structured-text

Tools for the IEC 61131-3 structured text (ST) language. See: https://en.wikipedia.org/wiki/IEC_61131-3.

Build and install (on Ubuntu 20.04)

1. Install the haskell-stack package:

   $ sudo apt install haskell-stack

2. Clone this repo:

   $ git clone git@code.ornl.gov:defcon-scada/structured-text.git

3. Enter the repo:

   $ cd structured-text

4. Build and install:

   $ stack install

   This step will take a while the first time, as it'll install Haskell and all the build dependencies as well.

5. Add stack's default executable deployment directory to $PATH:

   $ export PATH=$HOME/.local/bin:$PATH

   Also consider adding this to ~/.bashrc.

Testing

To run the unit tests:

$ stack test

Usage

The stack install command should build the executable stxt. For usage info:

$ stxt --help
