Toolpaper

Convert a cURL PATCH request to Ruby

Paste any curl PATCH command and get clean Ruby code using net/http. Runs entirely in your browser — headers, auth, and JSON bodies map to idiomatic Ruby.

Quick answer

To convert a cURL command to Ruby, paste it into the Toolpaper workbench below. It parses the command in your browser and emits idiomatic Ruby code — headers, query string, request body, authentication (Bearer, Basic, API key), and cookies are all wired up automatically. No data is uploaded; conversion is fully client-side.

Example

A representative curl command for this scenario. Paste your own above to convert an exact match.

curl input
curl -X PATCH https://api.example.com/users/42 \
  -H "Content-Type: application/json" \
  -d '{"email":"ada@example.com"}'

Implementation notes

  • Request-line method (PATCH) and target URL are extracted from the curl command exactly as written — no case-folding, no path rewriting.
  • Every -H header maps to a Ruby header entry; duplicates are preserved so servers that read multi-valued headers keep behaving.
  • Query strings in the URL stay in the URL; -G with --data-urlencode is promoted to a structured params argument where net/http supports it.
  • Request bodies are parsed against Content-Type: JSON bodies use idiomatic serialization (net/http), form bodies use URL-encoding, multipart uses -F semantics with file@ handling.
  • TLS flags (--insecure, --cacert, --cert) surface as inline notes so you don't ship an insecure client to production by accident.

Common mistakes

  • Forgetting that -X PATCH without a body still sends an empty body — the generated code mirrors that exactly.
  • Assuming curl auto-follows redirects: it doesn't. Add -L (or the generator's follow-redirects flag) if you actually need to chase 3xx responses.
  • Copying a Cookie header from DevTools that already encodes session state — use the Clean panel to strip session cookies before you share.

Common questions

How do I send a PATCH request in Ruby?
Paste your curl PATCH command above. Toolpaper generates Ruby using net/http with headers, query string, and (where applicable) request body wired up.
Does the PATCH generator handle authentication?
Yes — Authorization headers, Bearer tokens, Basic auth (-u), and API keys pass through to the generated Ruby code unchanged.
Is my curl sent to a server?
No. Parsing and code generation run in your browser. Nothing is uploaded.
Can I also convert this to other languages?
Yes. Once you paste your command, the language picker lets you switch between 18 targets (fetch, axios, Python, Go, PHP, Ruby, Rust, Java, Kotlin, C#, PowerShell, Swift and more).
