SemanticDB
To run the tests use two terminals. In the first terminal compile the
semanticdb/input project whenever sources change in
semanticdb/input/src/main/scala/**.scala.
cd semanticdb/input
sbt
> compile
In the second terminal, run sbt dotty-semanticdb/test from the main dotty
build
sbt
> dotty-semanticdb/test
The tests assert that the TASTy to SemanticDB converter produces the same output as the semanticdb-scalac compiler plugin. Test failures result in diffs like this
Test dotty.semanticdb.Tests.testExample failed: java.lang.AssertionError:
--- tasty
+++ scala2
-class Example {
- val a: String = "1"
+class Example /*example/Example#*/ {
+ val a /*example/Example#a.*/ : String /*scala/Predef.String#*/ = "1"The lines starting with - are the output from the TASTy converter and the
lines starting with + are the output from the semanticdb-scalac compiler
plugin.
Once the TASTy converter is updated to emit correct SymbolOccurrence
(https://scalameta.org/docs/semanticdb/specification.html#symboloccurrence) then
the "tasty" output should become identical to "scala2" and include inline
comments class Example /* pkg/Example# */. The inline comments are read as:
"the symbol pkg/Example# was resolved next to the class name Example".
