Top 23 Nim HacktoberFest Projects

  • Nim

    Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

    A sinatra-like web framework for Nim.

  • Project mention: Nim v2.0 Released | | 2023-08-01
  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • Project mention: Nim v2.0 Released | | 2023-08-01

    Congratulations to everyone involved and the entire Nim community!

    Nim has been my language of choice for the past decade and I'm really happy with the new features in Nim 2.0. Some of them are real gamechangers for my projects. For example, default values for objects theoretically allow me to make Norm[1] work with object types along with object instances. And the new overloadable enums is something Karkas [2] wouldn't be possible at all (it's still WIP though).



  • futhark

    Automatic wrapping of C headers in Nim (by PMunch)

  • Project mention: C23: A Slightly Better C | | 2024-01-21

    You don't want nimterop, you want futhark (

    The C FFI Nim library lineage goes c2nim --> nimterop --> something i forgot --> futhark.

  • nimpylib

    Some python standard library functions ported to Nim

  • ggplotnim

    A port of ggplot2 for Nim

  • Project mention: Chinchilla Scaling: A Replication Attempt | | 2024-04-19

    That is certainly true (and why added a general "embed plot data as bitmap into SVG/PDF" option to that works not only for raster heatmaps). But realistically such plots are often not ideal anyway (too many data points in a plot is often a sign that a different type of plot would be better; typically one that aggregates in some way) and it's just another argument to make the data for plots available as well.

  • jupyternim

    A Jupyter kernel for nim

  • Project mention: Arraymancer – Deep Learning Nim Library | | 2024-03-28

    I just had a look, and there does seem to be a Jupyter kernel at

  • fusion

    Fusion is for now an idea about how to grow Nim's ecosystem without the pain points of more traditional approaches. (by nim-lang)

  • Datamancer

    A dataframe library with a dplyr like API

  • ratel

  • Project mention: Nim v2.0 Released | | 2023-08-01

    Ones that have not been mentioned so far:

    nlvm is an unofficial LLVM backend:

    npeg lets you write PEGs inline in almost normal PEG notation:

    futhark provides for much more automatic C interop:

    nimpy allows calling Python code from Nim and vice versa:

    questionable provides a lot of syntax sugar surrounding Option/Result types:

    ratel is a framework for embedded programming:

    cps allows arbitrary procedure rewriting to continuation passing style:

    chronos is an alternative async/await backend:

    zero-functional fixes some inefficiencies when chaining list operations:

    owlkettle is a declarative macro-oriented library for GTK:

  • Unchained

    A fully type safe, compile time only units library. (by SciNim)

  • Project mention: GNU Units | | 2023-08-03

    Anything with a finite (200 is small even) number of units misses the algebraic structure of the problem mentioned in wherein multiplying|dividing two things gives you a (potentially) new unit which implies an open ended "space" of units.

    To be concrete (hah!), in C++ a template meta-type with 12 signed integer parameters (6 numerators & 6 denominators for rational exponents of SI base units) might be one way to model it.

    Unlike C++ template stuff, Nim macros (like Lisp macros) makes metaprogramming more like procedural programming - just against abstract syntax trees. I think that helps to shield some of this type complexity from users, but the documentation README does better job than I can in an HN comment.

    Of course, for unit system conversion, the number of dimensions (6 in SI, 3 in CGS/Gaussian) changes. So, for full generality you need compile-time (if you want static type integration/CT errors) linear algebra over a rational field (at least & conventionally) to project|inverse project. That might be theoretically possible in C++. I would think it very un-fun and unlikely to ever have been done. There's probably a Mathematica package, though.
