如何跟踪给定主题的较新C ++ std文档？

Question

以下是C ++ std文档。文档号为N3721，取代了较早的N3634。

显然，很容易跟踪给定主题的旧文档。

但是，我的问题是：

如何跟踪给定主题的新文档？

例如，如果N3721被较新的文档取代，如何跟踪较新的文档？

Answer 1

对于较新的提案（以字母public class MoviesFragment extends BaseFragment implements SwipeRefreshLayout.OnRefreshListener, RecyclerItemClickSupport.OnItemClickListener { private static final String ARG_FRAG_TYPE = "fragType"; private static final String ARG_FRAG_TWO_PANE = "twoPane"; public enum Type { POPULAR, TOP_RATED, FAVORITES } @State ArrayList<Movie> movies; @State Type fragType; @State boolean twoPane; @BindView(R.id.refresh) SwipeRefreshLayout refreshView; @BindView(R.id.movies) RecyclerView moviesView; public static MoviesFragment newInstance(Type fragType, boolean twoPane) { MoviesFragment fragment = new MoviesFragment(); Bundle args = new Bundle(); args.putSerializable(ARG_FRAG_TYPE, fragType); args.putBoolean(ARG_FRAG_TWO_PANE, twoPane); fragment.setArguments(args); return fragment; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Icepick.restoreInstanceState(this, savedInstanceState); if (getArguments() != null) { fragType = (Type) getArguments().getSerializable(ARG_FRAG_TYPE); twoPane = getArguments().getBoolean(ARG_FRAG_TWO_PANE); } } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_movies_list, container, false); unbinder = ButterKnife.bind(this, rootView); init(); return rootView; } @Override public void onStart() { super.onStart(); EventBus.getDefault().register(this); } @Override public void onStop() { EventBus.getDefault().unregister(this); super.onStop(); } @Override public void onRefresh() { movies = null; updateMovies(); } @Override public void onItemClicked(RecyclerView recyclerView, int position, View v) { showMovieAtPosition(position); } @Subscribe(sticky = true) public void onEvent(UpdateFavoritesEvent event) { if (fragType == Type.FAVORITES) { EventBus.getDefault().removeStickyEvent(UpdateFavoritesEvent.class); onRefresh(); } } @Subscribe(sticky = true) public void onEvent(TwoPaneEvent event) { twoPane = event.twoPane; } @Override protected void init() { RecyclerItemClickSupport.addTo(moviesView) .setOnItemClickListener(this); moviesView.setLayoutManager(new GridLayoutManager(getContext(), 2)); moviesView.setHasFixedSize(true); refreshView.setOnRefreshListener(this); updateMovies(); } private void updateMovies() { if (movies == null) { MoviesCallback callback = new MoviesCallback() { @Override public void success(List<Movie> result) { movies = new ArrayList<>(result); if (moviesView != null) { moviesView.setAdapter(new MoviesAdapter(getContext(), movies)); } refreshView.setRefreshing(false); } @Override public void error(Exception error) { Toast.makeText(getContext(), error.getMessage(), Toast.LENGTH_SHORT).show(); error.printStackTrace(); refreshView.setRefreshing(false); } }; switch (fragType) { case POPULAR: MoviesUtil.getPopularMovies(getActivity(), callback); break; case TOP_RATED: MoviesUtil.getTopRatedMovies(getActivity(), callback); break; case FAVORITES: MoviesUtil.getFavoritesMovies(getActivity(), callback); break; } } else if (moviesView != null) { moviesView.setAdapter(new MoviesAdapter(getContext(), movies)); refreshView.setRefreshing(false); } } private void showMovieAtPosition(int position) { if (movies != null && position <= movies.size() - 1) { Movie movie = movies.get(position); EventBus.getDefault().postSticky(new ShowMovieEvent(movie)); if (twoPane) { getFragmentManager().beginTransaction() .replace(R.id.movie_detail, new MovieFragment()) .commit(); } else { startActivity(new Intent(getContext(), MovieActivity.class)); } } } }开头的提案），您可以使用wg21.link redirect service获取最新文档：

P

例如对于wg21.link - WG21 redirect service. Usage: wg21.link/nXXXX wg21.link/pXXXXrX Get paper. wg21.link/pXXXX Get latest public revision of paper. wg21.link/std wg21.link/std{11,14,17} Get working draft. wg21.link/cwgXXX wg21.link/ewgXXX wg21.link/lwgXXX wg21.link/lewgXXX wg21.link/fsXXX wg21.link/editXXX Get issue. wg21.link/pXXXX/issue Get issue for paper. wg21.link/*wgXXX/paper Get paper for issue. wg21.link/index.json wg21.link/index.ndjson wg21.link/index.txt wg21.link/specref.json Get everything. wg21.link/ Get usage. wg21.link/<something else> Get 404. If you're Slackbot or Twitterbot: Get OpenGraph metadata instead. ，如果我们使用wg21.link/P0476，我们将获得最新版本P0476R2。

在对How does the standards committee indicate the status of a paper under consideration?的答复中，我将详细介绍WG21网站以及在该网站上可以找到哪些文档。

将所有内容链接用于Pre P提案

如果我们使用wg21 redirect service Get Everything link，我们可以对论文标题进行文本搜索。因此，对于您的示例P0476: Bit-casting object representations，我们可以看到最后一个文档是N3857：

  

“ N3857”：{
          “ type”：“ paper”，
          “ title”：“对std :: future和相关API的改进”，
          “ subgroup”：“并发”，
          “作者”：“ N。Gustafsson，A。Laksberg，H。Sutter和S. Mithani”，
          “ long_link”：“ http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3857.pdf”，
