Re: [Pharo-users] Code Critics for unloaded projects

by AxiNat

Lukas, if that happened anytime soon it would make my life much easier hehe Is there a way I could help to give it a boost? Mariano, the reason I cannot load the package is that it may contain (either intentionally or not) harmful code. An .st file can contain arbitrary code that is going to be executed at load time, so it'd be really easy to hack the image: "Object compile: 'new'!", for instance ;) The solution you propose looks interesting, but I'm not sure I've completely understood it. Do you mean to run a new image, send it the project file to be filed in, have it run the critics on the loaded package, and get the output back to the original image? If so, that's a solution I've been thinking of, but it would spend too many resources. Even though I could always use a very light image, if only 5 users were to be working on the app at the same time I'm afraid the system would begin to suffer :( On a second thought, is there some smaller, simpler implementation of the SmallLint package? I wouldn't need to run all the tests, just a couple of them: Bugs, Intention Revealing, Miscelaneous and Unnecessary Code, and actually not even all the tests in these categories. Thanks a lot, I'm all ears :) Bernat. 2011/4/4 Mariano Martinez Peck <marianopeck(a)gmail.com> > Is not enough loading the classes but not showing them in the browser ? or > maybe not putting them in Smalltalk ? > > can you do kind of a fork (using OSProcess) of the proccess running image > which receives a .st file and in the new forked image you pass the .st in > startup, do a file in and then run code-critics? > > I am curious why you cannot load them hehehehhe > > > On Mon, Apr 4, 2011 at 11:41 AM, AxiNat <tibabenfortlapalanca(a)gmail.com>wrote: > >> Hi list, >> >> I have a pretty special need, which is to be able to run code critics on >> projects that have not yet been loaded into the image.

Re: [Pharo-users] Code Critics for unloaded projects

by Mariano Martinez Peck

Is not enough loading the classes but not showing them in the browser ? or maybe not putting them in Smalltalk ? can you do kind of a fork (using OSProcess) of the proccess running image which receives a .st file and in the new forked image you pass the .st in startup, do a file in and then run code-critics? I am curious why you cannot load them hehehehhe On Mon, Apr 4, 2011 at 11:41 AM, AxiNat <tibabenfortlapalanca(a)gmail.com>wrote: > Hi list, > > I have a pretty special need, which is to be able to run code critics on > projects that have not yet been loaded into the image.

Re: [Pharo-users] Code Critics for unloaded projects

by Lukas Renggli

Being able to run Code Critics on not loaded code would be a very nice thing, unfortunately it is not supported right now. We wanted to do the same in SqueakSource when we originally wrote the software, but we had to realize that a lot of the rules unnecessarily depend on the fact that the code is installed. It is still one of the todo items for the refactoring engine to make Code Critics completely runnable on the refactoring code model. As the Pharo code model is diverging more and more from the refactoring code model this is more likely to happen anytime soon.

Code Critics for unloaded projects

by AxiNat

Hi list, I have a pretty special need, which is to be able to run code critics on projects that have not yet been loaded into the image. For example, I need to browse an st file -or a squeaksource project- and before loading it I want to run critics on it, would this be possible somehow? If it looks like something noone would need to do, I understand. It's just that the project I'm working on is pretty particular... I've been exploring other possibilities but I'm afraid this is one of the few left for me to think of :( Thanks a lot in advance! Bernat Romagosa.

Hi Hernan, I am know the Transcript and it not what I need. I need to integrate some my Smalltalk stuff other application, to more specific, I have an application that will call Smalltalk to perform certain operations and then the calling application needs to know the result of the operations. I could implement this using a file, but I want to avoid files if possible, that is why I want to write to the standard output. Saludos!
