Nameless — less is more
Hide package namespaces in your emacs-lisp code.
Simply put, turn on this minor mode, and the namespace prefix of the
package you’re editing will be hidden by a
:. Here’s a comparison.
The image to the left is what you normally see. The image to
the right has
nameless-mode turned on.
To use this package add the following configuration to your Emacs init file.
(add-hook 'emacs-lisp-mode-hook #'nameless-mode)
You can configure a string to use instead of
: by setting the
nameless-prefix, and the name of the face used is
You can even just hide the prefix completely by setting this variable
to an empty string.
While the mode is active, the
C-c C-- key inserts the
package namespace if appropriate.
Quickly typing the namespace
nameless-mode binds the
C-c C-- key to
nameless-insert-name, which immediately inserts the current name for
you, or even expands aliases to the names they point to.
Let’s say you’re in a file called
C-c C-- → foo-bar- fl C-c C-- → font-lock-
There’s also a command called
You can bind this to the
_ key and make it even faster to
insert the name.
Configuring the namespace name
Nameless guesses the package name with the
function, but sometimes this might not match the name you want to use.
In these situations, simply set
nameless-current-name as file-local variable.
To do that, invoke the following command:
M-x add-file-local-variable RET nameless-current-name RET "package-name"
You can also set the same name for all lisp files in a project by setting dir-local variables with:
M-x add-dir-local-variable RET emacs-lisp-mode RET nameless-current-name RET "package-name"
If you don’t want Nameless to use a namespace name at all (neither
manual nor automatic), you can set
nil. This will disable this functionality, so that Nameless will
only use aliases (see next item).
Requiring other packages as aliases
Nameless can also be used to “import” other packages as aliases. For
instance, in the default behaviour, functions in the
font-lock-add-keywords) will be displayed with the
fl: prefix (e.g.,
You can configure your own aliases globally with
(setq nameless-global-aliases '(("fl" . "font-lock") ("s" . "seq") ("me" . "macroexp") ("c" . "cider") ("q" . "queue")))
You can also configure aliases per-file by setting
as a file-local variable.
;; Local Variables: ;; nameless-aliases: (("c" . "cider")) ;; End:
Note that there’s no
You can also configure it for a whole project, by setting it as a dir-local variable.
Private symbols in elisp are written with an extra dash after the
foobar--indent-impl). With Nameless, these are usually
:-indent-impl, but you can also make them be displayed
::indent-impl by setting
(setq nameless-private-prefix t)
Packages that don’t use
- (hyphen) as a separator
You can set
nameless-separator file-locally to whatever separator
you package uses. Most packages use hyphens, but some use
You can also set it to
nil globally and the separator will never be
hidden, and will not be inserted with `-name-insert-` functions.
Indentation and paragraph filling
Hiding parts of symbols could affect the way Emacs indents your code and fills your paragraphs. Nameless lets you decide whether you want that to happen or not.
The default behavior is that code is indented according to what you
see (i.e., according to short symbols), but text inside strings is
not. So text inside strings will be filled in the same way as if you
nameless-mode. Here’s how a docstring might be filled
If point is immediately after an alias configured in the name you had in `:aliases' or `:global-aliases', replace it with the full name for that alias.
Altough it may look strange that the second line is so short, that’s
the correct way. When viewed in a
*Help* buffer, that docstring will
look like this:
If point is immediately after an alias configured in the name you had in `nameless-aliases' or `nameless-global-aliases', replace it with the full name for that alias.
To change this behavior, configure the variable
