How to copy paste without source font lock in emacs?

colors, elisp, emacs

Solution

See the doc for user options `yank-excluded-properties` and `yank-handled-properties`. And start with the doc for `yank`: `C-h f yank`. It tells you:

When this command inserts text into the buffer, it honors the
`yank-handled-properties' and `yank-excluded-properties'
variables, and the `yank-handler' text property.  See
`insert-for-yank-1' for details.

IOW, just tell `yank` not to paste properties such as `face` and `font-lock-face`.

See also the Elisp manual, node `Yanking`.

Problem

When you copy text from one buffer to another (M-w and C-y) it copy text with font-lock and when you paste it it display with colors from the buffer I copied the text. Is it possible to change that to make it display with font from new buffer?
