#!/usr/bin/env node
/*
 * Release announcement drafts for X, Discord and Reddit, built from the
 * version's section of CHANGELOG.md.
 *
 * Usage
 *   make release-post                             # = node scripts/release-posts.js
 *   node scripts/release-posts.js                 # version from VERSION
 *   node scripts/release-posts.js 5.35.0
 *   node scripts/release-posts.js --only discord  # print one platform
 *   node scripts/release-posts.js --out /tmp/posts   # write there instead
 *   node scripts/release-posts.js --prerelease | --stable   # override detection
 *   node scripts/release-posts.js --url https://…      # override the release link
 *
 * Writes one file per thing you paste to `.release_posts/v<version>/` (git-ignored), shaped
 * for each platform:
 *   X        plain text, no markdown; 280 characters with every link counted as 23. A short
 *            main post with the link (X shows the release as a card), then a reply thread.
 *            One file per post: x-1-main.txt, x-2-reply.txt, …
 *   Discord  markdown: ## heading, bullets, **bold**, `-#` small print, [named links](<url>)
 *            (the <> stops Discord from embedding each link). 2000 characters at most.
 *   Reddit   the title and the body are separate boxes: reddit-title.txt, reddit-body.md
 *            (markdown, ### headings, named links).
 * plus README.md: what to paste where, with each post's length.
 *
 * The changelog section is read as groups: a bold paragraph line
 * (`**One install path for everything.**`) starts a group, and each `- `
 * bullet under it — including its wrapped continuation lines — is one item.
 * An item's bold lead (`- **Stream install.** Longer text…`) is its short form.
 *
 * Pre-release status comes from `gh release view` when gh is available, so
 * the posts say "pre-release" exactly when GitHub does; pass --prerelease or
 * --stable to decide it yourself.
