Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

The io-lionweb-mps-specific package

license CI npm

This NPM package contains an implementation of the io.lionweb.mps.specific language. The MPS implementation of that language is part of the lionweb-mps plug-in. The annotations in this language are used to export MPS-specific language (structure) metadata as part of LionWeb language exports from MPS (in the LionCore M3 format). More specifically, this pertains to metadata like the alias, short description, documentation, etc., of a language concept.

It can be added to a TypeScript codebase as follows:

$ npm add @lionweb/io-lionweb-mps-specific

API

The API consists of the following things exported from this package:

  • The implementation of the language consists of the following classes: ConceptDescription, Deprecated, KeyedDescription, ShortDescription, VirtualPackage. Also see this PlantUml diagram for some more information.
  • The language is defined through the constant ioLionWebMpsSpecificLanguage (of type Language). Its classifiers are exported separately through the ioLionWebMpsSpecificClassifiers dictionary.
  • The deserializeLanguagesWithIoLionWebMpsSpecific function deserializes a LionWeb serialization chunk as an array of Languages, potentially being annotated with instances of annotations from the io.lionweb.mps.specific language.
  • The ioLionWebMpsSpecificAnnotationsFrom function returns the (instances of the) io.lionweb.mps.specific language's annotations that annotate the given language element (of type M3Concept).
  • The textualizationOfAnnotationsIn function renders a textualization of all instances of io.lionweb.mps.specific annotations, in the given languages' tree structure. Note: only language elements having annotations (at any nesting depth) are rendered. This is useful to get a quick overview of the annotations.

LionWeb version

The implementation is explicitly tied to LionWeb version 2023.1, meaning that its definition refers to the LionCore and LionCore builtins languages in that version. No parametrization in the LionWeb version is provided at the moment.
