Less's import-manager.js calls loadFile with a "callback" argument [1] and file-manager.js calls loadFileSync with an "encoding" argument [2], without which operating in synchronous mode (using the syncImport less option) is broken. [1] https://github.com/less/less.js/blob/4a0026ebf6d4c783365d3701ac796c18dcc9d30f/lib/less/import-manager.js#L119 [2] https://github.com/less/less.js/blob/4a0026ebf6d4c783365d3701ac796c18dcc9d30f/lib/less-node/file-manager.js#L32
When running in sync mode (syncImport option), loadFile should call the callback instead of returning a promise. This change implements logic similar to [1]. [1] https://github.com/less/less.js/blob/49cbe520f6b38b4b8797dcba491501c0c461c7f5/lib/less-node/file-manager.js#L31

I am using
less.renderin synchronous mode (using thesyncImportless option) to preprocess css module files using css-modules-require-hook. However, when using this plugin, less synchronous mode stops working -- the callback passed toless.renderis never called.After some digging, I found that this is because less's
import-manager.jscallsloadFilewith acallbackargument (see here) andfile-manager.jscallsloadFileSyncwith anencodingargument (see here). The FileManager implemented in this module does not forward these arguments along, causing the calls to fail.This PR fixes this module when using
less.renderin synchronous mode by adding the missing arguments.
