Meet Nebu, a user-friendly spreadsheet editor designed for Varvara’s system that handles csv/tsv files. It simplifies calculations by allowing users to specify cell ranges and perform math operations like addition (+), subtraction (-), multiplication (*), division (/) on them. The range format uses colons between two cell identifiers, ensuring each cell performs only one operation at a time without recursive self-inclusion.
Besides basic arithmetic operators, Nebu offers special functions such as ‘#’ to count non-empty cells in a given range and ‘”‘ for string concatenation when no operator is specified; it defaults to summing values. With its instantaneous launching speed and lightweight nature—even lighter than an empty Excel file—Nebu proves efficient yet powerful for managing data spreads.
The source code resides in Uxntal’s format (`.tal`), while dependencies like Fix32 Library from the same ecosystem aid its functionality. Overall, Nebu presents a practical solution for those seeking an accessible way to manipulate and analyze tabular information within Varvara systems.\
