Exclude a folder from files to be checked/watched

[diessica]

hexo server command was taking too much to execute in terminal, then I added the --debug flag and have found out that Hexo is actually looking for changes in some folders unnecessarily. I want to exclude them from the files to be checked when I hexo server - folders just like node_modules:

[...]
03:53:33.612 DEBUG Unchanged: themes/[...]/node_modules/[...]
03:53:33.612 DEBUG Unchanged: themes/[...]/node_modules/file[...]
03:53:33.612 DEBUG Unchanged: themes/[...]/node_modules/file3[...]
03:53:34.097 DEBUG Theme config loaded.
03:53:34.097 DEBUG Processed: _config.yml
[...]

Is there a setting for ignoring folders? I was thinking about skip_render or exclude_generator, but those didn't work. I guess the documentation wasn't that clear about their roles.

Thank you!

TL;DR
Hexo is watching files I don't want it to watch. How can I ignore those folders in my blog folder?

Will this be useful?

Got here from Google considering this is an undocumented feature and non-trivial.

I think this feature was added in #2631 from issue #2632. This adds a global ignore: parameter to exclude folders from watching/processing, but I could only get it to work from the projects config and not the theme config (though you can still ignore theme files).

Adding the following property to your _config.yml will stop it from watching/processing these files during generation or serving (in this example, the themes node_modules folder). It uses minimatch globs.

ignore: ['**/themes/**/node_modules/**', '**/themes/**/node_modules', '**/themes/**/.git', '**/themes/**/.git/**']

The actual implementation site can be found in box.js
