idea : reuse libraries from other languages

`cpython` looks nice. I just installed it, but I couldn't find any examples in github page.

GUI program is not working when using app:console in version 2.0

Update: It is working, but only with `--mm:boehm` and `--mm:arc`. Not with orc & arc. And another strange thing, It is not running when we double click the exe file in explorer. But it will run if open a cmd window in that directory and run the program from cmd.

Oh sorry, it was just a typo. I used `--app` in my cmd.

GUI program is not working when using app:console in version 2.0

Hi all, I just faced a strange problem. I was used version 1.6. Now I decided to update my Nim version to 2.0. But after updating, my GUI program is not running. It is compiled successfully, but it is not running. The compiler command I was used at that time was `nim c -r app:console filename.ni

Nimforms - A simple GUI library for Windows

> doesn't work for me Any error messages ? Or any images ? It will be easy to understand what the problem is. What you said about GUI libraries is quite amateurish. I had similar thoughts in the beginning. I sent a mail to the creator of Python in 2010. Asking if a language without a visual GU

Nimforms - A simple GUI library for Windows

@mx1990, manifest file added to the repo. Just download it and place on your exe location. But remember one thing. The name of the manifest fie and exe file must match. For example, if your exe file's name is `app.exe`, then your manifest file must be `app.exe.manifest`. Otherwise it won't work.

Nimforms - A simple GUI library for Windows

Now i found the issue. You need the manifest file in your exe's location. I will upload the manifest file in my repo. You just need to place it near your exe file.

Nimforms - A simple GUI library for Windows

@treeform, createHandle is the function where the actual call to CreateWindowEx is happening. Users can change the default values of any control right before it is created. But yeah, if you think calling createHandle too much time is annoying, I can add a boolean parameter to the constructor. If

Is it possible to play with xidoc without Nimble ?

Macros: why and/or when to use them?

Actually, my project was a GUI library based on win32 API. I have stopped it when I knew the limitations in modularity. Then after a few months, I've started it again with making benefit from "include" statement. In this method, All I need is to plan my code as a single file and properly order m

Macros: why and/or when to use them?

I know that the people behind Nim doesn't like when I said, "Hey there is a problem in modularity". So I stated it in good words. If I say, it's my problem, they will say, "Okay then learn how to solve it." But I know that I don't have any problem in modularity in other languages. I know they ar

Macros: why and/or when to use them?

This is the rule which works for me because I don't know anything about macro and template. If a proc works, use a proc. Elif, make a problem-specific solution. Else drop the project and start with another language.

Preview of coming attractions?

// I don't personally mind forward declarations and the lack of cyclic imports but we'll get a solution for this too. // Eagerly waiting for this. I request your attention to D's "package" scope. It will be a good idea. If we declare a type with package level scope, the entire project can see th

I think he is implicitly stating that Nim needs a nice introductory book like Python Crash Course 2nd Edition.

wNim - Nim's Windows GUI Framework

It's quite easy to work with win32 API in Nim. You can use CreateWindowEx function for creating a window. But you need to use few other win api functions for that. Like GetModuleHandle, RegisterWindowEx, LoadIcon, LoadCursor, CreateSolidBrush, ShowWindow, UpdateWindow, GetMessage, TranslateMessa

Mac GUI

Hi, Thank you for your expressions of sympathy. Well, Coca is different from Win32 API. Your current implementation seems very good. It took lot of boilerplate code from a Nim user. Thanks for your effort.

Mac GUI

@AIR, Assume that I have a button. I want to add a click event handler and a mouse enter event handler for the same button. In my Windows GUI lib (Not completed though), every control has different events. And you can set like this. var win = newWindow() win.create() # Will

How to rewrite nim programming langauge to be pythonic as possible?

Wow ! Sounds good. I wish I can write a class in pure python style. I know that Nim can do that with the help of some macros but I don't prefer macros. It is good for a language to have the ability to do the most basic things without any macros. What will be the name ? Nimthon ? ha ha :)

Mac GUI

I apologize for not writing clearly what I meant. I meant how to connect a MouseEnter event handler or a MouseLeave event handler along with a Click event. To be frank, how to connect two different event handlers to a single control (widget)

Mac GUI

Wonderful !! Now, one can easily create a mac gui with this library. The code is straight forward and neat. I wish Windows had a gui lib like this too. I know there are plenty of gui libs for Windows. But none of them are expressive like this. This is a a simple aproach. I have a question. How d

Performance comparison of various compilers

Try D with DMD compiler. It is the fastest I think. I have same project in Nim & D. When I hit run button, D project compiles and run first.

What is happening under the hood of "cast" function ?

Oh, I missed it. It's very clear. No doubts. When asking this question, converting a tuple with 3 int elements to COLORREF was in my mind. Have read about the "Mantissa" in a YT video few month ago, but I felt that's a tough subject.

What is happening under the hood of "cast" function ?

Sorry for introducing a D feature in Nim forum. I am always a fan of simple programming. If you can do the magic in one line of code, i will call it simplicity. There are lot of simple things in Nim. Great language with ease of use. But unfortunately, i am not a fan of macros in Nim. May be beca
