Note that it is not necessary to distinguish between keywords and symbols at this stage yet. Doing this reduces the time spent later on comparing strings in the parser.

thanks for the reply.

BTW: I need to say some words about your idea.

[...]

So, it have a fixed keywords definition which can be defined in the lexer grammar. So, the lexer can distinguish a c++ keyword and a general identifier.
When it meets a keyword, it just return a type id (int value), and no text is needed, this can avoid the hashtable search stage.

From my point of view, this way should be more faster.

Searching a wxString in a std::map<wxString,int> would be pretty fast, yes.
And the least strings needed for semantical analysis, the better, of course

I recently did a custom-language parser done in javascript (to make some javascript templates). I came to the same conclusion: Replacing string tokens with token ids is much, much faster. As a former CC dev, I applaud this initiative

Here is my code test:

Code Select Expand


void MyFunction(int paraA, float paramB)
{
   for(int index = 0; Foo* foofoo = Something.getFooByIndex(index); ++index)
   {
      // let's do something with foofoo
      foofoo->DoSomething();
      int i;
      i++;
   }
   
   //type + variable
   for(int a=0;a<10;a++)
   {
      int i;
      i++;
   };
   
   for(NS::MyClass a=0;a<100;a++)
   {
      int i;
      i++;
   };

   // type containing some template info
   for(MyNameSpace::MyTempLateClass<X,Y> a=0;a.DoSomething>b;a++)
       a++;

   // pointer declaration
   for(int *a=0;a<0x4444;a = a+4)
       ;
   for(int **a=0;a<0x4444;a = a+4)
       ;

   // two variables
   for(int *a=0, b=0;...)
;
}


and here is the result:

     variable index 3:13
     variable foofoo 3:29
     variable i 7:12

     variable a 31:15

But I think my parser is still not mature. , it need a long time and long way to go
