Symbolic parser

[adeeconometrics]

Write a symbolic wrapper to get metadata about the object's content

Requirements

struct Symbol {
   std::string name;
  std::size_t value;
};

• Write a parse method
• Write simplify method
• Think about wrapping objects to symbols that are more ergonomic e.g. generative assignment to_symbol(object) -> symbol(name, value)

[adeeconometrics]

For now, settle with a dumb symbolic instance assignment

template <typename T, std::size_t Row, std::size_t Col> struct Symbol {

  Symbol() { m_counter++; }

  auto name() const noexcept -> std::string {
    return m_name + "_" + std::to_string(m_counter);
  }

private:
  static std::string m_name;
  static std::size_t m_counter;
};

template <typename T, std::size_t Rows, std::size_t Cols>
std::size_t Symbol<T, Rows, Cols>::m_counter = 0;

template <typename T, std::size_t Rows, std::size_t Cols>
std::string Symbol<T, Rows, Cols>::m_name = "x";

• Feature is put on hold. Expression optimization turns out to be more complicated than it seems.
• Sympp is a project that currently carries on the efforts of exploring expression-level simplifications
