- [#source_position]
- [section source_position]
- [h1 Synopsis]
- template <class Line, class Col, class PrevChar>
- struct source_position;
- This is a [link metaprogramming_value template metaprogramming value].
- [table Arguments
- [[Name] [Type]]
- [[`Line`] [[link boxed_value boxed] integer value]]
- [[`Col`] [[link boxed_value boxed] integer value]]
- [[`PrevChar`] [[link boxed_value boxed] character value]]
- ]
- [h1 Description]
- Compile-time data-structure describing a position of the input text.
- The values of this data-structure store the last character that was parsed
- before reaching the position of the input described by the `source_position`
- value.
- Its tag is [link source_position_tag `source_position_tag`].
- The beginning of the input text is represented by [link start `start`].
- [h1 Header]
- #include <boost/metaparse/source_position.hpp>
- [h1 Expression semantics]
- For any `l`, `c` compile-time boxed integral values and `p` compile-time boxed
- character value, the following are equivalent
- get_col<source_position<l, c, p>>::type
- c::type
- get_line<source_position<l, c, p>>::type
- l::type
- get_prev_char<source_position<l, c, p>>::type
- p::type
- [h1 Constant values of this type]
