holgerbrandl: I, for one, welcome our kscript overlords! All we need is `apt-get kscript` supported (and `brew install kscript` of course)

<@U2E974ELT> Never thought about it, but it’s a good idea and I’ll look into [it](<https://github.com/holgerbrandl/kscript/issues/25>). Though. the current [installation](<https://github.com/holgerbrandl/kscript#installation>) using `curl -Lso ~/bin/kscript <https://git.io/v9R73> &amp;&amp; chmod u+x ~/bin/kscript` seems pretty straightforward already.

curl from random url + chmod+x? Asking for a trouble…

I dunno, is it possible to launch a daemon JVM process like gradle or something, so that JVM is always ready for a script? It can die automatically in few minutes of inactivity, recycle periodically to avoid memory leaks, etc.

there are frameworks like nailgun (<http://martiansoftware.com/nailgun/>) to do so, but in the end it’s just 300ms for the jvm warmup, so I have not looked into it yet.

You can use AppCDS as well (as it's for local development purposes) which can speed startup quite a bit

300ms in a bash script processing thousands of files might add up to smth

maybe write a bash replacement :slightly_smiling_face: btw holger, your /start/,/stop/ example does not appear to match the kotlin example, and in your line numbering example, the kotlin can be shorter using string interpolation.

FYI here's Scala equivalent, for inspiration:  <https://github.com/lihaoyi/Ammonite>

<@U0BDMQTHS> thanks for your suggestions. I’ve corrected them.

<@U0B8ZP13Q> I’ve worked with ammonite for a while, but somehow never embraced it enough to use it as an actual bash replacement. It was/is useful for scala-prototyping. I wish the kotlin REPL (which could serve the same prototyping purpose) would be half as stable as ammonite, but somehow it’s (imho) progressing just slowly.
