Class FortranTokenMarker

      org.gjt.sp.jedit.syntax.FortranTokenMarker

public class FortranTokenMarker

extends TokenMarker

Custom TokenMarker for UNISYS's ASCII FORTRAN 77. Characteristics of this dialect are:

• Fixed column format, with
  • comment character ( 'C'|'c'|'*' ) in column 1,
  • labels (numeric) in column 1-5,
  • continuation character ( any nonblank ) in column 6,
  • logical end of line after column 72.
• Nonstandard block comment character ( '@' ) in any column,
• Some nonstandard functions: BITS, BOOL, INDEX, TRMLEN

It should be easy enough to adapt this class for minor variations in the dialect so long as the format is the classic fixed column format. As this scanner is highly optimized for the fixed column format, it is probably not readily adaptable for freeform FORTRAN code.

Method Detail

markTokensImpl

public byte markTokensImpl(byte token,
                           javax.swing.text.Segment line,
                           int lineIndex)

Implementation of code to mark tokens.

Specified by:

markTokensImpl in class TokenMarker

Parameters:

token - The initial token type for this line

line - The line to be tokenized

lineIndex - The index of the line in the document, starting at 0

Returns:

The initial token type for the next line

getKeywords

public static KeywordMap getKeywords()

Return the keyword map. It's lazily initialized on the first call.
