Show HN: Sfsym – Export Apple SF Symbols as Vector SVG/PDF/PNGhttps://github.com/yapstudios/sfsymI found myself reaching for SF Symbols' 'Copy Image As…' quite often during agentic design sessions, so I made a command-line tool that the agent can use by itself. It exports Apple SF Symbols as SVG, PDF, or PNG.The vector paths come directly from macOS's symbol renderer. Internally it reaches a private ivar on NSSymbolImageRep to get the CUINamedVectorGlyph, draws into a CGPDFContext, then walks the PDF content stream back out as SVG `d` commands. The output matches what the system draws, rather than an approximation traced from rasters.A few things about it:- Every subcommand accepts `--json`, and `sfsym schema` returns a machine-readable description of the whole CLI. - Symbol enumeration reads the OS's Assets.car BOM tree, so the list of 8,300+ names stays current with macOS updates without a version table in the binary. - Each SVG `` carries a `data-layer` attribute, so you can retheme in CSS without touching geometry.It's been saving me a bunch of clicking.

A vectorized Search Visualizer written with NumPyhttps://news.ycombinator.com/item?id=38837699Hey Y Combinator community,Last semester, I delved into a Data Structures and Algorithms course with a hunger for visualizing complex algorithms and data structures.While I found some success using [grid-based search visualizers](https://i.imgur.com/4jQwRHu.png), my desire for a versatile graph search visualizer persisted.So, I decided to create one. Now, it not only supports generic graph search visualization but also tackles challenges like the traveling salesman problem and various other graph-based algorithms.The API is straightforward. The `graphViz` module provides granular access at the node and edge levels within a given `Graph` object, allowing you to dynamically alter colors while running your graph-based algorithm.For a more in-depth understanding, I've put together:- [A detailed walkthrough of recent updates](https://youtu.be/BKF-PEgd1PA) - [A concise overview of the initial version](https://youtu.be/kNGsOoWh9fM)I'd love for you to check out the [GitHub Repo](https://githubJan 2, 2024 3:20 AM
