   LLMs can generate valid JSON 100% of the time▲854

   HyTags – HTML as a Programming Language▲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.

    Docfd: TUI multiline fuzzy document finder▲44

    Think interactive grep for text files, PDFs, DOCXs, etc, but word/token based instead of regex and line based, so you can search across lines easily. Docfd aims to provide good UX via integration with common text editors and PDF viewers, so you can jump directly to a search result with a single key press. --- I originally wrote this tool to help me dig through text/markdown notes, since very often I want to search for a phrase of sorts that may span across multiple lines, but constructing the corresponding multiline regex is a bit painful (especially painful if I want to account…
