Gojekyll Plugin Status

Gojekyll doesn't include an extensible plugin system¹.

The functionality of some plugins is built into the core program:

¹ (1) The code and internal APIs are too immature for this; and (2) the natural way of implementing this only works on Linux.

³ “Core” plugins are referenced in the main Jekyll documentation.

The Official Plugins section of the Jekyll documentation, and the #Official tag of Awesome Jekyll Plugins, look dated; I didn't use those.

⁴ These don't seem that useful with source control and CI. (Post dates are included.)
