I think I've stumbled onto a niche for a new language that will actually be useful to me.
The syntax will be Lisp, for my own sanity. (Lately, any other programming language syntax looks much more inconsistent in comparison.)
It will run a virtual machine that interprets a custom form of bytecode. This virtual machine will be fast using a combination of tricks I've been collecting. It'll trade memory for speed in most places, since we have tons of memory these days.
The parser and compiler will be available at runtime, enabling
eval and thus a REPL.
All data types will be purely immutable. This assumption will enable several optimizations, as well as a simpler virtual machine.
It will have linked-lists, vectors, hash-maps, strings, symbols, keywords, and 64-bit numbers. I'm not worried about floating point numbers for now.
It will have macros that are executed before the final translation to bytecode. They're basically user customizable compiler optimizations that you write in the language itself. All the types will be available at macro-execution time. Macros will take an AST and transform it into a new AST that's then compiled into bytecode.
The interpreter technique is very similar to Lua's, except it'll have a much nicer extension API than Lua's (at least I think so).
The language will be "tiny" by default, much like Lua (but not nearly as tiny as Lua). It will have a small set of functions to accompany the built-in data types, very similar to
People have argued that Ruby and Python are better for general programming than Lua because Lua comes with nothing built-in, but actually Ruby is moving in the same direction: they have a goal of turning most (if not all) of the Ruby standard library into gems. I'll follow suit by offering other "standard" library functions through some package manager, so users can pick and choose what they want to use.
The main benefit of this approach is that this language could be embedded into another application very easily, with only the libraries the embedder chooses to bring with it.
I'm not at the point where I can fully write something like this yet. Even though I could write much (maybe all) of the core language, I don't know how to do things like providing detailed backtraces or enabling a symbolic debugger.

Here are some of the projects I'm most proud of. They were created using a variety of technologies, running on several different platforms and OSes. They're all finished products, and many of them are open source.
I made Docks in 2009 for users who wanted to swap out icons in their Dock with a single click. Its unique functionality and design aesthetic attracted the attention of Apple, Engadget, MacWorld, and led to an acquisition of my start-up by Big Nerd Ranch.
This toy was made in a weekend to entertain my 1 year old daughter. It lets you create bubbles with your fingers, which then simulate physics by bumping into each other and falling.
When I couldn't find an app in the App Store that let me make very simple lists extremely quickly, I made one myself. I use it almost every day to organize and track my activities.
I created this app to increase my productivity by letting me move windows around in macOS using keyboard shortcuts. It grew into a community-driven highly extensible app, using Lua for its plugin system.
Implementing this elite social network gave me experience integrating both Apple Pay and credit card payments (via Stripe.com) seamlessly into web apps, for a frictionless and pain-free payment experience.
This isn't just any chatroom. In this web app, you can see what everyone is typing while they type it. I made this in order to scratch my itch for making real-time apps and games, and learned how to use WebSockets in the process.
This was written in 2009, before the time of Slack, when IRC was the main way for programmers to get short-term assistance from each other. Its purpose was to be a beautiful app with an emphasis on simplicity and usability over technical power.
This is an app I actually use every single day. It lets you move windows with global keyboard shortcuts. Since it uses Vim-like key bindings, it should feel pretty natural to any programmer. There's no configuration needed; it Just Works™.
As an evolution of Phoenix, Hydra was my first attempt at embedding a full Lua virtual machine into an Objective-C app, to make a lightweight and efficient window manager that focused on speed, low memory usage, low CPU usage, and overall being gentle on laptop batteries.
These may be tiny, but they're interesting technical feats.
