![]() ![]() You don't have to restart the application. If you make further changes to the JavaScript code, just re-execute a test program to get the latest changes. When you run the program, it will use your latest JavaScript changes. Change the version number in a program to 3.1dev that is, 0.1 greater than the current 3.0, plus dev. Suppose the current version of Web VPython is 3.0. At the start of ide/api.py, if the variable "localport" is XXXX instead of 8080, to start up the application you must executeĭev_appserver.py -port=XXXX /./glowscript/app.yamlĪnd the browser must point to "localhost:XXXX". More precisely, 8080 is the default port number. /glowscript (on Windows, use backslashes instead of slashes).Īlternatively, change directory ("cd") to the glowscript folder you downloaded, and execute Where the location of the Web VPython code is at Gcloud components install app-engine-pythonĭev_appserver.py /./glowscript/app.yaml In a command-line terminal, execute the following statement (on Mac or Linux, you may need to preface this command with "sudo"): Run this installer, which will install a Python 2.7 (which is required by the Google software) unless you uncheck "Bundled Python". Next, if you have not already installed the Google Cloud SDK ("Software Development Kit"), do this:Ĭlick the Download button for "Install and initialize Google Cloud SDK" and then click "Cloud SDK installer". (3) Install the Google Cloud SDK for PythonĪt /appengine/downloads choose Standard environment Python for your platform. (2) Download the Web VPython source filesĪt the repository on GitHub,, click "Clone or download" and then clone the repository, or click on "Download ZIP" and unpack the contents of the glowscript-master folder into a new local folder named glowscript. (1) Watch a YouTube overview of the VPython architecture:Īt a later time you should also study this document: An excellent, up to date textbook on JavaScript is available at. If you want to be able to contribute to developing VPython, here are the (rather complex) steps required to be able to run locally with changes that you make to the code, almost all of which is written in JavaScript (there is also some Python server code and some html code). Even if you do not wish to help develop VPython, you might want to install the GlowScript machinery on your computer, to be able to use it without access to the internet. Yet another option is to follow the instructions below. As long as you don't import Python modules other than vpython, you will also be able to run the program at without having to make changes. At see the section on using VPython with installed Python. Before going offline, use the download options at to get local copies of your programs.Īnother option is to install Python and the VPython 7 module. At, in the section on using VPython without installing software, see the instructions for how to use Web VPython without an internet connection. When internet access is missing or poor, you may find it useful to run locally, independent of the internet. ![]()
