Configure ignore files, from the prettier config file

[sean-au]

Environments:

• Prettier Version: 2.7.1
• Running Prettier via: node.js
• Runtime:
• Operating System: node.js
• Prettier plugins (if any):

Steps to reproduce:

Expected behavior:

.prettierrc.json

{
"ignoreFiles" : [ "/build/**"}
}

Actual behavior:

Its not possible add an ignore config to prettiers config file (based on the docs).
The only ways seems to be to have to use a .prettierignore file.
While this is easy, its one more config file to deal with. EsLint and Sylelint both allow setting ignores in the config file.

Do you have a use case you would like to write in .prettierrc instead of .prettierignore? At least for me, .prettierignore is enough.

[sean-au]

The main use case for me is when I have stylelint, eslint and markdownlint set upalong with prettier. I can copy and paste out of their json config files (all use a an array to set ignores). Whereas prettier I can't reuse the ignore config, unless I create 4x separate ignore files.

I was also looking for this after discovering ESLint's ignorePatterns in the config file instead of .eslintignore. It could reduce the number of configuration files, and potentially make it easier to reuse ignore patterns between ESLint and Prettier.

I believe this is required to bring prettier's configuration behavior in line with ESLint and StyleLint.

I like this suggestion by @ivodolenc: #12672 (comment) (ignorePatterns in prettier.config.js like in ESLint)

[kevinwolfcr]

This would be super easy for sharing configuration and ignored files. @fisker any plans to implement this? It's not a breaking change and an opt-in feature.

[kachkaev]

@kevinwolfcr there exists a work-in-progress PR that aims to do something similar: #12672. #3460 is the main discussion thread for this feature request. That other issue is named a bit differently, but comments suggest to use the same approach as here (search for ignorePatterns). Let's close this one as duplicate to keep the discussion in one place.
