Customisable Keywords

You can also define your own custom keywords in a config file.

If you aren't content with the predefined keywords included, you can now add your own to a .pseudoconfig file located in your user's home directory (~/.pseudoconfig or C:\Users\{username}\.pseudoconfig).

To use this feature you must make sure editor.semanticHighlighting.enabled is set to true in VSCode.

The config file should contain a JSON object, with a single key "custom" containing an object with a single key "keyword" (the only scope currently supported for custom highlighting) which has a value of an array of strings, which holds your custom keywords.

Example:

{
    "custom": {
        "keyword": [
            "customKeyword",
            "exampleWord"
        ]
    }
}

In the above example, both customKeyword and exampleWord will be highlighted as keywords.

NOTE: You must reload the extension after editing the config file.

NOTE: Local config files in the active directory are not currently supported. You can currently only use a global config file which is placed in the home directory.
