打印线尺寸的限制

如何解决打印线尺寸的限制

我发现了一个相当奇怪的效果。以下应用在控制台和esp32上的运行方式不同。

main :
  loop ::= 99
  text  := ""
  stamp := "1234567890"
  loop.repeat :
    text += stamp
  print ("$text")
 

CLI：

micrcx@micrcx-desktop:~/toit_apps/Hsm3/tests$ toit execute test_str.toit
123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890

esp32：

micrcx@micrcx-desktop:~/toit_apps/Hsm3/tests$ toit run test_str.toit
2021-06-02T16:38:19.837338Z: <process initiated>
2021-06-02T16:38:20.046599Z: <process terminated - exit code: 0>

如果将 loop ::= 99 替换为 loop ::= 98，则应用程序将正常工作在 esp32 上：

    micrcx@micrcx-desktop:~/toit_apps/Hsm3/tests$ toit run test_str.toit
    2021-06-02T16:45:56.925573Z: <process initiated>

最终我发现了这个神奇的数字。可以打印到 esp32 的最大行长度为 981。我发现的错误是随机的还是真的有限制？
