A Surfeit of Sandboxes

You may be familiar with JSFiddle and CodePen, but there are similar tools for a variety of languages, some more practical than others.

Need more flexibility than a single-language environment can handle? FiddleSalad lets you combine different markup, style, and programming languages.

Special mention: Compiler Explorer is an interactive tool showing how C/C++ programs are compiled to assembly code.

If you just want to get straight to a console, repl.it (previously) has you covered.

This doesn't seem to include PHP Tester.

...or CFLive, for Cold Fusion and Lucee (a fork of Railo). Nevertheless, a neat collection!

Also for PHP - PHP Sandbox.

I see a lot of Angular developers using Plunker.

Will definitely keep the RegEx ones in mind, because I do not want to have two problems!

There's also Rubular, which lets you play with regular expressions as they are implemented in Ruby.

It's kind of weird that they don't include JS Bin or CodePen on their list.

The site does say "Did I miss a fiddle? Let me know via email or Twitter: [e-mail] | @jpalomaki"

If you want to dive into the languages used for chip design (at least Verilog/SystemVerilog etc.), you can use:

In the "other" Hello World demo I removed a single + and got the answer: H[bbe WehbZ!

Illuminating. NOT

If I understand best development practices in bf are essentially throw random bit in a bucket and keep stirring.

I'm sortof torn by the profusion of repl demos on the web, certainly fun to see how a one liner works in a new language, and I certainly use them during development for getting a bit of syntax straight but writing a small file and running it for any but trivial things make more sense. I guess writing in one window and pasting into the repl browser too may make sense. Hmm. Is there an online emacs?-)

That is pretty much the case for Malbolge, as demonstrated by MeFi's own andrew cooke.

Sammyo, I found this: Ymacs.

But it doesn't seem to have a place to put your emacs.d, so my Spacemacs config remains on my netbook.

There are a couple of TypeScript playgrounds if you don't get enough abuse from compilers at work.

Jupyter Notebook.

The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, machine learning and much more.

PostScript sandbox.

I really want F77, Forth and Perl, though.

The nice thing about Codepen and the like is that you can prototype a thing quickly as a proof-of-concept. It's also great for learning in classes, as you can code along silently as the instructor codes aloud, then share your Codepen ID with the class. (Worked like a charm in a CSS animation class I took a couple of summers ago.)

OK, here are two more that must be added:
Apple ][ BASIC in JavaScript
LOGO in JavaScript

10 PRINT "AWESOME"
20 GOTO 10

] RUN

Skulpt is pretty cool, mostly because of the turtle graphics.

Or you could go real old-school and fire up Turbo C (but where's my Pascal and Prolog??)

Plans this weekend? Where we're going, we don't need plans this weekend.
