# SMM 3 - a Metamath database processor

## A what?

Metamath is a language for expressing formal proofs, which makes few assumptions on the underlying logic and is simple enough to support a wide variety of tools.
See http://us.metamath.org/#faq.

## Building

Install Rust ([rustup.sh]), version 1.9.0 or later, then check out this repository and run:

cargo build --release

Alternatively using `cargo install`:

cargo install --git https://github.com/sorear/smetamath-rs
# $HOME/.cargo/bin/smetamath has been installed, use it as the binary in the following instructions

## Running

# The largest known Metamath database, and best test case
git clone https://github.com/metamath/set.mm

# One-shot verification using 4 threads
target/release/smetamath --timing --jobs 4 --split --verify set.mm/set.mm

# Incremental verification
(while sleep 5; do echo; done) | target/release/smetamath --timing --jobs 4 --split --repeat --trace-recalc --verify set.mm/set.mm
# then make small changes to the beginning, end, or middle of the DB and observe how behavior changes
