Config

Linter config

UI5 Linter searches for package.json in your CWD (Current Working Directory) and locates the config there.

Cache
ui5plugin-parser preload the library metadata and stores it in cache. If "libsToLoad" were changed, it is necessary to clear cache. It is possible by adding --rmcache flag to ui5linter:

ui5linter --rmcache

      /*it makes sense to use only componentsToInclude or componentsToExclude, but not both at once.
      "componentsToExclude" comes in handy when you want to exclude e.g. libraries.
      "componentsToInclude" comes handy when you have many different components which project depends
      on, but it is necessary to lint only one*/
      "componentsToExclude": ["com.custom.library"],
      //Handy to add additional workspace paths if e.g. library is outside of CWD
      "additionalWorkspacePaths": [
        "C:\\MyLibrary",
        "../MyLibrary"
      ]
    }

It is possible to override properties in your package.json. See Configuration example

In case of jsLinterExceptions the exceptions which will be found in package.json of CWD will be added to the default exceptions, in the rest of the cases properties will be overwritten

Parser config

It is possible to add config for ui5plugin-parser as well.

Check ui5plugin-parser -> Config default values as a reference for parser properties
See Configuration example
