kandi X-RAY | clojure Summary

clojure is a CSS library typically used in Serverless, Function As A Service applications. clojure has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Clojure is a simple, powerful and fun language to develop any and all applications. It has a simple syntax that is quick to learn and a wide range of Clojure libraries to build any kind of apps and services. Its also easy to use any existing Java / JVM Language code or libraries as part of your Clojure apps. In this workshop we take a hands on approach where everyone takes Clojure code and experiments with it using the REPL (interactive runtime environment). You will quickly get a feel for Clojure by evaluating, breaking, fixing and extending code in the REPL, all the while getting instant feedback on what your code is doing. As we work through code we will discuss the concepts behind Clojure, including functional programming, "pure" functions and a stateless approach with persistent data structures, changing state safely, Java interoperability and tooling around Clojure.

QUESTION

Clojure: overriding one function in a library

Asked 2021-Jun-09 at 22:12

This question is off the back of a previous question I asked here a few days ago. One of the comments was that I should dispense with the Ring middleware for extracting query parameters and write my own. One alternative that I thought I'd play with was harnessing the existing one to get what I want and I've been doing some digging into the Ring source code. It does almost exactly what I want. If I write out how I understand it works:

A middleware has the function wrap-params which calls params-request
params-request adds a params map to the request map, calls assoc-query-params
assoc-query-params eventually calls ring.util.codec/form-decode on the incoming query string to turn it into a map
form-decode uses assoc-conj to merge values into an existing map via reduce
assoc-conj's docstring says

Associate a key with a value in a map. If the key already exists in the map, a vector of values is associated with the key.

This last function is the one that is problematic in my previous question (TL;DR: I want the map's values to be consistent in class of either a string or a vector). With my object orientated hat on I would have easily solved this by subclassing and overriding the method that I need the behaviour changed. However for Clojure I cannot see how to just replace the one function without having to alter everything up the stack. Is this possible and is it easy, or should I be doing this another way? If it comes to it I could copy the entire middleware library and the codec one, but it seems a bit heavyweight to me.

...

I disagree with the advice to not use Ring's param middleware. It gives you perfect information about the incoming parameters, so you if you don't like the default behavior of string-or-list, you can change the parameters however you want.

There are numerous ways to do this, but one obvious approach would be to write your own middleware, and insert it in between Ring's param middleware and your handlers.

ClojureScript: How to access (not just print) the result of an HTTP GET request

Asked 2021-Jun-06 at 13:46

I am trying to build a simple client-server system with Clojure (server) and ClojureScript (client).

The server side is OK (everything is green on the browser's console, no CORS problems, etc.); the response is plain text ("true" or "false"). On the client side I am using basically the function included in the official cljs-http website

QUESTION

How to suppress output of exception while running unit tests in Clojure

Asked 2021-Jun-05 at 12:24

I am using leiningen for clojure, and I have a suite of Unit-tests that run when I run lein test.

I noticed that in some of the tests, we want to test exception handling scenarios and for that we throw an exception. The problem is, it returns a full stack trace in command line which I often take for something bad happened, when it's really not.

Coming from the JS world, I saw that we can suppress exceptions which we want to mark it as suppressed in frameworks like jest, is there any option with leiningen or clojure for that?

ANSWER

Answered 2021-Jun-01 at 10:32

The key thing to remember is that functions are data. Whilst you can't dynamically create types very easily (as opposed to instances that implement an interface, via reify), you can statically create a class which then proxies your functions.

First let's make the :task of the job-inventory a function.
