some question

Sylfir

Hello, i used ZeroBrane with love 2D before. This LuaRT studio is interesting for me but there are som questions i have.
1) Can i build exe from the project?
2) Is there any way to create something like a canvas picture where i can draw stuff by using functions like rectangle, circle, text, line?
3) Is there any possibility to enhance the richtext edit component to use some kind of coloring to simulate syntax highlight for my own scripting language?

Samir

Hi Sylfir and welcome to the LuaRT Community forums !

1) You can build an executable for your project but for now you will need to use the rtc compiler from the command Line (it ils planned and will be possible from the IDE in a next release)

2) For now there is no Canva component available in the ui module, sorry.

3) Yes syntax highlighting from the Edit widget should be possible using the Edit.selection property. I have a near working example that try to demonstrate it. If you have some interest in it I can make it available. Any help would be much appreciated 😋

Regards,

Samir

3) This would be awesome. I can look at it.

One more
4) The UI components are based on wxWidgets or something that you make on your own?

Samir

Ok I will publish the syntax highlighting example very soon

4) The ui module does not rely on a third party gui library to preserve compactness of LuaRT. I built it from scratch using pure C WinAPI.

Samir

The syntax highlighting example file is corrupt on my SSD.....
I can't make it available right away, I'll have to rewrite it... 😥

Samir

Here is a link to the syntax highlighting example using a new derived widget based on an Edit : [Login to see the link]

This example demonstrates a simple technique for obtaining syntax highlighting for an Edit object.

However, for the moment LuaRT does not allow disabling automatic scrolling when changing the current selection (with the Edit.selection property). When using long text, the Edit widget will scroll oddly very fast.

This is not a bug, but next version of LuaRT will permit to enable/disable automatic scrolling when changing the current selection in an Edit widget.

Hello. I started working with your LuaRT library. I experiment from time to time. Everything looks great so far. I don't think it will be very difficult since it is simple and understandable to use. Thank you again for creating such a library. I usually try to write Lua programs with Notepad++, but I downloaded LuaRT Studio and will try to get used to it. Do you intend to further develop LuaRT Studio? Maybe in the future you can add a GUI interface with an interface with Buttons, Checkboxes, TexBoxes.

and the other question;
when i run the code below;

local ui = require "ui"

-- create a simple window 
local win = ui.Window("Window.cursor sample", 320, 200)
win:show()

win:status("Hover the window to view the 'hand' cursor !")

-- set the mouse cursor when hovering the window
win.cursor = "hand"

-- update user interface
repeat
	ui.update()
until not win.visible

and
"Hover the window to view the 'hand' cursor !" When I press the right click button of the mouse anywhere in the menu bar that says as folowing

; executing: GOTO EXIT
- no label found: EXIT
; executing: ENDIF
- Unexpected ENDIF found, without preceding IF.
To prevent unpredictable behavior, the script is stopped.

Why might it be giving this error?

Samir

Hi,

A gui builder for LuaRT is something I want to add to LuaRT Studio, but this will be possible after a certain degree of maturity of the ui module.

Very strange error you are reporting ! It seems like a Lua bytecode error. I have to dig more into it to understand why this kind of error has been thrown.

Can you tell me where this message is printed ?

Thank you for the report !

Samir

The error you have reported is related to the NppExec plugin you are using to run LuaRT from Notepad++

Please try to run the same script from the command line or by double clicking on the script file in the Windows explorer, and tell me if any error occurs.

As you said, I think it's a problem with notepad++ because when this file I'm working with is run in the console with the "wluart new 1.lua" command, an error does not occur. 🙂

cos00kun

but this time, when I right click the mouse on the area I mentioned, the window closes. however, it should not be closed.
I tried with Luart Studio, even if it doesn't give an error, the window closes. Maybe it is programmed that way, but still, the window should not close when the submenu I mentioned is clicked with the mouse. 🙂

Samir

Yes you are right the Window should not close.

Thank you for the report !

cos00kun

I'm glad I made a contribution.

cos00kun

hi again..
I've already started working out the exercises on this website. I am happy for that. 🙂 🙂
I hope I do not overwhelm you with my questions, but the checkbox in the following section ([Login to see the link]) does not work by clicking the mouse. The error I mentioned before also occurs here (I mentioned in the above messages. When we run the program, when we click on the bar that appears at the bottom, the window closes).
I wanted to talk about these two errors. 🙏

Hi cos00kun,

I need more informations for this one :

Do you use the x86 or x64 version or LuaRT ?
What is your Windows version ?

Regards,

Samir

I edited it as follows.. I removed the "self.checked = true" option in the function checkbox:onClick() function and added the following lines instead;

	if (self.checked == true) then self.checked = true end
	if (self.checked == false) then self.checked = false end

at least i can tick the checkbox now 😀

hi.. I am using x64 based windows 11 system.

cos00kun

I just tried it with X64-based Windows 10 on my laptop at home, the result is the same.

Samir

Ok thank you again !
