download

Download a file from a URL (wget-like)

Input: HTTP

Arg	Description
`out`	Output filename (defaults to the last path segment of the URL)

Download a file from a URL and save it to disk (wget-like).

Usage

fimod s -i https://example.com/file.tar.gz -m @download

With a custom output filename:

fimod s -i https://example.com/file.tar.gz -m @download --arg out=myfile.tar.gz

Args

Arg	Required	Description
`out`	No	Output filename — defaults to the last path segment of the URL

Example

fimod s -i https://github.com/cli/cli/releases/download/v2.45.0/gh_2.45.0_linux_amd64.tar.gz \
  -m @download --arg out=gh.tar.gz
# → writes gh.tar.gz in the current directory

Chaining with @gh_latest

The natural companion to @download is @gh_latest — resolve the latest release URL, then download it in one pipeline:

# Get the latest release URL and download it
fimod s -i https://github.com/sinelaw/fresh/releases/latest \
  -m @gh_latest \
  --arg repo="sinelaw/fresh" \
  --arg asset='fresh-editor_{version}-1_amd64.deb' \
  | fimod s -I - -m @download --arg out=fresh-editor.deb

How it works

The mold uses input-format=http to get the raw HTTP response body as bytes, then calls set_output_format("raw") and set_output_file(filename) to write the binary content directly to disk — bypassing JSON serialization entirely.

Filename resolution order

--arg out=... if provided
Content-Disposition header filename (auto-detected from the HTTP response)
Last path segment of the URL (stripped of query params)

Error handling

HTTP responses with status ≥ 400 abort with gk_fail instead of writing an error page to disk.

Mold directives

input-format=http — expose the raw HTTP response (status, headers, body bytes)
