## Introduction
|
|
|
|
The hilbish.module interface provides a function to load
|
|
Hilbish plugins/modules. Hilbish modules are Go-written
|
|
plugins (see https://pkg.go.dev/plugin) that are used to add functionality
|
|
to Hilbish that cannot be written in Lua for any reason.
|
|
|
|
Note that you don't ever need to use the load function that is here as
|
|
modules can be loaded with a `require` call like Lua C modules, and the
|
|
search paths can be changed with the `paths` property here.
|
|
|
|
To make a valid native module, the Go plugin has to export a Loader function
|
|
with a signature like so: `func(*rt.Runtime) rt.Value`.
|
|
|
|
`rt` in this case refers to the Runtime type at
|
|
https://pkg.go.dev/github.com/arnodel/golua@master/runtime#Runtime
|
|
|
|
Hilbish uses this package as its Lua runtime. You will need to read
|
|
it to use it for a native plugin.
|
|
|
|
Here is some code for an example plugin:
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
rt "github.com/arnodel/golua/runtime"
|
|
)
|
|
|
|
func Loader(rtm *rt.Runtime) rt.Value {
|
|
return rt.StringValue("hello world!")
|
|
}
|
|
```
|
|
|
|
This can be compiled with `go build -buildmode=plugin plugin.go`.
|
|
If you attempt to require and print the result (`print(require 'plugin')`), it will show "hello world!"
|
|
|
|
## Interface fields
|
|
- `paths`: A list of paths to search when loading native modules. This is in the style of Lua search paths and will be used when requiring native modules. Example: `?.so;?/?.so`
|
|
|
|
## Functions
|
|
### load(path)
|
|
Loads a module at the designated `path`.
|
|
It will throw if any error occurs.
