@Shokodemon
wish it did that. i understand why lihao moved away from sbt
i managed 1.0.0, unified global version file ftw
pushing 1.6.6
and that broke akka. :D

I'm translating a bash script to ammonite, so I'd like to be able to run a lot of commands while suppressing their output. I thought I would use a construction like this:

import sys.process._
val devNull = ProcessLogger( _ => (), _ => ())
"ls" ! devNull

But when I try to run a script with just those lines, it hangs during compilation. The same lines run just fine in the REPL

Is there a reason this doesn't work? Am I doing something dumb?

@Baccata

@wilt-rally not too sure what you're doing wrong there, but I highly recommend using the following library (developed by the maintainer of ammonite) to deal with files / subprocesses :

Hi, is it possible to choose the Scala version used for running a standalone ammonite-repl?
or is it just the standard scala binary from $PATH?

Recently, i really wish it were possible to do something like sudo myFun where myFun is an arbitrary JVM function from within my Scala code. But I suppose that would be impossible under the linux security model as it currently stands.
Olivier Mélois
@Baccata
@kubukoz ammonite launchers are released for both 2.12 and 2.13. If you look closely at the one-liner install script, you can see the version appearing in the github URL : http://ammonite.io/#Ammonite-REPL.

Anton Kulaga
@antonkulaga
I see that GraalVM allows building native images. Has anybody tried to build native immage of ammonite?
Jakub Kozłowski
@kubukoz
nice @baccata, thanks
although the homebrew version installs 2.12
Olivier Mélois
@Baccata
@antonkulaga I don't think that'd be possible, on the account on ammonite relying on some JVM reflection features, which Graal can't translate to native
@kubukoz uninstall ammonite from brew, install it via the one-liner, problem solved :D
Jakub Kozłowski
@kubukoz
yeah, thanks

@Shokodemon
does ammonite still phone home ?

@lihaoyi Just saw lihaoyi/Ammonite#984 (which I guess ought not to slow down things compared to before the addition of --thin)
Just so you know, I tend to run Ammonite via other kinds of coursier bootstraps (without jars-in-jars), lightweight ones that rely on the coursier cache. These don't incur perf penalties, and are actually faster than assemblies (I described how I benchmark things, with benchmark results, in this notebook).
These could be used instead of the assemblies that are pushed to github.
Li Haoyi
@lihaoyi
sounds good, i think as a default just sticking with dumb assemblies might be the best thing for now, just to fix the regression
after the fix, we can then consider fancy additional stuff separately :)
There is some understandability downside going from bog-standard-classloader-isolation, 1995-style, to a new bootstrap/isolation mechanism.
Alexandre Archambault
@alexarchambault
Yeah I agree on that :|
I intend to document them in more detail soon(ish), along with the new install command of coursier.
Li Haoyi
@lihaoyi
when you use Ammonite yourself, e.g. for embedding into almond, that's a sufficiently specialized use case I think it's ok if you end up bundling it yourself (e.g. shading all the non-api classfiles)
Alexandre Archambault
@alexarchambault
I don't shade stuff in almond, I rely on the lightweight coursier bootstraps (that rely on the coursier cache instead of embedded jars in jars).

@lihaoyi I just used Ammonite + ujson + upickle + requests to rehydrate an elasticsearch index that got destroyed, from unparsed event data stored in a remote cassandra cluster. Took 1 hour all in all, with no previous experience of requests or ujson. I just wanted to say thank you!
I'm already a patreon but I should probably prod my bosses and ask them to add some themselves.

Has ammonite dropped support for the 2.11 series ? 1.6.9 doesn't seem to have been published for those
(not that I care about having support, but I'm updating mill with ammonite 1.6.9 and some tests are failing because the repl artifact is missing for 2.11)
Li Haoyi
@lihaoyi
yes
I support two major versions :)
feel free to bump whatever failing mill tests to 2.12

is there any way i could preprocess the strings and get rid of those characters?

Bassel
@Shokodemon
i realized i can circumvent the errors using lines.map(line => (printf("s", line))
Li Haoyi
@lihaoyi
easiest would be to just println them yourself
you could also customize repl.pprinter to not try to be clever with strings, but that's more work (not that much more tho)
Andrew Richards
@ajrnz

Does the ammonite/mill's import $ivysyntax have anything equivalent to sbts classpathTypes which lets you import extra types of artifacts (just just jar/source etc)?
I am unable to use:

import $ivy.`org.vafer:jdeb:1.7`

because it declares its artifact to be type maven-plugin (not jar) and is ignored by coursier.

In sbt you can fix this with:

classpathTypes += "maven-plugin"

Any workaround?

Olivier Mélois
@Baccata
@ajrnz if you manage to download the artifact "manually" (there might be an option in the coursier API, otherwise you'll have to build the http request by hand), then you can call upon the interp api to load stuff into the classpath. That artifact is then taken into account for the compilation of the next stage of your script (or the downstream scripts) : http://ammonite.io/#Multi-stageScripts
Andrew Richards
@ajrnz

@Baccata Yeah that works. Not pretty though:

coursier fetch org.vafer:jdeb:1.7

and then

import $ivy.`org.vafer:jdeb:1.7`
interp.load.cp(Seq(os.Path(coursier.cache.CacheDefaults.location + "/https/repo1.maven.org/maven2/org/vafer/jdeb/1.7/jdeb-1.7.jar")))
@

It not obvious how/where you would insert this into the ammonite code
