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 🙏

Gramática de Tcode para tree-sitter

Readme

tree-sitter-tcode

Gramática de tree-sitter para Tcode. Es un espejo del parser del compilador (ejemplos/lexer/lib/sintaxis.t): las reglas y los nombres de nodo son los que el compilador ya usa (nombre_de_clase).

Generar y probar

npm install                 # trae tree-sitter-cli
npx tree-sitter generate    # src/parser.c desde grammar.js
npx tree-sitter test        # el corpus en test/corpus/

Probar contra el compilador real

npx tree-sitter parse ../../ejemplos/compilador/tcodec.t

Todo el compilador, el lexer, std/ y programas/ parsean sin errores ni nodos MISSING.

Qué hay

  • grammar.js — la gramática (el DSL de tree-sitter).
  • queries/highlights.scm — resaltado de sintaxis.
  • test/corpus/ — casos de prueba con su árbol esperado.
  • src/ — el parser C generado, listo para consumir.

Limitaciones conocidas

  • como y bloque son palabras de contexto en Tcode (el lexer las trata como identificadores); aquí se lexan como palabras clave, así que un programa que las use como nombre de variable se resaltará raro. Es un caso poco común.
  • El bloque<T> de los tipos es indistinguible de un genérico Par<A, B>: ambos son ident <...>. Se resuelve igual que en el compilador.
