Hello everyone,
I tried to call SageMath from a java program using the Class
ProcessBuilder. This code success to launch SageMath but when i want to use
the InputStream to interact with Sage (For example a simple code 1+2) it
does not work. iSageMath runs without sending the result of 1+2.
Thank you.
ProcessBuilder pb = new
ProcessBuilder("C:\\Users\\Meryem\\AppData\\Local\\SageMath
9.2\\runtime\\bin\\mintty.exe", "-t","SageMath 9.2 Console", "-i",
"sagemath.ico", "/bin/bash", "--login", "-c", "/opt/sagemath-9.2/sage");
try
{
Process p = pb.start();
OutputStream stdin = p.getOutputStream();
InputStream stdout = p.getInputStream();
//InputStream stderr = p.getErrorStream();
BufferedReader reader = new BufferedReader(new
InputStreamReader(stdout));
BufferedWriter writer = new BufferedWriter(new
OutputStreamWriter(stdin));
writer.write("1+2" + "\n");
writer.flush();
writer.close();
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
p.waitFor();
p.destroy();
} catch (IOException e) {
System.out.println("I/O error:" + e.getMessage());
} catch (Exception e) {
System.out.println("Error:" + e.getMessage());
}
return null;
}
