Re: Idea: Nim Online Conference
NimConf 2020 was streamed yesterday, and IMO it was a great success! It was the first time for us doing such a thing, and it went quite smoothly. There are some details we would like to improve for NimConf 2021, for which we are hoping it will be even better — if you have a feedback about NimConf 2020, we would like to hear it! We would like to thank all of our presenters for coming up with the interesting topics, recording the videos, and for answering all the questions that came up during the live chat with the audience. Also thanks to all who participated as live audience! We hope you had fun watching the talks and interacting with the authors, and learned something new about Nim, its libraries and cool projects. * * * If you have missed any of the talks, the whole conference (15 talks!) is available for later watching in our [NimConf 2020 playlist](https://www.youtube.com/playlist?list=PLxLdEZg8DRwTIEzUpfaIcBqhsj09mLWHx).

At the time of writing this, we have 114 open PRs (and that's after two weeks of constant merging as fast as possible! The number was much higher last month.), and it should be obvious to anybody following Nim's github repo that we have very hard time reviewing and merging them in reasonable time. One person pinging and/or PTAL-ing (which already happens), just gives an impression "look at my stuff, my stuff is more important than all the other stuff by all the other contributors". NO! @timothee If you really want to help us with faster merging of PRs, take a look at those 40 out of 114 (35%!) open PRs which are authored by you. Are all of them really important (for larger Nim audience, not just for your workflow)? How can we review PRs in time if you're constantly flooding us with new stuff? Long story short: new flags or constant pings don't help with faster reviews. Less "privatization" of Nim repo will.

[link](https://nim-lang.org/docs/sugar.html#\[\].m%2CListComprehension%2Cuntyped%2Cuntyped) But my advice would be: don't use list comprehensions in Nim — think about how would you have written your python code without them and then try to translate _that_ version, you'll have much better time.

Re: Nested list comprehension
There are few problems with your Nim version, e.g. returning `string` instead of `seq[string]` (cause this is what the Python version does - it returns a list). Here is a correct Nim version: proc cross(xs, ys: string): seq[string] = ## Cross product of elements in A and elements in B. for x in xs: for y in ys: result.add x Run

Re: Why is `1 +(2 + 3)` a syntax error?
`1 +(2 + 3)` is translated to `1 +5`, and at that point, `+` is an unary operator (e.g. `+5` is a positive five, like `-5` is a negative five). You can check this if you do `1 - +(2 + 3)`, which will give you `-4` as a result.

Advent of Nim 2019 megathread
This Sunday, December 1st, will mark the start of the fifth edition of [Advent of Code](https://adventofcode.com/). Advent of Code is, to quote its author, _“a series of small programming puzzles for a variety of skill sets and skill levels in any programming language you like”_. The rules of AoC are quite simple. Starting from December 1st until Christmas, every day at 5 a.m. UTC a new task is released. The tasks consist of two parts, where second part is revealed after you solve the first part, and it is a continuation and/or variation of the first part. You don’t submit your code, just the result of your calculation. The participation in AoC is free (although, if you like it, consider [donating](https://adventofcode.com/2018/support)), all you need to do is log in with your Github, Google, Twitter, or Reddit account. If you have never participated in AoC before or you want to prepare yourself for the start of the competition by solving some tasks, take a look at [the previous events](https://adventofcode.com/2019/events). # Nim leaderboard We are organizing the official Nim [private leaderboard](https://adventofcode.com/2018/leaderboard/private), where you can compete against other Nim users. To join the Nim leaderboard, all you have to do is use `40415-c732e66e` code in the previous link. If you are one of 120 (!) people who have joined this leaderboard last year, there's no need to do it again — you're already in. # Misc You can use this thread to post links to your AoC repositories, share your solutions, ask for help, discuss the tasks, etc. but have in mind these things: 1\. **SPOILERS** : Try to keep this thread as spoiler-free as possible: [r/adventofcode subreddit](https://old.reddit.com/r/adventofcode/) will have megathreads for each day and you can post there as soon as the global leaderboard is populated (and that is veeery quickly) — we would like to encourage you to share your Nim solutions there and showcase the beauty of Nim. 2\. **ASKING FOR HELP** : Feel free to ask for help either here or on Nim IRC/Gitter/Discord channel if you have some Nim-related problem, but have in mind that your snippets might contain spoilers for other who haven't solved the task yet — not everybody will be able to solve the tasks at 5 a.m. UTC. Consider waiting at least couple of hours before asking for help (in that time, try it some more to see if you can solve it by yourself :)). 3\. **HAVE FUN** : This is mandatory! # Our AoC 2019 repositories (this will be populated and continuously updated as people share links to their repos)

Re: A super newbie git-related question
This is basically what I do too. You need to do (only once): `git remote add upstream https://github.com/nim-lang/Nim.git` And then, when I want to update my local `devel` branch (e.g. before creating a branch with some fix), I do: `git pull upstream devel`. You still _push_ your changes to _your_ repo (`git push origin `), and then you can create a pull request. * * * Btw, it is not crucial that your branch must be ahead of `Nim/devel` (upstream) — this stuff matters only if you change some file that has also been changed there in the mean time.
Re: Get first element in Table

It happens every year in October, and it is open for everybody to participate. Long story short: after you register at [their site](https://hacktoberfest.digitalocean.com/) (you can login via Github), you need to **make 4 pull requests** (they don't have to be merged) in October to any open source repository on Github and you will receive a Hacktoberfest T-shirt. Nim would like to encourage you to participate in Hacktoberfest by contributing to [our repo](https://github.com/nim-lang/nim). You can help in various ways: * bug fixing * writing/improving a library * * * 1\. Bug fixing We have around 1300 open issues, which might be overwhelming to start, so here are some suggestions: * issues marked with [Hacktoberfest tag](https://github.com/nim-lang/Nim/issues?q=is%3Aopen+is%3Aissue+label%3AHacktoberfest) should be easy to start * if you don't feel like writing code, take a look at [Documentation tag](https://github.com/nim-lang/nim/issues?q=is%3Aopen+is%3Aissue+label%3ADocumentation) * if you want something more challenging, see [Stdlib tag](https://github.com/nim-lang/nim/issues?q=is%3Aopen+is%3Aissue+label%3AStdlib) or [High Priority tag](https://github.com/nim-lang/nim/issues?q=is%3Aopen+is%3Aissue+label%3A"High+Priority;) * * * 2\. Writing/improving a library There is a [list of needed libraries](https://github.com/nim-lang/needed-libraries/issues): can you help us shorten it? Once you have written a library, you should send a PR to [nimble package repo](https://github.com/nim-lang/nimble) to include your package in the official list of packages! If writing a library seems like a too demanding task, you can help improve [one of the existing Nim packages](https://nimble.directory/) by adding a feature, fixing a bug, or writing more informative documentation. * * * Happy hacking, The Nim Team
Re: Nim for Beginners Video Series
Suggestion: Don't have an empty VSCode at the beginning of each video: show a text file with "table of contents" of what you will be talking about in the video
Re: Proposal to start a Nim-Scientific Community
> What do you think is the most lacking in Nim at the moment for Scientific > related stuff? The first thing (it doesn't mean it is the most important) that came to my mind: one plotting library to rule them all. Something all-around like matplotlib, but with sane API :) For other stuff: I agree with @mratsim's list above.
Re: Front page example
There is now a different iterator example on the website. Hopefully it won't confuse people anymore.
Re: Front page example
Every number in `[10, 20, 30, 40, 50, 60]` is even. That's on purpose. This iterator returns elements at odd _positions_ , i.e. index 1, 3, 5.
Re: Nim source size
> For anyone who want to get in with Nim quickly - use Manjaro Btw, Nim v1.0 has already hit Manjaro Testing branch (only half a day after the release!), and it will be part of the next Stable update. (Bleeding edge Arch still has Nim v0.18, lol)
Re: Nim beginners tutorial
To celebrate the release of Nim v1.0, the tutorial has been updated. Several typos and errors have been fixed, but the most noticeable improvement is in the [PDF version](https://github.com/narimiran/nim-basics/raw/master/nim-basics.pdf) of the tutorial, which is now much nicer to read, and not just an afterthought like previously. If you prefer the web version, it is still at [https://narimiran.github.io/nim-basics](https://narimiran.github.io/nim-basics)/
Re: Set Literal Problems
How about something like this:
type
MyRange = range[0'u8 .. 15'u8]
var s = {12.MyRange}
Run
Re: 1.0.0 is here
> Here is Julia's: > [https://discourse.julialang.org/t/version-1-0-released-of-nim-programming-language/29099/16](https://discourse.julialang.org/t/version-1-0-released-of-nim-programming-language/29099/16) And here we go once again, people who didn't even bother to see how style-insensitivity works in Nim: > Case-insensitivity sounds like a terrible feature, and would break much of my > code. `N` and `n`, `A` and `a`, `i` and `I`. I don't have an account there, so if somebody wishes to reply there, tell @DNF that all these are distinct, as the first character is case sensitive.
Re: Compiling?
> Is there a way to get the .c file before the compilation to binary? `~/.cache/nim`
Re: WinCon vs 1.0.0
> So, what should we do now ? You should definitely tell us about it for the fourth time in a single day.
Re: Great tutorials needed
> is the "miran" in "narimiran" the same as @miran ? if so, nice work, thanks ! It is, thanks :)
Re: Great tutorials needed
We have these: [https://nim-lang.org/learn.html](https://nim-lang.org/learn.html) Whether those are "nice and clear step by step tutorials with great explanation" it is up to the reader to decide.
Re: How to use extract string with contains a certain pattern?
> xmltree could handle it, so ... bug report please. It is a known issue: [https://github.com/nim-lang/Nim/issues/1034](https://github.com/nim-lang/Nim/issues/1034) and [https://github.com/nim-lang/Nim/issues/11713](https://github.com/nim-lang/Nim/issues/11713)
Re: Exe file is closes very quickly
> procedure to wait for the user answer to close the window You can use `readLine` at the end of your program. See some examples in [tut1](https://nim-lang.github.io/Nim/tut1.html#the-first-program) and [Nim Basics](https://narimiran.github.io/nim-basics/#_reading_user_input).
Re: Came across a video talking about NIM
> the book expects you to have some other language knowledge first [Nim basics tutorial](https://narimiran.github.io/nim-basics/) doesn't expect you to have some prior knowledge, and shows you the basic concepts in Nim.
