Support for lvgl v9

[stwirth]

I'm seeing this definition in fonts included in the lvgl repo master branch:

/*Initialize a public general font descriptor*/
#if LVGL_VERSION_MAJOR >= 8
const lv_font_t lv_font_montserrat_18 = {
#else
lv_font_t lv_font_montserrat_18 = {
#endif
    .get_glyph_dsc = lv_font_get_glyph_dsc_fmt_txt,    /*Function pointer to get glyph's data*/
    .get_glyph_bitmap = lv_font_get_bitmap_fmt_txt,    /*Function pointer to get glyph's bitmap*/
    .line_height = 21,          /*The maximum line height required by the font*/
    .base_line = 4,             /*Baseline measured from the bottom of the line*/
#if !(LVGL_VERSION_MAJOR == 6 && LVGL_VERSION_MINOR == 0)
    .subpx = LV_FONT_SUBPX_NONE,
#endif
#if LV_VERSION_CHECK(7, 4, 0) || LVGL_VERSION_MAJOR >= 8
    .underline_position = -1,
    .underline_thickness = 1,
#endif
    .dsc = &font_dsc           /*The custom font data. Will be accessed by `get_glyph_bitmap/dsc` */
};

However, when I generate a font using this repo (npx github:lvgl/lv_font_conv ...) then the definition looks like this:

/*Initialize a public general font descriptor*/
#if LV_VERSION_CHECK(8, 0, 0)
const lv_font_t inter_tight_bold_18 = {
#else
lv_font_t inter_tight_bold_18 = {
#endif
    .get_glyph_dsc = lv_font_get_glyph_dsc_fmt_txt,    /*Function pointer to get glyph's data*/
    .get_glyph_bitmap = lv_font_get_bitmap_fmt_txt,    /*Function pointer to get glyph's bitmap*/
    .line_height = 23,          /*The maximum line height required by the font*/
    .base_line = 5,             /*Baseline measured from the bottom of the line*/
#if !(LVGL_VERSION_MAJOR == 6 && LVGL_VERSION_MINOR == 0)
    .subpx = LV_FONT_SUBPX_NONE,
#endif
#if LV_VERSION_CHECK(7, 4, 0) || LVGL_VERSION_MAJOR >= 8
    .underline_position = -3,
    .underline_thickness = 1,
#endif
    .dsc = &font_dsc           /*The custom font data. Will be accessed by `get_glyph_bitmap/dsc` */
};

So it seems the generation of the version check needs an update?

I'm also getting

error: unknown type name ‘lv_font_fmt_txt_glyph_cache_t’
 2348 | static  lv_font_fmt_txt_glyph_cache_t cache;
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Is there a version of this converter that supports the master version of lvgl?

Thank you for reporting it. I've just created this PR: #97 Could you test it?
