If you want M-x compile to do the right thing for your project, you can do something like this:
(add-hook scala-project-file-visit-hook (lambda (nil) (set (make-local-variable 'compile-command) (format "cd %s; make -f Makefile.scala" (eproject-root)))))
If you want to examine every file looking for “TODO” comments, a quick invocation of rgrep might work:
(rgrep "TODO" "*" (eproject-root))
If you wanted to be pedantic, you could consult eproject’s list of relevant and irrelevant files and include/exclude them accordingly. You could also open each file, load the syntax table, and only search inside of comments. I would be happy to accept such code into eproject-extras, but I am a little too lazy to write it myself :)
Edit: This is implemented now; just run
I have a somewhat complex window configuration:
The screen is split three times vertically. The first third is usually split once horizontally and has an IRC window and a shell, and the other two thirds show the code for my current project. Sometimes, something (hello, Gnus) messes that up, and it’s a bit of work to restore. With eproject, I can find my most recently used project and find the two most-recently-visited buffers in that project. It’s then a simple matter of programming to setup my window configuration:
(defun first-matching-buffer (predicate) "Return PREDICATE applied to the first buffer where PREDICATE applied to the buffer yields a non-nil value." (loop for buf in (buffer-list) when (with-current-buffer buf (funcall predicate buf)) return (with-current-buffer buf (funcall predicate buf)))) (defun fix-windows () "Setup my window config." (interactive) (let ((current-project (first-matching-buffer (lambda (x) (ignore-errors (eproject-name))))) (current-irc-window (first-matching-buffer (lambda (x) (and (eq major-mode 'rcirc-mode) x)))) (current-shell (or (first-matching-buffer (lambda (x) (and (or (eq major-mode 'eshell-mode) (eq major-mode 'term-mode)) x))) (eshell)))) (delete-other-windows) (split-window-horizontally) (split-window-horizontally) (window-number-select 1) (split-window-vertically) (labels ((show (x) (set-window-buffer nil (or x (get-buffer-create "*scratch*"))))) (window-number-select 1) (show current-irc-window) (window-number-select 2) (show current-shell) (let ((cur)) (loop for i in '(3 4) do (window-number-select i) (show (first-matching-buffer (lambda (x) (and (equal (ignore-errors (eproject-name)) current-project) (not (equal cur (buffer-name x))) x)))) (setf cur (buffer-name (current-buffer)))))) (balance-windows)))
(On github, http://github.com/jrockway/elisp/blob/8de738e7c37c4b57aee0e777883a2aaf58c4035e/_local/windowing-extras.el#L22. Textile sucks!)
Anything.el is an enhanced version of find-file, switch-to-buffer, etc. It gives functionality like, e.g., when you call find-file, it shows your recentf and open buffers and lets you autocomplete on them.
Obviously, we want to integrate this with eproject, so that find-file will search for files in the current eproject.
First we create anything sources, which are objects that anything.el does autocompletion on.
(defvar anything-c-source-eproject-files '((name . "Files in eProject") (init . (lambda () (if (buffer-file-name) (setq anything-eproject-root-dir (eproject-maybe-turn-on)) (setq anything-eproject-root-dir 'nil) ))) (candidates . (lambda () (if anything-eproject-root-dir (eproject-list-project-files anything-eproject-root-dir)))) (type . file)) "Search for files in the current eProject.") (defvar anything-c-source-eproject-buffers '((name . "Buffers in this eProject") (init . (lambda () (if (buffer-file-name) (setq anything-eproject-root-dir (eproject-maybe-turn-on)) (setq anything-eproject-root-dir 'nil)))) (candidates . (lambda () (if anything-eproject-root-dir (mapcar 'buffer-name ( cdr (assoc anything-eproject-root-dir (eproject--project-buffers))))))) (volatile) (type . buffer)) "Search for buffers in this project.")
Then you can add the sources to your anything functions:
(defun anything-for-buffers () "Preconfigured `anything' for opening buffers. Searches for buffers in the current project, then other buffers, also gives option of recentf. Replaces switch-to-buffer." (interactive) (anything '(anything-c-source-eproject-buffers anything-c-source-buffers+ anything-c-source-buffer-not-found anything-c-source-recentf)))
You can do something similar with anything-for-files (see anything-config.el).
