Generated path - the beginning slash is missing, is this normal or not? Discrepancies in the documentation

Bugs

What do you want to achieve?

I want the generated code to run error-free!

// IMAGE DATA: assets/boot.png
   const char *ui_img_boot_png = "L:assets/boot.png";

The generated code leads to a fatal error and there is no picture on the display

[  2824][E][vfs_api.cpp:28] open(): assets/boot.png does not start with /

What have you tried so far?

Adding an beginning slash in path fixes the error.

// IMAGE DATA: assets/boot.png
   const char *ui_img_boot_png = "L:/assets/boot.png";

Usage example here

The example below shows how to read from a file:

lv_fs_file_t f;
lv_fs_res_t res;
res = lv_fs_open(&f, "S:folder/file.txt", LV_FS_MODE_RD);
if(res != LV_FS_RES_OK) my_error_handling();

uint32_t read_num;
uint8_t buf[8];
res = lv_fs_read(&f, buf, 8, &read_num);
if(res != LV_FS_RES_OK || read_num != 8) my_error_handling();

lv_fs_close(&f);

This example shows how to read a directory’s content. It’s up to the driver how to mark directories in the result but it can be a good practice to insert a / in front of each directory name.

lv_fs_dir_t dir;
lv_fs_res_t res;
res = lv_fs_dir_open(&dir, "S:/folder");
if(res != LV_FS_RES_OK) my_error_handling();

char fn[256];
while(1) {
    res = lv_fs_dir_read(&dir, fn, sizeof(fn));
    if(res != LV_FS_RES_OK) {
        my_error_handling();
        break;
    }

    /*fn is empty, if not more files to read*/
    if(strlen(fn) == 0) {
        break;
    }

    printf("%s\n", fn);
}

lv_fs_dir_close(&dir);

As practice has shown, It’s up to the driver does not decide anything by himself, and “good practice” must be the rule?

I have a dozen images in my project, and after each export, correcting the code manually is very tiring.
