Calculator that I Love O' so very much

Why C?

Honestly? I enjoy programming in C and the high performance is always a bonus.

The lower level of C always forces me to better structure my projects. I am generally far more proud of my C code compared to my Python code.

The original idea for this project was implemented in Python. I may go back to this project in the future to prototype ideas quickly. But you can safely assume that cilo will be more reliable going forwards.

Dependecies

None.

(Though your terminal must support Unicode and ANSI escape codes)

Building

Linux

Clone the repository, go into the directory, type make and Bob’s your uncle.

git clone https://github.com/timeopochin/cilo.git
cd cilo
make

macOS

Probably the same or whatever, I don’t know, I don’t use macOS.

Windows

I would recomend this tutorial with detailed instructions on how to setup your build environment.

Usage

Right now, I have only implemented the 'pretty' rendering, any interactive UI and actual evaluation of the equations are, for the time being, only (partially) working on the Python project.

After building, various (only 1 for now) executables will be in the bin directory. These can be executed or placed in a directory contained in your PATH to be accessible from anywhere. It’d be cool for me to add a make install, but I’m lazy and far from fluent in Makefile standards.

Prettify

prettify takes string arguments in Reverse Polish Notation (RPN) and displays a nicely formated equation.

You can set the backgroup and foregroud colours of following equations with -bg <colour> and -fg <colour>.

You can use special functions in the RPN arguments:

• n to negate

• s, c and t for sin, cos and tan respectively

• h to highlight a section

Here are some examples you can try:

prettify '3 1 2 / +'

prettify -bg magenta -fg black '5 3 + 4 1 / s *' -bg blue '5 4 2 + h / 3 n 2 ^ / 1 6 * /'
