filter entries?

[drishal]

is there a way to prevent some entries from being displayed? Like say if the length of the file name (with path) exceeds certain characters or if it starts with some other character (like say /ssh:) it should not display in say, recent files

You can delete entries from the recent files.

I mean I wanted to keep it in recentf but prevent some of those from displaying and breaking the dashboard specially if file names are too long

This is not possible at the moment. 🤔 Feel free to open PR for this.

Hi, if the length of the file is the problem there is dashboard-path-style to truncate the file path, also you can customize dashboard-path-max-length and even dashboard-path-shorten-string.
Does this help, or you think we still need the filter function?

Probably add the filter function just for excluding some directories or ssh paths

Hi @drishal I think there's no need for the filter function, at least not in the dashboard. I was looking to recentf-mode and there is recentf-exclude that is:

List of regexps and predicates for filenames excluded from the recent list.
...
A predicate is a function that is passed a filename to check and that must return non-nil to exclude it.

So, you could define a function to filter those files just for the dashboard:

(defun dashboard-recentf-filter (file)
  "Add to ~recentf-exclude~ to filter recent files in dashboard buffer."
  (when (eq (get-buffer dashboard-buffer-name)
            (current-buffer))
    (string-match "^/ssh:" file)))

Add it to the recentf-exclude list:

(add-to-list 'recentf-exclude 'dashboard-recentf-filter)

Hope this help.
