slint
Slint is an open-source declarative GUI toolkit to build native user interfaces for Rust, C++, JavaScript, or Python apps.
> I wonder if someone could make a decent cross-platform GUI toolkit to save us from the horribly slow Electron-hell we've carved out for ourselves.

Project mention: Exploring Typst, a new typesetting system similar to LaTeX | news.ycombinator.com | 2024-10-12
Writing Typst in Emacs is pretty easy with this setup.

Project mention: NixOS is a good server OS, except when it isn't | news.ycombinator.com | 2024-10-01
This is inherently a Hard Problem™, since completions may require evaluating arbitrary derivations (e.g. building a custom Linux kernel).
For "what symbols are available", the nil LSP implementation[1] works for anything in scope that doesn't require evaluation. It also includes completions for the stdlib and NixOS options (in certain contexts).
Another LSP implementation is nixd[2], which is trying to tackle the problem of evaluations for completion.

Project mention: Show HN: Daily-notes.nvim – fuzzy time journal and planning plugin | news.ycombinator.com | 2025-02-08
The PKM space for neovim plugins is a surprisingly deep rabbithole but it can take quite a while to find what you need.
For completions and tagging https://github.com/Feel-ix-343/markdown-oxide works well for me and does pretty much everything I need.
There are also a glut of all-in-one solutions like https://github.com/nvim-neorg/neorg (org-mode for neovim) and https://github.com/epwalsh/obsidian.nvim.
Graphing is a bit harder because it doesn't intuitively match up with nvim's interface, but I'm pretty sure I saw something on Reddit the other day.

Fennel is indeed nice and I rewrote my config too, but looked back ~2 years later and rewrote in again in Lua. I think Fennel for configuration is not justified and just adds complexity. Also the tools are not there: two existing language servers[1][2] can't compete with Sumneko's Lua language server[3] and they are fennel-exclusive and clueless about Lua code. I still like Fennel for writing more complicated code (my plugins: [4][5]) because of neat features like pattern matching and structural decomposition, both are surprisingly robust and I had doubts initially.
