L-Packer is a new Atari & Amiga executable compressor! Optimized for 64K-style demos, it balances high compression ratios with decent decompression speed. To sum up it stands right in the middle between Shrinkler and Cranker/UPX. Currently support both inflate & ZX0 algorithms. More technical details here: https://github.com/arnaud-carre/L-Packer
Testing & feedback are welcome!

Nice work
Thanks. Here is the mandatory thumb up!
Cool
Super!
Yep
Nice !
So I tested it for my 3 intros :
original shrinkler l-packer
Yes! 134248 60984 66968
The pixalated world 163220 64196 70524
Magical OCS 147596 61856 67808
It's a little over 64kb, but not by much, so it can probably be improved.
The problem is that the exe files no longer work: I get a crash while the cursor is flashing.
The three intros are in Amos, so they have a similar structure.
If you want, I can provide you with the uncompressed exe files.

Nice to have a new packer for Amiga. Tested with no particular problem here. I'm waiting for the no-flash option :)
nice one !

Yes, nothing could beat arithmetic coder of shrinkler (or STrinkler on atari). L-Packer is made when you can't afford too long depacking time with large exe such as 64KiB or more. So it's expected to be bigger than shrinkler, but should be smaller than any other amiga exe packers ( I hope :) )

Yes I know Amiga bootstrap is not fully compatible right now (doesn't work with C compiled stuff). Probably same issue with AMOS exe. I have to investigate that for future v1.0. Ok you can provide an uncompressed AMOS exe so I can have a look

I just added the option, please download again :)
Hey! This cruncher is great, but it would be even better if there was a Linux version (like there are Linux versions of Shrinkler and Cranker).
Just think about that, Leonard. :]

Definitely fills a - left empty for too long - space. Depacking time is very fast.

just updated to v0.92. Now Amiga version also supports depack-in-place
This sounds great - quick(er) depack time, good ratio, muli-algo, working in-place. Surely will test it with the next prod. Thank you for releasing it to public, respect!

if this prod is a fake, some info is false or the download link is broken,
do not post about it in the comments, it will get lost.
