Struture

1. [Macro implementations] (macros/src/main/scala)
2. Calling macros
3. Powerpoint presentation

Basic demo: Windows

1. Build and run the project with cleanrun.bat
2. See the macros have ouputed something
3. Run it it again with run.bat
4. Notice there is less output - it is already compiled so macros did not run
5. Look at the decoded bytecode in Main.class.decoded.txt
6. The text file has been loaded in as a String constant see here
7. See the generated code for creating the map see here
8. You can generate this file with decode-main.bat. Note: <path-to-jdk>\bin must be in PATH

Basic demo: Linux

If you do not have sbt installed already you can use java -jar sbt-launch.jar in place of sbt.

1. Build and run the project with sbt clean run
2. See the macros have ouputed something
3. Run it it again with sbt run
4. Notice there is less output - it is already compiled so macros did not run
5. Look at the decoded bytecode in Main.class.decoded.txt
6. The text file has been loaded in as a String constant see here
7. See the generated code for creating the map see here
8. You can generate this file with sh decode-main.sh Note: requires a JDK installed.
