| Cool see this here! But let me provide some context: This is a
| program PG wrote with his kid. He asked me to build into Repl.it
| a classic Basic implementation and make it really easy to do
| graphics programming. So I wrote an interpreter and called it pg-
| basic
|
| Try it here: https://repl.it/l/basic
|
| Docs: https://docs.repl.it/misc/basic

| However, we realized that we can do a much better job on syntax
| and other features. So in collaboration with PG, we're evolving
| the language to make it more expressive and cleaner without
| losing the magic that makes Basic a great introductory
| programming language.

| Thanks for making this, I'll try it out.

| I've been trying to do Pyxel (via repl.it) with my kids. They
| really like coding that draws things, and I really appreciate
| how easy it is to get started. Downside is that some of the
| syntax is a bit confusing. Kids have a hard time with
| whitespace for indent, and the Pyxel draw loop is not really
| intuitive for them. I'll try out this Basic interpreter to see
| if it's a bit better for them.

| Yes try Basic. But even if you want to use Python, I would
| started with our Python Turtle environment which would be a
| lot less confusing than Pyxel: http://repl.it/l/python_turtle

| Thats awesome! Have you ever written a blog post or anything
| about the how repl.it works? Its not typically a JS
| reimplementation right? I always assumed a container/nsjail.
| amasad wrote:
| Yes so regardless of what language or where the language
| runs, we give you a container, inside that container we drop
| in a server that's responsible for most of the functionality
| including editing, collaboration, hosting, etc. A little
| about that here: https://blog.repl.it/collab
|
| The IDE is built on top of a window-tiling manager
| abstraction we built in React.js: https://blog.repl.it/ide
|
| Now, as for languages, most of them do run inside the
| container, which is built from our base image polygott
| (https://github.com/replit/polygott). However, a select-few
| are better suited to run on the client. We have a client-side
| jail called: replbox (https://github.com/replit/replbox).
| Basic, for example, runs on replbox because I wanted to
| graphics to be instant. For something like PyGame or LOVE
| frameworks we had to go with VNC streaming but that's not
| ideal for obvious network reasons.
|
| There is a lot more to it -- it sometimes feels like building
| an entire city -- and you can find some more posts on our
| blog: https://blog.repl.it/ (which incidentally is hosted on
| Repl.it).

| programming.
|
| repl.it is a nice substitute though. Maybe I'll just pull out an
| old computer and force it to boot into repl.it...

| Fun idea! Two years ago on HN I said something similar: "We

| This is awesome and cool. Related (from 20 days ago):

| I just made line numbers optional and it kinda starts looking
| like EasyLang. I think they also started from Basic.

| +1 Kudos for providing the repl.it tool.
|
| The classroom/assignment feature [i] is absolutely brilliant!
| Also, now might be a great time to do another [ii] hackathon.

| Replit sounds awesome, especially once you put it this way
