Enhance s-ramp CLI property interpolation: support default values ------------------------------------------------------------------ Key: SRAMP-452 URL: https://issues.jboss.org/browse/SRAMP-452 Project: S-RAMP Issue Type: Enhancement Security Level: Public(Everyone can see) Components: Shell Reporter: Eric Wittmann Assignee: Eric Wittmann Fix For: 0.5.0.Final Currently the shell supports property interpolation so that variables can be used in CLI command files. This takes the following form (for example): {code} connect http://localhost:8080/s-ramp ${username} ${password} {code} The CLI can then be invoked like this: {code} sramp.sh -f path/to/cli.txt -Dusername=admin -Dpassword=adminp {code} This is good, but let's also support optional default values for the variables, like this: {code} connect http://localhost:8080/s-ramp ${username:admin} ${password:adminp} {code} This will continue to replace ${username} with whatever value is passed via -Dusername=blah. However, if -Dusername is *not* provided, then the default value of 'admin' will be used. This will result in more powerful CLI scripts with commands like this: {code} connect ${sramp.endpoint:http://localhost:8080/s-ramp} ${sramp.username:admin} ${sramp.password:adminp} {code}
