⚠️ WORK IN PROGRESS – This project is incomplete and not ready for general use.

An intuitive TUI (Terminal User Interface) spreadsheet written in Go and BubbleTea that leverages the powerful expression language Expr.

How to use

flags (on start)      -c <cols> -r <rows>
                      -vc <viewport cols> -vr <viewport rows>
                      -f <filename>

enter values          <enter> or <tab> then type numbers
enter labels          <enter> or <tab> then type letters
enter expression      <enter> or <tab> then type =expression
                      e.g. =min(A3:B5)
                      use any EXPR expression (see expr-lang.org)

move                  → ← ↑ ↓
edit                  <enter> or <tab>
                      <esc> to exit edit mode
copy                  ⌃c
copy value only       ⌃n
paste                 ⌃v

save                  ⌃s
quit                  ⌃q

TO DO

• implement functions not available in EXPR (such as prod, sum, avg)
• select ranges visually
• autosuggest formulae
• export as csv
• complete unit tests

DONE

• implement simple arithmetic (not just functions) // via expr language
• viewport and scrolling
• implement SUM, PRODUCT, AVERAGE, MIN, MAX, COUNT
• comma-separated ranges
• hilite references to selected cell
• undo / redo
• load file
• some unit tests
• round results to the most-precise of its operands
• filepath/filename for save
• flags -r (rows) -c (columns) -f (filename)
