In termr: Modern Reactive Terminal Applications with Data Workflows

termr: modern reactive terminal applications for R

Description

Build modern terminal applications with first-class support for data workflows: composable widgets and layouts, reactive state, events, keyboard and mouse input, themes, and background R workers.

Details

A virtual framebuffer and incremental rendering send changed cells to the terminal. test_app() drives the same event loop and renderer headlessly. data_table() and data_browser() support data inspection; table_source() adds lazy paging. Optional DBI integrations provide SQL and database workflows, and render_text(), render_html() and related helpers export static output without a terminal.

Start with app(), the widget constructors (vertical(), horizontal(), label(), button(), input()) and run(). Advanced applications can use signal(), run_worker(), sql_editor() and db_explorer(). These APIs, lazy sources, static export and custom extensions remain experimental; see the repository's API stability guide for the complete classification.
