Clojurians Log v2

What does upgrade false do? I don't see it in the sample project.clj for lein that documents most options. It looks like maybe it is an option for the lein-ancient plugin, antq which I guess is what you would use to replace lein-ancient has https://github.com/liquidz/antq/blob/main/doc/exclusions.adoc

@alexmiller ?

Tools invoked by invoke-tool use the https://clojure.org/reference/clojure_cli#function_protocol - note the key :clojure.exec/out there. the envelope itself is what is returned on stdout in this mode (which may optionally include :out)

so I think you want:

((requiring-resolve 'clojure.tools.deps.interop/invoke-tool)
   {:debug true :preserve-envelope true
    :tool-name "antq" :fn 'outdated :args {:reporter "edn", :clojure.exec/out :capture}})

oh, the docs are wrong in that link!

Well, that works for the simple case (`build/hello`):

user=> (invoke-tool {:debug true :preserve-envelope true :tool-alias :build :fn 'hello :args {:name "edn" :clojure.exec/out :capture}})
args [hello {:name edn, :clojure.exec/out :capture, :clojure.exec/invoke :fn}]
Invoking:  clojure -T:build -
{:tag :ret, :val "nil", :ms 0, :out "Hello, edn!\n"}

user=> (invoke-tool {:debug true :preserve-envelope true :tool-name "antq" :fn 'outdated :args {:clojure.exec/out :capture}})
args [outdated #:clojure.exec{:out :capture, :invoke :fn}]
Invoking:  clojure -Tantq -
Execution error (ExceptionInfo) at clojure.tools.deps.interop/invoke-tool (interop.clj:83).

Yeah, I don’t know what’s happening there

(at least that explains why :clojure.exec/invoke is appearing -- but it is passed :fn instead of true?)

yeah

antq exits with System/exit -- would that affect how invoke-tool behaves?

if it wasn't done printing to stdout, then maybe

For -X (or -T invocation), it really shouldn't call System/exit anyway. I'll open a ticket there...

yeah, it has to be that the envelope is not on the stream so it just doesn't know what happened

https://github.com/liquidz/antq/issues/261

Looking at the source https://github.com/clojure/clojure/blob/master/src/clj/clojure/tools/deps/interop.clj#L74-L86 I would expect if-let [envelope (edn/read-string (slurp out))] to take the truthy path and return the envelope (since I have :preserve-envelope true).

I guess this is why:

(~/clojure)-(!2046)-> clj
Clojure 1.12.0
user=> ((requiring-resolve 'clojure.tools.deps.interop/invoke-tool)
   {:debug true :preserve-envelope true
    :tool-alias :build :fn 'hello :args {:reporter "edn"}})
args [hello {:reporter edn, :clojure.exec/invoke :fn}]
Invoking:  clojure -T:build -
{:tag :ret, :val "nil", :ms 0}
user=>
(~/clojure)-(!2047)-> clojure -T:build hello '{:reporter "edn"}'
Hello, World!

(`build/hello` just has (println "Hello, World!") in it)

As a follow-up to this, it was due to antq calling System/exit in -X/`-T` mode and that has now been fixed, and I can run tool as expected with invoke-tool now.

Does that git repo have deps.edn or pom.xml? It needs one of those to be used as a git dep.

If it doesn't have either of those, you can use the :deps/manifest option to treat it as if it has an empty deps.edn file -- https://clojure.org/reference/deps_edn#deps_deps_manifest -- but you'll need to specify any project dependencies yourself, explicitly.

Ah, I didn't think about that. It only has project.clj. Thanks!
