C/C++ math formula viewer
Motivation
We can utilize useful mathematical functions in C/C++ by including math.h or cmath library. However, it is hard to recognize the full functionality of the function at a glance if the function call is deep and complex. The indirect function signature also reduces cognition. For example, it is hard to know the mathematical meaning of the following code:
log(sinf(atan2f(hypot(abs(a + b), abs(c)), d + f)).This is inefficient!! It will be better to show the functionality with common math formula form:
Therefore, I implemented the plugin in which the users can directly see the following formula, driven by the overlapped math function.
Features
Hovering math formula
Quite intuitive. First, write the c or c++ code with the functions & constants from c math libraries. And if you point the math function with the mouse, the plugin parses the function and its arguments recursively and hovers the generated Unicode-style math formula.
