[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 ++開發設置中一直在嘗試使用cedet和semantic,除了一個小細節之外我對它非常滿意。
我使用ede-cpp-root-project
來創建一個項目,並給出我的項目的根目錄以及包含文件所在的目錄,如下所示:
(ede-cpp-root-project "My Project"
:name "My Project"
:file "/path/to/rootdir/AFILE"
:include-path '(
"/include2"
"/include1"
)
)
這使我可以使用semantic-ia-fast-jump
輕松跳轉到函數的聲明,但它不能讓我了解這些函數的定義。 因此它似乎只處理頭文件並完全忽略源文件。 即使我繼續聲明該函數並觸發semantic-analyze-proto-impl-toggle
它也會告訴我沒有找到合適的實現。
如果我手動打開函數實現所在的源文件,那么它只能通過語義進行解析,並且所有上述函數都能正常工作。
所以我的問題是,沒有手動打開項目根目錄下包含的所有源文件,或者通過:spp-files
參數手動將它們包含在ede-cpp-root-project
,還有其他任何方法可以強制解析所有源文件一個目錄?
謝謝!
在忽略了這個問題很長一段時間后,我以為我應該花一些時間閱讀elisp,並嘗試找出解決方法。 它不是最漂亮的elisp代碼,因為我只使用elisp來滿足我的emacs需求,但它可以滿足我的需求。
(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,請直接調用函數:( (my-semantic-parse-dir "path/to/dir/root/" ".*regex")
Mx lk-parse-curdir-c
(my-semantic-parse-dir "path/to/dir/root/" ".*regex")
或者從緩沖區按Mx lk-parse-curdir-c
遞歸從該buferr的訪問文件名目錄中掃描所有與c / c ++相關的文件。
調用函數的另一種可能的優選方法是通過交互方式調用lk-parse-dir-c
,這反過來會提示您解析一個目錄。
如果任何elisp guru有更好的解決方案或改進代碼的建議,我很樂意聽到它們。
我最近為Python實現了這個。 它可以用於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)))
嘗試運行命令“bovinate”。 這可以使用組合鍵Meta + X完成,然后鍵入“bovinate”,然后按“Enter”鍵。 “Meta”鍵在windows中稱為“Alt”鍵。
