Here's what kc3 code looks like (taken from [1]):
def route = fn (request) {
if (request.method == GET ||
request.method == HEAD) do
locale = "en"
slash = if Str.ends_with?(request.url, "/") do "" else "/" end
path_html = "./pages#{request.url}#{slash}index.#{locale}.html"
if File.exists?(path_html) do
show_html(path_html, request.url)
else
path_md = "./pages#{request.url}#{slash}index.#{locale}.md"
if File.exists?(path_md) do
show_md(path_md, request.url)
else
path_md = "./pages#{request.url}.#{locale}.md"
if File.exists?(path_md) do
show_md(path_md, request.url)
end
end
end
end
}
