java - Limit string length in FreeMarker -


I am trying to get a substrings from string in FreeMarker. Although there are 2 lemons to consider:

  1. The string may be blank
  2. The string may be less, the length of the maximum string

I do the following: 

  & lt; #list Landing Page 1.popular; As a line & gt; & Lt; Li & gt; & Lt; Span class = "minititle" & gt; & Lt; #assign minititle = (row.title! "") & Gt; & Lt; #if Minute Length & amp; Lt; 27 & gt; $ {Minutes} & lt; # Else & gt; $ {Minititle? Substring (0,26)} ... and lieutenant; # / If & gt; & Lt; / Span & gt; & Lt; / Li & gt; & Lt; / # List & gt;

I get a freemarker error: 

  Failed to load template: Expected " ; Line 65 on Line 144, Landing Page 1. One in the Fort was expected: & gt; ATTEMPT & gt; ... & lt; IF & gt; ... & lt; LIST & gt; ... & lt; FOREACH & gt; ... & lt; SWITCH & gt; ... & lt; ASSIGN & gt; ... & lt; Glomacine & gt; ... & lt; LOCALASSIGN & gt; ... & lt; Include & gt; ... & lt; Import & gt; ... & lt; Function & gt; ... & lt; Macro & gt; ... & lt; Transforms & gt; ... & lt; Visit & gt; ... & lt; STOP & gt; ... & lt; Returns & gt; ... & lt; Call & gt; ... & lt; Settings & gt; ... & lt; COMPRESS & gt; ... & lt; COMMENT & gt; ... & lt; TERSE_COMMENT & gt; ... & lt; NOPARSE & gt; ... & lt; END_IF & gt; ... & lt; BREAK & gt; ... & lt; SIMPLE_RETURN & gt; ... & lt; HALT & gt; ... & lt; FLUSH & gt; ... & lt; TRIM & gt; ... & lt; LTRIM & gt; ... & lt; RTRIM & gt; ... & lt; NOTRIM & gt; ... & lt; SIMPLE_NESTED & gt; ... & lt; Nested & gt; ... & lt; SIMPLE_RECURSE & gt; ... & lt; RECURSE & gt; ... & lt; Fallback & gt; ... & lt; Escape & gt; ... & lt; NOESCAPE & gt; ... & lt; UNIFIED_CALL & gt; ... & lt; WHITESPACE & gt; ... & lt; PRINTABLE_CHARS & gt; ... & lt; FALSE_ALERT & gt; ... "$ {" ... "# {" ... ...

Very strange. Can anyone help?

After extensive testing, the error itself was resolved. Karma should be done.

My last code for secure detection: 

  & lt; #assign minititle = (row.title! "") & Gt; & Lt; #if Minute Length & amp; Lt; 27 & gt; $ {Minutes} & lt; # Else & gt; $ {Min? Substring (0, 26)} ... ... & lt; / # If & gt;

Hope this helps someone else

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
