View Full Version : about RUST
Hi Petr,
i refer to your project in https://github.com/petrSchreiber/Calling-Rust-DLL-from-ThinBASIC
when you have time only and if possible to add to the test_lib.tbasic and lib.rs how to pass an array of numbers, and an array of strings, and an array of UDT from thinbasic to Rust DLL and to get it back to thinbasic
the reason is that i want to test the rust dll speed in my example http://www.thinbasic.com/community/showthread.php?12619-Boosting-calculation-speed-using-compilers-DLLs-(such-as-FreeBasic)
and to compare its speed with the freebasic DLL i have used in that example and to the Oxygen module you have used there. of course after increasing the Simpson figure points to thousands so to notice the timings.
the UDTs can be :
Type TBGL_TRGB
r As Byte
g As Byte
b As Byte
End Type
Type TBGL_TVECTOR3F
x As Single
y As Single
z As Single
end type
or as you like more suitable
Thanks

Hi Primo,
sure thing, I am happy you find it interesting.
I will work on it today afternoon and will notify you here once ready :)

Hi Primo,
I think I have it for you ;) I also did a minor cleanup of the whole repository and made it possible to use thinBasic strings without need to convert them to unicode first.
Please have a look here for new ThinBASIC definition:
https://github.com/petrSchreiber/Calling-Rust-DLL-from-ThinBASIC/blob/master/test/test_lib.tbasic#L32
...and calling code:
https://github.com/petrSchreiber/Calling-Rust-DLL-from-ThinBASIC/blob/master/test/test_lib.tbasic#L110
...and here for the Rust code being called:
https://github.com/petrSchreiber/Calling-Rust-DLL-from-ThinBASIC/blob/master/src/user_defined_types.rs
Petr
you are so generous Petr to provide such a detailed code, which without i will never be able to send UDT array to Rust.
i have applied the instructions in README.md: cargo build --release, then i have found the rust_interop.dll in the Release folder. and after running the test_lib.tbasic it display the output in magnificent glory:
9868
but when i press a key to exit the program, the windows 7/x64 display a pop up: thinbasic has stopped to working ...windows is collecting....
your previous package does not display this message.
amazingly with the same DLL thinbasic does not display the error in windows xp/32
Thank you again, tomorrow i will try to run the Simpson figure generator using the Rust DLL according to the info and code you have provided.
Hi Petr
just now i have found that the msg "thinbasic.exe has stopped working" happened only when we want to exit by pressing a key, but there is no error msg when we close the program from the 'X'
this is in windows 7/x64 with thinbasic V1.10.5.0

Hi Primo,
the root cause was mistake on my side - I passed array of two elements, but told Rust it is 10 element array.
Try now, I am pretty confident it will resolve the issue :)
Petr
Thank you Petr
yes it is now works okay like charm
Hi Petr
i have found that sin, cos, tan, sqrt, pow and others are not implemented naturally in rust and while searching there are a lot of chaos, there are other people don't know how to to run the math functions.
if there is something usable from the Rust servers will be great to add to your thinbasic_Rust package
Thanks

Hi Primo,
Rust of course has sin/cos/tan, these are the functions I need and love :)
They are functions of given data types, for example f32 (SINGLE) and f64 (DOUBLE).
Check this snippet:
let angle_deg: f32 = 45.0; // Equivalent of `dim angle_deg as single = 45`
let angle_rad = angle_deg.to_radians(); // Easy conversion to radians
println!("Sinus of {} degrees is {}", angle_deg, angle_rad.sin());
See here what does Rust offer:
https://doc.rust-lang.org/std/primitive.f64.html
This is the link to explore Rust standard library:
https://doc.rust-lang.org/book/second-edition/index.html
...and this is a very neat and complete book about Rust:
https://www.rust-lang.org/en-US/
Primo, what do you think about putting your DLL in Rust to GitHub? I would be happy to contribute, we could learn a lot and share the progress with the thinBasic community.
Just idea, not mandatory. I enjoy the discussion here a lot :)
Petr
Hi Petr
i have tried every imaginable way but not a.sin(). this is working very nice.
i will read the book step by step at least the introductory parts.
but this tour with your thinbasic_Rust project was very useful and essential for me, and i think the others will find it like so.
Thanks
Hi Petr
what do you think about putting your DLL in Rust to GitHub
of course, but after i complete the Simpson figure DLL, in fact you have provided every thing and it is in fact your DLL. if i have stumbled with it i will tell you.

Primo,
you are too kind - the DLL is so barebones that every DLL will be similar.
As for the sin functions, both of these forms are okay:
fn main() {
let angle_deg: f32 = 45.0; // Equivalent of `dim angle_deg as single = 45`
let angle_rad = angle_deg.to_radians(); // Easy conversion to radians
let sinus_of_angle = angle_rad.sin();
let another_sinus_of_angle = f32::sin(angle_rad);
println!("Sinus of {} degrees is {}", angle_deg, sinus_of_angle);
println!("Sinus of {} degrees is {}", angle_deg, another_sinus_of_angle);
}

Hi Petr
at last i have a compilable version of Rust Dll without errors after a big help from you. but from thinbasic the returned UDT array elements have value = 0 , so there is no graphics but a blank window
regarding the t variable, when using it as t i got :
warning: unused variable: `t`
--> src\user_defined_types.rs:44:13
|
44 | let t = t + 0.01;
| ^ help: consider using `_t` instead
|
= note: #[warn(unused_variables)] on by default
Finished release [optimized] target(s) in 1.31s
even i have dimmed it before in line 36 so i have changed to _t
for who wants to compare look this thread:

here is the rust code (file user_defined_types.rs in your package in GitHub):

Hi Primo,
you were really close! Great job on Rustifiying :)
I think the main issue is related to your handling of t variable.
Instead of this:
let _t: f32 = 0.0;
it should be declared like this:
let mut _t: f32 = 0.0;
Why? Because you want _t to change its value over time. Specifying mut means it is mutable, changeable.
Other minor tweak can be done with:
let _t = _t + 0.01;
You are basically re-declaring (shadowing) the original _t here.
Change it simply to:
_t = _t + 0.01;
This was not possible before, because your _t was not mutable.
Can be further tweaked as:
_t += 0.01;
Other minor tweaks:
no need to define custom pi, Rust has it for you as ::std::f32::consts::PI
no need to have t as _t - I guess Rust adviced this, because he detected it is not used, thanks to the accidental shadowing (and here is from where the zeros came)
the theta function does not need to be pub, pub means the functions is public (visible from code file), neither extern (you don't call it from DLL). #[no_mangle] means "do not change the name in the final DLL", so it is not needed either
Your Rust side then becomes:
fn theta(a: f32) -> f32 {
if a <= 0.0 {
0.0
}
else {
1.0
}
}
#[no_mangle]
pub extern fn UDTVector3DArray(vector_ptr: *mut Vector3D, count: i32) {
let pi: f32 = ::std::f32::consts::PI;
// Converting pointer to so called slice, the _mut allows us to write
let vector = unsafe { ::std::slice::from_raw_parts_mut(vector_ptr, count as usize) };
let mut t: f32 = 0.0;
// Writing new values

you are Petr a Great Professor of Rust Programming Language somewhere !!. and your notes is very detailed and valuable not for me only but for any one trying to learn the language. Thank you very much.
i got a big Simpson figure so i scaled it down by:
TBGL_Scale 0.03, 0.03, 0.03
this is the output of the thinbasic_Rust DLL :
9872
the speed of displaying the graphics is very speedy.
but who support the Rust project financially, certainly there is too much costs to run their servers, thousands of users is connecting at the same time to their servers downloading their code dependence and this is costly.
Edit: i have found it : https://www.rust-lang.org/en-US/friends.html
it is a lot of companies and organizations
look also here: https://www.ibm.com/developerworks/library/os-developers-know-rust/index.html
can't believe i never heard about Rust until Petr mention it occasionally somewhere here, and then i have downloaded it as a one big offline, i was able to run 'hello world' and then i forget it ,after that when John posted the topic Tbo2 ?? i have suggested
to Eros and Petr to develop thinbasic in Rust and then Eros provided the link to thinbasic Rust connection in GitHub
the History works in a bizarre way

Hi Primo,
congratulations on getting Bart to the screen!
As your research suggests, Rust has grown incredibly since 2015, when the first official release was out :) First an hobby project of Mozilla developer, now Rust contributes to the new, fast Firefox core.
Dropbox backend written in Rust. Npm using it...
Rust and ThinBASIC do not compete, they nicely complement each other. ThinBASIC is perfect as day-to-day sidekick for string wrestling at work, and Rust is that strong friend who gives you a hand when in need of performance.
I like that Rust has strong long term vision, frequent updates, they clearly state which parts of design are final and which might change. And the way they worked around the OOP cliche? Neat.
I originally started to re-learn C++, buying excellent book - C++ Primer. Going through the book, I was crying of joy seeing the excellent explanations and great teaching style, and crying of pain seeing how much does the long development of C++ hurting the clarity of design. Rust, on the other side, is very hard to grasp at first (reverses lot of expectations), but once you understand the main principles, it is really smooth to use. Compiler with package manager and easy to understand error messages. Wow.
The place where it really got me is how I could re-implement PowerBASIC/ThinBASIC string in Rust so it is used naturally with the language. Very comfy.
Now it is possible to write simple thinBASIC modules with Rust, like https://github.com/petrSchreiber/thinbasic_rusty shows. That means DLLs, which do not need any DECLAREs.

Hi Petr
The place where it really got me is how I could re-implement PowerBASIC/ThinBASIC string in Rust so it is used naturally with the language. Very comfy
you should go commercial with Powerbasic with the help and arrangement of others and the company itself, if you have provided Rust x64 Dlls for powerbasic :the strings, numerics and maths, graphics, hands, legs, ears, noses, skin...in the form the classic users of PB likes , what remains is the compiler itself in x64, so the big amount of efforts reduced to more than 50%. i saw even in the GitHub a packages which are calling the windows api for Rust. so this is the only horizon i see for the powerbasic airplane to go.
a small prototype may be done as a showcase for the PB experts to evaluate.
Edit:
and why staying with the same compiler core as implemented by BZ in assembly; it is like trying to decipher the pharaoh hieroglyphics scripts, a killer task, it is possible to borrow one of the free x64 compilers and with arrangement of its owner (or using Rust compiler itself for fully Rustified product) just plug in your x64 string and other dlls or say modules, and then you have a new fresh PB x64 compiler which have the taste and flavor of the original PB compiler. this is easier and less costly than trying to decipher the original old code.
Edit2: i have changed my mind, since the task i have suggested is unimaginable big and making a big stress if it is initialized seriously by one man, it needs a group .
but i keep my suggestion even it has the signature of mission impossible.
i will download and try your thinbasic_rusty
big thanks

Hi Primo,
thanks a lot for the encouragement :)
PowerBASIC has a special place in my heart - be it countless hours writing 2D and 3D games for PowerBASIC for DOS, discovering the secrets of OpenGL in my teen-era, saving my butt when Microsoft compiler OpenCL bindings broke when working on my diploma thesis and... of course - having fun developing for thinBASIC for 10+ years in it. All of it thanks to support from Eros and José Roca.
However - I found out I was using ThinBASIC more and more (and yes, it is and will be slower than compiled PB), and returning to PB I found out I miss some cool syntax sugar thinBASIC brought over the years. I use ThinBASIC daily at Avast as well to make my life simpler. It is something like tatoo on my hand, we grow together :)
I also have some internal need to play with GPGPU and high performance compilers, and Rust does it for me very well, along with challenging my brain to think differently once again.
I have some crazy ideas how to boost core ThinBASIC, as well. I can't wait to meet with Eros to discuss it in person with whiteboard to help me organize the thoughts, hehehe :)
Petr
Petr, all the universe is based on crazy ideas , so boosting the speed of thinbasic core to twice or thrice or more will be the most wanted feature.
i have noticed that the available opengl implementations for Rust https://github.com/rust-unofficial/awesome-rust#graphics does not support red book opengl v1.1 , i have tried to find one glTranslate or glRotate in the implementations and can't find, they are all support whats called "modern opengl" which are not tasty at all for all persons over 50 yo.
so i think of another approach, inspired by Petr work about calling powerbasic dll from Rust. the plan is call powerbasic dll from rust and let the dll call the classic opengl v1.1
here is an example, i use purebasic DLL because it has a OpenglGadget which makes the user code smaller, and call it from thinbasic to draw a triangle. i have also tested it with rust and it works. here is a show case of what i mean:
Thinbasic calling code:
Declare Function MyFunction Lib "PBDLL.dll" Alias "MyFunction" ()
function tbMain()
MyFunction()
End Function
Purebasic DLL code:
OpenWindow(0, 50, 50, 640, 480, "OpenGL demo")
SetWindowColor(0, 0)
OpenGLGadget(0, 0, 0, WindowWidth(0) , WindowHeight(0))
ProcedureDLL.l MyFunction()
Repeat
rot.f+1
glViewport_(0, 0, WindowWidth(0), WindowHeight(0))
glMatrixMode_(#GL_PROJECTION)
glLoadIdentity_()
gluPerspective_(30.0, Abs(WindowWidth(0) / WindowHeight(0)), 0.1, 500.0)
glMatrixMode_(#GL_MODELVIEW)
glLoadIdentity_()
glClear_(#GL_COLOR_BUFFER_BIT | #GL_DEPTH_BUFFER_BIT)
glLoadIdentity_()
glTranslatef_(0.0, 0.0, -8.0)
glRotatef_(rot, 0,1.0,0)
glColor3f_(1.0, 1.0, 1.0)
glBegin_(#GL_TRIANGLES) ; Start drawing a triangle
glColor3f_ ( 1.0, 0.0, 0.0) ; Set top point of triangle to Red
glVertex3f_( 0.0, 1.0, 0.0) ; First point of the triangle
glColor3f_ ( 0.0, 1.0, 0.0) ; Set left point of triangle to Green
glVertex3f_(-1.0, -1.0, 0.0) ; Second point of the triangle
glColor3f_ ( 0.0, 0.0, 1.0) ; Set right point of triangle to Blue
glVertex3f_( 1.0, -1.0, 0.0) ; Third point of the triangle
glEnd_() ; Done drawing the triangle
SetGadgetAttribute(0, #PB_OpenGL_FlipBuffers, #True)
Until WindowEvent() = #PB_Event_CloseWindow
EndProcedure
attached the pb dll for convenience (checked with https://www.virustotal.com and found totally clean 0 / 66)

Hi Primo,
I agree that the new raw graphic APIs do ask for a great amount of knowledge from the user. I actually perceive the hardcore trend as positive one, as it allows those, who need maxx power to reach it (very hard 5 years ago), and I consider it responsibility of abstractions to provide the nice-to-use interface.
It is a not a problem to implement own glRotate, glTranslate - they are just manipulation of the matrix:
https://en.wikipedia.org/wiki/Rotation_matrix
https://en.wikipedia.org/wiki/Translation_(geometry)
It is hard to read code full of matrix implementations, the learning curve is not as steep with glRotate / glTranslate like functions.
I recommend to write such a wrappers, I did the same in entity system in TBGL - it does not use any glRotate/glTranslate internally.
Petr
Hi all,
What's your opinion about Nim ? Its also a system programming language. Python like syntax with C like power and speed. And it is coming with GC also. I just tried it. Looks very nice to me.

Hi kcvinu,
I had a look at Nim - do like the Pythonish syntax. The drive of the Rust community seems bigger to me, so I stick to my rusty love :P
Yet - I am glad to learn more about Nim. Could you please open new thread and let us know what you like most?
