/* atom list for CSS pseudo-classes */

/*
 * This file contains the list of nsIAtoms and their values for CSS
 * pseudo-classes.  It is designed to be used as inline input to
 * nsCSSPseudoClasses.cpp *only* through the magic of C preprocessing.
 * All entries must be enclosed in the macros CSS_PSEUDO_CLASS,
 * CSS_STATE_DEPENDENT_PSEUDO_CLASS, or CSS_STATE_PSEUDO_CLASS which
 * will have cruel and unusual things done to them.  The entries should
 * be kept in some sort of logical order.  The first argument to
 * CSS_PSEUDO_CLASS is the C++ identifier of the atom.  The second
 * argument is the string value of the atom.  The third argument is the
 * name of the preference controlling whether the pseudo-class is
 * recognized by the parser, or the empty string if it's unconditional.
 *
 * CSS_STATE_DEPENDENT_PSEUDO_CLASS and CSS_STATE_PSEUDO_CLASS also take
 * the name of the state bits that the class corresponds to.  Only one
 * of the bits needs to match for a CSS_STATE_PSEUDO_CLASS to match;
 * CSS_STATE_DEPENDENT_PSEUDO_CLASS matching depends on a customized per-class
 * algorithm which should be defined in SelectorMatches() in
 * nsCSSRuleProcessor.cpp.
 *
 * If CSS_STATE_PSEUDO_CLASS is not defined, it'll be automatically
 * defined to CSS_STATE_DEPENDENT_PSEUDO_CLASS;
 * if CSS_STATE_DEPENDENT_PSEUDO_CLASS is not defined, it'll be
 * automatically defined to CSS_PSEUDO_CLASS.
