This project implements the 7 tasks of the 7GUIs (https://7guis.github.io/7guis/) in OCaml with the library LablGtk3 (an object oriented Gtk3 binding). The CalendarLib package is used to for dates handling.
The 7th task (Cells) handles float arithmetics (+, -, *, /) including unary
operators, and the SUM function. Circular references are detected. It is
composed of multiple files. cells.ml the main program which supports the
GUIs aspects, expr.ml an abstract spreadsheet. parser.mly the parser
description (with menhir), lexer.mll the lexer description (with ocamllex).
The different tasks are compiled and executed with:
dune exec ./counter.exe
dune exec ./temperature.exe
dune exec ./flightbooker.exe
dune exec ./timer.exe
dune exec ./crud.exe
dune exec ./circledrawer.exe
dune exec ./circledrawer2.exe
dune exec ./cells.exe
LablGtk3 is an object oriented binding to Gtk3. However, some functional traits are involved. (Callback)
A circledrawer alternative is proposed which uses only a functional (immuable) structure (list) instead of Hashtbl and makes undo/redo easier. This saves a few lines.
