Doesn't appear to support files with imports?
Closed this issue · 3 comments
Compiling a simple hello world .fr file with the plugin works fine for me. Problems arise when I try to use imports in the .fr files.
When I compile with the command line compiler using -make:
fregec -sp src/main/frege -fp build -make src/main/frege/Main.fr
I can compile the three files below without trouble. However, the sbt plugin always fails to compile them due to a class not found exception like this:
E [path]/src/main/frege/Main.fr:3: Could
not import package example.Hello (java.lang.ClassNotFoundException:
example.Hello)
E [path]/src/main/frege/Main.fr:4: Could
not import package example.Other (java.lang.ClassNotFoundException:
example.Other)
runtime 2.739 wallclock seconds.
[trace] Stack trace suppressed: run 'last compile:managedSources' for the full output.
last compile:managedSources gives this:
> last compile:managedSources

[error] (compile:managedSources) Frege compilation error
I have this structure:
src/main/frege:
Main.fr
src/main/frege/example:
Hello.fr
Other.fr
Here are the contents of each:
Main.fr:
module Main where
import example.Hello
import example.Other
main = putStrLn "this is the main"
Hello.fr:
module example.Hello where
data Other = Any | Old
showOther :: Other -> String
showOther Any = "any"
showOther Old = "old"
main :: [String] -> IO ()
main _ = println "Hello, world!"
Other.fr:
module example.Other where
data Other = Any | Old
main :: [String] -> IO ()
main _ = do
putStrLn "This is the other"
Looks to me like sbt is not using (or propagating) the -make
option.
In that case you'd need to specify all source files in dependency order.
Or just use fregec directly for such a tiny thing.
This should be fixed in 0.5.0 -- give it a try and let me know.
project/plugins.sbt:
addSbtPlugin("com.earldouglas" % "sbt-frege" % "0.5.0")
Works! Thanks for the super-quick response!
