Package builder for Iron Realms Nexus

This project is a package builder inspired by and similar in function to muddler for Mudlet. It takes a package definition file that's better suited for humans than the original format and files that can be edited separately as input and creates a package file for the Nexus MUD client of Iron Realms.

Usage

Installation

npm install @keneanung/nexus-package-builder

Running the tool

npx nexus-package-builder [-v <version>] <package-definition.yaml> <output-dir>

Examples:

npx nexus-package-builder input.yaml ./output

npx nexus-package-builder -v 1.2.0 input.yaml ./output

This command will convert the yaml file input.yaml to the package file ./output/input.nxs.

To ease the editing of yaml files, this package also includes a yaml schema file. Some editors can include it with the following comment at the top of the file:

# yaml-language-server: $schema=.node_modules/@keneanung/nexus-package-builder/resources/nexus-schema.json

The only mandatory values for each item are type for reflexes and action for actions as those distinguish which fields are allowed. Default values will be used for missing fields.

NOTE You should not use most actions as they are part of the simplified scripting. If you are already writing code complex enough to warrant the use of external code files, stick to the actions script and possibly function.
