_________*******/
ruleAttributeScopeImplementation.synthesize(scope) ::=<<
<scope.attributes:{a|@synthesize <a.name>;}; separator="\n"><\n>
>>
ruleAttributeScopeImplementation(scope) ::= <<
/* start of ruleAttributeScopeImplementation */
<if(scope.attributes)>
@implementation <scope.name>_Scope<\n>
/********** INVOKE THE NEW TEMPLATE HERE **********/
<ruleAttributeScopeImplementation.synthesize(scope)>
+ (<scope.name>_Scope *)new<scope.name>_Scope
{
return [[[<scope.name>_Scope alloc] init] retain];
}
/********* a bunch more lines of template ************/
/********* end of these more lines ************/
@end /* end of <scope.name>_Scope implemtation */<\n>
<endif>
>>
Thanks in Advance for any help given,
Alan
