rescript-lang.org

This is the official documentation platform for the ReScript programming language.

In case you want to report a technical issue, please refer to the appropriate repository:

• rescript-compiler: The compiler and build system
• rescript-syntax: The ReScript syntax

Setup

# For first time clone / build
yarn
yarn run update-index

# Initial build
yarn bs:build

# In a new tab
yarn dev

# then open localhost:3000

In case you want to run BuckleScript in watchmode:

yarn run bs:start

Build Index Data

We are parsing our content for specific index data (such as, all interesting search terms we need for searching inside the Belt docs). You can create your index by running following command:

yarn run update-index

All the index data is stored in index_data, but will not be tracked by git. Make sure to build the index after a fresh clone, otherwise Next might not build specific pages (file index_data/x.json not found).

Run Tests

Markdown Codeblock Tests

We check the validity of our code examples marked with:

• ```res example (ReScript code snippet)
• ```res sig (signature)
• ```res prelude (ReScript code snippet available for all subsequent code snippets)

Run the checks with:

node scripts/test-examples.js

Markdown Hyperlink Tests

We are also verifying markdown href links to relative resources (via [text](url) syntax) with our scripts/test-hrefs.js script. Here is a short explanation on how the href testing works:

Domain relative links, such as /docs/manual/latest, ./introduction, introduction, /docs/foo/introduction.md will be verified. That means the tester will check if given path exists in the pages directory.

If there are any anchor refs, such as /docs/manual#test, then the anchor will be ignored for the specific file path check. If there are any hrefs with .md, .mdx or .html file extension, then those will be stripped before the check happens (the markdown renderer drops file extensions on relative links as well).

External hrefs, such as https://www.hello.world, //www.hello.world will NOT be checked since they are assumed to be external resources.

Here is an example on how to run the tests:

# Tests all files
node scripts/test-hrefs.js

# Or just a subset (glob pattern)
node scripts/test-hrefs.js "pages/docs/manual/**/*.mdx"

Continous Integration

Always make sure to run npm test before pushing any content, otherwise our CI might trigger a failure warning. Failing branches are very unlikely to be merged.

Design / UX

Design mockups can be found here.

Be aware that some screen designs might still be work in progress, if you have any design / UX questions, either comment directly on the design tool as guest, or open an issue.

Useful commands

Build CSS seperately via npx postcss (useful for debugging)

# Devmode
npx postcss styles/main.css -o test.css

# Production
NODE_ENV=production npx postcss styles/main.css -o test.css

Writing Blog Posts

In case you are a blog author, please refer to our guide on writing blog posts.

Quick-takeaways:

• Blogposts are located in _blogposts
• Author metadata is located in index_data/blog_authors.json
• Make sure to follow the file naming rules
