Summary

im +messages-send's --content/--text/--markdown flags currently accept only inline values. These carry large JSON/Markdown payloads whose embedded double quotes get corrupted on Windows by the .cmd shim's %* forwarding (the .cmd wrapper re-parses " as a group delimiter, so --content fails with "not valid JSON"). This PR lets all three flags read from @file or - (stdin), consistent with the content-like flags in docs/calendar/drive.

Changes

  • Declare Input: []string{common.File, common.Stdin} on --content/--text/--markdown, reusing the framework's existing resolveInputFlags (BOM stripping, @@ escape, single-stdin guard).
  • Update help text to note (inline, @file, or - for stdin).
  • Add regression test TestMessagesSendContentFlagsAcceptFileAndStdin.

Test Plan

  • go test ./shortcuts/common/ -run TestResolveInputFlags — 15/15 PASS (existing framework coverage)
  • go test ./shortcuts/im/ -run TestMessagesSendContentFlagsAcceptFileAndStdin — PASS
  • Manual: --content @card.json and --content - (stdin pipe) read JSON correctly on Windows and send the card (previously required a Python subprocess workaround to bypass the .cmd quoting bug)

Summary by CodeRabbit

  • Documentation

    • Clarified that message content, text, and Markdown inputs support inline values, files, and standard input.
    • Documented automatic Markdown style optimization and image URL resolution.
  • Tests

    • Added coverage confirming the supported file and standard input options for message content flags.

Allow --content/--text/--markdown to read from @file or stdin (-), consistent with docs/calendar/drive content flags. Avoids shell-quoting corruption of large JSON/Markdown payloads, especially on Windows where the .cmd shim's %* forwarding breaks embedded double quotes.

Review Change Stack

📝 Walkthrough

Walkthrough

The message send command now documents inline, file, and stdin input for its content flags. Tests verify that the content, text, and markdown flags accept file and stdin sources. Markdown help also documents style optimization and image URL resolution.

The content, text, and markdown flags document inline, file, and stdin input. The markdown flag also documents style optimization and image URL resolution. Tests verify file and stdin input sources.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 15f81

The PR adds @file and stdin support for message content flags, but real CLI coverage for these paths is still missing, so regressions in input handling could reach users. The change is mergeable with explicit owner follow-up to add shortcut-level dry-run and live coverage.

Add shortcut-level dry-run and live coverage for file and stdin inputs.

ImMessagesSend has no CLI E2E coverage for @file or - on --content, --text, or --markdown. Existing live helpers cover only literal --text; the --file workflow covers a different media flag. Exercise the changed sources through the real CLI and keep the metadata assertion.
