Software developer. C# by day at Digitech Computer, Rust by night building things I want to use every day, most recently a terminal emulator.

About

I like tools that stay out of the way: native, fast, configured in a text file, and quiet on the network. Most of my time lately goes into desktop software in Rust, which means a lot of GPU rendering, PTYs, filesystem watchers, and the odd Objective-C bridge.

When I'm not shipping Oxide I'm usually working through a compilers or systems book, poking at Zed's UI framework, or automating something small that annoyed me twice.

Digitech Computer

Software Developer, C# / .NET

My full-time job. I build and maintain C# applications at Digitech Computer, which is where most of my professional experience lives: .NET services, data-heavy business software, and the long tail of keeping production systems reliable.

Oxide Terminal

Oxide

A native terminal for macOS and Linux, written entirely in Rust. Rust is iron oxide. It's a whole thing.

Oxide is a GPU-rendered terminal built on GPUI (Zed's UI framework) and Alacritty's PTY and VT parser. The things you'd normally bolt on with plugins and dotfiles, a file tree, tmux-style workspaces, a powerline prompt, a vim copy mode, are built in and configured in one TOML file that reloads when you save. No account, no AI, no telemetry. The only thing it asks the network is whether GitHub has a newer release.

Real terminal. Full VT emulation: truecolor, wide glyphs, bracketed paste, SGR mouse, OSC 8 links, OSC 52 clipboard. vim, htop and tmux just work.
File tree drawer. Follows the focused pane's directory, modeless vim navigation, type-to-filter, add/rename/move/trash, git-status colouring.
Tree ↔ terminal seam. y inserts a path at the prompt, cmd-click a path:line:col to open it in $EDITOR, cmd-p fuzzy-finds any file.
Copy mode. ctrl-w [ turns scrollback into a vim buffer: motions, counts, search, visual select, yank.
Splits, tabs, workspaces. tmux-style, with a command palette that lists every action and its binding.
Status bar that knows things. Git branch and state, SSH host awareness with per-host accent colours, prompt jumping through scrollback.
Scrollback search. Live, with regex, case and whole-word toggles, and a malformed regex says so instead of matching nothing.
Themes and Markdown. A theme picker that repaints as you browse, and rendered .md preview with highlighted code.

Install on macOS:

$ brew install --cask bobbycoleman-dev/tap/oxide-terminal

Builds are Developer ID signed and notarized and update themselves. Linux gets a PKGBUILD and a release tarball with a no-root install.sh. Oxide never writes to your dotfiles.
