modulefdoc_decl

Reading declarations and procedure headers from the text of a statement.

Everything here runs inside the parallel parsing loop, so it does not call functions returning deferred-length strings (see example/slen_race.f90).

subroutine original_prefix(line, low, n, attribs, text)

Set text to line(1:n) with the words of attribs removed, keeping the case of what is left.

subroutine parse_declarator(text, name, dimension, initial, points)

Read one name of a declaration, such as x(3) = 1.

subroutine parse_procedure_header(line, h)

subroutine split_attributes(rest, attributes, names)
