$$\micro\text{cell}$$

Project inspired by Tsodings minicel project (video) - I saw only first 10 minutes but it looks cool

how to use

$\micro\text{cell}$ procesess input file in this format:

1       |  2              |  =A0*3
=B1+42  |  =sin(C0*pi/2)  |  15.6

Columns are A-Z and rows 0-99. Pipe (|) symbol is used to separate cells and white spaces are ignored. To create expression you use = followed by mathematical expression which can use basic math operations (+, -, *, /, ^), values of other cells, functions (sin, cos, sqrt, ceil, floor, log) or contants (pi, e).

Use make to build the program and ./ucel <input-file> to evaluate given file. Result of example above:

   |       A       |       B       |       C       |
----------------------------------------------------
 0 |     1.000     |     2.000     |     3.000     |
 1 |    41.000     |    -1.000     |    15.600     |

files

• main.c - $\micro\text{cell}$ <3
• /adt - data structures
  • list - simple implementation of list
  • stack - simple implementation of stack
• /eval - all files needed to evaluate math expression
  • tokenizer - splits string into tokens
  • substitute - replaces constants with actual values
  • analyzer - fixes negative numbers, operators before paretheses etc.
  • eval - evaluates expression by converting it to postfix notation and uses Shunting yard algorithm to evaluate it
• /ucel - $\micro\text{cell}$ stuff
  • ucel - parsing table and evaluating cells in right order
  • utils - printing utils
