in reply to Perl Embedded: Setting %ENV, STDIN and Workingdirectory

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!
