parinfer-rust VS Fennel

parinfer-rust, while LISP only for reasons, is still absolutely amazing overall for its performance compared to the Lua version. I do wish there were more bracketing/scope algorithms out there for other languages. With a parinfer plugin, you only need to start a bracket for it to close what it believes is your scope. Great for enclosing things in functions

While my main daily driver is also IntelliJ, and also for Parinfer, I have found that Neovim + Rust-parinfer works remarkably well.

Another example where rust's benefits show is something like parfiner. Currently I'm using my own ffi interface to https://github.com/eraserhd/parinfer-rust, and it feels significantly faster than the plain-lua version I had before. Getting to write the whole thing in rust just makes life easier and simpler

I use a combination of parinfer-rust and Conjure for my Clojure, Janet, and Fennel development.

My personal configuration is also written in fennel if you would like to take. look: https://github.com/shaunsingh/nyoom.nvim. Neovim's come a long way in what you can do with it. Fennel has a macro system as with any lisp, so you can make the syntax feel right at home with emacs https://github.com/shaunsingh/nyoom.nvim/tree/main/fnl/macros. You can even create dynamic-module like integrations with rust programs (see https://github.com/shaunsingh/nyoom.nvim/blob/main/fnl/parinfer/init.fnl, interacting with https://github.com/eraserhd/parinfer-rust/tree/master/src)

eraserhd/parinfer-rust if you do any sort of Lisp programming

Clojure is an amazing language, and so is Rust. In fact, I think learning both of them is a wonderful way to introduce ourselves to such a broad range of programming ideas that it covers over half of the seven programing ur-languages. It's even worth investigating the differences in the way these languages have developed over time (Clojure being Rich's project and Rust taking a community approach). These ideas aren't in opposition to each other. If they were, the indispensable editor plugin I use to write Clojure wouldn't exist for crying out loud.

Have you seen an excellent parinfer-rust implementation of Parinfer? It's quite fast and can be integrated with other editors, like Emacs, Kakoune, Vim, etc. I think you can try to see if your integration passes their tests.

I am currently using parinfer. It’s not exactly minimal, but it doesn’t require much configuration and doesn’t have any special keybinds.

Eh it's not just luajit and luajit didn't create that problem either. It's a symptom of lua actually succeeding at its design goal of being easily embedded as an extension language. A significant number of incompatible runtimes are more popular than the most recent puc lua, including I believe the older official lua 5.2 released in 2011.

I've done a fair bit of professional lua development and I don't think I've ever written standalone up-to-date puc lua except maybe for some tooling & scripts. It's such a small language and used in such a way that the runtime, distribution method, and available APIs have much more impact on your use (and compatibility) than the version.

Virtually everyone shipping a lua environment is also shipping changes to it that make it a unique target, if only extensions to the standard library. This is why I think syntax layer-only approach like fennel's is the correct choice for improving on lua. It mirrors lua's runtime semantics exactly, and allows you to access the implementation peculiars on their own terms and so can just be run on time of any lua system.

Just learned about https://fennel-lang.org/ , could have probably used that as well to avoid Lua.

> I’m positive that there is a Lispy language out there (actually in existence, or the aether) that is appropriate for embedded work, but the constraints of the target make it difficult to envision.

Perhaps Fennel* fits the bill?

I've also seen neovim plugins written in fennel [0], so if you want something lispy, that's possible now.

[0]: a Lisp that compiles to Lua, https://github.com/bakpakin/Fennel

Something similar: Fennel (https://fennel-lang.org/) is a lisp that compiles into Lua, which nvim can use as plugins, so you can write nvim plugins in a lisp. Aniseed (https://github.com/Olical/aniseed) makes this really easy.

If you want a more FP language on the Lua runtime, you might be interested in Fennel. I wrote a post about adding Fennel compiler to a hslua interpreter a while back, which might be useful for you.

There's fennel if you're a fan of LISP syntax. I like embedding lua because it's light and easy and doesn't re-engineer itself every six months like python; but I agree, the lua syntax certainly is fugly.
