@katox merged, thanks
borkdude 2021-03-03T12:02:12.054700Z
now for your babashka compilation problem: have you solved this too?
katox 2021-03-03T12:02:31.055100Z
no, let's move to a proper forum .)
borkdude 2021-03-03T12:04:39.055300Z
we can do in private.
katox 2021-03-03T12:17:33.055900Z
for the record, the error was cloning the repo without --recursive, thanks!

I think all the ingredients for an all native deps.edn / tools.deps CLI are there now: https://github.com/borkdude/tools-deps-native-experiment/tree/shell#shell-branch This + deps.clj = no JVM for dep resolution / downloading, just JVM for REPL / running of apps / bytecode AOT compilation
borkdude 2021-03-03T16:36:36.057300Z
Will wait a bit for the shell approach to appear properly in tools.deps.alpha.
borkdude 2021-03-03T16:38:59.058500Z
What do we win with this? Maybe a bit questionable to go through these hoops, but: - startup time for downloading deps - running this is about as fast with caching of the CLI as it is without, if the deps are already there - could be used in babashka to decouple downloading of scripting deps from a JVM
ghadi 2021-03-03T16:53:23.059Z
what percentage of execution time is startup vs. downloading deps?
borkdude 2021-03-03T16:53:49.059200Z
it depends on how many deps you have
borkdude 2021-03-03T16:53:58.059400Z
and how fast your network is
alexmiller 2021-03-03T16:54:23.059600Z
and how much is in your cache :)
borkdude 2021-03-03T16:54:34.059900Z
I will do a small test locally with only medley
borkdude 2021-03-03T16:57:43.060100Z
300ms vs 3000ms
borkdude 2021-03-03T16:57:54.060400Z
(with medley and .cpcache removed from local caches)
borkdude 2021-03-03T17:00:23.061600Z
The comparison wasn't entirely fair because I ran clojure in my tools-deps-native project which had more deps so calculating the classpath would take more time. Better comparison:

Update regarding tools-deps-native. The GraalVM problems have now vanished due to getting rid of Jsch.
borkdude 2021-03-03T23:12:20.062800Z
The startup time + downloading medley with clojure at 1.10.2.801 (which doesn't use JSch anymore) also seems to have improved a little, now down to 2s compared to 2.5s above
