The following is only relevant to users of Mark Kantrowitz's defsystem
The "Search Files" tool of MCL is really helpfull. However, as a user
of a DEFSYSTEM I would realy like to search systems and not directories
or single files. Mark Kantrowitz's defsystem supports the addition of
new system operations. Here's a first naive implementation:
(make::component-operation :search 'search-operation)
(make::component-operation 'search 'search-operation)
(defun SEARCH-OPERATION (Component Force) "
Every :file component will be called with this function.
Force is misused to hold the search string."
(with-tell-user ("Searching source" component :source)
(ccl::do-dialog-file-search (component-full-pathname Component :source) Force))
(defun GET-LIST-OF-SYSTEMS-FROM-USER () "
Prompts the user for systems, which it returns. "
#'(lambda (Name) (read-from-string (format nil ":~A" Name)))
(mapcar #'component-name (defined-systems))
:window-title "Select Systems:"
(defun SEARCH-SYSTEMS (String &optional (Systems (get-list-of-systems-from-user))) "
Search all files in <Systems> for <String>."
(dolist (System Systems)
(operate-on-system System :search :force String)))
Now here's the problem: ccl::do-dialog-file-search is not excately
what I need. The search works but..
(a) I don't like the side effects of ccl::do-dialog-file-search (beep if no
match, verbose ";searching ...") and
(b) since it can deal only with one pathname it creates a list dialog
box for every matching file in my system. I would prefer to have just
one list dialog box for ALL matching files. Are there any other handy
functions to search files for strings efficiently? ..something like:
FILE-CONTAINS-STRING-P (Pathname String)
Btw, here's a hack to add this functionality to the menu:
;;; insert "Search Systems" menu item after "Search Files"
(let* ((File-Menu (ccl:find-menu "Tools"))
(Search-File-Menu-Item (ccl:find-menu-item File-Menu "Search Files")))
(unless (ccl:find-menu-item File-Menu "Search Systems")
(let ((New-Items nil) (Old-Items (ccl:menu-items File-Menu)))
(apply #'ccl:remove-menu-items File-Menu (ccl:menu-items File-Menu))
(apply #'ccl:add-menu-items File-Menu
(dolist (Item Old-Items (reverse New-Items))
(push Item New-Items)
(when (equal Item Search-File-Menu-Item)
:menu-item-title "Search Systems"
#'(lambda () (ccl:eval-enqueue
(ccl:get-string-from-user "System Search String:")))))
