Show HN: Dak – a Lisp-like language that transpiles to JavaScript
Hi HN, author here. Happy to answer any questions.<p>I had an itch to make a lisp like language that was a thin layer on top JavaScript. Something that could leverage the thriving ecosystem that exists around JavaScript. It's brittle, hot off the oven.<p>Besides being a fan of parenthesis, I think macros fill in a gap that the JavaScript ecosystem today fills in with one-off compilers, bundler plugins and such. Macros can't do everything, but for example I think they have the potential to enable things like JSX, Solid and Svelte style libraries.<p>Take the tour to get a feel for what it can do and play with the live code in your browser!
Show HN: Tabular – Email design tool that generates bulletproof email HTML
Hi HN,<p>I’ve developed <a href="http://tabular.email" rel="nofollow">http://tabular.email</a> (Tabular), a new email design tool that generates hybrid mobile-first email HTML. Think of emails for your app, such as user verification or welcome, newsletters, or marketing emails.<p>My goal was to make designing emails as quick and intuitive as possible. To make a tool where everything is done visually (adjusting margins, paddings, gaps, dimensions etc.), without the user having to worry about writing email HTML code.<p>Cool thing is that you get full control over how your email looks on mobile devices. When designing, you can switch to mobile mode, and any styling changes that you make will overwrite how it looks on desktop.<p>Tabular’s algorithm generates responsive HTML code that renders on all major email inboxes and devices, including older desktop Outlooks (e.g. Outlook 2010, 2013 etc.). At the moment, I’ve implemented 8 integrations so you can connect your email service provider (e.g. Sendgrid, Mailgun) to use it there directly, or download the HTML and upload it manually.<p>You can create any design structures using the row and column blocks. Nest the blocks however you like without constraints on how you use them to create structures. Combine the blocks to create complex designs or data tables for example.<p>I’d love to hear your feedback.

Show HN: Crul – Query Any Webpage or API
Hi HN, we’re Carl and Nic, the creators of crul (<a href="https://www.crul.com" rel="nofollow">https://www.crul.com</a>), and we’ve been hard at work for the last year and a half building our dream of turning the web into a dataset. In a nutshell crul is a tool for querying and building web and api data feeds from anywhere to anywhere.<p>With crul you can crawl and transform web pages into csv tables, explore and dynamically query APIs, filter and organize data, and push data sets to third party data lakes and analytics tools. Here’s a demo video, we’ve been told Nic sounds like John Mayer (lol) (<a href="https://www.crul.com/demo-video" rel="nofollow">https://www.crul.com/demo-video</a>)<p>We’ve personally struggled wrangling data from the web using puppeteer/playwright/selenium, jq or cobbling together python scripts, client libraries, and schedulers to consume APIs. The reality is that shit is hard, doesn’t scale (classic blocking for-loop or async saturation), and comes with thorny maintenance/security issues. The tools we love to hate.<p>Crul’s value prop is simple: Query any Webpage or API for free.<p>At its core, crul is based on the foundational linked nature of Web/API content. It consists of a purpose built map/expand/reduce engine for hierarchical Web/API content (kind of like postman but with a membership to Gold's Gym) with a familiar parser expression grammar that naturally gets the job done (and layered caching to make it quick to fix when it doesn’t on the first try). There’s a boatload of other features like domain policies, scheduler, checkpoints, templates, REST API, Web UI, vault, OAuth for third parties and 20+ stores to send your data to.<p>Our goal is to open source crul as time and resources permit. At the end of the day it’s just the two of us trying to figure things out as we go! We’re just getting started.<p>Crul is one bad mother#^@%*& and the web is finally yours!<p>Download crul for free as a Mac OS desktop application or as a Docker image (<a href="https://www.crul.com" rel="nofollow">https://www.crul.com</a>) and let us know if you love it or hate it. (<a href="https://forms.gle/5BXb5bLC1D5QG7i99" rel="nofollow">https://forms.gle/5BXb5bLC1D5QG7i99</a>) And come say hello to us on our slack channel - we’re a friendly bunch!
