Using Other Languages

Follow the instructions below if you're using any of the other Extism supported plug-in languages:

  1. Invoke the xtp plugin init command using the XTP CLI and then select the Host App and Extension Point where you want to install the plug-in.

  2. The CLI will then generate an xtp.toml file that provides all the metadata required to make sure your plug-in gets to the right place as well as a markdown file (XTP-PLUGIN-INIT.md) containing further instructions to prepare your plug-in for installation.

  3. Follow the instructions in XTP-PLUGIN-INIT.md, and make sure you install any programming language compilers/tooling needed. The PDK docs are comprehensive and offer a quickstart to help kick things off.

An example xtp.toml should look like:

xtp.toml
app_id = "app_01htbeeftzfqgbeefmxcn7pzbg"

# This is where 'xtp plugin push' expects to find the wasm file after the build script has run.
bin = "plugin.wasm"
extension_point_ids = ["ext_01beef06nkfbeefw06dycfbeef"]

[scripts]
# xtp plugin build runs this script to generate the wasm file, e.g. 
# build="tinygo build -o plugin.wasm -target wasi main.go"
build = ""
