CSharpRepl VS rcf

The C# REPL I'm talking about is simply called... C# REPL. It's an open-source project created by Will Fuqua, and as of today, it has over 2k GitHub stars. It is distributed as a .NET tool and is cross-platform. In this blog post, I'm going to show you how to install it on Windows Terminal, but you can install it on any terminal emulator you prefer.

> The repl driven workflow is amazing and the lisp images are rock solid and highly performant.

do people not realize that basically everything vm/interpreted language has a repl these days?

not to mention ruby, python, php, lua

hell even c++ has a janky repl https://github.com/root-project/cling

Let me introduce you to my lord and savior https://github.com/waf/CSharpRepl

Not the answer you’re looking for, but I haven’t been able to run LinqPad since I moved to Mac OS. Polyglot notebooks plug-in for VS Code comes very close to LinqPad, or if you don’t mind Terminal/CommandLine csharprepl is amazing.

For REPLs, there are options like (my own) https://github.com/waf/CSharpRepl which stand on top of the Roslyn compiler infrastructure, which is quite extensive and can easily evaluate standalone functions and statements.

It's still nowhere close to the REPLs of lisp and smalltalk, but it's a step in a more flexible direction.

After doing some interactive development, I will occasionally reuse some of this example code and make it into actual, formalised tests in the test namespaces. Some people have started using the comment form for actual tests too, e.g. hyperfiddle/rcf or matthewdowney/rich-comment-tests.

Test lib is https://github.com/hyperfiddle/rcf, which had a release last week – the release is a noop from userland but has a bunch of infrastructure we need (RCF now implements the Clojure/Script analyzer to extend Clojure syntax so that (do x := y) is an async test assertion at any depth in the form.)

Not to make you feel too bad, but based on your sentence you may appreciate a recent addition to my personal REPL toolkit in Clojure which I very much enjoy.

You may remember the rich comment forms in Clojure development as a communication tool to your future self and others. Now someone made them testable https://github.com/hyperfiddle/rcf#readme

I use shadow-cljs server for both node and browser, the REPL is instant. There is some configuring though, you can probably get help in slack. (Shameless plug – JS has lots of async, to tame that at the REPL try https://github.com/hyperfiddle/rcf)

If you have concerns about the correctness of get-book-tags in isolation I would suggest https://github.com/hyperfiddle/rcf,

Based on https://github.com/hyperfiddle/rcf, a REPL-first test macro for Clojure/Script which turns your Rich Comment Forms into tests (in the same file as your functions). It's good, try it!
