Thanks for the contribution! If you don't mind, could you actually grab a package like shell quote and stick that in there? It's more of an edge case, but this would also break if someone used quotation marks in their path; shell-quote should fix it permanently :)

Oh, you're right. I didn't think about that possibility. Also, (sorry I'm still getting used to these commit standards...) how should the title/body of the commit be?

The commit you have looks good. Don't worry about it too much though, we can squash merge and fix it up.

Just pushed the commit using shell-quote. I still think it has to have some improvements (maybe implementing a function to escape the path in the script itself?) because apparently webpack's argument parser only accepts double quotes instead of single ones (shell-quote's default) at the start/end of the parameter, so I had to remove both the first and last characters and replace them with double quotes.
Taken from the module code: character.replace(/([#!"$&'()*,:;<=>?@\[\\\]^`{|}])/g, '\\$1') inside a map should escape all special characters. (and then it would add double quotes to the start and end of the string)
Tell me what you think is best.

Whoops. The current code won't work for non-spaced paths (lol). I'm working on it to make it run. (I'm probably going to implement the escape function inside the script instead of using external modules)

I would recommend against that, shell escaping is surprisingly hard (as indicated by the number of commits and issues in the shell-quote repo!)

Webpack shouldn't really care about double quotes in particular, the OS' shell should itself be the one delimiting arguments. E.g. in your basic C program, your main function can take arguments; parsing those is not part of the C standard library or compiler, it's the OS.

What happens if you pass that whole array [--port, String(port), '--config', config, '--color'] through shell-quote?

Hi, I'm not sure that (in this case) the OS is parsing the parameters.

As you can see in the image, when I try to run webpack-dev-server --port 13370 --config 'C:\Users\Rafael\Desktop\teste com espacos\amazingly-incredible-bear\webpack.config.js' --color webpack tries to find the provided path in the CWD. (single-quoted)
When the path is double-quoted, it runs without any problem.
Also, the quote function from shell-quote returns a string and not an array because they join the array when returning the result.
Even if I try to put the array through shell-quote, which returns --port 13370 --config 'C:\\Users\\Rafael\\Desktop\\teste com espacos\\amazingly-incredible-bear\\webpack.config.js' --color, and run the dev server manually, it returns the same error. Error: Cannot find module 'C:\Users\Rafael\Desktop\cdk\'C:\Users\Rafael\Desktop\teste'
