Module versions with unicode

[lucaswerkmeister]

cd /tmp
ceylon new hello-world hello-world --ant=false --eclipse=false --module-name=tmp --module-version=version
cd hello-world/
ceylon compile tmp
ceylon run tmp/version
# Note: JBoss Modules version 1.1.3.GA 
# Hello, World!
sed -i 's/version/vερσiον/' source/tmp/module.ceylon
ceylon compile tmp
ceylon run tmp/vερσiον
# Note: JBoss Modules version 1.1.3.GA 
# ceylon run: Invalid module name or version: contains invalid characters

That message is printed here.

If you try to create that version directly with ceylon new, you get this instead:

ceylon new hello-world hello-world-2 --ant=false --eclipse=false --module-name=tmp --module-version=vερσiον
ceylon new: Invalid value: vερσiον
java.lang.RuntimeException: Invalid value: vερσiον

Found around here. @tombentley here’s your issue, I used the repository that contains the error message.

Thanks for hunting that down @lucaswerkmeister. It looks like it's a limitation inherited from JBoss modules, which is using regexes with the a-z and A-Z character classes. I guess there isn't any reason why unicode categories couldn't be used, but we'll need to get that into JBoss modules in order to remove this limitation.

[tombentley]

\p{Alnum} is probably more appropriate, for example.

[lucaswerkmeister]

What are the technical restrictions to the version anyways? I get that the module name needs to be a valid Java identifier because it’s part of the package names, but as far as my knowledge goes, the version is a String only used in file names and could be almost arbitrary…

[lucaswerkmeister]

Oh and by the way, a module called τμπ compiles just fine and gets the same error when ran.

[tombentley]

I've opened https://issues.jboss.org/browse/MODULES-190, so we'll see what they say.

[FroMage]

Wow, they only ever had 189 bugs? That must be solid technology ;)

[tombentley]

This has just been fixed in jboss module's upstream: https://issues.jboss.org/browse/MODULES-190

[FroMage]

Err, didn't we move that issue?
