I need to work with long strings containing line breaks in Java. Those are for HTML generation, but it is not the most important here.
I’m aware Java is cripple in a way it doesn’t have heredocs. But there are other mechanisms I could use:
1) String concatenation (or StringBuilders), not very readable and copy-pasteable.
2) Storing strings in .properties files, either not very readable, but with higher copypasteability.
3) Storing each “heredoc” in seperate .txt file, quite readable and copypasteable, but resulting in a horde of txt files.
4) Template engines, like Velocity or Freemarker – moves design out of Java, requires a lot of map operations, it would be quite good, but the Velocity syntax and loop/if abilities aren’t as readable as for example those from Smarty
Each have pros and contras, I’d like to choose 3 but the management prefers 1 because of pure ideological reasons. I’d like to have some standard for working with heredocs in Java, possibly library that makes things easier. I’d be gratefull for any suggestions (with good arguments) how to work with heredocs.
Thanx
Try Rythm template engine, which is built as a high performance Java template engine with Razor like clean syntax.
