Cell

A terminal based spreadsheet program built in Rust.

Background

This is my first time using Rust, and I thought a terminal spreadsheet program would be a great project to get started with. This was only intended to be a toy spreadsheet, but it should be able to read/write arbitrary CSV files and do simple math.

The Rust by Example book was a very helpful resource along the way.

Controls

The app is split into Nav mode and Edit mode.

When in Nav mode:

• Press q to exit the program
• Press ctrl+s to save the file (then type in a file name and press enter)
• Use the arrow keys to move around
• Press = to start editing a cell (see Edit mode controls below)
• Press Backspace to clear a cell
• Use wasd to scroll the viewport
• Press ctrl+z to undo
• Press ctrl+y to redo

When in Edit mode:

• Press enter to finish editing the cell
• Press escape to abort your changes
• Use left-arrow and right-arrow to move the cursor

Feature List
