So I've read the descriptions of what EJS 5.3 will do, and what EJSS 6.0 will do.
I'm currently using EJS 5.3 (Java version: JRE 8, Windows 10) I've created a new simulation: Lagrange Point the .zip containing the .ejs file is attached This simulation still requires finishing touches, but it is functional.
Next step is to port this simulation to EJSS.
Is it possible to use EJS 5.3 and EJSS 6.0 side by side?
The reason I ask: In Windows, EJS writes two configuration files: .ejs.txt .ejs.console.txt
My understanding is that the location where EJS writes those configuration files is hard coded. So I assume that if I try to use EJS 5.3 and EJSS 6.0 side by side each will overwrite those two configuration files. Of course, most of the settings will be identical. Still, one setting is different: whether to generate Java simulation or JS simulation.
Hi Cleon, the conversion process can be done on this file EjsS_5.3_190423-beta.zip, i recommend this new ejss editor because it is the latest 2019 ejss5.3, i speculate this version will be improved on instead of the 2018 version on Paco's server.
thank you for verifying the simulation can be ported, and thank you for the overview of how the porting proceeds. Screenshots are always very helpful!
Since my simulations are very elaborate it's probably less complicated for me to recreate the same simulation from scratch. That way I can test at intermediate points, allowing me to keep track of what I'm doing.
So my preferred workflow would be that I have a source simulation that is completely accessible, and the creating-from-scratch version separate from that.
But it is my understanding that EJS is hardcoded to have only one instance of the EJS console running.
My preferred workflow would be to have two completely separate workspaces, one for EJS and one for EJSS, but it appears that EJS/EJSS is hardcoded against that.
It just occurred to me: I can set up an instance of EJSS on a separate computer and operate that version of EJSS using remote viewing software. (I'm familiar with Teamviewer, for instance.)
Still, I would prefer running independent instances of EJS and EJSS on the same computer.

Hi Cleon, Yes. You can use them side by side, though in principle one should use only one. If I remember well, the main information stored in those hidden files that can bother you a bit is the last simulation opened. (It will change depending on which version of EJS you close last.) But, if you uncheck the "Load last file" option, that won't be a problem.
As you know, EJSS 6 is the evolution of EJS to support ONLY JavaScript simulations. The reason is that Java evolved to version 10 and some features of it "broke" how EJS JARs simulation files in Java. Hence, we decided to split the Java and Javascript versions of EJS. If you use the Java version, you'll need top stock to Java 8. If not, you can move to Java 10 (and beyond).
(funny thing: you are referring to the configuration files as 'hidden info files'. I'm like: what do you mean hidden? Then it dawned on me: in Unix environment there is that convention that if the filename starts with a dot then the OS is supposed to treat that file as hidden. But on Windows that file isn't hidden.)
I appreciate the problem: All software needs to have a way of preserving state during off-time; the time between the software being closed and opened again. Users expect that continuity.
The location where to look for the configuration file has to be hard coded.
That is why, I presume, that in the case of software that is also available in portable form that portable version is a distinct version. (The portable version looks for the configuration file in the same directory as where it resides itself.)
So yeah, how do you straddle the transitional period.
To be clear: alternating between EJS and EJSS doesn't cut it for me. I'm looking for a solution to have EJS and EJSS simultaneously available, fully functional, including the 'View' tab.
The EJS console has several pull-down menus, the bottom one is a pull-down menu for selecting either Java or Javascript.
The following had not occurred to me, so I just tried it. - When I start the EJS console it automatically starts an instance of EJS - I use the pull-down menu to change to the setting to 'Javascript'. - I click the 'launch' button, starting a second instance of EJS, and this second instance is EJSS
Looking back: I had blindly assumed that the EJS console would not allow a Java-instance and a Javascript-instance to co-exist. I had blndly assumed that if you have multiple instances they must either be all EJS-instances or all EJSS-instances
Feature request: Add an option in EJSS 6 to start a read-only instance of Java-EJS
Ah, so I checked that too (using an EJS 5.0 console and an EJS 5.3 console)
The EJS console does let me start another console instance, but there's a warning: "An instance of the EJS console is already running. Do you want to run a second instance of the EJS console?"
I'm not using Java for anything else, so in my case I can keep Java 8.
