It's pretty smooth on Amiga 500+Wicher 508i's 68000 from 25Mhz to 50Mhz. I run BitplaneBG sample demo on Amos Pro 2.0.

Thank you, guys!

Last week I analyzed the code produced by the AMOS Professional Compiler and changed the ALS code in order to have the compiler output the most efficient code it is capable of. Contextually, I have also added a new little feature (palette segments), updated two demos and improved the documentation constantly.
This week I'm continuing the review of the documentation and constantly improving it. Once done, (hopefully) it will only be a matter of preparing a web page before ALS gets released.

VIDEO PREVIEW #5

Since last time, I improved/fixed a few things, revised greatly the documentation and updated the programs shown in the video. I also prepared the project web page: https://www.retream.com/ALS (redirects to https://retream.itch.io/als).
Currently I'm continuing to revise the documentation iteratively: when no more corrections are needed, ALS will be released - and I hope to make that happen this week.

@saimo

demo is pretty cool...

just for understanding... you use AGA for it (256 colors)?

How does it integrate with "standard AMOS" commands?

For example regarding sprite or bob handling? Normally all AMOS commands do not support AGA

ALS adapts to the chipset of the machine it runs on. If it finds AGA, it can do more.
The "ghosts" demo (the first demo in the latest video) runs on OCS/ECS.

The answer is in the description
"ALS" stands for "AMOS Layers System" (formerly "MLS" = "Multi-Layer System"), as it turns the screens of AMOS Professional ("AMOS" from now on) into layers that can be laid over one another, with complete control of order, colors and trasparency, while keeping them renderable as usual.
It is easy to use, does not require much knowledge of the Amiga graphics hardware, does not require installation or extensions, and comes as a set variables, arrays and procedures written in fully-commented AMOS code - it can be thought of as an AMOS source-level library.

It took longer than I thought, but finally ALS is out!
Get it for free from https://www.retream.com/ALS.
I hope that it will be useful to somebody, and that some day I'll get to see a cool game made with it ;)

I have released a minor bugfix update for ALS which fixes a few minor issues.

v1.89 (21.03.2021)
* Fixed bug in ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE_SEGMENT[], which caused the low 12 bits of the colors to be set to the same value as the high 12 bits (because the instruction Areg(0)=PSA was placed just after the beginning of a loop, despite the comment just above said: "Areg(0) is set only once before the loop thanks to the fact that it is updated by Call with the value returned by ALS_SETCOLORXXRANGE()").
* Replaced all End/Pop Proc[False] with End/Pop Proc[0], as False might crash the Compiler in some circumstances.
* Fixed a comment in the ALS code.
* Fixed the metadata of a couple of ILBM files.
* Added a note to the demo3 program.

Working on Follix (which uses ALS) inspired a few improvements.

v1.94 (06.06.2021)
* Added ALS_CHECK_LAYER_INDEX[].
* Added ALS_COPY_PALETTE_SEGMENT[].
* Added ALS_CREATE_LAYER_AS_CLONE[].
* Added ALS_SET_LAYER_A_AND_COLORS_FROM LAYER[].
* Made check on layer index in ALS_DESTROY_LAYER[] and ALS_MAKE_LAYER_DESCRIPTOR[] more robust.
* Removed check on layer index from ALS_GET_LAYER_DEPTH[].
* Simplified ALS_OPEN_FILE[].
* Updated manual.

Just released another update.

v1.95 (4.7.2021)
* Optimized ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE[] and ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE_RANGE[] a little bit.
* Removed wrong comment from ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE[].

https://www.retream.com/ALS

This is the last version that supports also OCS and ECS. ALS v2 will be AGA-only. The reason is that supporting all the chipsets requires lots of additional code and also slows down execution in many places, while functionality is still very limited on OCS and ECS due to the fact that they offer only 6 bitplanes and 32 color registers. ALS is much more useful on AGA, so it makes sense to have a leaner and faster version for that chipset.

Also, I decided to postpone the release of Follix to after ALS v2 is done, so that the game can benefit from it.

v1.96 and v2.0 released

As announced recently, here is ALS v2, whose main difference with the previous versions is that it's for AGA only and, therefore, can benefit from faster and smaller code (the compiled binary is about 3.5 kB smaller).
Besides the work done for the AGA-only transition, there are also a few more improvements, many of which made it also to a new v1 library (v1 is supposed to be end-of-line, but still I couldn't resist fixing/improving what surfaced along way). The changelogs below detail the changes.

https://www.retream.com/ALS

v2.0 (6.7.2021)
* Removed useless code from ALS_COPY_PALETTE_SEGMENT[].
* Removed OCS/ECS code.
* Removed OCS/ECS palettes support.
* Removed ALS_CHIPSETID, ALS_MAXLAYERCOLORSNUMBER, ALS_MAXPLANESNUMBER, ALS_PALETTECOLORSNUMBER, ALS_ADDRESSABLECOLORSNUMBER.
* Optimized code for AGA.
* Optimized ALS_SET_DISPLAY_COLORS_FROM_PALETTE[], ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE[] and ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE_SEGMENT[] a lot.
* Added ALS_BUILD_DISPLAY_COPPERLIST_HEAD[] and ALS_BUILD_DISPLAY_COPPERLIST_TAIL[].
* Made various other improvements.
* Revised/extended manual.

v1.96 (6.7.2021)
* Removed useless code from ALS_COPY_PALETTE_SEGMENT[].
* Optimized ALS_SET_DISPLAY_COLORS_FROM_PALETTE[] a little bit.
* Added ALS_BUILD_DISPLAY_COPPERLIST_HEAD[] and ALS_BUILD_DISPLAY_COPPERLIST_TAIL[].
* Made various other improvements.
* Revised/extended manual.

I have tested both version extensively through their test/demo programs and by means of ArtPazz and Follix. All tests have been done on a real Amiga 1200 (with and without accelerator board) and in UAE, and ran both from interpreter and as compiled programs. No issues were found, so it looks like the massive work didn't break anything.

@all

Just released an update aimed at improving the terminology and the documentation.

v1.97 & v2.1 (16.7.2021)
* Renamed "palette segments" as "segments".
* Renamed: ALS_COPY_PALETTE_RANGE[] as ALS_COPY_SEGMENT_FROM_PALETTE_RANGE[]; ALS_EXTRACT_PALETTE_SEGMENT[] as ALS_CREATE_SEGMENT_FROM_PALETTE_RANGE[]; ALS_SET_DISPLAY_COLORS_RANGE_FROM_PALETTE_SEGMENT as ALS_SET_DISPLAY_COLORS_RANGE_FROM_SEGMENT[].
* Updated/revised in-code documentation.
* Updated/revised/fixed manual.

https://www.retream.com/ALS

A quick heads-up to let you know that I released a couple of littles updates.

v1.99 and v2.3 (20.2.2023)
* Changed the conditions of many If, Until and While statements and turned For ... Next loops into Repeat ... Until loops to have the AMOS Professional Compiler produce shorter and faster code.

v1.98 and v2.2 (19.2.2023)
* Added CPU caches clearing after machine code routines generation in ALS_INITIALIZE_SYSTEM[].
