Tact

Building from source

Install opam using this guide
Run following commands:

opam init
opam switch create $(pwd) --with-test -y
eval $(opam env)
dune build && dune install

You can now use tact /path/to/file.tact

Development instructions

Updating dependencies

Run opam install . --working-dir --deps-only --with-test

Running REPL

Run dune utop lib

Running tests

Run dune test

Formatting code

Run dune build @fmt --auto-promote (or no --auto-promote if you want to review changes, followed by dune promote)

Working with expect-based tests

ppx_expect ppx_expect tests allow to check output against an expectation and upon failure, they produce a diff, which can be easily applied to the original source code by running dune promote if the output is deemed to be correct. This allows us to write:

pp source ; [%expect {||}]

to fill in the blanks. In this particular case, it's useful to run dune test --auto-promote

JavaScript bindings

Can be built during dune build or dune build js and will be available in _build/default/js/tact_js.bc.js

In order to build a (smaller) release build, one should run:

dune build js --profile=release
