语义,放弃如何强制解析源文件

Semantic, cedet how to force parsing of source files

本文关键字:源文件 何强制 放弃 语义      更新时间:2023-10-16

我一直在我的emacs c/c++开发设置中尝试cedet和语义,除了一个小细节外,我对它很满意。

我使用ede-cpp-root-project创建一个项目,并给出我的项目的根目录以及包含文件所在的目录,如下所示:

(ede-cpp-root-project "My Project"
                :name "My Project"
                :file "/path/to/rootdir/AFILE"
                :include-path '( 
                "/include2"
                "/include1"
                               )
                )

这使我可以很容易地跳转到具有semantic-ia-fast-jump的函数的声明,但它并不能让我了解这些函数的定义。所以它似乎只处理头文件,而完全忽略源文件。即使我继续声明函数并触发semantic-analyze-proto-impl-toggle,它也会告诉我找不到合适的实现。

如果我手动打开函数实现所在的源文件,那么只有在那时,它才会被语义解析,上面提到的所有函数都能工作。

所以我的问题是,除了手动打开项目根目录下的所有源文件,或者通过:spp-files参数手动将它们包含在ede-cpp-root-project中之外,还有其他方法可以强制解析目录下的全部源文件吗?

谢谢!

在长期忽视这个问题后,我认为我应该花一些时间阅读elisp,并尝试找出解决方案。这不是最漂亮的elisp代码,因为我使用elisp只是为了满足我的emacs需求,但它满足了我的需求。

(defvar c-files-regex ".*\.\(c\|cpp\|h\|hpp\)"
  "A regular expression to match any c/c++ related files under a directory")
(defun my-semantic-parse-dir (root regex)
  "
   This function is an attempt of mine to force semantic to
   parse all source files under a root directory. Arguments:
   -- root: The full path to the root directory
   -- regex: A regular expression against which to match all files in the directory
  "
  (let (
        ;;make sure that root has a trailing slash and is a dir
        (root (file-name-as-directory root))
        (files (directory-files root t ))
       )
    ;; remove current dir and parent dir from list
    (setq files (delete (format "%s." root) files))
    (setq files (delete (format "%s.." root) files))
    (while files
      (setq file (pop files))
      (if (not(file-accessible-directory-p file))
          ;;if it's a file that matches the regex we seek
          (progn (when (string-match-p regex file)
               (save-excursion
                 (semanticdb-file-table-object file))
           ))
          ;;else if it's a directory
          (my-semantic-parse-dir file regex)
      )
     )
  )
)
(defun my-semantic-parse-current-dir (regex)
  "
   Parses all files under the current directory matching regex
  "
  (my-semantic-parse-dir (file-name-directory(buffer-file-name)) regex)
)
(defun lk-parse-curdir-c ()
  "
   Parses all the c/c++ related files under the current directory
   and inputs their data into semantic
  "
  (interactive)
  (my-semantic-parse-current-dir c-files-regex)
)
(defun lk-parse-dir-c (dir)
  "Prompts the user for a directory and parses all c/c++ related files
   under the directory
  "
  (interactive (list (read-directory-name "Provide the directory to search in:")))
  (my-semantic-parse-dir (expand-file-name dir) c-files-regex)
)
(provide 'lk-file-search)

要使用它,可以像这样直接调用函数:(my-semantic-parse-dir "path/to/dir/root/" ".*regex"),也可以从缓冲区按M-x lk-parse-curdir-c,递归地扫描该buferr访问文件名目录中所有与c/c++相关的文件。

调用函数的另一种可能也是更可取的方法是交互调用lk-parse-dir-c,这反过来会提示您要解析的目录。

如果任何一位elisp大师有更好的解决方案或建议来改进代码,我很乐意听取他们的意见。

我最近为Python实现了这一点。它可以用于C/C++,只需做一些小的更改。

(defvar python-extention-list (list "py"))
(defun semanticdb-rescan-directory (pathname)
  (dolist (file (cddr (directory-files pathname t)))
    (if (file-directory-p file)
        (semanticdb-rescan-directory file)
      (when (member (file-name-extension file) python-extention-list)
        (message "Parsing %s file." file)
        (ignore-errors
            (semanticdb-file-table-object file))))))
(defun semantic-python-rescan-includes ()
  (interactive)
  (dolist (includes (semantic-python-get-system-include-path))
    (message "Parsing %s" includes)
    (semanticdb-rescan-directory includes)))

尝试运行命令"bovate"。这可以通过组合键Meta+X来完成,然后键入"bovate",然后按"Enter"键。在窗口中,"Meta"键被称为"Alt"键。
