Incremental parsing is widely used in language-based editors and incremental compilation and interpretive environments. Reparsing of modified input strings is the most frequently performed operation in these environments and its efficiency can greatly affect the success of such environments. This paper describes the introduction of nonterminals as lookahead symbols into an LL parse table to support minimal LL reparsing. This enhancement is then used to produce an efficient incremental LL parser.
