Variable: ebnf-eps-header

ebnf-eps-header is a customizable variable defined in ebnf2ps.el.gz.

Value

nil

Documentation

Specify EPS header.

The value should be a string, a symbol or nil.

String is inserted unchanged.

For symbol bounded to a function, the function is called and should return a string. For symbol bounded to a value, the value should be a string.

If symbol is unbounded, it is silently ignored.

Empty string or nil mean that no header will be generated.

Note that when the header action comment (;H in EBNF syntax) is specified, the string in the header action comment is processed and, if it returns a non-empty string, it's used to generate the header. The header action comment accepts the following formats:

   %% prints a % character.

   %H prints the ebnf-eps-header(var)/ebnf-eps-header(fun) value.

   %F prints the ebnf-eps-footer(var)/ebnf-eps-footer(fun) (which see) value.

Any other format is ignored, that is, if, for example, it's used %s then %s characters are stripped out from the header. If header action comment is an empty string, no header is generated until a non-empty header is specified or ebnf-eps-header(var)/ebnf-eps-header(fun) has a non-empty string value.

This variable was added, or its default value changed, in Emacs 22.
