Web VPython editor unusable on iPad Pro

[Joe Heafner]



The Web VPython editor has apparently become unusable when using my iPad Pro (running iPadOS 15.6.1) with and without Apple’s Magic Keyboard. I’m trying to code the following loops:

lambda i, j, k: (i-j)*(j-k)*(k-i)/2

for i in 1, 2, 3:

for j in 1,2,3:

for k in 1,2,3:

print (i,j,k)

But I can never get past the first level of indentation. When I hit “return” after the second for statement, there is no indentation and pressing TAB makes the cursor vanish completely. This happens both with the iPad’s built-in virtual keyboard and my Apple Magic Keyboard. Restarting the iPad had no effect. This is the first time I’ve encountered this problem.

I know in the past there has been mention of incompatibilities with the ACE editor and iPad, but two summers ago I created an ACE installation here

and it works flawlessly with every device I’ve tested it on, including various iPads and iPhones. I’m not sure what’s going on and I don’t know where to look to debug this. Just thought I’d pass it along and ask whether or not anyone else has experienced this.

While my classes have not encountered this particular situation, we found that using Glowscript on IPads was very tricky:

- certain browsers worked, while others didn't work with Web VPython.  Safari, in particular, gave us many problems; we avoided this at all cost.

- some iOs versions were very problematic.  In general, ensuring the Ipad is using the latest update has been a good idea.

- AutoCorrect of punctuation absolutely needs to be off. Single quotes were being changed to slanted quotation marks, which VPython doesn't recognize, for example. I can't imagine that colons are autocorrected in any way, but if they were, this would explain the lack of indentation.

Good luck!

I just tried this using Chrome on a brand-new iPad running 15.6.1 and the only thing wrong (with or without physical keyboard) was that upon pressing Return after the 2nd colon there wasn't the expected additional indent, and Tab failed; I had to enter spaces instead. There was no problem with single quotes, nor did I  have to do anything special about AutoCorrect.

Joe, what browser were you using?

I was using Safari as it ships with iPadOS 15.6.1. I confess I had not tried Chrome or Firefox today on the iPad. I also didn’t see any autocorrect issues, and spaces worked for indentation.

Glowscript in Safari auto-indents after a colon on my IPad. Version 15.6.1.
