Url Parsing in Racket
Here’s the translation of the URL parsing example from Go to Racket, formatted in Markdown suitable for Hugo:
Running our URL parsing program shows all the different pieces that we extracted.
In this Racket version:
We use the net/url
library for URL parsing.
The string->url
function is used to parse the URL string into a URL object.
We access different parts of the URL using functions like url-scheme
, url-user
, url-password
, etc.
For query parameters, we use form-urlencoded->alist
to convert the query string into an association list.
Racket doesn’t have a direct equivalent to Go’s net.SplitHostPort
, so we just display the host and port separately.
Error handling is implicit in Racket, so we don’t need explicit error checking as in the Go version.
This example demonstrates how to parse and extract information from URLs in Racket, covering the same concepts as the original Go example.
