Currently my travis repoman runs can fail because of missing console output. A spinner option as it is already existing for the emerge command would fix this. Please add such an option to repoman.
Well, I've just started a slice and dice operation on repomans structure and code. It is also looking like (so far) I will be using the plugin system from emaint. It may be quite possible to optionally turn on a progress bar (reusing the one from emaint). There is no guarantee that all modules will be able handle a progress bar. It is also too early in the rewrite process to know. It is also my goal to make the code have decent API's, so it should be quite possible to run repoman from a django webpage and get data returned from it's modules without the need to parse terminal output.
repoman support has been removed per bug 835013. Please file a new bug (or, I suppose, reopen this one) if you feel this check is still applicable to pkgcheck and doesn't already exist.
