## Parser Input
|
||||
|
||||
CommonTokenStream
|
||||
(Scanner Output)
|
||||
|
||||
## Parser Output (AST)

Compiled Classfile
|
||||
|
||||
public class javaFileInput.Example {
|
||||
}
|
||||
|
||||
## E2E Tests:
|
||||
|
||||
- Testdatei mit Main ausführen/kompilieren
|
||||
- Testdatei mit "javac -d output .\CompilerInput.java" kompilieren
|
||||
- -> Dateien mit javap vergleichen
|
||||
|
||||
wenn beides erfolgreich
|
||||
|
||||
- Ergebnis vom eigenen Compiler mithilfe von main.EndToEndTester ausführen
|
||||
- (Ergebnis von javac mithilfe von main.EndToEndTester ausführen)
|
||||
|
||||
### Andis Tipps:
|
||||
|
||||
- cp mitgeben
|
||||
- makefile
|
||||
- java -jar pfadtocompiler.jar EmptyClass.java
|
||||
- mvn package
|
||||
- javac tester // tester compilen
|
||||
- java tester // tester ausführen
|
||||
- -> tester ist in unserem Fall main.EndToEndTester.java
|
||||
- -> Hab ich alles umgesetzt
