Data structures framework for Skyrim


JContainers is a modding framework that extends Papyrus by implemented basic data structures. It features:

- Data structures (arrays, dictionaries)
- Import and export data to and from JSON files (for ex. read config files, backup data and etc)
- Path resolving - simplifies access to nested data structures
- Lua - the main purpose is to minimize the amount of cumbersome Papyrus code needed to handle data by moving it into Lua scripts
- C++ API - interaction with JC via C++ interface. This mean you can invoke C++ analogue of any Papyrus function JC provides. See developer resources archive for usage example.

Versioning note

JContainers uses semantic versioning scheme - API.FEATURE.PATCH. Essence:

- API version increases when API changes in backward-incompatible way. Note that it's possible to run different plugins with different API versions in parallel. E.g. JC 3.x can be installed alongside with 4.x
- FEATURE version increases when functionality added in a backwards-compatible manner. Mod requiring JC 3.1 will perform well with JC 3.2 and above
- PATCH version increases when tiny bug fixes added.

Bundle or not?

Bundling a resource simplifies installation for end users, and it is harmless for resources like 3D resources, ESP files, it may cause issues in case when a complex mod being bundled. It may freeze bugs in time (a mod X bundles an older version of Y causing issues, fixed long ago), may cause downgrade issue (A mod X bundles an older version of Y, overrides newer version of Y. The Y capable to upgrade itself from an older version, but not vice versa). And the more mods dependent on a shared resource the more noticeable issues may become.

Special thanks

- You (as mod author) are free to bundle this plugin. Note that this may lead to downgrade issue, when your mod bundles older version, overrides new version (bundled by another mod or installed manually), which may lead to JC data loss, JC-dependent mods may stop work. I warned you.
- It's up to you to report to a user of incompatibility of installed JC API version and the version mod has been compiled for the best user's experience. Valid condition is `JC.APIVersion == hardcodedAPIVersion && JC.featureVersion >= hardcodedFeatureVersion`.
- The files in this plugin are not to be modified under any circumstance as that could cause problems when a load order includes multiple mods that use the plugin and one or more mods have modified the files in this plugin.
