  40. <h1 id="supportedplatforms">Supported platforms</h1>
  41. <p>To verify code portability, I selected the following platforms and languages:</p>
  42. <ul>
  43. <li>C++: Linux, macOS, OpenWrt, Windows</li>
  44. <li>JavaScript: Chrome, Firefox, Safari</li>
  45. <li>Kotlin: Android</li>
  46. <li>Python: Linux, macOS, Windows</li>
  47. <li>Swift: iOS, macOS</li>
  48. </ul>
  49. <p>I created a simple "Hello World" example for each language to understand the basic requirements of each platform.</p>
  50. <p>By the way, OpenWrt turned out the most complex platform to create "Hello World" for, because my TP-Link TL-MR3020 r1 router is considered obsolete since 2018. I had to use the old 17.01.7 firmware, which took about three weeks.</p>
  51. <h1 id="anchorlanguageandlimitedlanguagemodel">Anchor language and limited language model</h1>
  52. <p>For the whole month I was asking myself the same question: "Which language should I choose as a starting point to convert to other languages from?" Initial considerations were pointing me to C++ due to strong types. However, as soon as I found out Python has Type hints, I chose Python.</p>
  53. <p>Python is good because:</p>
  54. <ul>
  55. <li>one can specify a type with Type hints</li>
  56. <li>Python has portability across Linux, macOS, Windows out of the box</li>
  57. <li>pip simplifies distribution of the language conversion instrument</li>
  58. <li>Python does not require a separate compilation step, which speeds up development</li>
  59. </ul>
  60. <p>However, not every Python code will suite the language conversion instrument under development. Only the code that satisfies the constraints of the <code>Limited language model</code>.</p>
  61. <p>Limited language model is a subset of Python with various restrictions in both syntax and a set of available functions. Here is a glimpse of those restrictions, the image below depicts Python to C++ conversion result:</p>

  63. <h1 id="aprilplans">April plans</h1>
  64. <p>I'm going to write game logic for "Memory" in Python and convert it to C++ by the instrument under development.</p>
