well; i haven't seen it.
it's actually that simple

Scalar Interpreter::Eval(const char *code, bool croak) {
   Scalar retval;
   retval.Attach(eval_pv(code, croak));
   return retval;
}

void PerlObj::RedirectStdout(const std::string & filename) {
    std::string code = "";
    
    code += "open(YAPPPSSTDOUTSAVE, \">&STDOUT\");";
    code += "open(YAPPPSSTDOUTFILE, \">";
    code += MakeUnixFilename(filename);
    code += "\") or die \"Unable to override STDOUT!\";";
    code += "open(STDOUT, \">&YAPPPSSTDOUTFILE\") or \
            die \"Unable to override STDOUT!\";";
        
    m_perl->Eval(code.c_str(), true);
    m_redirectstdout = true;
}

void PerlObj::RedirectStdin(const std::string & filename) {
    std::string code = "";
    
    code += "open(YAPPPSSTDINSAVE, \"<&STDIN\");";
    code += "open(YAPPPSSTDINFILE, \"<";
    code += MakeUnixFilename(filename);
    code += "\") or die \"Unable to override STDIN!\";";
    code += "open(STDIN, \"<&YAPPPSSTDOUTFILE\") or \
            die \"Unable to override STDIN!\";";
    
    m_perl->Eval(code.c_str(), true);
    m_redirectstdin = true;
}

void PerlObj::ResetStdio() {
    std::string code = "";
    if(m_redirectstdin) {        
        code += "open(STDIN, \"<&YAPPPSSTDINSAVE\");";
        code += "close(YAPPPSSTDINFILE);";
        m_redirectstdin = false;
    }
    if(m_redirectstdout) {        
        code += "open(STDOUT, \">&YAPPPSSTDOUTSAVE\");";
        code += "close(YAPPPSSTDOUTFILE);\n";
        m_redirectstdout = false;
    }
    if(code != "")
        m_perl->Eval(code.c_str(), true);

and no i can just call "chdir" to set the workingdirectory because it will just set the wd of the current interpreter.
It's fun! :) i'm happy!

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
