Reflex CLI

Reflex REPL environment and standalone script runner

What is Reflex CLI?

Reflex CLI is a command-line tool that exposes the Reflex reactive programming language ecosystem both via an interactive REPL interface and via a standalone script runner interface.

Getting started

Build the reflex-cli executable via cargo:

cargo build --release --workspace --package reflex-cli --bin reflex-cli

Once the reflex-cli executable has compiled successfully, it can be used in one of two modes.

Option 1: Interactive mode

Run reflex-cli executable with no arguments to launch an interactive REPL session:

$ reflex-cli
> 1.2 + 3.4
4.6
> ((x, y) => x + y)(1.2, 3.4)
4.6
> exit

The session can be terminated either by entering the exit REPL command or sending the Ctrl+C signal (SIGINT)

The default REPL syntax is a subset of JavaScript syntax, provided by the ReflexJS package. Alternative syntaxes can be specified via the --syntax CLI argument:

$ reflex-cli --syntax lisp
> (+ 1.2 3.4)
4.6
> ((lambda (x y) (+ x y)) 1.2 3.4)
4.6
> exit

Option 2: Script mode

For examples of using Reflex CLI to execute scripts directly, see the examples directory within this package.

For more information on the various reflex-cli CLI options, run the reflex-cli --help command.
