Is anyone aware of a tools-deps dependency visualizer? (i.e. the equivalent of https://github.com/walmartlabs/vizdeps)

Nevermind! It turned out to be relatively easy to write my own 🙂

A little rusty with Clojure on JVM...if I want to work against a Java code base, do I need to include taarget in order to import classes in the REPL using clojure?

yes, assuming target is the root of your compiled classes

ok cool that's what I was missing then, I guess it goes without saying that I then need to compile the java code every time the file changes

thank you Alex that works

Hello, what do people use to watch for file changes to trigger actions (e.g. clojure.core/compile)? Lein certainly has a watch functionality/plugin but what about clj CLI? Thanks!

as above, clj doesn't cover compilation

it does cover "running programs"

the compiler is a program

watching is a program

compose programs, run with clj if you like

thank you, Alex. My question is essentially: Does anyone made a clj-friendly plugin for watching files and executing actions upon change?

I'm not aware of something specific to tools.deps, but there several watcher type things out there

last time I needed one, I just wrote the 60 lines of java interop to use the one in the jdk

admittedly, it's a weird java api

https://www.clojure-toolbox.com/ has a bunch of filesystem watcher libs

@holyjak I use (load "core") to load/reload files But usually it's a "built-in" feature from your IDE/Plugin/Editor/..

Wied problem: while this works

clj -J-javaagent:bin/springloaded-1.2.5.RELEASE.jar -J-noverify

; deps.edn: [...]
:aliases {:agent {:jvm-opts ["-J-javaagent:bin/springloaded-1.2.5.RELEASE.jar" "-J-noverify"]}}
; CLI:
$ clj -O:agent
Unrecognized option: -J-javaagent:bin/springloaded-1.2.5.RELEASE.jar

-J passes options through. They don't start with -J inside :jvm-opts

You want

:aliases {:agent {:jvm-opts ["-javaagent:bin/springloaded-1.2.5.RELEASE.jar" "-noverify"]}}

oh I see, please ignore 🙂 I have to omit -J

Given a .clj file path, what is the simples way of finding out the namespace of the file? I could read the first line and check for #"\(ns (\w+)" but there is surely a cleaner way?

There's no guaranteed way because you can change namespaces inside a file and you can load arbitrary source files into another namespace.

The convention is path/to_the/file.clj => path.to-the.file tho' -- note the _ to - mapping. And you'll need to know what it is _relative to your classpath_ because if src/main is on your classpath, src/main/path/to_the/file.clj is what will get loaded if you try to require path.to-the.file

tools.namespace is a lib for doing this kind of thing
