Generating word searches for fun and profit
(Above: A Word search generated with the tool below)
A little while ago I was asked about generating a wordsearch in a custom shape. I thought to myself "someone has to have built this before...", and while I was right to an extent, I couldn't find one that let you use any shape you liked.
This, of course, was unacceptable! You've probably guessed it by now, but I went ahead and wrote my own :P
While I wrote it a little while ago, I apparently never got around to posting about it on here.
In short, it works by using an image you drop into the designated area on the page as the shape the word search should take. Each pixel is a single cell of the word search - with the alpha channel representing whether or not a character is allowed to be placed there (transparent means that it can't contain a character, and opaque means that it can).
Once done, you can start building a wordlist in the wordlist box at the right-hand-side. It should rebuild the word search as soon as you click out of the box. If it doesn't, then you've found a bug! Please report it here.
With the word search generated, you can use the Question Sheet and Answer Sheet links to open printable versions for export.
You can find my word search generator here:
The most complicated part of this was probably the logistics behind rude word removal. Thankfully, I did't have to find and maintain such a list of words, as the futility npm package does this for me, but algorithmically guaranteeing that by censoring 1 rude word another is not accidentally created in another direction is a nasty problem.
If you're interested in a more technical breakdown of one (or several!) particular aspects of this - let me know! While writing about all of it would probably make for an awfully long post, a specific aspect or two should be more manageable.
In the future, I'll probably revisit this and add additional features to it, such as the ability to restrict which directions words are placed in, for example. If you've got a suggestion of your own, open an issue (or even better, open a pull request :D)!
