Languages

JavaScript

JavaScript runs everywhere — browsers, servers, build tools, edge workers. Sharing a snippet should be just as portable.

TypeScript

TypeScript adds static types on top of JavaScript. CodeThis preserves the generics, inference, and decorators in the paste.

PHP

PHP powers WordPress, Laravel, and a surprising amount of the internet. Paste modern PHP 8+ with attributes and union types.

HTML

Share semantic HTML, form markup, and structured-data blocks with inline CSS and JavaScript syntax-aware.

CSS

Modern CSS — grid, flex, container queries, custom properties — all highlighted and shareable.

SCSS

Sass with curly braces. Share mixins, partials, and utility generators.

Vue

Single-file components with <script setup>, composables, and scoped styles — rendered exactly how you wrote them.

JSX

React JSX snippets with props, hooks, and context — share a component without spinning up a sandbox.

TSX

TypeScript JSX for React. Props, generics, and discriminated unions preserved.

Python

Python is the default language for data, scripting, and teaching. Paste a notebook-free snippet when you need to share results without the Jupyter overhead.

Ruby

Ruby still reads like pseudocode. Paste a Rails snippet, a Sinatra endpoint, or a metaprogramming trick.

Lua

Lua for Neovim plugins, Roblox scripts, and embedded game logic.

Rust

Rust shines when you want to share a snippet with borrows, lifetimes, and trait bounds intact. CodeThis highlights all of it.

Go

Go's whole appeal is that a snippet is a complete program. Paste it, get a link, share with a teammate — same workflow.

C++

C++ snippets with templates, concepts, and the standard library — all highlighted correctly.

C

The language underneath most of computing. Share POSIX, pointer arithmetic, and tight loops with clean highlighting.

Java

Java still runs the enterprise. Share classes, interfaces, and records with full syntax highlighting.

Kotlin

Kotlin makes JVM code read like Swift. CodeThis keeps coroutines, extension functions, and sealed classes all syntax-aware.

Swift

Swift for iOS, macOS, and server-side. Paste a snippet and send it to a teammate without spinning up Xcode.

C#

C# snippets with records, pattern matching, and LINQ — complete with async/await syntax highlighting.

SQL

Share SELECTs, CTEs, and window functions. Postgres, MySQL, SQLite — all highlighted.

JSON

Share API responses, config files, and JSON schemas — pretty-printed and syntax-highlighted.

YAML

YAML for Kubernetes, GitHub Actions, and config files. Share with structure preserved.

TOML

TOML for Cargo, pyproject, and other config files. Shareable with full highlighting.

GraphQL

Share schemas, queries, mutations, and subscriptions with field-aware highlighting.

Bash

Shell scripts, one-liners, and pipelines — preserved without the terminal's copy-paste weirdness.

PowerShell

PowerShell on Windows, macOS, and Linux. Share cmdlets, pipelines, and automation scripts.

Markdown

Render Markdown as rich documentation — not just highlight it. CodeThis MDC supports alerts, callouts, and code groups too.

Dockerfile

Share Dockerfiles for reproducible builds and multi-stage patterns.

Elixir

Elixir for fault-tolerant, concurrent systems. Share Phoenix LiveView, GenServers, and pattern-matched functions.
