[WINDOWS] On startup from the zip distrubtion main.R is not run

[gjwgit]

Description

For the zip distribution of the rattlng package for Windows, when running the rattle.exe on Windows, after R starts up in the CONSOLE it does not run the main.R script. On Linux and MacOS the main.R script is run on startup.

This task is to investigate why main.R is not run on starting up rattle.exe on Windows.

[gjwgit]

Note that I can paste the contents of main.R into the CONSOLE to have it run and then rattle will operate for that session as expected.

Perhaps it just needs main.R to be loaded later on - perhaps on the first (or every) loading of the dataset

[gjwgit]

Unfortunately this fix causes the following error for Linux:

flutter run --device-id linux
Launching lib/main.dart on Linux in debug mode...
Building Linux application...

Error: Build process failed

Reverting for now.

See TerminalStudio/flutter_pty#16. not test for linux so sorry for the issue introduced. I could create a fork with those fix and then we depend on that repo if you agree.

Let's give it a go.

Does this solve the issue for you @Lutra-Fs? I still do not have main.R being pushed into the Terminal on startup in Windows.

[gjwgit]

To investigate

• Copy and paste in the Console no longer functional?
• Move main.R into dataset_prep.R instead

[gjwgit]

I will stick with the main.R inside dataset_prep.R for now - there is a small delay after loading the dataset before the pages are populated but might be okay.

I didn't have that version in my pc so far. Will checkout the commit and see what happened here.

Just have a quick check and I could confirm that in my build main.R works fine even the loading is in start stage.
