Xml Interpolation #151

Exciting stuff!
Is it a subproject so that it is published as a separate library? If so, is it a new library because it has new transitive depndencies (scalafmt, fastparse)? Could it just be included in scala-xml? Do you expect it will target other platforms, Scalajs or native, or is it just for the JVM? |
Hi @ashawley,
It is indeed a new library because it has a dependency on
It’s just a macro, it doesn’t have runtime code, then we don’t have to cross-publish. |
because of the circular dependency between scala-xml and the Scaladoc tool, scala-xml is built during the Scala bootstrap process, so we need to be careful about not breaking that. (although it would be better, and not that hard, to get rid of the circular dependency — it's just a piece of work that nobody has gotten around to doing) |
|
2.13 is a preview release, so it's just an attempt to support compiler development. This is a consequence of the circular dependency Seth mentioned. Not being able to build in 2.13 for the moment is not a deal breaker, IMO. |
Would you be willing to create an example xmlquote project (or projects) that depends on this new library and have it work on the various runtimes (JVM, native, JS) assuming it could. I know it would require sbt publishLocal from this repo on a version 0.1-SNAPSHOT, but that's ok. I've been meaning to review this by doing the above, but I just haven't gotten around to it. |
@adriaanm is now working on this |
the circular dependency went away in Scala 2.13 but idk, maybe this repo should stay focused on what it already does, and this new thing should live elsewhere? |
and, that seems like where the discussion stopped. so, closing |
This PR contains an implementation of a macro based XML interpolator that we developed at EPFL that aims to be a drop in replacement for XML literals.
Additionally to the test suite, we tested it against The Lift Web Framework. We rewrote XML literals occurrences in the projects using Scalafix and successfully ran the test suite.
We decided not to support XML interpolation in pattern position as we don't know how to rewrite:
I was not sure how to integrate it to this repository so I split the build into two subprojects:
scala-xml
andscala-xml-quote
