Termit - The TERMinal edITor

npm i termit -g

Termit is a simple terminal editor somewhat inspired by Nano. It delivers the most basic text editing features like writing (obviously), cutting lines and uncutting or pasting lines.

Navigation includes arrow keys, page up and down, home and end on each line as well as start of document and end of document.

Running it from the terminal allows you to pass in a filepath argument which it will try to open. If it does not exist, it will try to create it on first save.

You can Save, Save As, Open, Save & Exit and Exit using keyboard shortcuts.

Keymap

Key	Action
Ctrl+S	Save
Ctrl+A	Save As
Ctrl+O	Open
Ctrl+X	Save & Exit
Ctrl+C	Exit

Embedding

The biggest feature of Termit is it's ability to be embedded inside your own terminal application.

// Include

/**
 * Setup with optional options
 * - disableOpen disables the ability
 *   for the user to open other files
 * - disableSaveAs disables the ability
 *   to save the content as another file
 *
 * These options are typically used for
 * embedded editors locked to a specific
 * file, similar to how visudo and jotr
 * works.

// before save. It uses the express-convention
// of using 'next()' to continue the chain.

    console.log(term.getText());

// If you don't want Termit to save to a file, only

// Using 'next' after unload is discouraged, but may
// function as you expect.
