Special Types of Attribute Grammars
- S-attributed grammar : a simple type of attribute grammar, using only synthesized attributes, but no inherited attributes.
- L-attributed grammar : inherited attributes can be evaluated in top-down parsing.
- LR-attributed grammar : an L-attributed grammar whose inherited attributes can also be evaluated in bottom-up parsing.
- ECLR-attributed grammar : equivalent classes can also be used to optimize the evaluation of inherited attributes.

Famous quotes containing the words special, types, attribute and/or grammars:
“A special kind of beauty exists which is born in language, of language, and for language.”
—Gaston Bachelard (1884–1962)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“Essential truth, the truth of the intellectualists, the truth with no one thinking it, is like the coat that fits tho no one has ever tried it on, like the music that no ear has listened to. It is less real, not more real, than the verified article; and to attribute a superior degree of glory to it seems little more than a piece of perverse abstraction-worship.”
—William James (1842–1910)
“The violent illiteracies of the graffiti, the clenched silence of the adolescent, the nonsense cries from the stage-happening, are resolutely strategic. The insurgent and the freak-out have broken off discourse with a cultural system which they despise as a cruel, antiquated fraud. They will not bandy words with it. Accept, even momentarily, the conventions of literate linguistic exchange, and you are caught in the net of the old values, of the grammars that can condescend or enslave.”
—George Steiner (b. 1929)
