In the browser, + the archive is `http://127.0.0.1:8788/archive` (optionally + `?collection=<slug>`); collections are `/collections` and `/collections/<slug>`. diff --git a/resources/skills/pena/scripts/publish-document.mjs b/resources/skills/pena/scripts/publish-document.mjs deleted file mode 100644 index 93a5c69..0000000 --- a/resources/skills/pena/scripts/publish-document.mjs +++ /dev/null @@ -1,216 +0,0 @@ -import { readFile } from "node:fs/promises"; - -const args = parseArgs(process.argv.slice(2)); - -if (args.help) { - process.stdout.write( - [ - "Usage:", - " node publish-document.mjs --document <slug>", - " --title <title> --file <markdown-path> --create", - " [--collection <slug> | --root]", - " node publish-document.mjs --document <slug>", - " --title <title> --file <markdown-path> --etag <etag>", - " [--collection <slug> | --root]", - " [--feedback-match <batch-id>]", - " [--base-url <url>]", - "", - ].join("\n"), - ); - process.exit(0); -} - -const document = requireValue(args, "document"); -const collection = - typeof args.collection === "string" ? args.collection : null; -const root = args.root === true; -const title = requireValue(args, "title").trim(); -const file = requireValue(args, "file"); -const create = args.create === true; -const etag = typeof args.etag === "string" ? args.etag : null; - -if (collection !== null && !/^[a-z0-9]+(?:-[a-z0-9]+)*$/.test(collection)) { - fail("The collection slug is invalid."); -} - -if (collection !== null && root) { - fail("Pass either --collection or --root, not both."); -} - -if (!/^[a-z0-9]+(?:-[a-z0-9]+)*$/.test(document)) { - fail("The document slug is invalid."); -} - -if (title.length === 0 || title.length > 200) { - fail("The title must contain 1 to 200 characters."); -} - -if (create === (etag !== null)) { - fail("Pass exactly one of --create or --etag."); -} - -if ( - args["feedback-match"] !== undefined && - !/^[1-9]\d*$/.test(String(args["feedback-match"])) -) { - fail("--feedback-match must be a positive feedback batch ID."); -} - -let content; - -try { - content = await readFile(file, "utf8"); -} catch (error) { - fail(`Could not read the Markdown file: ${errorMessage(error)}`); -} - -if (hasLeadingH1(content)) { - fail( - "The Markdown body must not repeat the document title as a leading H1.", - ); -} - -const headers = { - "content-type": "application/json", - ...(create ? { "if-none-match": "*" } : { "if-match": etag }), - ...(args["feedback-match"] === undefined - ? {} - : { "if-feedback-match": String(args["feedback-match"]) }), -}; -const baseUrl = - typeof args["base-url"] === "string" - ? args["base-url"].replace(/\/+$/, "") - : "http://127.0.0.1:8788"; -const url = `${baseUrl}/api/docs/${encodeURIComponent(document)}`; -const payload = { - title, - content, - // Omitting collectionSlug leaves an existing document where it is. - ...(collection !== null ? { collectionSlug: collection } : {}), - ...(root ? { collectionSlug: null } : {}), -}; - -try { - const response = await fetch(url, { - method: "PUT", - headers, - body: JSON.stringify(payload), - }); - const responseText = await response.text(); - let body = null; - - if (responseText.length > 0) { - try { - body = JSON.parse(responseText); - } catch { - body = responseText; - } - } - - process.stdout.write( - `${JSON.stringify( - { - status: response.status, - etag: response.headers.get("etag"), - body, - }, - null, - 2, - )}\n`, - ); - - if (!response.ok) { - process.exitCode = 1; - } -} catch (error) { - fail(`Could not reach Pena: ${errorMessage(error)}`); -} - -function parseArgs(values) { - const parsed = {}; - - for (let index = 0; index < values.length; index += 1) { - const argument = values[index]; - - if (argument === "--help") { - parsed.help = true; - continue; - } - - if (argument === "--create") { - parsed.create = true; - continue; - } - - if (argument === "--root") { - parsed.root = true; - continue; - } - - if (!argument?.startsWith("--")) { - fail(`Unexpected argument: ${argument ??
