How can I change the face of scalar variables in emacs cperl-mode?

Question

In cperl-mode I am able to change the array and hash faces with Mx customize-group RET cperl-faces RET , and change Cperl Hash Face and Cperl Hash Face . But I can not see any option for changing the scalar variables color.

I have tried to change font-lock-variable-name-face both inside the code or from Cperl Ps Print Face Properties (where I really want to change the color is in the print) but It does not work. I have tried several cperl-modes from 4.32 to the rockway-perl6-branch .

Also I would like not to have the $ colored in the variables, therefore the sigil would stand out better in the printouts (this was asked already here but not resolved).

could someone provide me any hints?

Answer 1

Well, first you'd have to modify cperl-mode to fontify scalar variables. It only highlights arrays and hashes. It doesn't apply any face to scalars, except in certain constructs like my .

Answer 2

我知道这个问题已经过时了，但是当我搜索这个问题时，我想发布我的解决方案：运行Mx customoize-group并将cperl-highlight-variables-indiscriminately设置为t或只是手动编辑你的.emacs 。
