Generic modes are simple major modes with basic support for
comment syntax and Font Lock mode. To define a generic mode, use the
define-generic-mode. See the file generic-x.el
for some examples of the use of
This macro defines a generic mode command named mode (a symbol,
not quoted). The optional argument docstring is the
documentation for the mode command. If you do not supply it,
define-generic-mode generates one by default.
The argument comment-list is a list in which each element is
either a character, a string of one or two characters, or a cons cell.
A character or a string is set up in the mode’s syntax table as a
“comment starter”. If the entry is a cons cell, the CAR is set
up as a “comment starter” and the CDR as a “comment ender”.
nil for the latter if you want comments to end at the end
of the line.) Note that the syntax table mechanism has limitations
about what comment starters and enders are actually possible.
See Syntax Tables.
The argument keyword-list is a list of keywords to highlight
font-lock-keyword-face. Each keyword should be a string.
Meanwhile, font-lock-list is a list of additional expressions to
highlight. Each element of this list should have the same form as an
font-lock-keywords. See Search-based Fontification.
The argument auto-mode-list is a list of regular expressions to
add to the variable
auto-mode-alist. They are added by the execution
define-generic-mode form, not by expanding the macro call.
Finally, function-list is a list of functions for the mode
command to call for additional setup. It calls these functions just
before it runs the mode hook variable
