🏁 latis

(pronounced "lattice")

A command-line spreadsheet-style utility. Written in C++. Mostly a testing grounds for writing a parser in the parser-combinator style. (See /src/formula/....) Might eventually implement a TUI for opening and editing .latis files, performing spreadsheet computations, who knows.

Developing

Building locally

1. Install bazel.
2. Install ncurses-dev packages: sudo apt-get install libncurses5-dev libncursesw5-dev.
3. Make sure your .bazelrc contains build --cxxopt='-std=c++2a'.
4. From the repo root, run bazel build //src:latis.
5. Run bazel-bin/src/latis.

TODOS

• Need to implement latis::ui::Window and latis::ui::Pad such that they share a similar API, but Pad can be subaddressed with subrectangle coordinates
• Need to design latis::ui::Gridbox to handle printing multiple forms at locations without the border of a latis::ui::Textbox.
  • Should Gridbox hold unique_ptrs to other textboxes?
  • Should it hold the set of callbacks?
  • Can we decompose the grid into broad sections to avoid the number of widgets which need to handle bubble-style calls?
• Broadly: need to figure out how to test methods related to ncurses. Even printing a total screen dump and asserting text contents would be helpful.
  • Can ncurses and gtest be compiled together?
• Should I be pulling out all ncurses-specific wrappers into a library further for future generalziation?
  • To that end: I don't think anything under latis::ui::* is really Ssheet- or Latis- aware. Maybe it should be a totally separate src tree.
