Automatically generated JS library wrappers?

ts2nim identified the .d.ts file if the method is `TSMethodSignature` it will add `importcpp` pragma to that function.

Any possibility of a near term Lazarus/C#-like GUI-designer IDE?

This is very interesting topic,,bump.

How to evaluate string in Nim's VM at runtime?

Hi, I'm writing custom ast builder, and was thinking instead of dumping the ast to file, use nim for runtime evaluation For ex. lets say we have echo(1 < 2) # true Run what I want is: echo evalDsl("1 < 2") # should output true Run Is thi

recursive iterators - is there a recommend workaround?

I have to say, @HJarausch, you started this thread looking for a "recommended workaround'. I feel like we gave you a pretty good, if limited, one. Now you are "moving the goalposts" (shifting criteria for 'success') towards having iterators with each & every feature of Python's just to be deemed

Automatically generated JS library wrappers?

I have seen multiple .d.ts to Nim translators, but I don't know if they're capable enough for most libraries. [I found this through google](https://github.com/mcclure/dts2nim) but it hasn't been worked on in 4 years, [here's another one](https://github.com/bung87/ts2nim) but I don't know if it

Urlly - a new library for URL parsing for C/JS backends.

Nim's standard library `uri` module does not parse query strings parameters. While `cgi` module parses the query string, but it does not work in js mode. I need to parse URLs in js mode! This led me to make a module that works everywhere C and JS and parses everything! I was not thrilled about

Is there any nim based 2d collision detection lib?

I was going to say I have a lib, but @hugogranstrom beat me to it! Currently is not a full physics engine, so it will not do collision response, velocity, inertia etc... but it will do collisions between polygons and circles. It will tell you fi they are over

recursive iterators - is there a recommend workaround?

Thanks for your comments. Currently I don't have enough experience in Nim - I am still learning. And since I am still convinced that iterators should upgrade from second class citizens to first class citizens in Nimland, tricky macros are not a solution. For a pull request concerning the compil

recursive iterators - is there a recommend workaround?

So, I get this is example code, but your `fibonacci` has no parameters. That makes it not a very good match for a closure iterator factory proc in the first place. Maybe if it did you could do your composition "inside" `fibonacci` instead. E.g.: proc fibonacci(its = 0): iterator()

How can I do 'fetch' or 'XMLrequest' thing in JS?

Thanks. I gave it a little try. For simple 'GET' fetch, it works and JS code is compact, perfectly. If I do some 'POST', the JS code starts to get fat. I don't think its extra large, but a bit messy. Any way it works. I can choose going along with this or just using karax. Thank you so much. I
