This project uses Ocaml to enhance the experience on google apps script. It targets a very specific spreadsheet of mine, but it is an interesting experiment.
It uses parcel for an easy, (almost) setup free building experience.
As standard library we use reason-standard.
In the future, when TableCloth gets its latest version published we may migrate to it.
Also, we are using an older version of bucklescript (bs-platform) because reason-standard does not work on newer ones (7.3 and up)
The google apps script main file needs to be kept in JS, that is the index.js file.
The rest of the files are under src and are all OCaml files that get compiled to an UMD file.
The reason to do this is because GAS does not allow import or require, only global functions and variables.
So, all the Ocaml files are (for now) compiled under a global variable named Util using the --global option of parcel (that is effectively UMD).
Of course all the required scripts to build are under package.json scripts section, so all you need to do is:
yarn deploy
For the entire flow (build and publish)
or just yarn build if you only want to build.
In order to publish/deploy you need to have clasp globally installed and you need to be logged in with clasp login.
