Slick EDIT V3.3 - Manual (Page 515)

Statement Description
the line is a comment before determining the color
coding of symbols in the line. When the checkfirst
option is specified, start_symbol is limited to one
character in length. leading specifies that symbol
is considered a line comment only if it appears as
the first non-blank character. Space or tab charac-
ters are considered blanks. Currently, end_symbol
may not be a valid identifier. lastchar specifies that
end_symbol must appear as the last character on
a line to terminate the comment. No more than two
multi-line comments may be defined.
mlckeywords= [keyword ] [keyword ] ... Defines keywords for the last mlcomment state-
ment. When one of these keywords follows the
start_symbol defined for the last mlcomment
statement, the keyword color is used to color the
comment instead of comment color. Keywords do
not have to be valid identifiers. This statement is
useful for tag languages like HTML. See the HTML
definition in the file vslick.vlx for an example.
keywordattrs= [mlckeyword] [attribute ] [at-
tribute ] ...
Defines attributes for the mlckeyword specified
which belongs to the last mlcomment statement.
Currently this statement only supports HTML syntax
attributes and requires that the HTML style be spe-
cified. For example, keywordattrs=SCRIPT LAN-
GUAGE SRC
linecomment= [symbol ] [col | col+ |
start_col - end_col] [checkfirst|leading]
Defines a line comment. symbol defines the char-
acter(s) which start this line comment. If no column
limits are specified, the remainder of the line is con-
sidered a comment regardless of where symbol
appears. A plus sign (+) after a column specifies an
unlimited end_col. checkfirst specifies that the
lexer should check if the line is a comment before
determining the color coding of symbols in the line.
When the checkfirst option is specified, symbol is
limited to one character in length. If symbol is not
specified, all characters will be ignored at or after
the column specified (ex. linecoment=73+). This is
useful for Fortran which requires that all characters
at or after column 73 be ignored. leading specifies
that symbol is considered a line comment only if it
appears as the first non-blank character. Space or
tab characters are considered blanks.
