var objData = (JObject)JsonConvert.DeserializeObject(jsonData);
var stubble = new StubbleBuilder().Build();
string body = stubble.Render(template.TemplateBody, objData);

In our C# code, we have a string-based variable called template.TemplateBody which contains the following Mustache-based Stubble template:

{{#should_render}} If the relevant varvalue objDatain =the (JObject)JsonConvert.DeserializeObject(jsonData);custom_parameters_json
is true then this should be shown! {{/should_render}}
List seems to work varas stubbleexpected ={{#my_list}} newitem: StubbleBuilder(){{.Build();
 }} {{/my_list}}
{{#truthy_value}} Truthy values should also work {{/truthy_value}}
{{#some_string}} String should be rendered if it stringis bodynot =null stubble.Render(template{{.TemplateBody, objData);}}
{{/some_string}}

In our C# code, we have a C# string-based variable called template.TemplateBody which contains the following mustache-based formatted Stubble template:

{{#should_render}} If the relevant value in the custom_parameters_json is true then this should be shown! {{/should_render}}
List seems to work as expected {{#my_list}} item: {{.}} {{/my_list}}
{{#truthy_value}} Truthy values should also work {{/truthy_value}}
{{#some_string}} String should be rendered if it is not null {{.}} {{/some_string}}

Here is a generalized format of the jsonJSON-based input testtest data:

{ "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "should_render": { "type": "boolean" }, "my_list": { "type": "array" }, "truthy_value": { "type": "integer" }, "some_string": { "type": "string" } } }

{
 "$schema": "https://json-schema.org/draft/2020-12/schema",
 "type": "object",
 "properties": {
 "should_render": { "type": "boolean" },
 "my_list": { "type": "array" },
 "truthy_value": { "type": "integer" },
 "some_string": { "type": "string" }
 } 
}

In our C# code, we also have a C# string-based variable called jsonDatajsonData:

"{"should_render":true,"my_list":["a","b","c"],"truthy_value":1,"some_string":"My String"}"

{
 "should_render":true,
 "my_list": ["a","b","c"],
 "truthy_value":1,
 "some_string":"My String"
}

Ultimately, the jsonDatajsonData will be deserialized into a C# object-based, and placedstored in a variable called objDataobjData:

{{ "should_render": true, "my_list": [ "a", "b", "c" ], "truthy_value": 1, "some_string": "My String" }}

{ 
 "should_render": true,
 "my_list": ["a", "b", "c"],
 "truthy_value": 1,
 "some_string": "My String" 
}

After, one applies applying the aforementioned stubbleStubble template to said jsonthe JSON object data, it renders the following output:

\nList seems to work as expected\nitem: a\nitem: b\nitem: c\n\n\n"

\nList seems to work as expected\nitem: a\nitem: b\nitem: c\n\n\n

In the input json-based input testJSON test data, the should_rendershould_render is set to true:

"should_render": true

"should_render": true

Therefore, I am asking:

whyWhy did the Stubble API fail to render thatthe statement "If the relevant value in the custom_parameters_json is true then this should be shown!" when the should_render's valueshould_render was set to true:?

{{#should_render}} If the relevant value in the custom_parameters_json is true then this should be shown! {{/should_render}}

{{#should_render}} If the relevant value in the custom_parameters_json is true then this should be shown! {{/should_render}}

Why did the Stubble API fail to render the statement "Truthy values should also work" when the truthy_value's valuetruthy_value was set to 1?

{{#truthy_value}} Truthy values should also work {{/truthy_value}}

{{#truthy_value}} Truthy values should also work {{/truthy_value}}

Why did the Stubble API fail to render the statement "String should be rendered if it is not null {{.}}" when the some_string's valuesome_string was populated:?

{{#some_string}} String should be rendered if it is not null {{.}} {{/some_string}}

{{#some_string}} String should be rendered if it is not null {{.}} {{/some_string}}

Could someone please tell meexplain what modifications that one might need to make in orderbe needed to get get the following rendered output?

If the relevant value in the custom_parameters_json is true then this should be shown!

C# Stubble API for processing json-based data with a mustache-based logic-less template fails to render output data properly

Here is some information about the technologies used in my application:

Microsoft Visual Studio Enterprise 2022 (64-bit) - Current
Stubble.Core version 1.10.8 ( library used to apply Mustache "logic-less templates" to json input data )
.NET 6.0

Here is the snippet of the C# code that invokes Stubble API:

 var objData = (JObject)JsonConvert.DeserializeObject(jsonData);
 var stubble = new StubbleBuilder().Build();
 string body = stubble.Render(template.TemplateBody, objData);

In our C# code, we have a C# string-based variable called template.TemplateBody which contains the following mustache-based formatted Stubble template:

{{#should_render}} If the relevant value in the custom_parameters_json is true then this should be shown! {{/should_render}}

List seems to work as expected {{#my_list}} item: {{.}} {{/my_list}}

{{#truthy_value}} Truthy values should also work {{/truthy_value}}

{{#some_string}} String should be rendered if it is not null {{.}} {{/some_string}}

Here is a generalized format of the json-based input test data:

{ "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "should_render": { "type": "boolean" }, "my_list": { "type": "array" }, "truthy_value": { "type": "integer" }, "some_string": { "type": "string" } } }

In our C# code, we have a C# string-based variable called jsonData

"{"should_render":true,"my_list":["a","b","c"],"truthy_value":1,"some_string":"My String"}"

Ultimately, the jsonData will be deserialized into C# object-based, and placed in a variable called objData:

{{ "should_render": true, "my_list": [ "a", "b", "c" ], "truthy_value": 1, "some_string": "My String" }}

After, one applies the aforementioned stubble template to said json object data, it renders the following output:

\nList seems to work as expected\nitem: a\nitem: b\nitem: c\n\n\n"

In the input json-based input test data, the should_render is set to true

"should_render": true

Therefore,

why did the Stubble API fail to render that statement "If the relevant value in the custom_parameters_json is true then this should be shown!" when the should_render's value was set to true:

{{#should_render}} If the relevant value in the custom_parameters_json is true then this should be shown! {{/should_render}}

Why did the Stubble API fail to render the statement "Truthy values should also work" when the truthy_value's value was set to 1

{{#truthy_value}} Truthy values should also work {{/truthy_value}}

Why did the Stubble API fail to render the statement "String should be rendered if it is not null {{.}}" when the some_string's value was populated:

{{#some_string}} String should be rendered if it is not null {{.}} {{/some_string}}

Could someone please tell me what modifications that one might need to make in order to get the following rendered output?

If the relevant value in the custom_parameters_json is true then this should be shown!

List seems to work as expected item: a item: b item: c

Truthy values should also work

String should be rendered if it is not null My String
