history
Project history and usage
Spot is a C++ library and suite of command-line tools for linear temporal logic, omega-automata manipulation, and model-checking workflows.
Project history
The official homepage describes Spot as a C++20 library for LTL, omega-automata manipulation, and model checking, with algorithms for formula manipulation, automata transformation, reactive synthesis, and model checking. It also exposes most algorithms through command-line tools and Python bindings.
Adoption history
Spot has official source releases, Debian and Fedora repositories maintained by the project, Conda-forge availability, and package-manager entries recorded in the input for Homebrew, MacPorts, and Nix. Its package footprint reflects both research users who need libraries and CLI users who need tools such as ltl2tgba, autfilt, randltl, and ltlcross.
How it is used
Common use is formal-methods automation: translate LTL or PSL formulas to automata, filter or transform automata, generate random formulas or automata, and benchmark translators with cross-checking tools. The command-line tools matter because they let researchers and verification engineers compose Spot behavior in shell pipelines and experiments.
Why package nerds care
Spot is package-nerd relevant because it is not just one executable: it ships a library, development headers, Python bindings, documentation, and many specialized binaries. Packagers have to preserve that split while keeping compiler, Python, and documentation dependencies sane.
Timeline
- 2026-04-25: Official homepage lists Spot 2.15.1 as the latest release.
- 2026: Install page documents project-maintained Debian and Fedora repositories plus Conda-forge availability.
- Current: Git install instructions point to the official GitLab repository.
Related projects
- The homepage identifies ltlcross as a rewrite of LBTT and describes autcross as a similar checker for automata-transforming tools.
