IDA version compatibility

[klefo0]

I have two version IDA, 7.6 and 8.3
I tried to use the plugin in both versions, nothing happen when i used hotkey (Shift-A) like in this script

void __fastcall game_matrix_render(__int64 a1)
{
  int v2; // eax
  float v3; // xmm2_4
  __int64 v4; // rdx
  float v5; // xmm4_4
  __int128 v6; // xmm1
  float v7; // xmm3_4
  __int64 v8; // rcx
  __int64 v9; // rax
  __int128 v10; // xmm0
  __int64 v11; // r8
  int v12; // ecx
  int v13; // er9
  int v14; // er9
  windowSize *window_size; // rcx

  (*(*a1 + 80i64))(a1, (right_axis * bottom_axis));
  v2 = right_axis;
  v3 = 0.0;
  if ( right_axis > 0.0 )
  {
    v4 = 0i64;
    v5 = bottom_axis;
    do
    {
      v6 = 0i64;
      if ( v5 > 0.0 )
      {
        v7 = v3 + 1.0;
        v8 = 48 * v4;
        do
        {
          v9 = *(a1 + 120);
          v10 = v6;
          *&v10 = *&v6 + 1.0;
          ++v4;
          *(v8 + v9 + 4) = v6;
          *(v8 + v9 + 12) = v6;
          *(v8 + v9 + 36) = v6;
          v6 = v10;
          *(v8 + v9 + 20) = v10;
          *(v8 + v9 + 28) = v10;
          *(v8 + v9 + 44) = v10;
          *(v8 + v9) = v3;
          *(v8 + v9 + 8) = v7;
          *(v8 + v9 + 16) = v3;
          *(v8 + v9 + 24) = v3;
          *(v8 + v9 + 32) = v7;
          *(v8 + v9 + 40) = v7;
          v8 += 48i64;
          v5 = bottom_axis;
        }
        while ( bottom_axis > *&v10 );
        v2 = right_axis;
      }
      v3 = v3 + 1.0;
    }
    while ( v2 > v3 );
  }
  glEnableClientState(GL_COLOR_ARRAY);
  if ( *(a1 + 152) + *(a1 + 156) || CURSE <= 0 || (*init & 2) == 0 )
  {
    window_size = *(a1 + 104);
    *(a1 + 176) = window_size->width;
    *(a1 + 180) = window_size->height;
    *(a1 + 168) = 0i64;
  }
  else
  {
    v11 = *(a1 + 104);
    v12 = right_axis * *(a1 + 112);
    v13 = *(a1 + 116);
    *(a1 + 176) = v12;
    v14 = bottom_axis * v13;
    *(a1 + 180) = v14;
    *(a1 + 168) = (*(v11 + 16) - v12) / 2;
    *(a1 + 172) = (*(v11 + 20) - v14) / 2;
  }
  glViewport(*(a1 + 168), *(a1 + 172), *(a1 + 176), *(a1 + 180));
  glMatrixMode(GL_MODELVIEW);
  glLoadIdentity();
  glMatrixMode(GL_PROJECTION);
  glLoadIdentity();
  gluOrtho2D(0.0, right_axis, bottom_axis, 0.0);
}

The a1 variable should have a struct for it, but the plugin not doing anything.
Can you show me how to use it in detail, or is it plugin work from the older version?

README is a bit outdated, sorry about that... There is no longer default hotkey assigned, one should assign it themselves in Options->shortcuts. Hotkeys' names are phrank::item_analyzer (shift-A in README) and phrank::tfg_printer

[klefo0]

Thanks, I have set the hotkey, the plugin worked. Now it throws errors

Traceback (most recent call last):

Do you have any idea?

[Mizari]

I think that hexrays assumes that all objects compared with cfunc are cfunc too, which is false in this case. Did you try it in 8.3? I didn't test phrank there... I fixed this bug, please check if it works now.
