Member Data Documentation

rem

substr c4::yml::LineContents::rem

current line remainder, without newline characters

Definition at line 58 of file parser_state.hpp.

full

substr c4::yml::LineContents::full

full line, including newline characters \n and \r

Definition at line 59 of file parser_state.hpp.

num_cols

size_t c4::yml::LineContents::num_cols

number of columns in the line, excluding newline characters (ie the initial size of rem)

Definition at line 60 of file parser_state.hpp.

indentation

size_t c4::yml::LineContents::indentation

number of spaces on the beginning of the line. TODO this should not be a member of this object. We only care about indentation in block mode, so this should be moved to the parser state.

Definition at line 62 of file parser_state.hpp.
