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 🙏

Readme

@tabnas/alchemy-cli

The alchemy command for alchemy, the small transformation language for streaming structured data through the tabnas parser and transducer stack.

npm install -g @tabnas/alchemy-cli
alchemy canon FILE       print the program in canonical form
alchemy format FILE      print the program in layout form
alchemy check FILE       parse, desugar, resolve, check and build the plan
alchemy explain FILE     print the plan report
alchemy run [--render csv|json] [--no-native] [--max-output-bytes N] PROGRAM INPUT
                         run the program over the JSON document INPUT
alchemy translate --from FORMAT --to FORMAT [--path PATH] [--key KEY]
                  [--with PROGRAM] [--max-output-bytes N] INPUT
                         write INPUT, read as FORMAT, in another format
alchemy formats          print the formats translate reads and writes, as JSON

A FILE, PROGRAM or INPUT may be - for standard input. A failure is one JSON object on standard error, and the exit status follows its code; src/cli.ts documents both.

The command composes @tabnas/alchemy with the stages it compiles onto: @tabnas/transduce's routers and @tabnas/render's renderers, passed to alchemy's compile, and run reads INPUT with @tabnas/json. translate reads and writes the formats of the grammar packages it carries (@tabnas/abnf, c, chess, css, csv, ebnf, expr, feed, gbnf, ini, json, json5, jsonc, jsonic, jsonl, markdown, proto, semver, toml, xml, yaml and zon), composing each pair's route from the translation parts the packages export with alchemy's translate; src/translate.ts documents it.

This package includes its TypeScript sources under src/ alongside the compiled JavaScript and declarations under dist/.
