;;; Commentary:
;; This program provides methods to find file in project.
;; - Only dependency is BSD/GNU find
;; - Works on Windows with minimum setup
;; - Works on Tramp Mode (https://www.emacswiki.org/emacs/TrampMode)
;; - fd (faster alternative of find, see https://github.com/sharkdp/fd) is supported
;;
;; Usage,
;; - You can insert "(setq ffip-use-rust-fd t)" into ".emacs" to use fd (alternative of find)
;; - `find-file-in-project-at-point' guess the file path at point and
;; find file
;; - `find-file-in-project-by-selected' uses the selected region
;; as the keyword to search file. You can provide the keyword
;; if no region is selected.
;; - `find-directory-in-project-by-selected' uses the select region
;; to find directory. You can provide the keyword if no region
;; is selected.
;; - `find-file-in-project' starts search file immediately
;; - `ffip-create-project-file' creates ".dir-locals.el"
;; - `ffip-lisp-find-file-in-project' finds file in project.
;; If its parameter is not nil, it find directory.
;;
;; A project is found by searching up the directory tree until a file
;; is found that matches `ffip-project-file'.
;; You can set `ffip-project-root-function' to provide an alternate
;; function to search for the project root. By default, it looks only
;; for files whose names match `ffip-patterns',
;; If you have so many files that it becomes unwieldy, you can set
;; `ffip-find-options' to a string which will be passed to the `find'
;; invocation in order to exclude irrelevant subdirectories/files.
;; For instance, in a Ruby on Rails project, you are interested in all
;; .rb files that don't exist in the "vendor" directory. In that case
;; you could set `ffip-find-options' to "-not -regex \".*vendor.*\"".
;; `ffip-insert-file' insert file content into current buffer.
;; `find-file-with-similar-name' find file with similar name to current
;; opened file. The regular expression `ffip-strip-file-name-regex' is
;; also used by `find-file-with-similar-name'.
;;
;; all these variables may be overridden on a per-directory basis in
;; your ".dir-locals.el". See (info "(Emacs) Directory Variables") for
;; details.
;;
;; Sample ".dir-locals.el",
;;
;; ((nil . ((ffip-project-root . "~/projs/PROJECT_DIR")
;; ;; ignore files bigger than 64k and directory "dist/" when searching
;; (ffip-find-options . "-not -size +64k -not -iwholename '*/dist/*'")
;; ;; only search files with following extensions
;; (ffip-patterns . ("*.html" "*.js" "*.css" "*.java" "*.xml" "*.js"))
;; (eval . (progn
;; (require 'find-file-in-project)
;; ;; ignore directory ".tox/" when searching
;; (setq ffip-prune-patterns `("*/.tox" ,@ffip-prune-patterns))
;; ignore BMP image file
;; (setq ffip-ignore-filenames `("*.bmp" ,@ffip-ignore-filenames))
;; ;; Do NOT ignore directory "bin/" when searching
;; (setq ffip-prune-patterns `(delete "*/bin" ,@ffip-prune-patterns))))
;; )))
;;
;; To find in current directory, use `find-file-in-current-directory'
;; and `find-file-in-current-directory-by-selected'.
;;
;; `ffip-split-window-horizontally' and `ffip-split-window-vertically' find&open file
;; in split window.
;; `ffip-show-diff' execute the backend from `ffip-diff-backends'.
;; The output is in Unified Diff Format and inserted into *ffip-diff* buffer.
;; Press "o" or "C-c C-c" or "ENTER" or `M-x ffip-diff-find-file' in the
;; buffer to open corresponding file.
;;
;; `ffip-diff-find-file-before-hook' is called before `ffip-diff-find-file'.
;;
;; `ffip-diff-apply-hunk' applies current hunk in `diff-mode' (please note
;; `ffip-diff-mode' inherits from `diff-mode') to the target.
;; file. The target file could be located by searching `recentf-list'.
;; Except this extra feature, `ffip-diff-apply-hunk' is same as `diff-apply-hunk'.
;; So `diff-apply-hunk' can be replaced by `ffip-diff-apply-hunk'.
;; If you use `evil-mode', insert below code into ~/.emacs,
;; (defun ffip-diff-mode-hook-setup ()
;; (evil-local-set-key 'normal "K" 'diff-hunk-prev)
;; (evil-local-set-key 'normal "J" 'diff-hunk-next)
;; (evil-local-set-key 'normal "P" 'diff-file-prev)
;; (evil-local-set-key 'normal "N" 'diff-file-next)
;; (evil-local-set-key 'normal (kbd "RET") 'ffip-diff-find-file)
;; (evil-local-set-key 'normal "o" 'ffip-diff-find-file))
;; (add-hook 'ffip-diff-mode-hook 'ffip-diff-mode-hook-setup)
;; `find-relative-path' find file/directory and copy its relative path
;; into `kill-ring'. You can customize `ffip-find-relative-path-callback'
;; to format the relative path,
;; (setq ffip-find-relative-path-callback 'ffip-copy-reactjs-import)
;; (setq ffip-find-relative-path-callback 'ffip-copy-org-file-link)
;; `ivy-mode' is used for filter/search UI
;; In `ivy-mode', SPACE is translated to regex ".*".
;; For example, the search string "dec fun pro" is transformed into
;; regular expression "\\(dec\\).*\\(fun\\).*\\(pro\\)"
;; `C-h i g (ivy)' for more key-binding tips.
;;
;; `ffip-save-ivy-last' saves the most recent search result.
;; `ffip-ivy-resume' re-use the save result. Both requires `ivy-mode'
;; installed.
;;
;; You can switch to `ido-mode' by `(setq ffip-prefer-ido-mode t)'
;; BSD/GNU Find can be installed through Cygwin or MYSYS2 on Windows.
;; Executable is automatically detected. But you can manually specify
;; the executable location by insert below code into ".emacs",
;;
;; (if (eq system-type 'windows-nt)
;; (setq ffip-find-executable "c:\\\\cygwin64\\\\bin\\\\find"))
;;
;; This program works on Windows/Cygwin/Linux/macOS
;;
;; See https://github.com/technomancy/find-file-in-project for advanced tips.
