[Snowball-discuss] Multiple errors in generated Java sources for Latin algorithm

[Alexander Myltsev]

Hi,

I’m trying to generate Java sources for http://snowballstem.org/otherapps/schinke/ algorithm. I added stem.sbl from schinke.tgz to “snowball/algorithms/latin/stem.sbl” sources. Then updated GNUmakefile:

diff --git a/GNUmakefile b/GNUmakefile
index d6c7606..08237fa 100644

Apparently generated sources are not compiled against 

java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

with error:

[error] ./src/main/java/org/tartarus/snowball/ext/latinStemmer.java:260: missing return statement
[error]     } 

Even if I stub the error with `return true` or `return false`, stemmer produces weird results. When I launch `TestApp latin in.txt –o out.txt` for input `datum` it produces string `datum                    datum`, but should just `dat`.

Does anybody know how to make Latin algorithm work?
