tla-bin is a wrapper around https://github.com/tlaplus/tlaplus that provides command line binaries for pcal, tlc, tlatex and sany, making automation around TLA+ easy. Also provides a binary that starts the TLA+ REPL.
$ git clone https://github.com/pmer/tla-bin.git
$ cd tla-bin
$ ./download_or_update_tla.sh
$ sudo ./install.sh
The download_or_update_tla.sh script takes an optional --nightly argument.
If passed, it will download the nightly CI build of TLA+ rather than the latest
release.
The install.sh script takes an optional location argument. By default,
binaries and the tla jar file are installed below /usr/local.

Computing initial states...
Finished computing initial states: 1 distinct state generated at 2021-11-28 16:13:57.
Model checking completed. No error has been found.
Estimates of the probability that TLC did not check all reachable states
because two distinct states had the same fingerprint:
calculated (optimistic): val = 2.7E-19
6 states generated, 5 distinct states found, 0 states left on queue.
The depth of the complete state graph search is 5.
The average outdegree of the complete state graph is 1 (minimum is 0, the maximum 1 and the 95th percentile is 1).
