;;; Commentary:
;; Help keeping ~/.emacs.d clean.
;; The default paths used to store configuration files and persistent
;; data are not consistent across Emacs packages. This isn't just a
;; problem with third-party packages but even with built-in packages.
;; Some packages put these files directly in `user-emacs-directory'
;; or $HOME or in a subdirectory of either of the two or elsewhere.
;; Furthermore sometimes file names are used that don't provide any
;; insight into what package might have created them.
;; This package sets out to fix this by changing the values of path
;; variables to put configuration files in `no-littering-etc-directory'
;; (defaulting to "etc/" under `user-emacs-directory', thus usually
;; "~/.emacs.d/etc/") and persistent data files in
;; `no-littering-var-directory' (defaulting to "var/" under
;; `user-emacs-directory', thus usually "~/.emacs.d/var/"), and
;; by using descriptive file names and subdirectories when appropriate.
;; This is similar to a color-theme; a "path-theme" if you will.
;; We still have a long way to go until most built-in and many third-
;; party path variables are properly "themed". Like a color-theme,
;; this package depends on user contributions to accomplish decent
;; coverage. Pull requests are highly welcome (but please follow the
;; conventions described below and in the pull request template).
;; `no-littering' cannot help with moving existing files to the new
;; location. You will have to move the files manually. See issue
;; #79 for more information.
;; Usage:
;; Load the feature `no-littering' as early as possible in your init
;; file. Make sure you load it at least before you change any path
;; variables using some other method.
;;
;; (require 'no-littering)
;; If you would like to use base directories different from what
;; `no-littering' uses by default, then you have to set the respective
;; variables before loading the feature.
;;
;; (setq no-littering-etc-directory
;; (expand-file-name "config/" user-emacs-directory))
;; (setq no-littering-var-directory
;; (expand-file-name "data/" user-emacs-directory))
;; (require 'no-littering)
;; Conventions:
;; * A) File names
;;
;; 1. File names are based on the name of the respective Emacs Lisp
;; variables and the name of the respective Emacs package.
;;
;; 2. The name of the respective Emacs package should serve as the
;; prefix of the file name, unless the file is in a subdirectory in
;; which case the name of the subdirectory serves as the prefix.
;;
;; 3. If the name of the package and the prefix of the variable do not
;; match, then we prefer the name of the package.
;;
;; 4. If the name of a path variable ends with `-file`, `-default-file`,
;; `-directory`, `-default-directory`, or something similar, then that
;; suffix is usually dropped from the file name.
;;
;; 5. If applicable, the appropriate extension is added to the file name
;; so that files are visited using the appropriate major-modes and
;; also to provide a hint about the kind of data stored in the file.
;; E.g. if a file contains an S-expression, then the suffix should be
;; `*.el`.
;; * B) File location and subdirectories
;;
;; 1. If a package has only one data file, then that is usually placed in
;; `no-littering-var-directory` itself. Likewise if a package has
;; only one config file, then that is placed in
;; `no-littering-etc-directory` itself.
;;
;; 2. If a package has multiple data (or config files), then those files
;; are placed in a subdirectory of `no-littering-var-directory` (or
;; `no-littering-etc-directory`).
;;
;; 3. If a subdirectory is used for a package's data (or config) file
;; variables, then the name of the directory should match the name of
;; the package in most cases. The subdirectory name may serve as the
;; package prefix of the file name.
;;
;; 4. If a package provides a "framework" for other packages to use,
;; then we may reuse its directories for other packages that make use
;; of that framework or otherwise "extend" the "main package".
;; E.g. we place all `helm` related files in `helm/`.
;;
;; 5. If a package only defines a single variable that specifies a data
;; (or config) directory, then the directory name should
;; nevertheless be just the package name. E.g. the path used for
;; `sx-cache-directory` from the `sx` package is `sx/cache/`, not
;; `sx-cache/`.
;;
;; 6. However if the name of the directory variable implies that the
;; package won't ever define any data (or config) files that won't be
;; placed in that directory, then we use a top-level directory. E.g.
;; when the name of the variable is `<package>-directory`, in which
;; case we would use just `<package>/` as the path.
;; * C) Ordering and alignment
;;
;; 1. The code that sets the values of themed variables is split into two
;; groups. The first group sets the value of variables that belong to
;; packages that are part of Emacs, and the second group is used for
;; variables that are defined by packages that are not part of Emacs.
;;
;; 2. Each of these lists is sorted alphabetically (usually by variable
;; name). Please keep it that way.
;;
;; 3. We attempt to align the value forms inside different `setq` forms.
;; If the symbol part for a particular variable is too long to allow
;; doing so, then don't worry about it and just break the alignment.
;; If it turns out that this happens very often, then we will adjust
;; the alignment eventually.
;; * D) Commit messages
;;
;; 1. Please theme each package using a separate commit and use commit
;; messages of the form "<package>: theme <variable".
;;
;; 2. If a package has several path variables, then you should theme them
;; all in one commit.
;;
;; 3. If the variable names do not fit nicely on the summary line, then
;; use a message such as:
;;
;; foo: theme variables
;;
;; Theme `foo-config-file', `foo-cache-directory',
;; and `foo-persistent-file'.
;; 4. When appropriate add statements like the following to the commit
;; message:
;;
;; - This file is used to store an s-expression.
;; - This file is used to store raw text.
;; - This is the only configuration/data file of the package.
;; - This package does/doesn't take care of creating the containing
;; directory if necessary. (If the package does not do it, then you
;; should also fix that and submit an upstream pull request.)
;;
;; 5. If you are uncertain, then be explicit about it by adding a comment
;; to the pull-request.
