Comment puis-je dire à emacs comment les arguments de ma fonction elisp devraient être indentés?

Question

J'ai écrit la fonction (en fait une macro, mais peu importe) qui fonctionne de manière similaire à progn. Comment puis-je dire à emacs que cette fonction devrait être indentée de la même manière que progn?

Answer 1

Cela devrait le faire

(put 'myfunc 'lisp-indent-function 0) 

Documentation pour lisp-indent-function (trouvé par Ch f Lisp fonction tiret RET):

lisp-indent-function is a compiled Lisp function in `lisp-mode.el'. 

(lisp-indent-function indent-point state) 

This function is the normal value of the variable 
`lisp-indent-function`. It is used when indenting a line within 
a function call, to see if the called function says anything 
special about how to indent the line. 

indent-point is the position where the user typed TAB, or 
equivalent. Point is located at the point to indent under 
(for default indentation); state is the `parse-partial-sexp` 
state for that position. 

If the current line is in a call to a Lisp function which has 
a non-nil property `lisp-indent-function`, that specifies how 
to do the indentation. The property value can be: 

* `defun`, meaning indent `defun`-style; 

* an integer N, meaning indent the first N arguments specially 
    like ordinary function arguments and then indent any further 
    arguments like a body; 

* a function to call just as this function was called. If that 
    function returns nil, that means it doesn't specify 
    the indentation. 

This function also returns nil meaning don't specify the 
indentation.

Comme il est "en fait une macro":

Chig(elisp) Indenting MacrosRET

Dans ce cas:

(defmacro my-macro (&rest body) 
    "Does things" 
    (declare (indent defun)) 
    `(progn ,@body)) 

(my-macro 
    (message "foo") 
    (message "bar"))
