I have recently updated the plugin using moodle 3.9. We now receive the following when clicking the run or check icons.
Call to undefined function hrtime
On research the hrtime function is new tp php 7.3. moodle 3.9 is surpposed to support php 7.2. Does this now mean I need to upgrade all my php libraries. Help this was working fine before, I fear php upgrade may knock a lot more out.

Hello Juan.
Happy new year.

I actually have a problem with UI in VPL.
When I make an activity, my "Jump to" section is disappear.
(float-left, jump to activity, flot-right all gone)
This happens only in VPL.
Other activities are ok.

Do you know this problem?
If you know the solution that I can fix, plz tell me.

Hi,
We have been facing some issues for the past 6 days "Unable to run HTML/CSS/JS files in VPL, although Python files run successfully. Need help resolving the issue."

The "ID Number" is automatic generated. We are not able to set "ID Number" for VPL, it does not store custom value.
We need ID Number to use in formular in Gradebook.

How to fix this?

I'm trying to edit some old test cases for VPL activities we have on our moodle. And I'm unable to edit the test case, in description it just shows the test case sort of read only in a navy background frame but no editor. What am I missing we are running VPL version 4.1 (2023042712) and Moodle 4.1.

The same think happens when a create a new VPL activity, in description I only see the icons and no editor. Any help would be much appreciated.

No issue, found it!

Dear Steve Wentworth,

Thank you for bringing this to our attention.

Given the extensive use of JavaScript in the VPL plugin, it is possible that the editor may experience disruptions after an upgrade. I recommend the following steps:

1. The Moodle administrator should “purge all caches”. This can be accomplished by navigating to “Site administration -> Development -> Purge caches”.
2. Some users may also benefit from clearing their browser's cache. This can be done by pressing “Ctrl + F5”.

Additionally, I'd like to inform you that the current VPL version you are using, 4.1, is not the latest. Version 4.2 is available and is compatible with Moodle 4.1. Please note that VPL versions are not necessarily tied to the corresponding Moodle versions.

I hope this resolves your issue. If you continue to encounter difficulties, please do not hesitate to reach out.

Best regards,

hi juan carlos, i interested to use it on our inhouse Learning Management System. can i contact you for detail discussion ?

nex- activity previous-activity not appearing.. kindly help to fix this UI

compatibility for Moodle 4.5 ?

Dear WAT Guyane,

Thank you for your inquiry.

We are currently conducting compatibility tests for the newly released Moodle 4.5. In our initial manual review, we haven’t identified any major issues so far. However, we are working to address some challenges with the Behat tests, which are not running due to interface changes in Moodle 4.5.

Hi, I’m trying to create test cases in a way that only certain test cases are marked as sample test cases and that they receive a score of 0 even if the output is correct, similar to how it works on HackerRank. Could you guide me on how to configure test cases to function this way? I want them to appear as sample cases but not contribute to the overall score. Thanks!

Please help

Hi Sandipa,
First, I would like to point out that this is not the best way to ask questions, as there is no proper thread for each question and answer. Please, next time use the VPL forum (discussion area) for this kind of communication.
Regarding your problem: the VPL system checks for the use of tkinter in your code to automatically switch to GUI mode. However, in some cases, it may not detect it correctly. To solve this, simply add a comment mentioning tkinter in your code.
Also, remember not to name your file turtle.py, as this can cause conflicts with the standard Python Turtle module.
Here is an example you can follow:
import turtle
# Tkinter
screen = turtle.Screen()
screen.bgcolor("white")
screen.title("Turtle Example")
# Create a turtle
my_turtle = turtle.Turtle()
my_turtle.shape("turtle") # Make the turtle look like a turtle
my_turtle.color("blue")
my_turtle.speed(3)
# Move the turtle
my_turtle.forward(100) # Move forward 100 units
my_turtle.left(90) # Turn left 90 degrees
my_turtle.forward(100)
my_turtle.left(90)
my_turtle.forward(100)
my_turtle.left(90)
my_turtle.forward(100)
# Finish
turtle.done()
Please try this and let me know if you still encounter any issues.
Best regards,
Juan Carlos Rodríguez
