emitrs_yaml() [1/9]

template<class CharOwningContainer >

substr c4::yml::emitrs_yaml	(	Tree const &	t,
		id_type	id,
		EmitOptions const &	opts,
		CharOwningContainer *	cont,
		bool	append = false
	)

(1) emit+resize: emit YAML to the given std::string/std::vector-like container, resizing it as needed to fit the emitted YAML.

If append is set to true, the emitted YAML is appended at the end of the container.

Returns

a substr trimmed to the emitted YAML (excluding the initial contents, when appending)

Definition at line 765 of file emit.hpp.

{
    size_t startpos = append ? cont->size() : 0u;
    cont->resize(cont->capacity()); // otherwise the first emit would be certain to fail
    substr buf = to_substr(*cont).sub(startpos);
    substr ret = emit_yaml(t, id, opts, buf, /*error_on_excess*/false);
    if(ret.str == nullptr && ret.len > 0)
    {
        cont->resize(startpos + ret.len);
        buf = to_substr(*cont).sub(startpos);
        ret = emit_yaml(t, id, opts, buf, /*error_on_excess*/true);
    }
