I will be as simple as possible , i have the below template.ftl
B E G L E I T Z E T T E L Intern
FUER DATEI: ${content.fileName}
--------------------------------------------------------------------------------
BELEGLOSER DATENTRAEGERAUSTAUSCH
ERZ. SYSTEM: ${content.system}
INITIATOR: ${content.initiator}
DATEI ID: ${content.fileID}
And i want to output :
B E G L E I T Z E T T E L Intern
FUER DATEI: FileName
--------------------------------------------------------------------------------
BELEGLOSER DATENTRAEGERAUSTAUSCH
ERZ. SYSTEM: SYSTEMX
INITIATOR: Initiator
DATEI ID: FileID
But what i get instead ... let's say for the above example is :
B E G L E I T Z E T T E L Intern
FUER DATEI: FileName
--------------------------------------------------------------------------------
BELEGLOSER DATENTRAEGERAUSTAUSCH
ERZ. SYSTEM: SYSTEMX
INITIATOR: Initiator
DATEI ID: FileID
In other words the column is not properly aligned
How can i fix this problem in FreeMarker :) ?
Here is the answer , i used something not very complex:
<#assign lineWidth = 80>
B E G L E I T Z E T T E L Intern
<#compress>FUER DATEI: </#compress>${content.fileName?left_pad(lineWidth-"FUER DATEI:"?length," ")}
--------------------------------------------------------------------------------
BELEGLOSER DATENTRAEGERAUSTAUSCH
<#compress>ERZ. SYSTEM: </#compress>${content.system?left_pad(lineWidth-"ERZ. SYSTEM:"?length," ")}
<#compress>INITIATOR: </#compress>${content.initiator?left_pad(lineWidth-"INITIATOR:"?length," ")}
<#compress>DATEI ID: </#compress>${content.fileID?left_pad(lineWidth-"DATEI ID:"?length," ")}
So let's take the 3 first lines of code :
<#assign lineWidth = 80>
B E G L E I T Z E T T E L Intern
<#compress>FUER DATEI: </#compress>${content.fileName?left_pad(lineWidth-"FUER DATEI:"?length," ")}
1. Firstly i assign a variable lineWidth which represents the maximum line width of the file.
2. Then for each line i eat all the spaces using <#compress>
3. Then i added the value and left added the needed spaces in a way that everything aligns right.
----- BOSS LEVEL BELOW - using functions -----
<#assign lineWidth = 80>
<#function createLine prefix value >
<#return prefix + value?left_pad(lineWidth - prefix?length," ")>
</#function>

${createLine("FUER DATEI:",content.fileName)}
