An example for setting up an Eclipse project an running the TPL project

Download TPL.zip to some directory Extract files Download TPL.zip to some directory

Start a new Java project

Specify the TPL directory

Browse for the directory and choose it

Make sure you chose the right directory (not the sub-direcitory src/TPL) Click next

The folders tree should look like this

Click on the ‘Libraries’ tab Add the java_cup.runtime jar file

Choose the jar file from the lib sub-directory

Make sure the jar file is successfully added

Let’s change the default output directory from ‘bin’ to ‘classes’ Let’s change the default output directory from ‘bin’ to ‘classes’. This is done to match the output directory specified in build.xml

After change

Compiler signals an error because Lexer does not exist – we need to generate it

Open a command line and go to the TPL directory Run ant with the ‘scanner’ target

Now Lexer.java exists under src/TPL

Run ant with the ‘classes’ target to compile all sources Run Main on prog.tpl, specifying that the CLASSPATH should contain the /classes sub-directory and the java-cup-runtime jar file The scanner signals a lexical error in line 0 since it include a comment and TPL.lex does not identify comments as tokens (yet)
