Class `dmd.lexer.Lexer`


						
				class Lexer
				
  : ErrorHandler
				;

Constructors

Name	Description
`this`	Creates a Lexer for the source code base[begoffset..endoffset+1]. The last character, base[endoffset], must be null (0) or EOF (0x1A).

Methods

Name	Description
`charConstant`
`combineComments`	Combine two document comments into one, separated by an extra newline if newParagraph is true.
`decodeUTF`	Decode UTF character. Issue error messages for invalid sequences. Return decoded character, advance p to last character in UTF sequence.
`delimitedStringConstant`	Lex a delimited string. Some examples of delimited strings are:
`escapeSequence`	Parse escape sequence.
`escapeSequence`	Parse the given string literal escape sequence into a single character.
`escapeStringConstant`	Scan a double-quoted string while building the processed string value by handling escape sequences. The result is returned in the given `t` token. This function assumes that `p` currently points to the opening double-quote of the string.
`getDocComment`	Parse doc comment embedded between t.ptr and p. Remove trailing blanks and tabs from lines. Replace all newlines with \n. Remove leading comment character from each line. Decide if it's a lineComment or a blockComment. Append to previous one for this token.
`hexStringConstant`	Lex hex strings: x"0A ae 34FE BD"
`inreal`	Read in characters, converting them to real.
`number`	Read in a number. If it's an integer, store it in tok.TKutok.Vlong. integers can be decimal, octal or hex Handle the suffixes U, UL, LU, L, etc. If it's double, store it in tok.TKutok.Vdouble.
`peekNext`	Look ahead at next token's value.
`peekNext2`	Look 2 tokens ahead at value.
`peekPastParen`	tk is on the opening (. Look ahead and return token that is past the closing ).
`poundLine`
`scan`	Turn next token in buffer into a token.
`stringPostfix`	Get postfix of string literal.
`tokenStringConstant`	Lex a token string. Some examples of token strings are:
`wysiwygStringConstant`	Lex a wysiwyg string. `p` must be pointing to the first character before the contents of the string literal. The character pointed to by `p` will be used as the terminating character (i.e. backtick or double-quote).
`error`	Report an error message.
`error`	Report an error message.
`factory`	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`opCmp`	Compare with another Object obj.
`opEquals`	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides for `opEquals` should attempt to compare objects by their contents.
`toHash`	Compute hash function for Object.
`toString`	Convert Object to a human readable string.
