code generation for #define ?

[OwenInCanada]

Hi all,

(EA 7.1 Build 833)

I am doing code generation with C and I am wondering how to get EA to generate the statement "#define MYCONSTANT 100".

The help for "Object Oriented Programming In C" states that the tagged value "define" applies to "Attributes" and Corresponds to "#define statement".

I tried adding an attribute MYCONSTANT to the class and adding a tagged value called "define" to that attribute, but it had no effect. Your suggestions would be very welcome.

Thanks,

Owen

Apparently you're close.

Set the value of the tag named define to "true".

Thanks that works! more or less

Now I have

Code: [Select]

typedef struct myRecord
{
  #define MYCONSTANT 100
  int myArray[MYCONSTANT ];
} myRecord;but I would prefer to have

Code: [Select]

#define MYCONSTANT 100
typedef struct myRecord
{
  int myArray[MYCONSTANT ];
} myRecord;
Can this be done by adjusting the metadata of the attribute MYCONSTANT ?   Or was it a mistake to make MYCONSTANT an attribute of the myRecord class?

Thanks and regards,

Owen

Yeah, you'll need to move it out of myRecord.  Which will probably mean defining an extra class that represents the file itself.

Thank you for the suggestions. Now I have moved my defines to a separate class, however they are still generated within a code block. Is it possible to get the defines to appear outside a code block?

Code: [Select]

/**
 * Collect several defines in one place.
 */
typedef struct ApiDataTypeDefines
{
      #define ECG_DMA_BUFSIZE 12
      #define ECG_FLASH_NUMBUFFERS 10

} ApiDataTypeDefines;
This example was generated using stereotype <<dataType>> applied to a block object in a SysML diagram.  I have tried many different stereotypes, and also setting each attribute as static, and the result is consistently as above.

Regards,

Owen
