@alexarchambault thanks but I need to use scala 2.11 and hence I am stuck with older version , but is there no way to override this ?

So I am trying to run ammonite and I get the following

java.lang.UnsupportedClassVersionError: io/github/retronym/java9rtexport/Export has been compiled by a more recent version of the Java Runtime (class file version 57.0), this version of the Java Runtime only recognizes class file versions up to 55.0

I am using Ammonite repl 2.1.4 on JDK

openjdk 11.0.7 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10)
OpenJDK 64-Bit Server VM (build 11.0.7+10, mixed mode)

I will make an issue on this

Made issue here lihaoyi/Ammonite#1107

@yilinwei

@mdedetrich I've had that happen when I've been switching JDK's in my shell.

@sken77

is there a way to choose Scala version in ammonite 2.2?

I just updated it. but its pointing to Scala 2.13.3, and I want it to point to a 2.11

or some specifically what ammonite version supports 2.11

@sken77 I do some Scala teaching and often need to run examples against 2.12 and 2.13 in Ammonite, so I just pull amm-12 and am-13 releases directly from github and use them individually:

sh -c '(echo "#!/usr/bin/env sh" && curl -L https://github.com/lihaoyi/Ammonite/releases/download/2.1.4/2.12-2.1.4-7-d1e71b9) > /usr/local/bin/amm-12 && chmod +x /usr/local/bin/amm-12'

This doesn't help you directly, but I'm also not sure whether Ammonite is published for 2.11 anymore

^ this is based on looking at the releases page: https://github.com/lihaoyi/Ammonite/releases/

Anton Sviridov

@keynmol

1.6.7 seems to be the last one supporting 2.11: https://github.com/lihaoyi/Ammonite/releases/tag/1.6.7

@yilinwei I am not switching SDK's though? Can you be more specific?

In Ammonite shell and MacOS, is there a way to make the URL clickable?

I am doing the Scala println on a bunch of URLs, which I then copy paste into a browser. I wonder if I can make my printed URLs clickable

Oron Port

@soronpo

@abhishes_twitter I think this is a terminal issue and not an ammonite issue. The right terminal should give you clickable links no matter what the underlying printing program is.

For example, Intellij has a plugin that makes even file paths clickable, so that if you print a filepath, you click it and it opens it in IJ

Abhishek Srivastava

@abhishes_twitter

@soronpo makes sense. thanks for clarification.

yes I am using iterm and command + click makes it clickable thanks!

@yilinwei

@mdedetrich I just meant that when I had that problem it was because I had switched JDK's in the middle of my shell session and there were something cached which caused issues - I ended up nuking all the class files I could find and restarting everything.

I'm not sure that's your problem, just that I've seen the error message before.

Matthew de Detrich

@mdedetrich

Right, I didn't do any kind of switching though. What do you mean by nuking class files, i.e. did you delete ~/.ammonite?

Yilin Wei

@yilinwei

Yes

But I was frustrated at the time; there's probably a better way.

Matthew de Detrich

@mdedetrich

Hmm I already deleted ~/.ammonite

Matthew de Detrich

@mdedetrich

@yilinwei Anything else comes to mind? Ammonite is completely unusable in its current state

Let me reinstall jdk, although I don't see how this would do anything

Matthew de Detrich

@mdedetrich

Yup nothing

Yilin Wei

@yilinwei

@mdedetrich nope, how did you install ammonite?

Yilin Wei

@yilinwei

(you could upgrade your jdk I guess, bit that's obviously undesirable)

Matthew de Detrich

@mdedetrich

I am running JDK 11, thats like the latest stable?

@yilinwei I installed via ArchLinux's official package, i.e. https://www.archlinux.org/packages/community/any/ammonite/

I also made a bug on ArchLinux for the package, https://bugs.archlinux.org/task/67353

Yilin Wei

@yilinwei

Hmm, we have exactly the same setup (also on Java 11, and installed from the aur).

I'm on commit 223e5635fe7ce47a21b2f90835934b6e875ecdb9. Do you want to try that one?

The download URLs at ammonite.io using curl have an extra download in the path. https://github.com/lihaoyi/ammonite/releases/download/2.2.0/ @lihaoyi

@vmarquez

Does anyone know if there's a super easy way to save an ammonite history to a file and load later on? did I miss this in the docs somewhere? (RTFM is an acceptable answer to this question...) :)

implisci

@implisci

@vmarquez

def writeH(h:String) = os.write.over(os.pwd / h, repl.history.filter(!_.contains("write")). mkString("\n")) 
// removes lines with "write" as we don't want them to execute on reload 
val x = 1
val z = 3
writeH("foo")
exit
// Now load history back right into REPL
def loadH(h:String) = interp.load.module(os.Path(os.pwd + "/" + h)) 
loadH("foo")
x  + z == 4 // true

You can place writeH and loadH functions in ./ammonite/predef.sc at the bottom so they are always available

Opened an Infinite Loop with Ammonite Script Runner Issue with Futures. lihaoyi/Ammonite#1109

@mdedetrich

@yilinwei I just installed ammonite-git (r2382.56b4d41e-1) from AUR and I am getting

The file '/usr/bin/amm' is marked as an executable but could not be run by the operating system.

If you run from fish shell. Interestingly it works from a normal shell fine

But yes the latest ammonite from git appears to work, but it doesn't run in non bourne shells such as fish (which I think is a historic problem with ammonite)

Matthew de Detrich

@mdedetrich

However thats probably because the AUR package doesn't wrap the amm executable manually in a shebang (see https://aur.archlinux.org/packages/ammonite-git/#comment-757431)

@yilinwei So it seems to be fixed in the latest master however not sure if its fixed in the latest stable

Hi folks! What's the current blessed way to define initial predef-like code to execute when running Ammonite in sbt with test:run?

Trying to start Ammonite:

java.lang.Exception: Failed to resolve ivy dependencies:Error downloading com.lihaoyi:ammonite-shell_2.13.1:2.0.4-6-ef64cbe

Looks like I need to reinstall. Was this caused by the removal of a dependent jar?

@sken77

is there a way to get commands like pwd or ls to work on intellij
