%description |
|
Kelbt generates backtracking LALR(1) parsers. Where traditional |
|
LALR(1) parser generators require static resolution of shift/reduce |
|
conflicts, Kelbt generates parsers that handle conflicts by |
|
backtracking at runtime. Kelbt is able to generate a parser for any |
|
context-free grammar that is free of hidden left recursion. Kelbt |
|
is different from other backtracking LR systems in two ways. First, |
|
it introduces a class of actions called undo actions. These actions |
|
are invoked as the backtracker undoes parsing and allow the user |
|
to revert any side effects of forward semantic actions. This makes |
|
it possible to backtrack over language constructs that must modify |
|
global state in preparation for handling context dependencies. |
|
Second, Kelbt enables a user-controlled parsing strategy that |
|
approximates that of generalized recursive-descent parsing with |
|
ordered choice. This makes it easy for the user to resolve language |
|
ambiguities by ordering the grammar productions of a non-terminal |
|
according to precedence. It is approximate in the sense that for |
|
most grammars the equivalent of an ordered choice parsing strategy |
|
is achieved. In cases where productions are parsed out of the order |
|
given, there is a simple grammar transformation that remedies the |
|
problem. |
