core.async VS Gradle

Hey, how you doing? This article was written right after I had to painstakingly read the clojure.core.async source code in order to finish a task. So, I hope I save you from the same fate as I had 😄.

It was created by Rich Hickey: https://github.com/clojure/core.async/commit/47b1d24c0291050a1188dbeee2fc9227f694eb3c don't think he's disavowed it lol.

Some time ago we developed some helpers using the capturing notifications strategy to test asynchronous ClojureScript code that was using core.async channels. Have a look at, for instance, the expect-async-message assertion helper in which we use core.async/alts! and core.async/timeout to implement this behaviour. The core.async/alts! function selects the first channel that responds. If that channel is the one the test code was observing we assert that the received message is what we expected. If the channel that responds first is the one generated by core.async/timeout we fail the test. We mentioned these async-test-tools in previous post: Testing Om components with cljs-react-test.

Hi there I'm using Clojure almost a year. I've played with both Manifold and core.async a bit but I'm not %100 sure when to use core.async over Manifold or vice versa.

If you're not familiar with lisps in general, it might be hard to grok the differences between lisp-macros (as used in Clojure) and "normal" macros you see in other languages.

But, if you are familiar already, and just wanna see examples of neat macros that makes the API nicer than what a function could provide, here are a few:

> and with a very poor tooling (lack of IDE's)

Lisps have fantastic support in Emacs and VSCode and are in general simple enough languages that often the heavyweight of an IDE is not needed. But if you want IDEs there are:

If you don't want to block the current thread, you can do the looking/waiting on another thread via thread or in a go using alts! .

Because executing CodeNarc from the command-line is not so simple, I find it easier to use Gradle and its dedicated plugin to execute CodeNarc:

A ("shared") build service is kind of like a singleton, in that when you register one in any project, it's available in all projects as a single instance. (This unfortunately turns out not to be true, in some cases, when using composite builds, but can be worked around.) An actual singleton (global static instance) doesn't work at all, for the record—try it if you want to lose some sanity. Anyway, use a build service whenever you need global mutable state in your build.

When using build tools like Maven or Gradle, you can configure environment variables in the build scripts or configuration files.

For large projects, purpose-made build tools such as Gradle and Maven are preferred for managing the directory structure since they introduce additional semantics for managing test code and other programming languages (among lots of other things). Most IDEs can integrate with these build tools easily. If you're just starting out though, I wouldn't worry too much about these, you can visit them later.

Project Build and Management: Apache Maven 3 (3.9.5), Gradle 8 (8.3)

No wonder this had been raised previously, https://github.com/gradle/gradle/issues/15383

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

The details regarding the code compiling would vary from one project to another. For that project, it seems that it uses Gradle (a helper tool) for compiling. Check Gradle's documentation for more information.
