示例1: ExecuteLine
//.........这里部分代码省略.........
bool found = CompleteFileName( file);
if( !found)
{
file = fileRaw;
CompleteFileName( file);
}
ExecuteFile( file);
return CC_OK;
}
// statement -> execute it
executeLine.clear(); // clear EOF (for executeLine)
executeLine.str( line + "\n"); // append new line
RefDNode theAST;
try {
Guard<GDLLexer> lexer;
// LineContinuation LC
// conactenate the strings and insert \n
// the resulting string can be fed to the lexer
// print if expr parse ok
int lCNum = 0;
for(;;)
{
lexer.Reset( new GDLLexer(executeLine, "", callStack.back()->CompileOpt()));
try {
// works, but ugly -> depends from parser detecting an error
// (which it always will due to missing END_U token in case of LC)
//lexer->Parser().SetCompileOpt(callStack.back()->CompileOpt());
lexer.Get()->Parser().interactive();
break; // no error -> everything ok
}
catch( GDLException& e)
{
int lCNew = lexer.Get()->LineContinuation();
if( lCNew == lCNum)
// throw; // no LC -> real error
