Dump entire fcl configuration - twongjirad/LArLiteSoftCookBook GitHub Wiki

After having setup a larsoft environment, you can use

ART_DEBUG_CONFIG=1 lar -c my.fcl

to dump out the entire configuration. You can see what's the values actually being sent to your program.

Note the configuration is going to be yuge. It is best to pipe it into a file (the config comes from standard error)

ART_DEBUG_CONFIG=1 lar -c my.fcl >& foo.txt
