[英]How to load cedet, semantic et. al only when .cxx,.h .cpp files are open
[英]Semantic, cedet how to force parsing of source files
我在我的emacs c / c ++开发设置中一直在尝试使用cedet和semantic,除了一个小细节之外我对它非常满意。
我使用ede-cpp-root-project
来创建一个项目,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"
)
)
这使我可以使用semantic-ia-fast-jump
轻松跳转到函数的声明,但它不能让我了解这些函数的定义。 因此它似乎只处理头文件并完全忽略源文件。 即使我继续声明该函数并触发semantic-analyze-proto-impl-toggle
它也会告诉我没有找到合适的实现。
如果我手动打开函数实现所在的源文件,那么它只能通过语义进行解析,并且所有上述函数都能正常工作。
所以我的问题是,没有手动打开项目根目录下包含的所有源文件,或者通过:spp-files
参数手动将它们包含在ede-cpp-root-project
,还有其他任何方法可以强制解析所有源文件一个目录?
谢谢!
在忽略了这个问题很长一段时间后,我以为我应该花一些时间阅读elisp,并尝试找出解决方法。 它不是最漂亮的elisp代码,因为我只使用elisp来满足我的emacs需求,但它可以满足我的需求。
(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,请直接调用函数:( (my-semantic-parse-dir "path/to/dir/root/" ".*regex")
Mx lk-parse-curdir-c
(my-semantic-parse-dir "path/to/dir/root/" ".*regex")
或者从缓冲区按Mx lk-parse-curdir-c
递归从该buferr的访问文件名目录中扫描所有与c / c ++相关的文件。
调用函数的另一种可能的优选方法是通过交互方式调用lk-parse-dir-c
,这反过来会提示您解析一个目录。
如果任何elisp guru有更好的解决方案或改进代码的建议,我很乐意听到它们。
我最近为Python实现了这个。 它可以用于C / C ++,只需稍作修改即可。
(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“bovinate”。 这可以使用组合键Meta + X完成,然后键入“bovinate”,然后按“Enter”键。 “Meta”键在windows中称为“Alt”键。
