How to target subdirectories in BuckleScript bsconfig.json

Question

I have the following folder structure

--| button
--|--| button.re
main.re

In my bsconfig.json, using the quickstart guide found here. I have in my config the following key/value:

"sources": [
  "src/"
]

It is only targeting the main.re file. I have tried some conventional config options such as *.re, but to no avail. If I would like to target all sub-directories, how would I do so? Thank you.

One way to circumvent the problem is to not have nested directories at all, and instead put all your source files in a single directory, with names like ui_Button.re. You'll then also need a 'table of contents' module for each level of the hierarchy to set up the nested module structure using module aliases, e.g. in ui.re: module Button = Ui_Button. – Commutable

Answer 1

There was actually a PR merged just yesterday that adds support for directory traversal. It'll be in the next release, which should be out shortly.

The configuration will then be:

"sources": [{"dir": "src", "subdirs": true}]

Edit: This feature was released in 1.9.2

I will say I am running across some errors using the above, and will try to be vocal in github repo. – Psychoneurosis

Happy to help! You're more than welcome to hop on to the Reason Discord to ask for help too. The author of BuckleScript hangs around there as well. – Mahon

Answer 2

Looking at documentation the solution would be the following:

"sources": [{"dir": "src", "subdirs": ["button"]}],
