Create a prompt template

You can create prompts using the PromptTemplate class. Prompt templates can take any number of input variables, and can be formatted with input values to generate a prompt.

An example prompt with no input variables

var noInputPrompt = new PromptTemplate("Tell me a joke.");
Console.WriteLine(noInputPrompt.Format(new Dictionary<string, string>()));

> Tell me a joke.

An example prompt with one input variable

var oneInputPrompt =
    new PromptTemplate(template: "Tell me a {adjective} joke.", inputVariables: new[] { "adjective" });

var valuesOneInput = new Dictionary<string, string>
{
    { "adjective", "funny" }
};
Console.WriteLine(oneInputPrompt.Format(valuesOneInput));

> Tell me a funny joke.

An example prompt with multiple input variables

var multipleInputPrompt = new PromptTemplate("Tell me a {adjective} joke about {content}.",
    new[] { "adjective", "content" });

var valuesMultipleInput = new Dictionary<string, string>
{
    { "adjective", "funny" },
    { "content", "chickens" }
};
Console.WriteLine(multipleInputPrompt.Format(valuesMultipleInput));

> Tell me a funny joke about chickens.

You could pass input variables into PromptTempalte constructor as a List<string> but also you could omit it, then it would be built automatically.

var oneInputPrompt = new PromptTemplate(template: "Tell me a {adjective} joke.");

If you want to pass symbols '{' or '}' as a part of a prompt you should escape them like this

 new PromptTemplate(template: "{{ \"code\": \"{value}\" }}");

which will produce final string after formatting and set up value

{ "code": "input value" }

When you want to fill template with values you need to use Dictionary<string, string> where keys should be the same as your input variables and values could be any valid string that need to be fill in template.
