Statement Description
case-sensitive= [Y | N] Defines the case sensitivity for the language. This
statement must be the first or second statement
within the section.
idchars=start_id_chars after_id_chars Defines the characters that are the start of a valid
identifier and additional valid characters that may
follow. This statement must be the first or second
statement within the section. You may use a dash
(-) character to specify a range, for example, A-Z
specifies uppercase letters. To specify a dash or
backslash (\) character as a valid word character,
place a backslash before the character.
styles= style Defines zero or more styles. See Table of style Val-
ues below for a list of available styles.
mlcomment= start_symbol end_symbol
[nesting] [followedby idchars] [colorname]
Defines a multi-line comment. start_symbol and
end_symbol define strings which start and end the
comment. Specify nesting if the lexer should look
for another occurrence of start_symbol when
looking for the end comment symbol. The fol-
lowedby idchars is used to require certain char-
acters to follow start_symbol. You can use a
dash (-) character to specify a range, such as A-Z,
which specifies uppercase letters. To specify a
dash (-) or backslash (\) character as a valid word
character, place a backslash before the character.
followedby is ignored when the html style is spe-
cified. Currently, start_symbol and end_symbol
may not be valid identifiers. No more than four
multi-line comments may be defined. colorname
can be used to indicate that a different color such
as keyword color be used instead of comment color
when a match is found. colorname may be
keywordcolor, numbercolor, stringcolor, com-
mentcolor, ppkeywordcolor, linenumcolor, sym-
bol1color, symbol2color, symbol3color, or sym-
bol4color.
mlcomment= start_symbol start_col
[checkfirst|leading] end_symbol [lastchar]
Defines a multi-line comment. This construct was
designed to handle comments for the ATLAS lan-
guage. start_symbol and end_symbol define
strings which start and end the comment.
start_symbol is only considered the start of a
comment if it appears in column start_col.
checkfirst specifies that the lexer should check if
