From: Morgan Deters Date: Mon, 15 Nov 2010 22:57:14 +0000 (+0000) Subject: Pretty-printer infrastructure created (in src/printer) and SMT-LIBv2 printer X-Git-Tag: cvc5-1.0.0~8735 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5e5956d492ab18b5b4d4bb51117ac760867a525d;p=cvc5.git Pretty-printer infrastructure created (in src/printer) and SMT-LIBv2 printer implemented. This new infrastructure removes support for pretty-printing (even in the AST language) an Expr with reference count 0. Previously, this was supported in a few places internally to the expr package, for example in NodeBuilder. (Now, a NodeBuilder cannot be prettyprinted, you must extract the Node before printing it.) --- diff --git a/config/mkbuilddir b/config/mkbuilddir index 252f17ea5..1ed5eda92 100755 --- a/config/mkbuilddir +++ b/config/mkbuilddir @@ -21,6 +21,11 @@ fi target=$1 build_type=$2 +: {$as_echo:=echo} +: {$RM:=rm -f} +: {$MKDIR_P:=mkdir -p} +: {LN_S:=ln -s} + $as_echo "Setting up builds/$target/$build_type..." $RM config.log config.status confdefs.h builds/Makefile $MKDIR_P "builds/$target/$build_type" diff --git a/src/Makefile.am b/src/Makefile.am index 8224deb8f..48e052eef 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -17,7 +17,7 @@ AM_CPPFLAGS = \ -I@srcdir@/include -I@srcdir@ -I@builddir@ AM_CXXFLAGS = -Wall -Wno-unknown-pragmas $(FLAG_VISIBILITY_HIDDEN) -SUBDIRS = lib expr util context theory prop smt . parser main +SUBDIRS = lib expr util context theory prop smt printer . parser main lib_LTLIBRARIES = libcvc4.la noinst_LTLIBRARIES = libcvc4_noinst.la @@ -35,6 +35,7 @@ libcvc4_la_LIBADD = \ @builddir@/context/libcontext.la \ @builddir@/prop/libprop.la \ @builddir@/prop/minisat/libminisat.la \ + @builddir@/printer/libprinter.la \ @builddir@/smt/libsmt.la \ @builddir@/theory/libtheory.la \ @builddir@/lib/libreplacements.la @@ -44,6 +45,7 @@ libcvc4_noinst_la_LIBADD = \ @builddir@/context/libcontext.la \ @builddir@/prop/libprop.la \ @builddir@/prop/minisat/libminisat.la \ + @builddir@/printer/libprinter.la \ @builddir@/smt/libsmt.la \ @builddir@/theory/libtheory.la \ @builddir@/lib/libreplacements.la diff --git a/src/expr/expr_template.h b/src/expr/expr_template.h index be089bca8..2e27b4f66 100644 --- a/src/expr/expr_template.h +++ b/src/expr/expr_template.h @@ -648,15 +648,23 @@ public: ExprSetLanguage(OutputLanguage l) : d_language(l) {} inline void applyLanguage(std::ostream& out) { - out.iword(s_iosIndex) = int(d_language); + // (offset by one to detect whether default has been set yet) + out.iword(s_iosIndex) = int(d_language) + 1; } static inline OutputLanguage getLanguage(std::ostream& out) { - return OutputLanguage(out.iword(s_iosIndex)); + long& l = out.iword(s_iosIndex); + if(l == 0) { + // set the default language on this ostream + // (offset by one to detect whether default has been set yet) + l = s_defaultLanguage + 1; + } + return OutputLanguage(l - 1); } static inline void setLanguage(std::ostream& out, OutputLanguage l) { - out.iword(s_iosIndex) = int(l); + // (offset by one to detect whether default has been set yet) + out.iword(s_iosIndex) = int(l) + 1; } };/* class ExprSetLanguage */ @@ -664,7 +672,7 @@ public: ${getConst_instantiations} -#line 659 "${template}" +#line 676 "${template}" namespace expr { diff --git a/src/expr/metakind_template.h b/src/expr/metakind_template.h index cb9730d34..c4604d40e 100644 --- a/src/expr/metakind_template.h +++ b/src/expr/metakind_template.h @@ -88,11 +88,6 @@ struct NodeValueCompare { inline static size_t constHash(const ::CVC4::expr::NodeValue* nv); };/* struct NodeValueCompare */ -struct NodeValueConstPrinter { - inline static void toStream(std::ostream& out, - const ::CVC4::expr::NodeValue* nv); -}; - /** * "metakinds" represent the "kinds" of kinds at the meta-level. * "metakind" is an ugly name but it's not used by client code, just @@ -264,6 +259,12 @@ ${metakind_constHashes} } } +struct NodeValueConstPrinter { + inline static void toStream(std::ostream& out, + const ::CVC4::expr::NodeValue* nv); + inline static void toStream(std::ostream& out, TNode n); +}; + inline void NodeValueConstPrinter::toStream(std::ostream& out, const ::CVC4::expr::NodeValue* nv) { Assert(nv->getMetaKind() == kind::metakind::CONSTANT); @@ -275,6 +276,10 @@ ${metakind_constPrinters} } } +inline void NodeValueConstPrinter::toStream(std::ostream& out, TNode n) { + toStream(out, n.d_nv); +} + /** * Cleanup to be performed when a NodeValue zombie is collected, and * it has CONSTANT metakind.
