DView vs. ResultsViewer

This is just a request to see if maybe ResultsViewer could be kept on/reinstated for new OpenStudio releases? DView takes forever to open and when it does, it has very limited capabilities. In contrast, ResultsViewer allows for very clear selection of data to be shown and also has a data picker, plus it is a lot faster even with large data files. One particular example I recently had to deal with is design day simulation runs. In ResultsViewer, I can easily pick the design day I want. In DView, I just got shown one day and it was not clear which day that was and how to select other days, if that were even possible.

I'm pretty sure that ResultsViewer isn't coming back as part of OpenStudio. For now, you can always get the OpenStudio 2.2 package from here and install only ResultsViewer. When opening simulation results, you may see a message about the EnergyPlus version being unsupported, but in reality that'll only be a problem if/when the EnergyPlus SQLite file changes enough to cause problems. With 8.8 I have not had any problems.

Once the file changes, well, I like ResultsViewer enough that I've carved it out of OpenStudio history and set it up in it's own repo here. This is strictly a on-my-own-time thing, so it presently doesn't build and it isn't likely to for some time. Taking it out of the OpenStudio context left a couple of gaping holes and the last build resulted in 300+ errors, but on the up side I've upgraded to C++17, gotten rid of boost, and the compiler user to just give up because there were too many errors to count. I'm filling in the holes as I go. Contributions are welcome, etc., etc.

@Jason DeGraw, I had a question which Rob addressed me to this page.

To install previous versions of Results Viewer, I have downloaded this file but unfortunately, I do not know how to install Result Viewer (I do not see any .exe files or something like that)?

My current OpenStudio is version 1. 11 (I want to install older versions of Results Viewer on it).

Jason tells you how to do it in his answer, above. You get an older installer and run it, but only check the box for Results Viewer. You will end up with a program group for the version of OpenStudio installer you just ran, and the icon for Results Viewer that came with that version will be in there.

@Mahdi Ghodsi Right, there's no executables from my fork yet. I think I'm down to about 10 errors that need fixing. Getting an older installer should give you an older version of ResultsViewer. The recent installers give you the option of installing only ResultsViewer, if you go far enough back I think that option may not be available.
