I couldn't find much documentation about SLLs. It is hard to know
exactly what SLLs supported and how they used to work. I believe SLL
loading was part of the VM, not the image. If so, I don't know if,
for example, they could handle class reshaping at all.<br>
<br>
DynamicCuisLibraries are fully implemented in Smalltalk. One
advanced feature is that if the image that builds a DCL has a
different shape for some class as the image that loads it, the load
procedure computes the union of the instance variables known by
each, and adjust any ivar access in CompiledMethods so everyting
works as expected. I believe that neither SLLs nor Parcels could do
this.<br>
<br>
Please take a look at the included tests.<br>

<br>
This year I've been busy, with the help of Felipe Zak, on
implementing <br>
two new features for Cuis.<br>
<br>
1) Bootstrap. A package that lets us bootstrap new Cuis
images, <br>
including only what is desired. Smallest so far is about
150Kb, and <br>
includes Stdout, Collections, Magnitudes, etc.<br>
<br>
2) CuisDynamicLibraries. These are files that include compiled
Cuis <br>
code. They are somewhat similar to .so and .dll. They are much
(MUCH!) <br>
faster to load than .<a href="http://pck.st" rel="noreferrer" target="_blank">pck.st</a>,
and don't require a Compiler to be present.<br>
<br>
These together allow for an image of less than 200kb that can
load any <br>
needed additional code via .dcl files.<br>
<br>
Felipe and I will be giving talks on these new features at the
FAST <br>
Smalltalks 2023 conference at Universidad de Quilmes.
Documentation is <br>
on its way, but if you are brave enough, comments and examples
included <br>
in code could suffice.<br>
<br>
Cheers,<br>
<br>
