I have this setup for showing a matching paren offscreen. I would like to customize some of the child frame parameters including background color, font color, etc.
(require 'paren) (show-paren-mode 1) (setq blink-matching-paren 'jump-offscreen) (setq show-paren-context-when-offscreen 'child-frame) EDIT: As the OP points out in his answers, this should be:
(with-eval-after-load "paren" (add-to-list 'show-paren--context-child-frame-parameters '(background-color . "black")) (add-to-list 'show-paren--context-child-frame-parameters '(foreground-color . "red"))) Original answer
Try:
(with-eval-after-load "paren" (add-to-list 'show-paren--context-child-frame-parameters '((background-color . "black") (foreground-color . "red")))) Stick the above in a file foo.el , start with emacs -l foo.el and test. If it works, adjust colors to taste and move the code to your init file.
Completely untested.
@NickD thank you! This works:
(with-eval-after-load "paren" (add-to-list 'show-paren--context-child-frame-parameters '(background-color . "cyan")) (add-to-list 'show-paren--context-child-frame-parameters '(foreground-color . "black"))) Yours had both parameters in a list that was being added to another list.
show-paren--context-child-frame-parameters: that's what's used when making the child frame. Untested - no guarantees.
