// This script takes the current url and converts the path and query
// string into just a query string, and then redirects the browser
// to the new url with only a query string and hash fragment,
// e.g. https://fifthlang.github.io/l/foo/bar?a=b&c=d#qwe, becomes
// https://fifthlang.github.io/?/foo/bar&a=b~and~c=d#qwe
// Note: this 404.html file must be at least 512 bytes for it to work
// with Internet Explorer (it is currently > 512 bytes)

// If you're creating a Project Pages site and NOT using a custom domain,
// then set pathSegmentsToKeep to 1 (enterprise users may need to set it to > 1).
// This way the code will only replace the route part and not the real directory.
// For example, if your repo is at https://username.github.io/repo-name,
// then set pathSegmentsToKeep to 1 so that routes like /repo-name/about will
// become /repo-name/?/about, and not /?/repo-name/about.

The pathSegmentsToKeep value should be 1 for GitHub Project Pages sites. Since this appears to be hosted at 'aabs.github.io/fifthlang.github.io', setting it to 0 will cause incorrect URL rewriting that strips the repository name from the path.

Suggested change
var pathSegmentsToKeep = 0;
var pathSegmentsToKeep = 1;

var l = window.location;
l.replace(
l.protocol + '//' + l.hostname + (l.port ? ':' + l.port : '') +
l.pathname.split('/').slice(0, 1 + pathSegmentsToKeep).join('/') + '/?/' +
l.pathname.slice(1).split('/').slice(pathSegmentsToKeep).join('/').replace(/&/g, '~and~') +
(l.search ? '&' + l.search.slice(1).replace(/&/g, '~and~') : '') +
l.hash
