Emacs隐藏/显示支持C ++三斜杠Doxygen标记？

本文介绍了Emacs隐藏/显示支持C ++三斜杠Doxygen标记？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我使用Doxygen的三斜杠语法来标记我的C ++代码。有两个重要的情况出现： 1）块标记注释是线上唯一的元素，可能或可能不会开始向左冲例如， class foo ///一句简单的foo描述。详细说明可以 ///继续许多行。 { ... }; void foo :: bar ///一个句子简要描述吧。详细说明可以 ///继续许多行。 （）const { ... } 2）尾随的标记注释在第一行之前总是遵循一些C ++ 令牌，但仍可能溢出到后续行;例如 class foo { int _var1; ///< _var1的简要说明。 int _var2; ///< _var2 ///<需要额外的线路。 } void foo :: bar （int arg1 ///< arg1的简要说明，int arg2 ///< A brief描述arg2 ///<需要额外的行）const { ... } 我不知道处理这些约定存在什么隐藏/显示支持。 最重要的情况是块标记注释。理想情况下，我将想要完全消除这些，这意味着我将不想浪费一行只是为了表示存在折叠的块标记注释，喜欢边缘标记， a hideshowvis.el 。解决方案也许，作为部分答案，以下代码片段将会做到这一点。 按C ++中的M-s M-s模式，它隐藏了您所描述的所有评论。再次按M-s M-s再次显示评论。我知道短代码有其局限性： 如果可以分别隐藏/显示每个特殊注释，这将是很好的。 由于所有特别评论都被隐藏，所以您经常需要Ms Ms女士。因此， hs1-mode 应该在大型C ++文件上更有效（也许应该通过 jit-font-lock 连续一行的特殊评论应加入一个隐藏的块。 （defvar hs1-regexp \\（\ n [[：blank：]] * /// \\ | ///< \\）* $要隐藏的块的正则表达式列表） （define-minor-mode hs1-mode 隐藏/显示预定义的块：更轻hs1（如果hs1-mode let（ol）（save-excursion （goto-char（point-min））（while（search-forward-regexp hs1-regexp nil'noErr）当（eq（syntax-ppss-context（syntax-ppss（match-end 1）））'comment）（setq ol（make-overlay（match-beginning 0）（match-end 0）））（overlay-put ol'hs1 t）（overlay-put ol'invisible t））））） （remove-overlays（point-min）（point-max）'hs1 t））） （add-hook'c ++ - mode-hook'（lambda set-key（kbdMs Ms）'hs1-mode））） I use Doxygen's triple-slash syntax to markup my C++ code. There aretwo important cases which arise:1) block markup comments which are the sole element on the line and may or may not begin flush left; e.g.class foo/// A one sentence brief description of foo. The elaboration can/// continue on for many lines.{ ...};void foo::bar /// A one sentence brief description of bar. The elaboration can /// continue on for many lines. () const{ ...}2) trailing markup comments which always follow some number of C++ tokens earlier on the first line but may still spill over onto subsequent lines; e.g.class foo{ int _var1; ///< A brief description of _var1. int _var2; ///< A brief description of _var2 ///< requiring additional lines.}void foo::bar ( int arg1 ///< A brief description of arg1. , int arg2 ///< A brief description of arg2 ///< requiring additional lines. ) const{ ...}I wonder what hide/show support exists to deal with these conventions.The most important cases are the block markup comments. Ideally I wouldlike to be able to eliminate these altogether, meaning that I wouldprefer not to waste a line simply to indicate presence of a foldedblock markup comment, preferring a fringe marker, a la hideshowvis.el. 解决方案 Maybe, as a partial answer the following snippet of code would do the trick.Press M-s M-s in C++-mode and it hides all comments of the kind you described. Again pressing M-s M-s reveals the comments again. I know that the short code has its limitations:It would be nice if one could hide/show each special comment separately.Since all special comments are hidden you would need M-s M-s quite often. Therefore, hs1-mode should be more effective on large C++-files (maybe, it should be implmented via jit-font-lock).Consecutive lines of special comments should be joined to one hidden block.(defvar hs1-regexp "\\(\n[[:blank:]]*///\\|///<\\).*$" "List of regular expressions of blocks to be hidden.")(define-minor-mode hs1-mode "Hide/show predefined blocks." :lighter " hs1" (if hs1-mode (let (ol) (save-excursion (goto-char (point-min)) (while (search-forward-regexp hs1-regexp nil 'noErr) (when (eq (syntax-ppss-context (syntax-ppss (match-end 1))) 'comment) (setq ol (make-overlay (match-beginning 0) (match-end 0))) (overlay-put ol 'hs1 t) (overlay-put ol 'invisible t) )))) (remove-overlays (point-min) (point-max) 'hs1 t) ))(add-hook 'c++-mode-hook '(lambda () (local-set-key (kbd "M-s M-s") 'hs1-mode))) 这篇关于Emacs隐藏/显示支持C ++三斜杠Doxygen标记？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
