Find file/directory and review Diff/Patch/Commit quickly everywhere.
User Case One: Find file/directory quickly in current project. The project root is detected automatically if Git/Subversion/Mercurial is used.
User Case Two:
Diff/patch files. Target files could be under any Version Control Software (VCS) or no VCS at all. Please check ffip-diff-* commands.
Features:
- Works on Windows64/Linux/macOS with minimum setup. Only dependency is
BSD/GNU Find - Fast. Tested with 50,000+ files
- Works flawlessly with Tramp Mode
- Uses native API
completing-readand supports ido/helm/ivy/consult/selectrum out of box
Screenshot:
Run make runemacs in this project’s root directory. The demo works out of box.
Place find-file-in-project.el under Load Path. Then add (require 'find-file-in-project) to your configuration.
It is also possible to use melpa; however be aware that as of the time of this writing installation using package.el is not recommended due to flaws in Emacs’s TLS implementation.
Since v3.7, Emacs 24.3 is required.
Since v5.7.5, Emacs 24.4 is required.
Since v6, Emacs 25.1 is required.
Users of Debian ≥10 and derivatives can install this program with the following command:
sudo apt install elpa-find-file-in-project
Since v6, ffip gives you freedom to choose your favorite completion framework.
It only uses builtin api completing-read.
Ido setup,
(setq ffip-prefer-ido-mode t)Helm setup,
(helm-mode 1)Ivy setup,
(ivy-mode 1)Windows setup is as easy as installing Cygwin or MYSYS2 at default directory of any driver. GNU Find executable is detected automatically.
You can also manually specify the executable path,
(when (eq system-type 'windows-nt) (setq ffip-find-executable "c:\\\\cygwin64\\\\bin\\\\find"))NO setup needed.
Project root is automatically detected if Git/Mercurial/Subversion is used.
You can override the default root directory by setting ffip-project-root,
(setq ffip-project-root "~/projs/PROJECT_DIR")Per-project and per-directory setup is easy. Check “Tips” section for details.
Guess the file path at point and try to find file. The path could contain environment variables.
Use the selected region as keyword to search file. If no region is active, you could provide the keyword which could contain wildcard.
If keyword contains line number like “hello.txt:32” or “hello.txt:32:”, we will move to that line in opened file.
If parameter is passed , file will be opened in new window.
If (setq ffip-match-path-instead-of-filename t) is placed before M-x find-file-in-project-by-selected, we try to match selected text with any part of full path before displaying candidates.
It could replace old command find-file-in-project (or ffip) because it’s faster. It was tested searching in 50K+ files without any performance issue.
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.
Use the selected region as keyword to find directory. If no region is active, you could provide the keyword. Keyword could contain wildcard character which passed to Find as value of -iwholename option
If parameter is passed , directory will be opened in new window.
It replaces file path at point with correct relative/absolute path. File path could contain environment variables.
Starts search immediately. This command is slow if there 10K+ files because it use ONLY Emacs Lisp to filter candidates. You should always use find-file-in-project-by-selected in big project..
File/directory searching actions are automatically stored into ffip-find-files-history.
Use ffip-find-files-resume to replay any previous action.
The maximum number of items of the history is set in ffip-find-files-history-max-items.
By default it finds file in project. f its parameter is not nil, it find directory instead.
It’s written in pure Lisp and does not use any third party command line program. So it works in all environments.
Create .dir-locals.el which ”defines the same set of local variables to all the files in a certain directory and its subdirectory”.
You can setup variables like ffip-project-root in this file.
The original setup in .dir-locals.el is respected. This command will merge new setup with old content.
See Emacs manual for technical details.
Like find-file-in-project but find file in current directory.
Like find-file-in-project-by-selected but find file in current directory.
Execute backend from ffip-diff-backends.
The output of backend execution is in Unified Diff Format and is inserted into *ffip-diff* buffer where you can press o, C-c C-c, ENTER , M-x ffip-diff-find-file to open the corresponding file.
ffip-diff-find-file-before-hook is called in ffip-diff-find-file. Two file names are passed to it as parameters. One name is returned by the hook as the file searching keyword.
For example, you can M-x ffip-show-diff to view the git commit and open file inside patch.
, M-x 5 ffip-show-diff executes 5th backend from ffip-diff-backends.
Please press C-h v ffip-diff-backends to view available back-ends.
Other key bindings defined in *ffip-diff* buffer,
| key binding | command |
|---|---|
| p | diff-hunk-prev |
| n | diff-hunk-next |
| P | diff-file-prev |
| N | diff-file-next |
Insert below code into .emacs if you use evil-mode,
(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)You can customize the ffip-diff-backends,
(setq ffip-diff-backends
'(ffip-diff-backend-git-show-commit
"cd $(git rev-parse --show-toplevel) && git diff"
"cd $(git rev-parse --show-toplevel) && git diff --cached"
ffip-diff-backend-hg-show-commit
("Diff from `kill-ring'" . (car kill-ring))
"cd $(hg root) && hg diff"
"svn diff"))Please note some backends assume that the git cli program is added into environment variable PATH.
Find file/directory and copy its relative path into `kill-ring’.
File’s path is copied by default. C-u M-x find-relative-path copy directory’s path.
You can set ffip-find-relative-path-callback to format the string before copying.
;; (setq ffip-find-relative-path-callback 'ffip-copy-reactjs-import)
(setq ffip-find-relative-path-callback 'ffip-copy-org-file-link)Similar to diff-apply-hunk, it applies current hunk on the target file (please note ffip-diff-mode inherits from diff-mode).
The target file could be found by searching (ffip-project-root). You can also apply extra operation on the file in ffip-diff-apply-hunk-hook before hunk applying happens.
For example, for files under Perforce control,
(defun p4-edit-file-and-make-buffer-writable(file)
"p4 edit FILE and make corresponding buffer writable."
(shell-command (format "p4 edit %s" file))
;; make sure the buffer is readable
(let* ((buf (get-file-buffer file)))
(if buf
(with-current-buffer buf
;; turn off read-only since we've already `p4 edit'
(read-only-mode -1)))))
(defun ffip-diff-apply-hunk-hook-setup (file)
(unless (featurep 'init-perforce) (require 'init-perforce))
(if (string-match-p "/myproject/" file)
(p4-edit-file-and-make-buffer-writable file)))
(add-hook 'ffip-diff-apply-hunk-hook 'ffip-diff-apply-hunk-hook-setup)It can filter hunks by their file names.
For example, user input pattern “regex !exclude1 exclude1” means the hunk’s file name does match “regex”, but does not match “exclude1” or “exclude2”.
Please note in “regex”, space represents any string.
Insert file content into current buffer.
All tips are OPTIONAL. find-file-in-project works out of box in 99% cases.
Please insert (setq ffip-use-rust-fd t) into .emacs to use fd (alternative to GNU Find).
ffip-get-project-root-directoryreturn the full path of current project
Here is complete setup you could insert into .emacs=,
;; if the full path of current file is under SUBPROJECT1 or SUBPROJECT2
;; OR if I'm reading my personal issue track document,
(defun my-setup-develop-environment ()
(interactive)
(when (ffip-current-full-filename-match-pattern-p "\\(PROJECT_DIR\\|issue-track.org\\)")
;; Though PROJECT_DIR is team's project, I care only its sub-directory "subproj1""
(setq-local ffip-project-root "~/projs/PROJECT_DIR/subproj1")
;; well, I'm not interested in concatenated BIG js file or file in dist/
(setq-local ffip-find-options "-not -size +64k -not -iwholename '*/dist/*'")
;; for this project, I'm only interested certain types of files
(setq-local ffip-patterns '("*.html" "*.js" "*.css" "*.java" "*.xml" "*.js"))
;; ignore files whose name match certain glob pattern
(setq-local ffip-ignore-filenames '("*.bmp" "*.jpg"))
;; exclude `dist/' directory
(push "*/dist" ffip-prune-patterns))
;; insert more WHEN statements below this line for other projects
)
;; most major modes inherit from prog-mode, so below line is enough
(add-hook 'prog-mode-hook 'my-setup-develop-environment)All variables may be overridden on a per-directory basis in your .dir-locals.el. See (info “(Emacs) Directory Variables”) for details.
You can place .dir-locals.el into your project root directory.
A 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))
;; Do NOT ignore directory "bin/" when searching
(setq ffip-prune-patterns `(delete "*/bin" ,@ffip-prune-patterns))))
)))As mentioned, ffip-create-project-file could create a minimum .dir-locals.el.
BTW, please use either per-directory setup or per-project setup, NOT both.
