This is a follow-up question to Emacs Lisp: evaluate variable in alist .. I am trying to set default-frame-alist in my .emacs file. Consider, e.g. (setq default-frame-alist '((auto-lower . nil) (auto-raise . nil) (height . 41) (width . 80) (top . 1) (left . 1))) (I have omitted some values) This works fine.. Suppose now I want set the height according to another variable..Say, I stored the integer value 50 in the variable my-height .. How can I set height to the value of my-height ? I have tried (height . my-height) ``(height . ,my-height)` but neither works.. What am I missing here? You need

Is there a way to force a new instance of python-shell while running Emacs? It would be convenient when working on multiple projects with separate working directories (and different sets of modules). Any attempt to invoke python-shell will only pull up the current instance. You need to rename your original python-shell before opening up a new one. Use M - x rename-buffer . Daimrod Renaming the buffer doesn't work for me, but you can use the third parameter of run-python . M - : (run-python nil nil t) RET Since the binding to switch to the current buffer isn't really helpful you can rebound it

I created a function that returns a function in Elisp: (defun singleton-set (elem) (defun f (n) (= n elem)) f) I try to run this in IELM, and it fails: ELISP> (singleton-set 5) *** Eval error *** Symbol's value as variable is void: f ELISP> ((singleton-set 5) 5) *** Eval error *** Invalid function: (singleton-set 5) Due to What is the difference between Lisp-1 and Lisp-2? i changed the code to (defun singleton-set (elem) (defun f (n) (= n elem)) #'f) And invocation to (funcall (singleton-set 5) 5) , but now the error is *** Eval error *** Symbol's value as variable is void: elem I understand

I want to perform the same action that one does by hitting C-Space + moving the arrow keys, but in elisp. Failing to find the right function (if they just were logically grouped in namespaces or somehow tagged...). Which one is it? You can translate keystrokes to elisp using C-h k key . You'll notice the elisp function for setting the mark set-mark-command , takes one non-optional argument. Emacs uses the special interactive function to allow elisp functions to be written naturally with arguments. This allows them to be generic and easy to reuse in other elisp programs, while still possible to

At the top of my elisp module, I want to do something as simple as: (message (concat "Loading " (expand-file-name (current-elisp-module) "."))) You can use the variable load-file-name , which is set by the function load , documented as follows: Full name of file being loaded by `load'. As elaborated in the manual: When Emacs is in the process of loading a file, this variable’s value is the name of that file, as Emacs found it during the search described earlier in this section. Note: buffer-file-name as a routine does not work as you might expect it to. 来源： https://stackoverflow.com/questions
