Top 23 Language Open-Source Projects

  • go

    The Go programming language

    Project mention: Fixing for Loops in Go 1.22 | | 2023-09-19

    I agree that there are no objective measure. I guess it's just different expectations.

    I would not say it's obvious what the machine is doing in the Go example though. For example it wasn't clear to me that append() mostly doesn't copy the full vector, but does a copy of the slice pointer. I had to look it up from a blog post, because the source for append() is gnarly

  • TypeScript

    TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

    Project mention: We use TypeScript not based on preference, but because we want to make money | | 2023-09-15

    Zod is great. It has some weaknesses - you can't just reuse types from external libraries; it can be verbose.

    There are some libraries that provide a cleaner experience (e.g. typescript-is/typia). But they rely either on code generation or extending the TypeScript compiler while Zod just makes do with some clever typing.

    TypeScript itself will never integrate something like this as it goes against their design goals[1].

    Project mention: Interesting const interior mutability issue | /r/learnrust | 2023-09-21

    I'm surprised there isn't a warning about this already, though there is an open issue about it

  • zig

    General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

    Project mention: Bun vs Node.js: Everything you need to know | | 2023-09-21

    Both Node.js and Bun are runtimes. Node.js is primarily written in C++ where as Bun is written with a low-level general purpose programming language called Zig. But that is just the tip of the ice berg. Let’s take a closer look at other differences when treating Bun as a runtime alone.

  • solidity

    Solidity, the Smart Contract Programming Language

    Project mention: a solidity compiler observation that does not make any sense, anyone knows why? | /r/solidity | 2023-07-25

    Inconsistent gas usage for conversion of calldata to memory in external call and internal call. · Issue #14444 · ethereum/solidity (

  • ruby

    The Ruby Programming Language

    Project mention: Undocumented Features of GitHub | | 2023-09-11

    Hold option and click on the “collapse file” button in the Files view of a commit or pull request, and it will collapse all the files.

    Select text in a comment, issue, or pull request description and press r—the selected text (including markdown formatting) will get pre-populated as a markdown block quote reply in the next comment box.

    Add .patch or .diff to any pull request URL if you want to see a plain-text diff of the pull request (e.g. maybe you want to quickly `curl ... | git apply -` an unmerged pull request into a local copy of the repo without trying to add and fetch the git remote that the pull request is from).

    There are lots of keyboard shortcuts. For example, / to jump to the file finder.

    Not so much a secret but more like a hiding in plain sight: when looking at a commit GitHub will show you the earliest and latest tag (i.e. release) that includes the commit. For example, this commit[1] first appeared in v3_2_0_preview3.


  • crystal

    The Crystal Programming Language

    Project mention: RFC 3339 vs. ISO 8601 | | 2023-08-31

    An often ignored part of the standards are how to represent durations (time spans).

    See (section: Representation of time-interval by duration only, pg. 21)

    Would like to see more json parsers in static languages allow me to define a field as a time span and can serialize into the valid format.

    For an example, see this proposal in Crystal:

        Example:  A duration of 15 days, 5 hours, and 20 seconds would be:

  • less.js

    Project mention: An Overview of 25+ UI Component Libraries in 2023 | | 2023-09-10

    Extensions of CSS: for example, Sass, Less, Tailwind, CSS Modules, to make stuff look a certain way on your own.

  • RustPython

    A Python Interpreter written in Rust

    Project mention: Our Plan for Python 3.13 | | 2023-06-15

    I'm actually rooting for RustPython to reach a level of maturity that we'd just be able to ship apis and stuff with it....

  • 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).

    Project mention: Removing Garbage Collection from the Rust Language (2013) | | 2023-09-11

    20 milliseconds? On my 7 year old Linux box, this little Nim program runs to completion in 275 microseconds when fully statically linked with musl libc on Linux. That's with a stripped environment (with `env -i`). It takes more like 318 microseconds with my usual 54 environment variables. The program only does about 17 system calls, though.

    Additionally, makes decent CLI tools a real breeze. If you like some of Go's qualities but the language seems too limited, you might like Nim: I generally find getting good performance much less of a challenge with Nim, but Nim is undeniably less well known with a smaller ecosystem and less corporate backing.

  • enso

    Hybrid visual and textual functional programming.

    Project mention: Show HN: Ezno, a TypeScript checker written in Rust, is now open source | | 2023-06-07

    I think Enso is already taken by a YC company [0]. Could get confusing.
