The Cac Language

CacTui includes a domain-specific language called Cac Language for running Excel-like expressions. This language allows you to perform calculations directly within cells using familiar syntax.

Examples

• Basic Arithmetic: =A1 + B2
• Functions: =SUM(A1:A10)
• Conditional Expressions: =IF(A1 > 10, "High", "Low")
• Range: =A1:A10, get values from A1 to A10

The Cac Language supports a variety of functions and operations, making it a powerful tool for data manipulation and analysis within the terminal.

• Normal Mode: Default mode for navigation.
• Insert Mode: Mode for editing cell values.
• Visual Mode: Mode for selecting multiple cells.
• Command Mode: Mode for executing commands.
• Exit Mode: Mode to exit the application.

Key Bindings

• h, j, k, l: Move left, down, up, and right respectively.
• i: Enter Insert mode.
• v: Enter Visual mode.
• :: Enter Command mode.
