https://github.com/deividAlfa/UGUI adds UTF-8 support, new font structure to allow font stripping, ranges...

Given this project seems no longer alive, I'm providing the fork for anyone who might be searching new enhancements... https://github.com/deividAlfa/UGUI

Nice, UTF-8 support is great!

I also have a fork, https://github.com/0x3333/UGUI, with those features:

• Fonts, Components, Colors have been externalized to a separated file
• Pseudo Theme created(See ugui_theme.h)
• Added flush function. In case the display driver uses Framebuffer, this function will be called after UG_Update is called
• Prefixed all defines with UGUI_
• Touch support is optional using UGUI_USE_TOUCH define
• Added UGUI_USE_COLOR_BW for monochromatic displays, also added theme support
• Added X11 Simulator. Based on the fork https://github.com/MarioIvancic/UGUI. Tested only on MacOS 10.14.
• Added Simulation config
• Added Simulation example
• Added Function to convert from RGB565 to RGB888
• Added a check to UG_DrawRoundFrame, draw a rect frame in case radius 0
• Added ProgressBar object
• Console support is optional using UGUI_USE_CONSOLE define.
• Created a UG_DEVICE struct to hold device information.

Nice! Will have a look, shouldn't be too hard to add the code. This library deserves more attention!

[deividAlfa]

I've checking your code. The externalization actually complicates things. Instead of simply including ugui.h, you have to include:

#include "ugui.h" #include "ugui_button.h" #include "ugui_checkbox.h" #include "ugui_textbox.h" #include "ugui_image.h" #include "ugui_progress.h"

Which is a poor implementation. it should be simpler. Giving some issues due that...

Sure, I had this in my backlog for a while. Thanks

[deividAlfa]

I fixed it in a simple way: Adding the includes after the defines and typedefs ugui.h:455 #define UG_STATUS_WAIT_FOR_UPDATE (1<<0) #include "ugui_button.h" #include "ugui_checkbox.h" #include "ugui_fonts_data.h" #include "ugui_image.h" #include "ugui_progress.h" #include "ugui_textbox.h"

This works perfectly, no more messsing with includes. I'm almost done at merging my code.

[deividAlfa]

Finished! I have some simple demos using current uGUI version here: https://github.com/deividAlfa/ST7789-STM32-uGUI

Also check my ttf2ugui fork to generate fonts using the new structure. I ported the old fonts, adding a bit to disable UTF8 when these fonts are selected, as they use codepage 850 encoding.

It is missing the simulator files, like ugui_sim_x11.c.

[deividAlfa]

Yep, ugui_sim.c was left when uploading the files. Fixed

[0x3333]

Me again, missing the X11 sim, ugui_sim_x11.c. Super helpful to debug on Mac or Linux the output(I used it to print my screenshots, see README.md in my fork).

[deividAlfa]

Yeah, I noticed that file too, I was going to update the comment but I was late

[agugu2000]

hey,dude,you still there??I tried your enhancement.A very good job. I've noticed an issue with your program when handling CJK characters whose encoding falls above 0x8000; they fail to display. The problem doesn't seem to lie with the font array itself, but rather with the positioning logic in _UG_GetCharData, specifically the line curr_offset & 0x8000.

[agugu2000]

OK,let my adjust my words:when the font array contains the characters over 0x8000，device will display nothing including any asciis or latin or CJK. when regain the font array without 0x8000+,everything goes fine.

Hope there will be a fix

[deividAlfa]

Yes, it only works with Unicode below 0x8000. I just enabled issues in the repo.

I might extend the range to full Unicode (0-65535).

[agugu2000]

Dude,many many thanks
