 Posted: Wed Jan 03, 2024 3:14 pm Post subject: elisp help wanted for dynamic root of file path... [fixed] |
 |
|
Currently within setq() | Code: | auto-save-file-name-transforms `((".*" "~/.emacs.d/backups/" t))
|
works fine.
I'd like to use user-emacs-directory instead as in: | Code: | (list ".*" (concat user-emacs-directory "backups/") t)
|
which returns: | Code: | | (".*" "~/.emacs.d/backups/" t) |
Now only surrounding '() are missing, and I don't know how to achieve it.
Seems like it should be doable using a variable for the relative path, but this is just what I want to avoid.

If I understand you correctly, you are looking for something like
| Code: | | (setq auto-save-file-name-transforms `(( ".*" ,(file-name-concat user-emacs-directory "backups/") t))) |

That works, Nice
I also have similar issue with | Code: | | undo-tree-history-directory-alist '(("." . "~/.emacs.d/undo-tree")) |
May be you also have a clue?

Perhaps i'm misunderstanding what you're after, but doesn't doing the same thing do what you want?
| Code: | | (setq undo-tree-history-directory-alist `(("." . ,(file-name-concat user-emacs-directory "undo-tree/"))) |
or, if you want to be more explicit, rather than using quasiquoting:
| Code: | | (setq undo-tree-history-directory-alist (list (cons "." (file-name-concat user-emacs-directory "undo-tree/")))) |

Both of you have saved my day.
I should explain I made a mistake in the first hardcoded path I provided, as original snippet doesn't require final /.
The second snippet is genuine in this respect.
I copied & pasted the first example, which worked seamlessly.
When I tried to apply my understanding of the 'recipe' to the second case I failed to add the final /.
Thus my second call for help.
As you might have guess, I still very noob when it comes to operation on lists.
Saying here "I understand quickly must must be taught for quite a while" 
Time for lisp homework
