[ArduinoCore-mbed] REDIRECT_STDOUT_TO equivalent for stdin

dmazzella · March 16, 2022, 11:55am

Hi,
is there an equivalent way to REDIRECT_STDOUT_TO to capture the stdin?

I am trying to integrate JerryScript on the Portenta H7.
Running scripts works fine, but to enable the "console" (repl) i need to use fgetc

/**
           * Read a line from standard input as a zero-terminated string.
           *
           * @param out_size_p: length of the string
           *
           * @return pointer to the buffer storing the string,
           *         or NULL if end of input
           */
          jerry_char_t *JERRY_ATTR_WEAK
          jerry_port_line_read (jerry_size_t *out_size_p)
          {
            char *line_p = NULL;
            size_t allocated = 0;
            size_t bytes = 0;
          
          
  while (true)
            {
              allocated += 64;
              line_p = realloc (line_p, allocated);

required to enable repl mode

          #include "jerryscript-ext/repl.h"
          
          
#include <string.h>
          
          
#include "jerryscript-port.h"
          #include "jerryscript.h"
          
          
#include "jerryscript-ext/print.h"
          
          
void
          jerryx_repl (const char *prompt_p)
          {
            jerry_value_t result;
          
          
  while (true)
            {
              jerryx_print_string (prompt_p);
          
          
    jerry_size_t length;
              jerry_char_t *line_p = jerry_port_line_read (&length);

Any suggestions?

Thank you,
D.
