Is it possible to combine multiple R aliases into one alias?

How do you mean?

Say alias A says extra deps d1 d2, alias B says extra deps d3 d4, now I want to make an alias AB which combines A and B so it has extra deps d1 .. d4

Basically wondering if I could do something like https://github.com/borkdude/boot-bundle using deps.edn

@borkdude there's no inheritance. So the only way to do it is by modifying the edn file. I've been writing https://github.com/SevereOverfl0w/ednup with the goal of it eventually supporting this.

Say, I'm trying to figure out how to effectively deal with the .cpcache directory in circleci. The way it works is that circleci can store a directory in a cache which is then available to subsequent steps (although the subsequent steps might themselves run on different VM instances).

So what I currently do is run clojure -A:foo:bar -Spath to download a bunch of stuff and then cache the .m2 and .cpcache directories

My question is, will tools.deps create a single .cpcache entry for the combined :foo:bar aliases, or will it create a :foo cache and a :bar cache? (Or all three?)

I'm wondering if it would be more efficient to run clojure -A:foo -Spath; clojure -A:bar -Spath

combined

the cache key is based on the set of aliases used

Aha, makes sense. Thanks @alexmiller

Hey, I'm migrating some lein project to deps.edn and somehow it looks like my dev/user.clj isn't loaded in the repl, even though I use clj -R:dev and the :dev alias does have :extra-paths ["dev" "fixtures"]. My user.clj is very simple:

(:require
   [com.stuartsierra.component.user-helpers :refer [dev go reset]]))

$ clj -R:dev dev/user.clj
$

$ clj -R:dev
Clojure 1.9.0
user=> (dev)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: dev in this context, compiling:(NO_SOURCE_PATH:1:1) 
user=> 

use -A not -R

question about CI and .m2 - is there anything I have to do to set Clojure CLI on a machine for being able to cache artifacts in .m2?

this machine does not seem to have Maven, do I need it? or .m2/settings.xml

nope

if you are ci'ing inside some kind of container you might want to set things up so ~/.m2 is stored in a way that persists across different runs

is .m2 created for me?

yes

tools.deps will store git deps in ~/.gitlibs too

ok thanks, my CI executes things in a weird way I think...every call to clojure resets .m2 so it downloads everything again, investigating...

yeah, you are likely building in some kind of container environment with nothing persisted between builds

I am on Azure Pipeline..

yeah..

in theory that should be fine, m2 is a cache, so if the cache is missing it will just rebuild it, but it is much better to persist m2

you actually might be running in to another caching issue too

yeah I see it is redownloading the whole thing

the clj tool fetches deps and builds the classpath once and sort of caches that, if the deps it fetches go missing, but the cache file it generates is still there, it will blow up

makes sense yeah

thank you so much

which command creates .m2? I know first execution does, but I would like to see it there before running my actual other tasks

can I just do clojure -Sdescribe?

actually let me try locally

yep that works

$ mv .m2 .m2-backup
$ clojure -Sdescribe

it is downloading alpha6 by default

No, it’s not - that’s an artifact of your deps.edn files

By default, clj will use 1.9.0 based on the ~/.clojure/deps.edn

right

I should have use -Srepo maybe?

another question I have is if I can have aliases in parent dir and consume in children dir, in a monorepo setup for instance

I tried with CLJ_CONFIG to the root but I don't see it working...

oh now I see it working cool
