TenTags – Declarative (IR) for Documents

What it does

TenTags is an open-source declarative document language and Intermediate Representation (IR) for generating structured documents. Instead of embedding programming logic into templates, TenTags uses a compact semantic syntax that can be generated by Python applications and AI agents. Compile the same document definition into HTML, PDF, Excel (.xlsx), and future output formats while keeping business logic separate from presentation.

TenTags 2.5.1 is a declarative language for generating HTML, XLSX, PDF and DOCX documents from Python, with clickable linked images in PDF output.

TenTags is a declarative language designed for Python developers and AI systems to generate beautiful HTML, XLSX, PDF and DOCX documents from a single template. Wrap an <img> in <url> to make the image clickable. PDF output now creates a native URI link for external addresses and an internal destination navigation. The view prepares either one complete TenTags formula or separate preamble, style, and data blocks, then renders them with Django template tags. from django.shortcuts import render def index_view(request): user_name = "Qabylan Technologies" user_role = "Project Owner" inline_formula = ( f"1, 2, 1, '#38bdf8', 'solid', 0, 50, " f"data(User: {user_name}, Role: {user_role})" )…from tentags.org

  LLMs can generate valid JSON 100% of the time2023 · github.com · ▲854

  Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https:&#x2F;&#x2F;blog.normalcomputing.ai&#x2F;posts&#x2F;2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…

  HyTags – HTML as a Programming LanguageJan 2026 · hytags.org · ▲69

  This is hyTags, a programming language embedded in HTML for building interactive web UIs. It started as a way to write full-stack web apps in Swift without a separate frontend, but grew into a small language with control flow, functions, and async handling via HTML tags. The result is backend language-agnostic and can be generated from any server that can produce HTML via templates or DSLs.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
