Generic way to author text in AEM dialog

I am trying to author text in dialog, text contains dynamic values like name etc. I tried declaring sightly variable names in AEM dialog to fetch the data dynamically but it didn't work.

 I tried below approaches..

Approach 1:

/*
  * Using String format
  */
  String authoredText= "Hi %s, welcome to %s";
  authoredText = authoredText.format(authoredText,"Kishore","AEM Quickstart");
  log.info("---Using String format----\n"+authoredText);

Approach 2:

/*
  * Using StrSubstitutor - org.apache.commons.lang.text.StrSubstitutor
  */
  Map valuesMap = new HashMap();
  valuesMap.put("name", "Kishore");
  valuesMap.put("blog", "AEM Quickstart");
  String templateString = "Hi ${name}, welcome to ${blog}.";
  StrSubstitutor sub = new StrSubstitutor(valuesMap);
  String resolvedString = sub.replace(templateString);
  log.info("---Using StrSubstitutor----\n"+resolvedString);

Approach 3:

/**
   * Using String replace
   */
  String authoredText= "Hi ${name}, welcome to ${blog}";
  authoredText = authoredText.replace("${name}","Kishore");
  authoredText = authoredText.replace("${blog}","AEM Quickstart");
  log.info("---Using String replace----\n"+authoredText);

From above approaches we can author the text in any of the format and parse it in java and we can get the text in HTL.

AEM Code Snippets

// to get list of selectors in an array

String[] selectors = slingRequest.getRequestPathInfo().getSelectors();

// to get a page from a path

Page page = pageManager.getPage(path);

// to get any containing page for a resource

Page page = pageManager.getContainingPage(resourceResolver.getResource(path));

// to get a session in JSP

final SlingRepository repos = sling.getService(SlingRepository.class);
session = repos.loginAdministrative(null);
// to get query object and run a query

//build query using search in crx explorer or crxdelite

String stmt = "select * from cq:Page where jcr:path like '/content/training/%' and contains(*, '" + slingRequest.getParameter("q") + "') order by jcr:score desc";

HTL (Sightly) Code Snippets

Below are few HTL syntax used frequently in AEM.

1. HTL does not support JSP tag libraries.

2. Including a script: data-sly-include instead of cq:include

<cq:include script="template.html"/> //Including a HTL file in JSP
<sly data-sly-include="template.jsp"/> //Including a JSP file in HTL

The element on which a data-sly-include has been set is ignored and not displayed.

3. Including a Resource: data-sly-resource

Includes the result of rendering the indicated resource through the sling resolution and rendering process. Basic syntax-

<article data-sly-resource="path/to/resource"></article>

Override resourceType of an include-

<article data-sly-resource="${'path/to/resource' @ resourceType='my/resource/type'}"></article>

Change the wcmmode-

<article data-sly-resource="${'path/to/resource' @ wcmmode='disabled'}"></article>
