opencode-backslash-newline

Type \ and press Enter to get a newline in the prompt, the way Claude Code does it. In stock OpenCode, Enter submits, so that habit (or a keyboard macro built for Claude Code) sends your half-written message with a stray backslash at the end.

With the plugin, Enter checks the character right before the cursor. If it's a \, the backslash is removed and a newline goes in its place, wherever the cursor is in the prompt. Otherwise Enter submits as usual.

Emoji and other wide characters before the cursor are handled, so the check doesn't drift in long prompts.

Install

opencode plugin opencode-backslash-newline -g

That installs the package into your global OpenCode config and adds it to tui.json. Drop -g for the current project only. Restart OpenCode afterwards; plugins load at startup.

Without npm

mkdir -p ~/.config/opencode/tui-plugins
curl -fsSL https://raw.githubusercontent.com/moritzWa/opencode-backslash-newline/main/index.js \
  -o ~/.config/opencode/tui-plugins/backslash-newline.js

Then add it to ~/.config/opencode/tui.json:

{
  "plugin": ["./tui-plugins/backslash-newline.js"]
}

Keep it out of ~/.config/opencode/plugins/: files there are loaded as server plugins, and this one is TUI-only.
