Inspect is a very simple spreadsheet application.
This project is essentially experimental code - I wrote it while learning how to use Ragel and Lemon to build a parser. The build system was hacked together pretty quickly so that it would work on Mac. It should compile cleanly on Linux systems, but I have not tested this recently.
Build dependencies (these can be installed using a package manager such as 'apt' or 'brew'):
Vendored:
- googletest (for unit tests only, included in 'vendor' directory)
Inspect can be built using CMake. The recommended approach is to create a build directory, and to run 'cmake' from there. For example:
mkdir build
cd build
cmake ..
make
For Windows... you're on your own.
This project includes a miniature REPL (inspect_console) for interacting with a sheet. A sheet is really just a collection of cells that can be identified using typical spreadsheet addresses (e.g. A1, B2, C12, etc).
If you followed the build instructions above, you can start the REPL using:
./inspect_console
You'll be greeted with a > prompt, where you can assign formulas to cells. After each assignment, the current state of the sheet will be printed out, e.g.:
> A1 = 1
[1,1]: 1
> A2 = A1
[1,1]: 1
[1,2]: 1
> B3 = A2 * 2
[1,1]: 1
[1,2]: 1
[2,3]: 2
> B4 = B3 + A1 * 2
[1,1]: 1
[1,2]: 1
[2,3]: 2
[2,4]: 4
>
You can force the parser to treat a formula as a literal value, using an apostrophe ' instead of equals =:
> A1 'This is my literal
[1,1]: This is my literal
>
And you can inspect the formula and value of an individual cell:
> A1 = 2
[1,1]: 2
> A2 = A1 + 1
[1,1]: 2
[1,2]: 3
> A2
A2 = A1 + 1 = 3
>
The REPL will tell you if your input is invalid:
> Some invalid input
Error: Invalid input.
