I'm trying to figure out how to use FreeMarker to generate a file like so:
The contents of /home/myuser/somedir are:
blah.txt
fizz.gif
buzz.jpg
widget.log
...from a template like so:
The contents of <%dir%> are:
<%contents%>
I read the excellent Vogella tutorial on FreeMarker, but not really sure how to put this all together: once I query the directory for its contents, how do I add each item to this list of <%contents%>
? Thanks in advance!
FreeMarker templates can only display what you give to them through the data-model (aka. the template context). After all, a template is an MVC View, not a general purpose program. So, create a List<String>
before you call FreeMarker, call it dirContents
or something, put that into the data-model, also the directory name, and call it dirName
, and then do something like:
<p>${dirName}:</p>
<ul>
<#list dirContents as entry>
<li>${entry}</li>
</#list>
</ul>
