Hi elmonkey,

Have a look at:

http://rosettacode.org/wiki/Category:Nim here you can see, how common problems are solved with Nim.

Then also: http://ssalewski.de/nimprogramming.html A book about Nim.

Make sure to also read the manual and tutorials from miran's link.

Another good advice is to just read others code, so you'll get familiar with the style Nim is usually written.

I have video series for Nim Beginners if you are interested: Nim for Beginners: https://www.youtube.com/playlist?list=PLvwc2YT9MFOlPPexrsY-t7BNTdg2Vsx06

Hi and welcome!

Feel free to join the discord/irc and ask questions if you get stuck!

If you're already familiar with programming in other languages and just want to learn Nim, the Nim Tutorial is quite good! https://nim-lang.org/docs/tut1.html

Also this: https://nim-by-example.github.io/ This is what i used when i joined Nim. Also Nim in Action book(on manning website, there should be a promo code in a blog post somewhere, probably a blog post by dom96 the author), less of a beginner book, but it has some very good explanations of certain things and some good examples.

Depends on your level of course, I used https://learnxinyminutes.com/docs/nim/ to get an idea of what Nim has to offer and how it "feels" to write. After that I tried implementing things with the help from the manual and some Nim by example (which @Kiloneie just shared).

Great non obvious recommendations.

Get yourself a book "Python Crash Course 2nd Edition", read it with Nim tutorial part 1, And Nim for Python programmers from Nim Wiki on github. Translate yourself code from Python and write it as Nim, there are some differences but it's really easy to spot them. And of course do the exercises from the book. They are the most valuable.

And the last thing - read runnable examples from modules in Nim stdlib. They have nim snippets that are ready to run and use.

please don't do this...

@SebastianM I think it's pretty amazing that it works for you, no need to regret suggesting this solution.

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

SebastianM (orginal) [2021-11-03T20:50:09+01:00] view original

Nim already has something great for beginners: http://ssalewski.de/nimprogramming.html

But I took Python book for plenty of easy exercises.

The exercises from Miran book was too hard for me and tutorial goes too fast.

But of course these sources are great and I'm sure that would stay usefull for future Nim newcomers.

The exercises from Miran book was too hard for me and it goes too fast.

Can you get in more detail, please?

What would make the exercises easier? What would "slowing down" be: more examples, more explanations, both, something else?

SebastianM (orginal) [2021-11-04T10:39:25+01:00] view original

Hey,

As for exercises I feel they focus heavily on math with numbers, Collatz problem.Maybe there could be more exercises with only a small change and some that tell a story e.g favorite pizza (with a seq of ingredients), 99 bottles of beer, animals, etc.: I feel also that text is very short and only scratches the surface of each topics. I understand that it may be intentional, but it ends so quickly ;-)

I find the code listings with explanations with numbers very useful, and personally think that these should be even more. If you would like to expand this text in the future a good idea in my opinion would be to add chapter about basics of TDD, and how beginners could write tests to test their knowledge - either with asserts or unittest library(I did't use testament - maybe it would be better).

I have been kinda going the same thing, find some python code and try to write in python. The only thing though python doesn't use types so you can't always looks at python code to make it work in nim. I also have the "NIm in Action" book and use the Nim manually a lot.

SebastianM (orginal) [2021-11-05T17:44:01+01:00] view original

Yes, That's true in Python - that's why in Nim there is some effort to make things work. E.g: for python dict you use nim json module. But the documentation is great enough that some deeper digging can bring the solution. And it's really worth it.

miran (orginal) [2021-11-05T18:48:52+01:00] view original

E.g: for python dict you use nim json module.

Python's dicts can/should be replaced with Nim tables. I think I have never used json module for that.

SebastianM (orginal) [2021-11-05T20:12:21+01:00] view original

Yes, I was referring to multiple types as values.

Probably not good idea to use it like that, but curiosity won :)
