These built-ins you can only use with the loop variable of the list and items directives and of the deprecated foreach directive.
Some explanation of that follows loopVar? When the list directive doesn't specify the loop variable, these built-ins are used with the loop variable of the items directive:.
Loop variable built-ins only use the name of loop variable, so that they can identify the related ongoing iteration. They don't read the value of the loop variable. Hence, this is a parsing error:. Returns the 1-based index where the iteration which is identified by the loop variable name currently stands. For the 0-based index, use the index built-in. Tells if the item where the iteration which is identified by the loop variable name currently stands is not the last item.
If you need the inverse of this built-in, use var? Returns the 0-based index where the iteration which is identified by the loop variable name currently stands. For the 1-based index, use the counter built-in. Tells if the item where the iteration which is identified by the loop variable name currently stands has an even 1-based index. To make tables with alternating row colors and such, use var?
Tells if the item where the iteration which is identified by the loop variable name currently stands is the first item. Tells if the item where the iteration which is identified by the loop variable name currently stands is the last item.
Tells if the item where the iteration which is identified by the loop variable name currently stands has an odd 1-based index. It also allows more than 2 values that it will cycle through. Returns "odd" or "even" string value, depending on the parity of the 1-based index where the iteration which is identified by the loop variable name currently stands. This is commonly used for alternating color for table rows:. Returns "Odd" or "Even" string value note the capitalizationdepending on the parity of the 1-based index where the iteration which is identified by the loop variable name currently stands.

FreeMarker is a "template engine"; a generic tool to generate text output anything from HTML to auto generated source code based on templates. It's a Java package, a class library for Java programmers. It's not an application for end-users in itself, but something that programmers can embed into their products.
Otherwise simply copy freemarker. For example, if you are using FreeMarker in a web application, you probably want to put freemarker. FreeMarker has no required dependencies. It has several optional dependencies, but usually you don't have to deal with them, because if you are using an optional feature that's certainly because your application already uses the related library.

Then, Apache FreeMarker displays that prepared data using templates. In the template you are focusing on how to present the data, and outside the template you are focusing on what data to present. This approach is often referred to as the MVC Model View Controller pattern, and is particularly popular for dynamic web pages. Designers won't face complicated logic in templates, and can change the appearance of a page without programmers having to change or recompile code.Tesla investor reddit
It's used in non-web application environments as well. Powerful template language: Conditional blocks, iterations, assignments, string and arithmetic operations and formatting, macros and functions, including other templates, escaping by default optionaland many more.
Multipurpose and lightweight: Zero dependencies, any output format, can load templates from any place pluggablemany configuration options. Versatile data-model: Java objects are exposed to the template as a tree of variables through pluggable adapters, which decides how the template sees them.

In this post, we will examine three particular FreeMarker expressions that can each be used on standard text within your email or on text that is dynamically inserted from a record in your CRM, providing a greater degree of control over how text displays in our emails: split, capitalize and lowercase.
The FreeMarker split function allows you to divide a string of text along the occurrences of a secondary string or character and is used with the FreeMarker list function. The split function looks like this:. The output for this example would be:.
What is Apache FreeMarker™?
Note that the split function will split the string at every instance of secondary string that it finds, so if, for example, the previous string looked like this:. The FreeMarker I want to use looks like this:. When I add this into my email and send it to myself, I receive the following results in my inbox:. The first line shows how the data displays when I reference the Products field directly, and the rest of the text is how the Products field displays when using the split function. Capitalize and lowercase are similar functions that are both a bit more straightforward than split.How To process Templates Using Java - free marker
The capitalize function capitalizes the first letter of each word in a given string. For example, the function below:. While they are not particularly flashy, these functions can be used to ensure consistency in the formatting of dynamic content that you display to customers in your emails.
This could be helpful to account for any typos made when inputting data or for cleaning up text that customers submit in a form. FreeMarker expressions can be stacked, so both of these items could even be combined if you wanted to format text and also display it as a list. View Larger Image. Split Function The FreeMarker split function allows you to divide a string of text along the occurrences of a secondary string or character and is used with the FreeMarker list function.Maltipoo puppies for sale in tupelo ms
The output for this example would be: — some — test — text Note that the split function will split the string at every instance of secondary string that it finds, so if, for example, the previous string looked like this: Some,test,text The output would be: — some — — test — text The blank list item is the result of the two adjacent commas.
When I add this into my email and send it to myself, I receive the following results in my inbox: The first line shows how the data displays when I reference the Products field directly, and the rest of the text is how the Products field displays when using the split function.
Capitalize and Lowercase Functions Capitalize and lowercase are similar functions that are both a bit more straightforward than split. Happy Marketing!

We introduce the FreeMarker template engine and create several console and web applications. Maven is used to build our examples. NetBeans is used to manage the applications. FreeMarker is a template engine for the Java programming language. FreeMarker's home page is freemarker. A template engine combines static data with dynamic data to produce content.
A template is an intermediate representation of the content; it specifies how the output will be generated. FreeMarker is not restricted to templates for HTML pages; it can be used to generate e-mails, configuration files, source code etc. The first two applications are console applications. They use the following Maven build file:. FreeMarker will replace an interpolation in the output with the actual value of the expression inside the curly brackets.
The example prints a simple text to the console. The final text was processed by a template engine. Configuration is used to set the FreeMarker settings; it takes the version of the FreeMarker library as a parameter. The setClassForTemplateLoading sets the class whose method will be used to load templates.
With the getTemplate method, we retrieve the test. The data model is created. The data from the model will be dynamically placed into the FreeMarker template file. The process method executes the template, using the provided data model and writing the generated output to the supplied writer. The test. This example is a Java console program, which uses FreeMarker to dynamically create a text output containing a list of cars.FreeMarker is a Java-based template engine which can be used in stand-alone or servlet-based Java programs.
In your Java program you supply the actual values for these placeholders and the final output is generated based on this input. The variable values can be simple strings, numbers and such primitive values, but also lists, maps, or arbitrary Java objects whose methods you can call from the template.
Note that when accessing JavaBean properties, myObject. The output of templates is written into a Writer that you provide, so it can go into a HTTP response for dynamic web pagesinto a local file, into a Stringetc. To use FreeMarker download the latest version of it from the following webpage and add it to the classpath of your Java project. FreeMarker code completion and syntax highlighting is part of the JBoss Tools.
Create a new Java project called com. Create a new folder called lib and add the Freemarker library to it. Add this library to the classpath for your project. Create a new folder called templates inside the folder of the com. Inside that, create the following file with name helloworld. When you find yourself copy-pasting common parts between templates a lot, you should probably use macros. Continuing our last example, create a new folder called lib inside the templates directory, and there create a file called utils.
Another way of reusing template fragments is moving the common fragment into its own ftl file. This is less flexible than macros, but simpler in concept: it mimics copy-pasting. FreeMarker requires you to provide an explicit default for variables, so avoid values that are null or undefined:.
You can also ask FreeMarker to add? Free use of the software examples is granted under the terms of the Eclipse Public License 2.How to remove scratches from amethyst

Introduction to FreeMarker FreeMarker is a Java-based template engine which can be used in stand-alone or servlet-based Java programs.But these are just special cases of the generic forms, which are shown below. Note that for simplicity we only show the generic forms for sequence listing; simply replace " as item " with " as keyvalue " to get the generic form for hash listing. Where: see the "Where" section of Form 1 above and thus the else part is optional here too. Assuming users contains the ['Joe', 'Kate', 'Fred'] sequence:.
The list directive executes the code between the list start-tag and list end-tag the body of list from now on for each value in the sequence or collection specified as its first parameter.
For each such iteration the loop variable user in this example will store the value of the current item. The loop variable user only exists inside the list body. Listing hashes is very similar, but you need to provide two variable names after the as ; one for the hash key, and another for the associated value.Strongest dinosaur in ark 2018
Note that not all hash variables can be listed, because some of them isn't able to enumerate its keys. It's practically safe to assume though that hashes that stand for Java Map objects can be listed. The else directive is used if when there are 0 items, you have to print something special instead of just printing nothing:. This outputs the same as the earlier example, except when users contains 0 items:. Note that the loop variable user doesn't exist between the else tag and the list end-tag, since that part is not part of the loop.
That is, you can't moved it out into a macro or included template. The items directive is used if you have to print or do something before the first list item, and after the last list item, as far as there's at least 1 item. A typical example:. That is, when the list directive has no as item parameter, the body of its is executed exactly once if there's at least one item, or not at all otherwise.
It's the body of the mandatory nested items directive that will be run for each item, and hence it's also the items directive that defines the loop variable with as itemnot list. A list directive with items also can have an else directive:. The parser will check that a list without as item parameter always has a nested items directive, and that an items directive always has an enclosing list which has no as item parameter.
This is checked when the template is parsed, not when the template is executed. Thus, these rules apply on the FTL source code itself, so you can't move items out into a macro or included template.
A list can have multiple items directives, but only one of them will be allowed to run as far as you don't leave and re-enter the enclosing list directive ; and further attempts to call items will cause error. So multiple items can be utilized on different if - else branches for example, but not for iterating twice. The loop variable user only exists inside the body of the items directive.
For example:. In the next example, you couldn't use such abbreviation HTML tags close nothing, as they are just raw text to output for FreeMarker :.
Thus, it can be used anywhere where there's a list or items loop variable available, it can occur for multiple times, and it can have arbitrary nested content. The parser ensures that sep is only used on a place where there's a visible loop variable.
This happens earlier than the actual execution of the template. Thus, you can't move sep from inside the associated list or items directive into a macro or included template the parser can't know where those will be called from. Instead, use sequence?
