This syntax file adds syntax/highlighting groups for PHP 8 attributes. I wrote this as an addition to the official Vim php syntax which lacks attributes.
Either copy the file keeping the directory structure to your .vim home directory or use a plugin
manager.
Plug:
Plug 'dr0bz/php-attributes-syntax'
This syntax will introduce few new groups and link them to standard vim sytnax groups:
| New Group | Linked To |
|---|---|
| phpAttributeKeyword | Keyword |
| phpAttributeClassKeyword | Keyword |
| phpAttributeBoolean | Boolean |
| phpAttributeNumber | Number |
| phpAttributeConstant | Constan |
| phpAttributeString | String |
| phpAttributeNamedArgument | Normal |
| phpAttributeFQDN | Normal |
| phpAttributeInitClassName | Normal |
| phpAttributeClassName | Normal |
| phpAttributeBlock | Comment |
You probably want colors that are less intrusive. Since attributes a written in the comment place.
You can just take your regular colors and make them darker. For ex. here is my color of Keyword:
#cc7833
Find your's:
hi Keyword
Then use your color picker to make it a bit darker:
#995924
hi phpAttributeKeyword guifg=#995924
Do this to all attribute groups mentioned above.
Good luck and happy coding in vim:)
