Inherit whitespace when invoking tags? about jte HOT 6 CLOSED

Hey @mtdowling, this isn't possible at the moment. Every template is precompiled independently from where it is called from. For rendering Html this isn't an issue, which is the primary use case of jte (for me). For Html, I'd love to add compile-time Html compression as a feature some day: #10

I added an experimental mode to trim the jte control structures from the output (TemplateEngine#setTrimControlStructures), that tries to remove extra indentations by jte control structures like @if, @for and so on. But that's still very experimental. And it doesn't solve the problem you describe.

May I ask what type of content you'd like to generate with jte?

My use case is code generation, so whitespace is super important for me. Thanks for clarifying.

You're welcome. Yeah, I think for perfect control over whitespaces jte is not the right tool. I did some improvements to #10 over the weekend, but the moment you extract functionality in a tag the whitespaces will be different.

Was about to open an issue for the same reason as this one. Glad I didn't.

I see a lot of potential in JTE for general code generation, but some languages are very indentation-sensitive (e.g. YAML, Python and even Scala 3).

@casid when you said:

Yeah, I think for perfect control over whitespaces jte is not the right tool.

You meant "at the current state but maybe in the future it will be" or "it's not intended for such use cases"? 😁

If you meant the former, we could discuss and I could help implement it (maybe even in a manner that also advances the implementation of #10).

from jte.

It is not really intended for perfect white space control. The reason jte was created was primarily to renderer HTML as fast and secure as possible. In order to carry indentations over to tags, we'd somehow need to pass that as a parameter to the tag. That tag indentation would need to be evaluated at runtime and that will add unnecesary overhead to HTML rendering.

I see. Thanks for the explanation!
