Free form Fortran syntax highlighting

  • Version 6.9.1 of Notepad++ introduced built-in syntax highlighting for free-format Fortran, but it does not recognise a line with a ‘C’ or ‘c’ in column 1 as a comment, only the remainder of a line after ‘!’.

    Can this be fixed, or should I continue using UDL instead?

  • comment line starting with a ‘c’ in column 1 is only in fixed-form FORTRAN, not in free format Fortran. Are you sure you’re using the correct highlighting scheme?

    Note that Notepad++ currently use free format highlighting for files with extension “.f”.
    You can add this extension to the “custom extension” of fixed format FORTRAN to change this default behavior.
