Mustachio Extism Plugin

This Extism plugin allows you to use Postmark's Mustachio templating engine from anywhere you can run Extism plugins

Usage

The plugin has one action, combine, that accepts the following JSON input:

{
  "template": "Your Mustachio Template",
  "model_json": "A String containing the model data to combine with the Mustachio Template, serialized as JSON"
}

Example payload

{
  "template": "Dear {{name}}, this is definitely a personalized note to you. Very truly yours, {{sender}}",
  "model_json": "{\"name\": \"John\", \"sender\": \"Sally\"}" 
}

Build and run

dotnet build ./MustachioPlugin.csproj

extism call ./bin/Debug/net8.0/wasi-wasm/AppBundle/MustachioPlugin.wasm combine  --input '{"template": "The number is {{ a }}", "model_json": "{\"a\": 20}"}"' --wasi
# => The number is 20

Publish

dotnet publish ./MustachioPlugin.csproj

Now you can find a trimmed MustachioPlugin.wasm file in bin/Release/net8.0/wasi-wasm/AppBundle

If you're using dotenvx to set WASI_SDK_PATH

dotenvx run -- dotnet build
dotenvx run -- dotnet publish
