Virtual Programming Lab

Hello Slobodan,
the VPL evaluation has nothing to do about any internal representation of information of evaluated programs. The evaluation process gives the input to the evaluated program. The evaluated program manages the input data.
If you write a program that take the data from the standard input, the data at the "input=" statement must be the same that you type as input when you run the program.
Best regards.

Hi Juan,
I have one question regarding the VPL evaluation phase. I was thinking how to evaluate some C/C++ program that takes an array (dinamically allocated) as the input. I do not see that the default evaluation scripts is capable to read a variable size array of characters.
Since I am a begginer, I suppose that this problem has been already solved. Can you help me?
Thanks,

Hello Deepa,
I haven't test to use an application server for Java in a jail server, but I think that it is possible to run it with some limitations. You must be aware that every execution start with the same data from the same point. If you manage to run a application server in user space then you 'll be able to run it in a jail server.
Note that
- You must choice a different port for every application server
- You can use firefox in the jail as browser
- The execution script must generate vpl_wexecution (not vpl_execution) to run in graphical mode
Best regards.

Can we plug in other enviornments like j2ee , spring , hibernate into jail server? How do we do that

Hello Venkatesh,
I will try to answer your questions.
1) I can't answer your question about automatic evaluation in C language because I can't reproduce your situation. Please, send me the definition of test cases and the code in C language that fails then I will reproduce your problem and try to resolve it.
2) Does graphics programs in C can be evaluated in VPL? This question really is not about. If you can test graphics programs in C outside VPL, then it's very possible to reproduce the test at VPL.
3) Increasing the font size temporarily, just push "CTRL and '+' key" in your browser. To increase the font size temporarily, just push "CTRL and '+' key" in your browser. Increasing the font size permanently is more difficult because it's in the code.
Please, do the next question at the forum

In VPL the font size is very small we find it very difficult to write programs. How to increase the font size of the editor.

Hi Juan,
Does graphics programs in C can be evaluated in VPL??

Hi juan,
Thanks for the wonderful VPl which you have created. We are a small development team located in India and we have customized your VPL for our needs. While working we have faced a small problem is that when we get a character input in C Language, test case gets failed. All the test cases gets evaluated only if i declare as a string.

Hello gm pepz,
If you are logged as teacher you can use any button (run/debug/evaluate). If you want to activate these buttons for students, you must go to the VPL activity that you want to manage and go to "Settings->Execution options" and select the features that you want to offer to your students.
Best regards.

hello everyone, I have downloaded this plugin and successfully added it into my Moodle app, but when I ran the plug in and wrote a sample code on it, it doesn't have Run button or other functions that would allow me to test my code.

Sorry Zbigniew,
It is my fault, we are migrating the server to other system and it is taking more time than expected.
Best regards

Hello,
Can I ask why the website of plugin is offline?
Best regards

Hello James,
to resolve the issue of the editor do the following:
Add the following properties to the class vpl_ide_root
text-align:left;
direction:ltr;
in file "editor/VPLIDE.css"
to get a complete solution see changes in v3.1 in github
https://github.com/jcrodriguez-dis/vpl/tree/v3.1
Notice that the editor (http://ace.c9.io) can't manages correctly embedded rtl text .
Best regards.
