;;; Commentary:

;; This package provides two minor modes which automatically recompile
;; Emacs Lisp source files.  Together these modes guarantee that Emacs
;; never loads outdated byte code files.

;; `auto-compile-on-save-mode' re-compiles source files when they are
;; being saved and `auto-compile-on-load-mode' does so before they are
;; being loaded (by advising `load' and `require').  Both modes only
;; ever _re-compile_ a source file when the respective byte code file
;; already exists but is outdated.  Otherwise they do _not_ compile
;; the source file.

;; Even when using `auto-compile-on-save-mode' it can happen that some
;; source file is newer than the respective byte code file, which is a
;; problem because by default Emacs loads the byte code file even when
;; the respective source file has been modified more recently.

;; Starting with Emacs version 24.4, setting `load-prefer-newer' to t
;; prevents outdated byte code files from being loaded.  However this
;; does not cause re-compilation of the source file, to actually do
;; that `auto-compile-on-load-mode' is still required.

;; Setup
;; -----

;; To reduce the risk of loading outdated byte code files, you should
;; set `load-prefer-newer' and enable `auto-compile-on-load-mode' as
;; early as possible.  Then also enable `auto-compile-on-save-mode'.
;; You should also consider not byte-compiling your personal init
;; file, or setting `load-prefer-newer' in a system-wide init file.

;; If you use `package.el' then use something like this:
;;
;;     ;;; init.el --- user init file
;;     (setq load-prefer-newer t)
;;     (package-initialize)
;;     (require 'auto-compile)
;;     (auto-compile-on-load-mode)
;;     (auto-compile-on-save-mode)

;; otherwise:
;;
;;     ;;; init.el --- user init file
;;     (setq load-prefer-newer t)
;;     (add-to-list 'load-path "/path/to/dash")
;;     (add-to-list 'load-path "/path/to/packed")
;;     (add-to-list 'load-path "/path/to/auto-compile")
;;     (require 'auto-compile)
;;     (auto-compile-on-load-mode)
;;     (auto-compile-on-save-mode)

;; You might want to set the file-local value of `no-byte-compile' to
;; t, e.g. by adding "-*- no-byte-compile: t -*-" (without the quotes)
;; at the end of the very first line.  That way all user files benefit
;; from the protection offered by `load-prefer-newer' and the modes
;; that are defined here, otherwise `~/.emacs.d/init.el' is the only
;; exception.

;; Usage
;; -----

;; Take note of the compile warnings and fix them.

;; To permanently or temporarily toggle automatic compilation of some
;; source file use the command `toggle-auto-compile'.  Since the modes
;; only ever _update_ byte code files, toggling automatic compilation
;; is done simply by either creating the byte code file or by removing
;; it.  `toggle-auto-compile' can also toggle automatic compilation of
;; multiple files at once; see its doc-string for more information.

;; Customization
;; -------------

;; Constantly having the *Compile-Log* buffer pop up when a file is
;; being saved can quickly become annoying.  Obviously the first thing
;; you should do to about that is to actually fix outstanding issues.

;; Once you have done that you might also want to keep that buffer
;; from being automatically displayed and instead only show the number
;; of compile warnings for the current file in the mode-line.

;;     (setq auto-compile-display-buffer nil)
;;     (setq auto-compile-mode-line-counter t)

;; To display the buffer use `M-x auto-compile-display-log' or click
;; on the counter in the mode-line.

;; Using `auto-compile-inhibit-compile-hook' it is possible to inhibit
;; automatic compilation under certain circumstances; e.g. when HEAD
;; is detached inside a Git repository (useful during rebase sessions).

;;; Toggle and Perform Compilation

;;;###autoload
(defun toggle-auto-compile (file action)
  "Toggle automatic compilation of an Emacs Lisp source file or files.

Read a file or directory name from the minibuffer defaulting to
the visited Emacs Lisp source file or `default-directory' if no
such file is being visited in the current buffer.

If the user selects a file then automatic compilation of only
that file is toggled.  Since both `auto-compile-on-save' and
`auto-compile-on-save' only ever _recompile_ byte code files,
toggling automatic compilation is done simply by creating or
removing the respective byte code file.

If the user selects a directory then automatic compilation for
multiple files is toggled as follows:

* With a positive prefix argument always compile source files;
  with a negative prefix argument always remove byte code files.

* Otherwise the existence or absence of the byte code file of
  the source file that was current when this command was invoked
  determines whether byte code files should be created or removed.

* If no Emacs Lisp source file is being visited in the buffer
  that was current when the command was invoked ask the user what
  to do.

* When _removing_ byte code files then all byte code files are
  removed.  If `auto-compile-deletes-stray-dest' is non-nil this
  even includes byte code files for which no source file exists.

* When _creating_ byte code files only do so for source files
  that are actual libraries.  Source files that provide the
  correct feature are considered to be libraries; see
  `packed-library-p'.

* Note that non-libraries can still be automatically compiled,
  you just cannot _recursively_ turn on automatic compilation
  using this command.

* When `auto-compile-toggle-recompiles' is non-nil recompile all
  affected source files even when the respective source files are
  up-to-date.  Do so even for non-library source files.

* Only enter subdirectories for which `packed-ignore-directory-p'
  returns nil; i.e. don't enter hidden directories or directories
  containing a file named \".nosearch\"."

(autoload 'toggle-auto-compile "auto-compile" "\
Toggle automatic compilation of an Emacs Lisp source file or files.

Read a file or directory name from the minibuffer defaulting to
the visited Emacs Lisp source file or `default-directory' if no
such file is being visited in the current buffer.

If the user selects a file then automatic compilation of only
that file is toggled.  Since both `auto-compile-on-save' and
`auto-compile-on-save' only ever _recompile_ byte code files,
toggling automatic compilation is done simply by creating or
removing the respective byte code file.

If the user selects a directory then automatic compilation for
multiple files is toggled as follows:

* With a positive prefix argument always compile source files;
  with a negative prefix argument always remove byte code files.

* Otherwise the existence or absence of the byte code file of
  the source file that was current when this command was invoked
  determines whether byte code files should be created or removed.

* If no Emacs Lisp source file is being visited in the buffer
  that was current when the command was invoked ask the user what
  to do.

* When _removing_ byte code files then all byte code files are
  removed.  If `auto-compile-deletes-stray-dest' is non-nil this
  even includes byte code files for which no source file exists.

* When _creating_ byte code files only do so for source files
  that are actual libraries.  Source files that provide the
  correct feature are considered to be libraries; see
  `packed-library-p'.

* Note that non-libraries can still be automatically compiled,
  you just cannot _recursively_ turn on automatic compilation
  using this command.

* When `auto-compile-toggle-recompiles' is non-nil recompile all
  affected source files even when the respective source files are
  up-to-date.  Do so even for non-library source files.

* Only enter subdirectories for which `packed-ignore-directory-p'
  returns nil; i.e. don't enter hidden directories or directories
  containing a file named \".nosearch\".
