-- This package implements a token recognizer for an identifier. An
-- identifier is defined as a string starting with a character in a
-- given set of start characters and thereafter consisting of a
-- sequence of characters in the set of body characters. Single
-- underscores may be allowed inside identifiers. When the underscore
-- is in the set of characters, there is no restriction on its use.
--
-- If you use an identifier token with keyword tokens, they will
-- *both* typically match. So be sure to list the keyword tokens in
-- your syntax first, so that the keywords will take precedence.

-- This procedure will be called to create an Identifier token.
--
-- The defaults will give you an Ada-style identifier. For
-- identifiers that allow multiple underscores in a row, add the
-- underscore character to the Body_Chars. If it can also start
-- with an underscore, add the underscore character to the
-- Start_Chars.
--
-- Only set Has_Separator false when your identifier allows
-- multiple underscores in a row.
