the latest release is hosted at github releases

however, this project is rapidly changing. i recommend you build from source instead

install from source

you need zig 0.16.0 to build revo. i also recommend the anyzig version manager

linux/bsd/mac/etc

git clone https://github.com/if-not-nil/revo --recursive && cd revo
git submodule update --init --recursive
zig build --fetch
zig build -Doptimize=ReleaseSafe
                  # =ReleaseSmall for a ~1mb executable
                  # =ReleaseFast  for a ~5%-10% performance gain (harder to report bugs on)
cp ./zig-out/bin/revo ~/.local/bin/revo

revo

nix

this project has a flake which exposes revo as a package on default. you can open a shell with revo using nix shell github:if-not-nil/revo?dir=extra/nix. there is also a function that bundles a revo script into a nix package.

windows

[!NOTE] some features are unavailable on windows. i recommend using WSL with the linux steps

git clone https://github.com/if-not-nil/revo && cd revo
zig build --fetch -Doptimize=ReleaseFast

mkdir "C:/tools/revo/bin"
copy ./zig-out/bin/revo C:/tools/revo/bin

# now add it to PATH by doing:
# - Win+S -> `env` -> <Enter> -> "Environment Variables" -> "Path" -> "System Variables"
# - add new at "C:\tools\revo\bin" -> click ok -> reopen your terminal
