Part 2: Thymeleaf template Engines for B4J

Themeleaf documents: https://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html

-AdditionalJar:

Code: Copy

#AdditionalJar: thymeleaf-3.1.1.RELEASE.jar
#AdditionalJar: ognl-3.3.4.jar
#AdditionalJar: javassist-3.29.0-GA
#AdditionalJar: attoparser-2.0.6.RELEASE
#AdditionalJar: unbescape-1.1.6.RELEASE
#AdditionalJar: sqlite-jdbc-3.42.0.0

- Step 1: Create a Thymeleaf template:

Code: Copy

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<meta http-equiv='Content-Type' content='text/html; charset=UTF-8' />
<head>
<title th:text="${pagetitle}"></title>
<meta name="description" th:content="${des}"/>
<meta property="og:description" th:content="${vietnamese}" />
<link rel="canonical" th:href="${canonical}"/>
</head>
    <body>
    <h1 th:text="${h1}"></h1>
        
    <div th:if="${is_caculator == true}">
     <p><span>X1 + X2 = </span><span th:text="${x1 + x2}"></span></p>
    </div>
    
    <h2>LOOOOOOOP</h2>
    <ul th:each="myarr: ${myarrs}">
        <li  th:text="${myarr}"></li>
    </ul>
    
</div> 
</body>
</html>

- Step 3: Rending

B4X: Copy

Dim Thymeleaf As ThymeleafSupport
    Dim ThymeleafTemplate As String = File.Combine(File.DirApp & "/www/templates","template1.htm")
    Dim variable As Map
    variable.Initialize
    variable.Put("date", DateTime.Date(DateTime.Now))
    variable.Put("uri", "https://tummosoft.com")
    variable.Put("user", myUser.User)
    variable.Put("roles", myUser.Roles)
    variable.Put("logout", "/logout.do")
    
    Thymeleaf.Initialize
    Thymeleaf.Encoding = "UTF-8"
    Thymeleaf.Cacheable = True
    '1200000L // TTL=20m
    Thymeleaf.CacheTTLMs = 1200000
    Thymeleaf.Variables = variable
    
    Thymeleaf.setVariable("pagetitle","Hello world")
    Thymeleaf.setVariable("des","单词意思是灵活的意思")
    Thymeleaf.setVariable("canonical","http://127.0.0.1/home")    
    Thymeleaf.setVariable("vietnamese","Xin chào các bạn!!!")
    
    Dim map2 As Map
    map2.Initialize
    
    Dim x1 As Int = 3
    Dim x2 As Int = 4
    
    map2.Put("h1", "This is h1 tag")
    map2.Put("is_caculator", True)
    map2.Put("x1", x1)
    map2.Put("x2", x2)
    
    Thymeleaf.Variables = map2
    
    Dim arr() As String = Array As String ("Monday","Tuesday", "Wednesday", "Thursday", "Friday")
    Thymeleaf.setVariable("myarrs", arr)
    
    Dim info As infoData
    info.Initialize
    info.Name = "DAVID"
    info.Age = "25"
    Thymeleaf.setVariable("authors", info)
    
    Dim html As String = Thymeleaf.toHTML(ThymeleafTemplate)
        
    'Log(html)
    resp.CharacterEncoding = "UTF-8"
    resp.Write(html)

[Updated] ThymeleafSupport 1.2
- Change "JSPSupport" class name to "ThymeleafSupport"
- Add Charsert mothod

tummosoft · Jul 27, 2023

[Updated] ThymeleafSupport 1.22
------------------------------------
[1] Read .properties files from template:
- Set your Thymeleaf template and .properties files, there are two files with the same name in the same folder.
----------- [template1.properties files]

Code: Copy

home.welcome=I am working with .properties file
logo=Good Thymes Virtual Grocery logo
date.format=MMMM dd'','' yyyy
home.custom=This is first tag, {0}, this this end tag

---------- [template1.html]

B4X: Copy

    <h1 th:utext="#{home.welcome}"></h1>

[2] Define a Thymeleaf fragment

Code: Copy

<!DOCTYPE html>

<html xmlns:th="http://www.thymeleaf.org">

  <body>
 
    <div th:fragment="copy">
      &copy; 2011 The Good Thymes Virtual Grocery
    </div>
 
  </body>
 
</html>

B4X: Copy

<div th:insert="~{\footer::copy}"></div>

[3] New methods: Thymeleaf.Prefix, Thymeleaf.Suffix;

- The method Prefix will help define abosute path of templates file.

B4X: Copy

Dim Thymeleaf As ThymeleafSupport
    Dim ThymeleafTemplate As String = File.Combine(File.DirApp & "/www/templates","")
   
    Thymeleaf.Initialize

    Thymeleaf.Prefix = ThymeleafTemplate
    Thymeleaf.Suffix = ".html"
' --------------------
Dim html As String = Thymeleaf.toHTML("/template1.html")

The examples was attached to 1st post!

Part 3: jFileSupport library

The jFileSupport library has been modified by me from the B4J library, primarily to provide Unicode support and incorporate a few other necessary functions for the purpose of designing applications that operate as web servers.

Code: Copy

#AdditionalJar: commons-codec-1.16.0.jar

- Reading and writing config file (map) with Unicode

Code: Copy

Dim jFile As jFileSupport
    
    Dim unicodeMap As Map = jFile.ReadMapUnicode(File.DirApp & "/MapUnicode", "tiếng-việt.txt")
        
    For i=0 To unicodeMap.Size - 1
        Log(unicodeMap.GetValueAt(i))
    Next
    
    jFile.WriteMap(File.DirApp & "/MapUnicode", "writeUTF-8.txt", unicodeMap)

- Read file meta data

Code: Copy

Dim jFile As jFileSupport
    Dim path As String = File.Combine("C:\Users\Admin\Documents", "cmnd1.jpg")
    Dim m1 As String = jFile.FileMetadataToJson(path)

- Read checksum

B4X: Copy

Dim checksum As String = jFile.getFileChecksum("C:\Users\Admin\Documents", "cmnd1.jpg")
    Log(checksum)

- Rename File

Code: Copy

jFile.RennameFile(source, target)

- Set Permissions (only Linux)

Code: Copy

jFile.setFilePermissions(target, "rwxr-x---")
    jFile.setDirectoryPermissions(target, "rw-------")

[updated] jFileSupport - v 1.41
* Add function: recognizedSignatures
When your website allow user upload document, the server will face various events: ativrius,harm files... Therefore, recognizedSignatures will help you check the sign of document when user upload and it can make decision: keep files or delete them.

You can find the sign of any files on there: https://en.wikipedia.org/wiki/List_of_file_signatures, and put them it on to array: Array As String("89504E","504B03","000001")

Code: Copy

Dim jFile As jFileSupport
    Dim path As String = File.Combine("C:\Users\Admin\Downloads", "laco.png")
    jFile.recognizedSignatures = Array As String("89504E","504B03","000001") 
    Dim rs As Int = jFile.CheckFileSignatures(path)
    Log(rs)

result = 0; -> File type is recognized
result = 1; -> File type is not recognized
result = 2; -> File is too short to determine the signature.

* Other function:
- jFile.ReadAllFolderToJson
- jFile.ReadAllInFolderToXML

[Part 4] jSQLSupport
jSQLSupport is a library was modify by me from Erel's lib (jSQL).
I added some functional accessory:
- Integrated HikariCP, H2 Database Server, H2 Database
* If you want to use the Hikaricp pool, please set h2database.HikariEnable(True)
Extends Java libs:

Code: Copy

Dim h2server As jH2Server
Dim hpathdata As String = File.Combine(File.DirApp,"")
    h2server.InitializeServer("3005", "sa", hpathdata)
    Log(h2server.URL)
    url = h2server.URL

B4X: Copy

Dim h2database As jSQLSupport
    h2database.ExecNonQuery("CREATE TABLE table1 (col1 TEXT , col2 INTEGER, col3 INTEGER)")
    For i=0 To 10
        h2database.ExecNonQuery2("INSERT INTO table1 VALUES(?,?,?)", Array As Object(i, i*2, i*3))
    Next

* Note: If you will use H2 Database like as TCP Server. First, you must create a database on your hard disk. After, using this database for TCP Server.

B4X: Copy

Dim jdbc As String = "jdbc:h2:file:"
h2database.InitializeH2("org.h2.Driver", jdbc, "tummosoft", "sa", "sa", 8192)

B4X: Copy

Dim hpathdata As String = File.Combine(File.DirApp,"")
    hpathdata = hpathdata.Replace("\", "/")
    Dim jdbc As String = "jdbc:h2:" & url & "/" & hpathdata
    
    h2database.InitializeH2("org.h2.Driver", jdbc, "tummosoft", "sa", "sa", 8192)
    h2database.HikariEnable(True)
