iterm2-size v0.0.1

iterm2-size

Get the size of the current iTerm2 window, in pixels. This might be useful for resizing images to fit, for example.

This library works ONLY if:

• You are on MacOS.
• You are using a relatively-modern version of iTerm2 that supports the Report Cell Size escape code.
• iTerm2 is the controlling terminal for your process.

This will work even if stdin or stdout is redirected to/from a file or piped to/from another process, which is why it was worth pulling this function out into a separate library.

Installation

npm install iterm2-size

API

Full API documentation is available.

Example:

import {getTerminalSize} from 'iterm2-size';

// Pass in rows/columns adjustments, if desired, to account for prompt height.
const {width, height} = await getTerminalSize({rows: -2});
console.error(`${width}x${height}`);

Testing

This library is difficult to test on GitHub actions, since GHA doesn't run iTerm2. CI just checks that eslint and typescript are happy.
