Karsten Schmidt<a href="https://mastodon.thi.ng/tags/ReleaseWednesday" class="mention hashtag" rel="nofollow noopener" target="_blank">#ReleaseWednesday</a> — Extracted & extended the LISP-like DSL from an existing <a href="https://mastodon.thi.ng/tags/ThingUmbrella" class="mention hashtag" rel="nofollow noopener" target="_blank">#ThingUmbrella</a> example[1] as new small package for better/direct re-use in other projects:<a href="https://thi.ng/lispy" rel="nofollow noopener" translate="no" target="_blank">https://thi.ng/lispy</a>The core language is kept intentionally minimal, aimed at simple sandboxed data transformations/derivations, small code snippets/expressions in GUIs or config settings. However, the language is very easy to extend/customize with new functions or control flow constructs etc. Currently, the language is interpreted and has the following builtins (see screenshots). There's no macro support so far (and not sure if that's even desired here)...[1] The original <a href="https://mastodon.thi.ng/tags/HowToThing" class="mention hashtag" rel="nofollow noopener" target="_blank">#HowToThing</a> example browser REPL this was extracted from (and which has now been updated to use the new package):<a href="https://demo.thi.ng/umbrella/lispy-repl/" rel="nofollow noopener" translate="no" target="_blank">https://demo.thi.ng/umbrella/lispy-repl/</a> <a href="https://mastodon.thi.ng/tags/ThingUmbrella" class="mention hashtag" rel="nofollow noopener" target="_blank">#ThingUmbrella</a> <a href="https://mastodon.thi.ng/tags/Lisp" class="mention hashtag" rel="nofollow noopener" target="_blank">#Lisp</a> <a href="https://mastodon.thi.ng/tags/DSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#DSL</a> <a href="https://mastodon.thi.ng/tags/FunctionalProgramming" class="mention hashtag" rel="nofollow noopener" target="_blank">#FunctionalProgramming</a> <a href="https://mastodon.thi.ng/tags/REPL" class="mention hashtag" rel="nofollow noopener" target="_blank">#REPL</a>

Karsten Schmidt<a href="https://mastodon.thi.ng/tags/ReleaseWednesday" class="mention hashtag" rel="nofollow noopener" target="_blank">#ReleaseWednesday</a> 🚀 — I wonder how many other FLOSS devs are sitting on code for ~8 years prior to first release... In one of these cases (many others readily available in my stash 🙃), triggered by recent major updates to the thi.ng/vectors library, I've refactored (almost 100% rewritten) and applied the same approach to the new/old package:<a href="https://thi.ng/tensors" rel="nofollow noopener" translate="no" target="_blank">https://thi.ng/tensors</a>This package provides 1D/2D/3D/4D tensors, supporting different storage implementations (currently still all CPU side only) and an extensible set of polymorphic tensor operations (currently ~45 math ops, incl. matrix-matrix/matrix-vector products, reductions, argmin/max, activation functions etc.). The tensor classes themselves also provide several zero-copy slicing, re-ordering, clipping, extraction functions, most of them type-safe.The original (private) version was heavily reliant on dynamic code generation, which has now been replaced with higher-order functions to provide various dimension-optimized versions of all operations.This package is NOT specifically aimed at machine learning, even though it could probably used for some tasks in that realm (likely with extra hand holding). There are many other use cases for this kind of data structure...Also new in other packages in this release cycle (incl. some code examples):- <a href="https://docs.thi.ng/umbrella/arrays/functions/permutation.html" rel="nofollow noopener" translate="no" target="_blank">https://docs.thi.ng/umbrella/arrays/functions/permutation.html</a> - <a href="https://docs.thi.ng/umbrella/bidir-index/functions/decodeObjectIterator.html" rel="nofollow noopener" translate="no" target="_blank">https://docs.thi.ng/umbrella/bidir-index/functions/decodeObjectIterator.html</a> - <a href="https://docs.thi.ng/umbrella/transducers/functions/binned.html" rel="nofollow noopener" translate="no" target="_blank">https://docs.thi.ng/umbrella/transducers/functions/binned.html</a><a href="https://mastodon.thi.ng/tags/ThingUmbrella" class="mention hashtag" rel="nofollow noopener" target="_blank">#ThingUmbrella</a> <a href="https://mastodon.thi.ng/tags/TypeScript" class="mention hashtag" rel="nofollow noopener" target="_blank">#TypeScript</a> <a href="https://mastodon.thi.ng/tags/JavaScript" class="mention hashtag" rel="nofollow noopener" target="_blank">#JavaScript</a> <a href="https://mastodon.thi.ng/tags/Tensor" class="mention hashtag" rel="nofollow noopener" target="_blank">#Tensor</a> <a href="https://mastodon.thi.ng/tags/OpenSource" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenSource</a>

Karsten Schmidt<a href="https://mastodon.thi.ng/tags/ReleaseWednesday" class="mention hashtag" rel="nofollow noopener" target="_blank">#ReleaseWednesday</a> — I just released a new version (v8.0.0) of <a href="https://thi.ng/vectors" rel="nofollow noopener" translate="no" target="_blank">https://thi.ng/vectors</a>, an almost complete rewrite of the package with all of its ~900 vector operations. I've updated the Readme with a section of _potentially_ minor breaking changes, however I expect this to be a seamless upgrade for the vast majority of users...I've recently written more about the reasons and implications of this update and I'll refer you to those posts instead of repeating them once more (see links below).Just the top-level changes:- Replaced dynamic code generation with higher-order templating to be usable with strict content security policies (when deployed online) - New structure allows for vast majority of functions to have doc strings (and they do now) - More consistent/less confusing naming for some operations - Potentially improved tree-shaking and smaller project bundle sizesRelated to this update I've also refactored and fixed some bugs in other packages (e.g. color, geom, matrices). As a result both the color & matrix packages are now also free from dynamic codegen and therefore won't cause any problems with strict CSPsShould you run into any issues regarding this update, please get in touch (also grateful for any other experience/impact reports... 🙏)More info in these recent posts/threads:- <a href="https://mastodon.thi.ng/@toxi/114296442006935718" rel="nofollow noopener" translate="no" target="_blank">https://mastodon.thi.ng/@toxi/114296442006935718</a> - <a href="https://mastodon.thi.ng/@toxi/114319651778770391" rel="nofollow noopener" translate="no" target="_blank">https://mastodon.thi.ng/@toxi/114319651778770391</a> - <a href="https://mastodon.thi.ng/@toxi/114336012068839250" rel="nofollow noopener" translate="no" target="_blank">https://mastodon.thi.ng/@toxi/114336012068839250</a>Happy coding!<a href="https://mastodon.thi.ng/tags/ThingUmbrella" class="mention hashtag" rel="nofollow noopener" target="_blank">#ThingUmbrella</a> <a href="https://mastodon.thi.ng/tags/Vectors" class="mention hashtag" rel="nofollow noopener" target="_blank">#Vectors</a> <a href="https://mastodon.thi.ng/tags/TypeScript" class="mention hashtag" rel="nofollow noopener" target="_blank">#TypeScript</a> <a href="https://mastodon.thi.ng/tags/JavaScript" class="mention hashtag" rel="nofollow noopener" target="_blank">#JavaScript</a> <a href="https://mastodon.thi.ng/tags/OpenSource" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenSource</a>
