Pretty sure that’s a result of defspec, not circleci.

Maybe this is a repeat question... I am a newbie and I have just stumbled upon spec in Clojure. I was wondering if spec can somehow be used to replicate regular expressions? e.g. say we have a sentence pattern like "Sam is a good boy"... We want the sentence to be parsed by an expression parser to extract words like this: "<name> is a <adjective> boy". We can do this in regular expression. I was just wondering if somebody has tried this using spec?

Spec is not intended to be used for text processing

I am using https://github.com/flatland/clojure-protobuf library for serialization and it strips all the default values/fields not provided while sending it over the wire(which is understandable) but also when deserializing at client side, it doesn’t add those default values or missing fields(with default values) back. I checked https://github.com/golang/protobuf golang library which returns those default values. Does anyone have idea why this library doesn’t return default values?

Is there a way to create a sorted-map that is sorted by the values?

I am running an sh job for side effects and I want to be notified when it finishes. However, if it the execution throws an error it never does finish:

user> (future (sh "non-existant-command-fails")) ;; never finishes

This does not work either:

(future (try (sh "non-existant-command-fails") (catch Exception ex {:error ex})))

what does work mean? @(future (try (/ 1 0) (catch Exception _e {:it :threw}))) returns {:it :threw}.

Not working: it never finishes. But the above (with @) is blocking. I'd like to dispatch a job and then be notified when it finishes.

When I do:

(def f (future (try (sh "non-existant-command-fails") (catch Exception ex {:error ex}))))

#object[clojure.core$future_call$reify__8477 0x652ce654 {:status :ready, :val {:error #error { ......}}}

Are you doing something different?

The above works, but if I add a callback function (just println in the below example) the callback is never used:

(def f (future (try (sh "non-existant-command-fails") (println "hoi") (catch Exception ex {:error ex}))))

That’s because the exception was thrown before the print

That is how I was hoping to be notified of the job being finished (or having errored)

You could use a finally block?

I see the reason why, I just wonder how to get around it 🙂

Ah, I'll try 🙏

Anyone know any good time zone conversion libraries?

Depends what you mean by that — for Clojure, I’d just use Java Time directly for most time/date stuff.

Anyone using Datadog APM with Clojure? Or even more in particular ... using Clojure + open telemetry with Datadog APM?

Is this expected behavior?

I think this may already be logged (has to do with the coercion/casting path for primitive long vs object Long) but please ask these kinds of things on https://ask.clojure.org

there are a small cluster of bugs in this area

there are several questions there that seem like the same thing already

if you start asking a question on ask.clojure btw, it will suggest similar existing questions
