Build & Install
Download a prebuilt binary (recommended)
Prebuilt native-image binaries are published on the
GitHub releases page.
They start instantly and need no JVM installed. Pick the asset for your platform,
make it executable, and put it on your PATH as rontolisp.
macOS (Apple Silicon):
wget https://github.com/making/rontolisp/releases/download/0.1.0-SNAPSHOT/rontolisp-darwin-arm64
chmod +x rontolisp-darwin-arm64
sudo mv rontolisp-darwin-arm64 /usr/local/bin/rontolisp
Linux (x86-64):
wget https://github.com/making/rontolisp/releases/download/0.1.0-SNAPSHOT/rontolisp-linux-amd64
chmod +x rontolisp-linux-amd64
sudo mv rontolisp-linux-amd64 /usr/local/bin/rontolisp
Linux (ARM64):
wget https://github.com/making/rontolisp/releases/download/0.1.0-SNAPSHOT/rontolisp-linux-arm64
chmod +x rontolisp-linux-arm64
sudo mv rontolisp-linux-arm64 /usr/local/bin/rontolisp
Verify the install:
rontolisp --version
A prebuilt binary needs nothing else installed. To run .wasm output you also
need a wasm-GC capable runtime such as wasmtime 14+
(optional).
The rest of the documentation uses the rontolisp command. If you build from
source instead (below), substitute java -jar target/rontolisp-0.1.0-SNAPSHOT-exec.jar
for rontolisp.
Download the executable JAR
The same releases page
also publishes the self-contained executable JAR
(rontolisp-0.1.0-SNAPSHOT-exec.jar). It needs a Java 25+ runtime but works on
any platform, and it is the only artifact that can interpret the JVM-only
java: interop package — the native binaries carry
no reflection metadata, so interpreting java: forms fails there (both
artifacts can still compile a java: program to a .class that runs under
java).
wget https://github.com/making/rontolisp/releases/download/0.1.0-SNAPSHOT/rontolisp-0.1.0-SNAPSHOT-exec.jar
java -jar rontolisp-0.1.0-SNAPSHOT-exec.jar --version
Build from source
Requires Java 25+.
./mvnw clean package
This produces target/rontolisp-0.1.0-SNAPSHOT-exec.jar, an executable JAR with
all dependencies included. Run it with java -jar target/rontolisp-0.1.0-SNAPSHOT-exec.jar.
Native Image (GraalVM)
Build a native executable yourself using GraalVM:
./mvnw -Pnative clean package
This produces target/rontolisp, a standalone native binary with instant startup.
Requirements:
- GraalVM 25+ (with
native-imagetool)
Usage:
# REPL
rontolisp
# File interpretation
rontolisp program.lisp
# Compile to JVM bytecode
rontolisp hello.lisp -o Hello.class
# Compile to WASM
rontolisp hello.lisp -o hello.wasm
