• STXT, indentation-based format with schemas and no escape characters 0 open listings

  discussion=https://news.ycombinator.com/item?id=49681808, title=Show HN: STXT, indentation-based format with schemas and no escape characters, STXT is a human-first text format for documents: it has very few rules and is designed around simplicity and readability. The goal is a language that people write naturally, and machines parse securely and reliably. Compared with XML, you keep namespaces and schemas, but without closing tags or escape characters. There is no entity expansion or external resource references either. Compared with YAML or TOML, every value is text (no Norway problem), a text block is literal, and schemas are STXT documents too. The combination of STXT and Markdown allows validated and structured documents, with the expressiveness of Markdown. To explain it, I've created the main portal https://stxt.dev , made with STXT itself (add .stxt to any URL to see the source). In the portal you can find all the specifications, the tutorial, VSCode extension, a CLI, parsers in Java, TypeScript, Python, and a playground: https://play.stxt.dev . All available in https://github.com/stxt-lang/ . An example in STXT (extra indentation for HN): Book (com.example.library): Title: Modern Software Architecture Authors: Author: Keyla Brown Author: Joan Costa ISBN: 978-84-123456-7-4 Published: 2026-08-25 Summary >> This book offers a practical view of patterns and best practices for designing distributed, scalable systems. And the template with the structure and cardinality: Template (@stxt.template): com.example.library Structure >> Book: Title: (1) Authors: (1) Author: (+) ISBN: (1) Published: (1) DATE Summary: (?) TEXT Why STXT? I created STXT in the spring of 2013, as a language that preserves the most used of XML, while being able to be written by non-technical people. The first version was finished, different from the current one, but I never announced it. In 2014 my daughter was born; my priorities changed. Time passed, other languages were created, and we arrived at 2025. In those years I didn't find another format with the same balance of characteristics that STXT has, and I decided that was the time to resume the project. Since then, I've been revising the language, using it for personal projects, and I consider it usable and stable. I'd love to have your feedback, impressions and comments.

• SeaSearch 0 open listings

  discussion=https://news.ycombinator.com/item?id=49721546, title=Show HN: SeaSearch – Lightweight, S3-backed multi-tenant search engine, Hi HN, I'm Daniel, co-founder of Seafile. I'm glad to share our open-sourcing project SeaSearch, a search engine written in Go (built on ZincSearch) that we’ve been running in production for over two years for Seafile project. After years of using Elasticsearch, we think there are two main problems with Elasticsearch: It is not lightweight and hard to maintain a cluster All of seafile tenants' data was stored in a single index and it is slow to search a file in a single library because the whole index need to be searched Three years ago, we started developing a solution to solve the two problems. Rather than building a search engine from scratch, we built on top of ZincSearch, that is implemented in Go rather than JVM with a smaller runtime footprint and has Elasticsearch API compatibility, but it was still missing something that we get to find out along the way. We have now open-sourced SeaSearch with the pieces we needed: S3-backed Storage: Index data lives in S3. Compute nodes share the same backend, making scaling/failover instant (no data replication needed). Smart Caching: Uses a local disk cache for immutable segments to keep things fast despite the S3 backend. ES API Compatible: Works as a drop-in replacement for most Elasticsearch query endpoints. Lightweight Go Runtime: No JVM overhead. Vector Search: Built-in support for HNSW/IVFPQ for hybrid semantic search. Hope this helps fellow devs who are stuck in this problem when building multi-tenant SaaS applications. Looking forward to your responses.
