Newspeak

Newspeak is a new programming language in the tradition of Self and Smalltalk.

For pre-built VMs and images, see newspeaklanguage.org/downloads.

If you intend to develop with the new Web IDE, read on:

  • The Web IDE is still experimental. Caveat Emptor.

First, download the app. For MacOS and Linux, you can use the Electron app

You can also download a directory from which the app can be served locally to any web browser. For all platforms

Unzip the download. The directory contains a script, serve.sh, that will try and serve using python web server. You may prefer this option if you're on Linux, or want a (much) smaller download.

Just in Case

If you feel you must rebuild the system from scratch, here's how:

Set up a directory for your work, say, nswasm

mkdir nswasm
cd nswasm

and then clone this repo under it.

In the same directory, clone https://github.com/newspeaklanguage/primordialsoup.

To be clear: you should now have a directory named nswasm, with two subdirectories; newspeak, containing this repository, and primordialsoup, containing https://github.com/newspeaklanguage/primordialsoup.

Follow the instructions at

https://github.com/newspeaklanguage/primordialsoup/blob/master/docs/building.md

in the primordialsoup repo to set up the required dependencies for primordialsoup, and switch to the extraRevs branch.

cd primordialsoup
git checkout extraRevs

You'll also want to download CodeMirror from https://codemirror.net/.

Place it in the top level of the newspeak repo.

In the top level of the newspeak repository, you should find the script build.sh. It assumes Emscripten is in ~/software/emsdk/; you will want to adjust that to reflect where you have installed emscripten.

Running build.sh should build the psoup VM as well as the vfuel file for the Newspeak IDE.

source build.sh

HopscotchWebIDE.vfuel should now exist in the ./out subdirectory of the newspeak repository.

You can access it by running a web server, using the serve.sh script:

source serve.sh

The serve.sh script will run a python web server and will tell you that you can access the IDE by pointing a web browser at:

http://localhost:8080/primordialsoup.html?snapshot=HopscotchWebIDE.vfuel

You can edit server.py to change the port used. It is often convenient to have the web server running all the time.

If you make changes to the Newspeak code used in the IDE, just run build.sh again.

Another option is to rebuild the vfuel file for the IDE, and copy it into the electron application. That way you don't need to run a web server. The script updateApp.sh provides a template for this. On a mac, it should work out of the box:

source updateApp.sh

Otherwise, you'll need to modify it as described in the script.
