Run Daffodil from the Command Line/Terminal

To run the daffodil you just compiled, you need to generate the start script and invoke it.

To do this, run the sbt command:

sbt stage

This creates the jars, doc, and the scripts that start the daffodil CLI from the command line.

They are generated in the daffodil-cli/target/universal/stage/bin directory. (Flip the slashes for the Windows path!)

There is a bash script for Linux (file name is just 'daffodil'), and a Windows script (named 'daffodil.bat').

If you put this directory on your PATH environment variable, then it is convenient to use from the command prompt.

If you have built everything successfully, and setup the PATH, then (e.g., on MS Windows):

$ daffodil.bat --help

The result of the above command should display several help options for the daffodil program.  If it doesn't, please make sure that you've followed all of the previous steps.

Here's an example that parses data, displaying XML output to the console.

$ daffodil.bat parse -s daffodil-test-ibm1\src\test\resources\test-suite\tresys-contributed\AB.dfdl.xsd daffodil-test-ibm1\src\test\resources\test-suite\tresys-contributed\AB006.in

If the above executes and prints out an infoset as a result, you've set up everything correctly and you're ready to start using Daffodil!

Here is the linux variations of the same command (same except slashes are flipped)

$ daffodil parse -s daffodil-test-ibm1/src/test/resources/test-suite/tresys-contributed/AB.dfdl.xsd daffodil-test-ibm1/src/test/resources/test-suite/tresys-contributed/AB006.in

If the above executes and prints out an infoset as a result, you've set up everything correctly and you're ready to start using Daffodil!
