The Envision code playground

The Envision code playground is a programming environment made publicly available by Lokad. The playground is accessible from https://try.lokad.com. The playground does not require registration and is intended for educational purposes.

Code, Files and Output

The playground includes three tabs.

• The Code tab is a code editor for the Envision programming language.
• The Files tab is a minimal file system, to be processed by the Envision script.
• The Output tab shows the dashboard as generated by the Envision script.

Clicking the Output tab triggers the execution of the Envision script. Afterward, you can return to Code to resume editing the script, if desired.

Sessions

A session includes an Envision script and a set of files. The session reflects a persistent state of the playground. The session allows resuming the use of the playground while preserving the former entries. Each session may be reached through two URLs:

• A private URL: this URL grants access to all the data of the session - both script and files - as well as grants the right to further edit the session.

• A public URL: this URL also grants access to all the data of the session. However, it creates a new session, copying the original. The original session is not impacted by edits made on the copied one. Both URLs can be accessed by clicking the Share button. In the specific case of a professor composing a programming exercise for his students, the professor would create a session associated with the exercise. He would then share the public URL of this session with his students. The professor would keep the private URL to himself in case there is a typo that needs to be fixed in the original exercise.

Check out this public session that comes a sample dataset illustrating a simple inventory replenishment situation.

Acceptable use

Keep it legal and professional. There is no usage restriction for this environment beyond what common sense dictates.

Commercial use is largely acceptable (the fine print is given below). For example, this environment can be used as part of a paid training program. This environment can also be used as part of a consulting mission. Regardless of commercial application, Lokad does not expect any kind of fees to be paid. Conversely, Lokad does not make any commitment concerning the allotment of computing resources (see below).

We reserve, in perpetuity, the right to adjust, at any time, the allotment of computing resources for this playground. Our hope is to keep the allotment high enough to support tasks that would reasonably qualify as an educational undertaking, or as small-scale supply chain analysis, but we do not commit to any specific allotment of resources. These adjustments can/will be made whenever the company deems fit, and Lokad is under no obligation to advertise these changes, neither in advance nor after the fact.

Data and security

The playground is designed for the public sharing of educational materials. Data submitted to the playground is made publicly accessible through URLs without authentication. Thus, do not submit any data to the playground that you are not in a position to publicly share.

Any data submitted to the playground remains the property of its original owner. Lokad does not claim any rights to, or ownership of, any data submitted. Lokad will not use this data for any purposes besides operating and improving the playground itself. In particular, Lokad will not resell uploaded data. Conversely, Lokad makes no commitment to preserving the data.

If you want to remove any data from the playground, write an email to contact@lokad.com specifying the URLs that you wish to see removed.

Besides the public access to the playground itself, we will not grant access to this data to any third party except those involved with the infrastructure of the playground. This includes, for example, the cloud computing platform we use.
