Re: [Pharo-project] EvaluateCommandLineHandler changes

What if the fileIn is just joined at the end of the argument list for every handler? That way you will be able to do echo "-eval blabla" | Vm Image or echo blabla | Vm Image -eval ls | grep fuel | vm image On Thu, Jun 28, 2012 at 10:06 PM, Guillermo Polito < guillermopolito(a)gmail.com> wrote: > :3 great.

[Pharo-project] EvaluateCommandLineHandler changes

by Guillermo Polito

Hi Camillo, the latest introduction of this: "check if we have an opened stdin" FileStream stdin ifNotNilDo:[ :stream| stream atEnd ifFalse: [ ^ true ]]. (I assume for piping?) Is messing with my other command line args... lets say I have another command line argument that runs tests and I do: Vm image --tests It tries to open it with the EvaluateCommandLineHandler :S... Args is: an OrderedCollection('--test') And the command line handlers after selecting the responsibles are: an OrderedCollection(EvaluateCommandLineHandler RunTestsCommandLineHandler DefaultCommandLineHandler) By now I'll try putting my handler a higher priority (1 :P), but, is this the expected behavior?
