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. %track prog kelbt = { version = %{version} url = http://www.complang.org/kelbt/ regex = kelbt-(__VER__)\.tar\.gz } %prep %setup -q %build CC="%{l_cc}" \ CXX="%{l_cxx}" \ CFLAGS="%{l_cflags -O}" \ CXXFLAGS="%{l_cxxflags -O}" \ CPPFLAGS="%{l_cppflags}" \ LDFLAGS="%{l_ldflags}" \ ./configure \ --prefix=%{l_prefix} %{l_make} %{l_mflags -O} %install rm -rf $RPM_BUILD_ROOT %{l_make} %{l_mflags} install \ prefix=$RPM_BUILD_ROOT%{l_prefix} strip $RPM_BUILD_ROOT%{l_prefix}/bin/* >/dev/null 2>&1 || true %{l_rpmtool} files -v -ofiles -r$RPM_BUILD_ROOT %{l_files_std} %files -f files %clean rm -rf $RPM_BUILD_ROOT @
