Hi, guys!

I would like to ask about D Lexical.

As I understand the D Source Text consists of the following:

*Source Text **white spaces **end of lines **comments **tokens **special token sequences **end of file

Then, D Tokens consist of the following:

*tokens **Identifiers **String Literals **Character Literals **Integer Literals **Float Literals **Keywords **Some Characters

My question is this:
How do you name those characters (delimiters, operators or somehow else)? I know
that in Ada programming language the following characters are called
“delimiters”:

/
/=

I called them 'symbols'
I think a more appropriatre name might be 'operators'

I think it doesn't really matter, though!

I don't know Ada, but do you mean things like braces and semicolons ({, }, ;)?  I wrote a C-style scripting language parser thing, and I called those "particles."  This is to parallel the use of particles in Japanese, which do not have any inherent meaning, but which simply define the grammatical structure of the sentence.  In the same way, braces and semicolons simply describe the structure of the program, and really only have meaning to the compiler and aren't directly represented in the final machine code which is generated.

go to  http://www.digitalmars.com/d/lex.html  and look at 'Tokens'.

As i understand, D Tokens are Identifiers, Sring Literals, Charachter Literals, Integer Literals, Float Literals, Keywords, and above-mentioned symbols. How do you call those symbols - Symbols, Operators, or Delimiters?

Look at http://en.wikibooks.org/wiki/Ada_Programming/Lexical_elements http://en.wikibooks.org/wiki/Ada_Programming/Operators http://en.wikibooks.org/wiki/Programming:C_plus_plus/Operators_Table http://en.wikibooks.org/wiki/C_Sharp_Programming/Operators

I think that there should be a standard name for it. What do you think?

It's worth noting that operators are only delimiters because the language spec says they are.  Some languages actually require whitespace between identifiers, literals, and operators.
