How can I get the name of the currently running script file in ammonite?

[jk-1]

In bash I can get the script file name from argument $0

Script in file /home/jk/bin/exp01.sh:

#!/bin/bash

echo '$(pwd)'
echo $(pwd)
echo '$@'
echo $@
echo '$0'
echo $0
echo '$0 $1 $2 $3 $4 $5'
echo $0 $1 $2 $3 $4 $5

Output:

jk@tmi:~/tmp$ exp01.sh 1 2 3
$(pwd)
/home/jk/tmp
$@
1 2 3
$0
/home/jk/bin/exp01.sh
$0 $1 $2 $3 $4 $5
/home/jk/bin/exp01.sh 1 2 3

So how can I get the $0 /home/jk/bin/exp01.sh in ammonite script?

I tried following simple /home/jk/bin/exp02.sc:

#!/usr/bin/env /usr/local/bin/amm

import $ivy.`com.lihaoyi::mainargs:0.3.0`
import $ivy.`com.lihaoyi::sourcecode:0.3.0`

println(s"pwd: ${os.pwd}")

println(s"FileName: ${sourcecode.FileName()}")
println(s"FullName: ${sourcecode.FullName()}")

@main
def entrypoint(args: String*) = {
  println(s"entrypoint FileName: ${sourcecode.FileName()}")
  println(s"entrypoint FullName: ${sourcecode.FullName()}")
  println(s"entrypoint args: ${args.toSeq.mkString(" ")}")
}

Output is:

jk@tmi:~/tmp$ exp02.sc 1 2 3
pwd: /home/jk/tmp
FileName: exp02.sc
FullName: ammonite.$file.$up.bin.exp02.res_5
entrypoint FileName: exp02.sc
entrypoint FullName: ammonite.$file.$up.bin.exp02.entrypoint
entrypoint args: 1 2 3

FileName is missing the absolute path and FullName needs additional parsing before it can be used as path.

What is the most elegant way to get the script file absolute name? If there are none, could this be a further development issue?

Sounds like you want implicitly[sourcecode.File] I think
