Profiles manages user-defined sets of generic properties such as user name or mailing address across various buffers. Profiles are aimed towards developers that work on different projects, sometimes under different names, different mailing address, and that wish to apply similar settings across different files.
Profiles provides a higher level functionality that dirvars.el, albeit less invasive. Where dirvars.el requires you to create a file in each of your project files, profiles try to take adventage of the fact that each particular project’s setting are probably similar in some way or require more than just setting user variables. In any case, profiles can be used together with dirvars.el.
For exemple, user Joe is working on project ProjA and ProjB. Both projects imposes that coding style follows “gnu” standards, but Joe generally prefer to work with “elemtel” and this is what he is using for all his other projects. He is also using a different mailing address for both projects, and wants it to be set automatically for his ChangeLog. Fortunatly, Joe uses profiles and he has configured his “~/.emacs” in this way:
(require 'profiles) (profile-define "usual" "Joe" "email@example.com" 'coding-style "elemtel" ; any property value can be attached! 'prefered-license "GPLv2") (profile-define "proj-a-and-b" "Joe" "firstname.lastname@example.org" 'coding-style "gnu" 'prefered-license nil) (setq profile-path-alist '(("/path/to/proj/a" . "proj-a-and-b") ("/path/to/proj/b" . "proj-a-and-b"))) (profile-set-default "usual")
; ...and later in his config file... (add-hook 'c-mode-common-hook '(lambda () (c-set-style (profile-current-get 'coding-style))))
; ...and a little later too... (add-hook 'change-log-mode-hook '(lambda () (setq add-log-full-name (profile-current-name)) (setq add-log-mailing-address (profile-current-mailing-address))))
And voila! his name, mailing address and coding style are now automatically set for ProjA and ProjB to the desired values. This did not require Joe to make any amendement to the project themselves. Adding new profiles will be easy too.
Saving the profile path in your “~/.emacs” is not such a good idea however. Instead you can use the interactive function
`profile-add-regexp-and-save' that will populate
`profile-path-alist' with a new entry. This setting will be saved in the file
You can automatically load the settings of this file by adding:
…in your “~/.emacs”. This file is printed in human readable lisp and can be edited manually, as necessary.
