fast-dds-gen-3.3.0 with idl-parser 3.0.0 : idl parse error observed when integer constant is set with a enumeration value

[srchaitu2008]

Hi @richiware ,

Given below is another IDL file for which the processing fails (tested with idl-parser 3.0.0 alongwith fast-dds-gen 3.3.0 with the fix for fast-dds-gen issue 373 included ) :

module module1
{
enum mod1_enum_val
{
value1,
value2
}; //mod1_enum_val
}; //module1
const int32 myValUsingFullPathAsInt32 = module1::mod1_enum_val::value1;
const module1::mod1_enum_val myValUsingFullPath = module1::mod1_enum_val::value1;
const module1::mod1_enum_val myVal = module1::mod1_enum_val::value2;
module Top
{
const uint32 MAXLEN = 64;
const uint32 SeqLenAssumingThisModule = MAXLEN;
const uint32 SeqLen = Top::MAXLEN;
}; //Top
struct Sub
{
int32 userID;
double f64Data;
uint8 vChar;
}; //Sub
enum Modes
{
MODE1, //11
MODE2, //20
MODE3 //200
}; //Modes
const int32 myDefaultModeAsInt32 = Modes::MODE3;
const Modes myDefaultMode = Modes::MODE3;
const Modes myDefaultMode1 = Modes::MODE2;
typedef Sub SubSequence[Top::SeqLen];
struct AllSubs
{
SubSequence Subs;
}; //AllSubs

Error

Processing the file /tmp/IdlError3.idl...

/tmp/IdlError3.idl:30:47: error: Error evaluating expression: ;Top_MAXLEN=64;Top_SeqLenAssumingThisModule=64;Top_SeqLen=64;(Modes_MODE3) | 0

Raising this issue as indicated in comments of fast-dds-gen issue 373

Thanking you,
