QUESTION

IllegalArgumentException using "proxy" in Clojure

Asked 2022-Mar-03 at 20:18

I followed this tutorial to learn clojure (https://www.youtube.com/watch?v=zFPiPBIkAcQ at around 2:26). In the last example, you programme the game "Snake".

When looking at your question initially, I thought that your ...tests.snake namespace was just something you elided and not the actual namespace name. But given your repo, seems like it's the real namespace name that you're using.

That's invalid - you can't start a namespace with .. Rename it to tests.snake and the error will go away.

Unfortunately, your code in the repo still won't work because there are many other errors, but they should be easy for you to figure out on your own. And as a general advice - don't run your whole project by sending separate forms into REPL. Learn how to launch it with a single command - it'll induce good practices that will be useful even when using REPL.

QUESTION

Clojure: capture runtime value of function arg, to use in REPL

Asked 2021-Jan-08 at 15:32

Problem

My web front-end calls back-end queries with complex arguments. During development, to avoid time-consuming manual replication of those arguments, I want to capture their values in Vars, which can be used in REPL.

Research

This article shows that inline def is a suitable solution, but I couldn't make it work. After a call from the front-end happened, the Var remained unbound.

I launched the backend with REPL through VS Code + Calva, with the following code:

...

ANSWER

Answered 2021-Jan-08 at 15:32

The best way that I found is to use scope-capture library. It captures all the local variables with addition of 1 line in a function, and then with another 1-liner you can define all those variables as global, which allows you to evaluate in REPL any sub-expression in the function using runtime values.

If you ever spent a lot of time reproducing complex runtime values, I strongly recommend watching their 8-min demo.

My issue with inline-def was likely caused by reloading namespace after the Var was bound to a value. After restarting VS Code and carefully doing everything again, the issue went away.

QUESTION

How to avoid unresolved symbol with clj-kond when using hugSQL def-db-fns macro?

Asked 2020-May-11 at 10:58

I write Clojure using the VS Code Calva extension, which uses clj-kondo to perform static analysis of my code.

I'm using HugSQL to create Clojure functions from SQL queries and statements.

I'm aware that I could handle the database connection and the HugSQL integration with a library like conman, infact I used it in the past and I like it, but this time I wanted to keep things vanilla and talk to HugSQL myself.

HugSQL's def-db-fns macro takes a SQL file and creates Clojure functions based on the SQL queries and statements contained in that file.

My code below works, but clj-kondo complains that seed-mytable! is an unresolved symbol.

...

ANSWER

Answered 2020-May-11 at 10:58

From the clj-kondo documentation:

Sometimes vars are introduced by executing macros, e.g. when using HugSQL's def-db-fns. You can suppress warnings about these vars by using declare. Example:

QUESTION

Is it possible to get inline evaluation similar to Clojure in Ruby?

Asked 2020-Jan-15 at 00:51

In Clojure it's possible to evalute a form inline and get the result printed. The implementations vary for different editors, but here's how it looks like using Visual Studio Code with Calva:

Is it possible in any editor to do the same (or something similar) with Ruby?

...

ANSWER

Answered 2020-Jan-14 at 09:15

I suppose this feature is very common for functional languages (at least Elm, Haskell supports this, too) but I don't think it's possible in Ruby. But you can use REPL (eg. IRB or Pry) to get the return value of the statement you typed after pressing enter key.

If there is an IDE Extension that supports this feature I'm very eager to hear about it.
