Most appropriate sub-area of p5.js?
- Core/Environment/Rendering
- Typography
- Friendly errors
p5.js version
1.9.2
Web browser and version
Firefox 125.0.2
Operating system
Linux Ubuntu 22.04 LTS
Steps to reproduce this
Steps
- Create a new project.
- Pass an invalid parameter, such as a number or string, to
textWrap()
insetup()
.
Snippet
function setup() {
createCanvas(400, 400);
textWrap(50);
}
Notes
When I first tried to use textWrap()
, I wrongly assumed it took the maximum width, in pixels, of the text before wrapping occurred, so I did something like textWrap(width * 2 / 3);
. The canvas disappeared and no error was given. I believe I've seen this behavior before with other methods but I can't remember which ones.

It seems that the textWrap()
function (src/typography/attributes.js#L541) does do a simple if then
check to throw
an error, but doesn't use p5._validateParameters()
.
