Hello all,
I have modified the C++ grammar to support numbers with units.
float j = 3.0mV;
I created an action to replace the 3.0mV with 0.003 using the
following code in the grammar:
@init
{
string newNum(" ");
}
inside a rule alternative:
| un=UNITNUM //EAC here is where we replace the prefix with
multiplier
{
ConvertToNum($un, newNum);
printf("UnitNum= %s %s\n", $un.text->chars,
newNum.c_str());
$un.text = newNum;
} -> {newNum} // this is where I get lost
So how do I create the new pANTLR_BASE_TREE node and assign it the
string of interest?
I was thinking something like the following, but I don't know how to
assign the new token to the tree node.
pANTLR3_COMMON_TOKEN newTok = new ANTLR3_COMMON_TOKEN(un);
pANTLR3_STRING newString = new ANTLR3_STRING();
newString->set(newString, newNum.c_str());
newTok->setText(newTok, newString);
pANTLR3_BASE_TREE newNumTree = new ANTLR3_COMMON_TREE(<put
in the token?>);
Any help would be greatly appreciated!
