Terminal renderer

The terminal renderer (datamaker-form) is a TUI client: point it at a .dmf (file or URL), fill the form in your terminal, and it seals + submits — the same end-to-end-encrypted path as every other client. It’s a self-contained, single-file binary with no runtime to install, so it’s handy for SSH sessions, scripts, and headless boxes where a browser isn’t an option.

Download

Grab the binary for your platform from the GitHub Releases page:

Platform	Asset
macOS (Apple Silicon)	datamaker-form-osx-arm64
macOS (Intel)	datamaker-form-osx-x64
Linux (x86-64)	datamaker-form-linux-x64
Linux (ARM64)	datamaker-form-linux-arm64
Windows (x64)	datamaker-form-win-x64.exe

On macOS/Linux, make it executable (and optionally drop it on your PATH):

chmod +x datamaker-form-osx-arm64
mv datamaker-form-osx-arm64 /usr/local/bin/datamaker-form

Tip

First launch on macOS may be blocked by Gatekeeper — clear the quarantine flag with xattr -d com.apple.quarantine datamaker-form (or right-click → Open once).

Run

datamaker-form ./contact.dmf
datamaker-form https://example.com/forms/contact.dmf

On launch it:

1. Loads + verifies the bundle (Ed25519 signature + hashes).
2. Shows a trust-on-first-use prompt with the signer’s fingerprint and identity (and whether it’s FOBO-attested), so you can eyeball a new signer before trusting them.
3. If the form’s policy is Authenticated, runs an OAuth sign-in.
4. Renders the fields; on submit, seals the values against the form’s recipient public key and POSTs to the submissions endpoint.

Options

Flag	Purpose
<path-or-url>	the .dmf to fill (positional)
--submit-endpoint <url>	override the submissions API base
--trust <fingerprint>	pre-trust a signer fingerprint (skips the TOFU prompt)
--template, -t <name>	terminal color template: dark, green, or light
--help, -h	show usage

The submit path uses the .NET SDK (DataMakerClient) under the hood, so the terminal ships only the client subset — no signing/keygen code.

Build from source

Prefer to build it yourself? A self-contained single-file binary is produced per platform (osx-arm64, osx-x64, linux-x64, linux-arm64, win-x64), no runtime required:

dotnet publish DataMaker.Forms.Renderer.Terminal/DataMaker.Forms.Renderer.Terminal.csproj \
  -c Release -r osx-arm64 --self-contained -o out
# -> out/datamaker-form

Swap -r for your target runtime identifier. The published Releases are built the same way, one per RID.
