Using loadString on .txt file in Javascript mode

in Processing with Other Languages • 3 months ago

I'm trying to read a simple .txt file that I've created in javascript mode. However, it either doesn't read the file or removes it from the web-export folder. Is there a simple way to just read a .txt file in javascript mode?

sure. the simplest way is the way set forth in the docs:

http://processingjs.org/reference/loadStrings_/

assuming you've already tried that, we'll need to see your code, preferably a minimum working example, to figure out what else is going wrong.

Ok, I created a data folder and it seems to be working. But why does this processing page say that processing.js doesn't use a data folder?

holy smokes! amazing question. can't believe i hadn't put that together.

documentation bugs are filed in the same place regular bugs are, here:

https://processing-js.lighthouseapp.com/projects/41284-processingjs/overview

if you don't want to create an account to file the bug, let me know and i'll file it for you. i'll link back to this thread and give you credit of course.

If you want to file it, that would be fine. Just glad I got it sorted out. Thanks.

i've been doing some tests, and what is being said isn't wrong in one sense so much as it isn't very clear.

when using javascript mode, you do need to have a data folder because you are using it within the IDE. You'll notice that after you run it, if you look in the web export folder, there is not a data folder, and the file has been moved to the same as the pde is in.

the place where you read that was under an explanation of javascript mode so it's not correct. still it is technically the case that when using pjs you do not need a data folder, but when using javascript mode, you do.

It makes sense: somehow, most sketches should run the same in Java and in JavaScript mode, so, for compatibility reasons with the Java mode, the JS mode uses the data folder. A constraint that disappear after export.
Indeed, it needs a clarification, so the bug report is still useful.
