Tish - Native Performance, Familiar Syntax

Create a Tish file

Create main.tish:

fn greet(name) {
    return `Hello, ${name}!`
}
 
console.log(greet("Universe"))

Run with the interpreter

tish run main.tish

Output: Hello, World!

To try code interactively with multi-line input, tab completion, and history, use the Interactive REPL: run tish with no arguments in a normal terminal (stdin is a TTY).

Run from stdin

You can pipe a program instead of using a file (like node - or bun with a pipe):

echo 'console.log("Its")' | tish
echo 'console.log("a small")' | tish run -
echo 'console.log("universe")' | tish -

When stdin is not a terminal, bare tish reads the full script from stdin and runs it once. See Installation for the full table of variants.

Compile to native binary

tish build main.tish -o wasup
./wasup

Same output. The compiled binary has no runtime dependency on Tish.

For backend options (Rust vs Cranelift), see Native Backend. For WebAssembly (browser or Wasmtime), see WASM Targets.

HTTP server (requires `http` feature)

Create server.tish:

fn handleRequest(req) {
    return { status: 200, body: `Hello, ${req.path}` }
}
 
serve(8080, handleRequest)

Run (the tish binary must be built with the http feature):

cargo run -p tishlang--features http -- run server.tish

Or compile to a standalone binary:

tish build server.tish -o server --feature http
./server

Then visit http://localhost:8080/.
