Re: [Pharo-users] Mongo with Voyage

I'm not sure what you mean with initialize. If you think about creating the collections in mongo then you have to do nothing. Collections are created automatically as soon as you access them the first time.

Hello. I'am using pharo 4.0 with external mongo database (mongolab.com) I have like 7 classes which are voyageRoot. I want to know if I will initialize mongo in each class or in which class I can implement it. Thanks

Re: [Pharo-users] Pier3 with latest Pillar?

For me, Pillar was a package in Pier, and Pier was a tool that I used for all my presentations, prototyping, and small or short-lived community and not-for-profit projects. I do not get why you cannot use Pharo for that. Le 17/11/16 Ã 02:04, Jupiter Jones a Ã©crit : > Hey Stephane, > >>> It would be nice to see Pillar return to being a cross platform project as well.

Which packages? > I also feel my smalltalk-ability isnât up to the standard of so many of the amazing people contributing, which makes me a little reticent to get involved in the more complex projects. You see fixing a comment or adding a test should be possible. Don't hide yourself behind this argument. >> I will see if the trait usage make sense and can be removed.

Their constraints are even greater since they have a large commercial install base supporting many platforms. Come on. Pharo too and we have far less ressources!!! > We should be able to be more flexible and dynamic > >> Because you see Pharo will use more and more slots because they are really really cool and powerful. >> What do you do with Pillar?

Ok then you can still use an old version of Pier and hope that others will do what you want. >>> Iâd like to see Pier get some love - itâs an awesome tool.

Is there any chance that the Smalltalk project could also move there? It would make it easier to fork and hack and make versions available to test before deciding what might be valuable pushed back to the core project. Why easier? You cannot produce a slice? Seriously I will not move pillar to github before Pharo has a fully working solution. And I will maintain pillar but I need time. > > Thanks for all your excellent work with Pillar - not to mention everything else! > > Have fun! > > Jupiter > >

Progress Bar with unknown state or showing animated gifs
by Peter UhnÃ¡k Nov. 15, 2016

Nov. 15, 2016

Hi, is there a way to have a progress bar with unknown state? e.g. https://i.stack.imgur.com/gz9GK.gif ProgressBarMorph / Job / SystemProgressMorph seem to be based around progress only. Alternatively, is it possible to (easily) display animated gifs? Thanks, Peter

Example for Spec FastTableModel
by lionelakue Nov. 15, 2016

Nov. 15, 2016

Hello I am looking for an example on how to use FastTableModel. So it could look like a table with column headers, and mouse actions (right-click, etc) if possible... I need the API for adding columns, headers and datasource. Currently I am working with MultiColumnList, FastTableModel but I can't make them look like tables finally. Thanks, Lionel -- View this message in context: http://forum.world.st/Example-for-Spec-FastTableModel-tp4923147.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

scope shadowing problem.
by CodeDmitry Nov. 14, 2016

Nov. 14, 2016

Is there a way to stop Pharo from preventing me from shadowing blocks? [:superenv | |env| env := Dictionary new. [:superenv | |env| env := Dictionary new. [:superenv | |env| env := Dictionary new. "..." ] value: env. ] value: env. ] value: nil. It says superenv name already defined, even though that is the whole point, I want to demonstrate dynamic links, eg: var env_get = function(env, varname) { var tenv = env; while (true) { if (tenv.hasOwnProperty(varname)) { return tenv[varname]; } else { if (tenv.superenv == null) { throw "no such variable" + tenv; } else { tenv = tenv.superenv; } } } }; (function(superenv) { var env = { 'superenv': superenv, 'one': 1 }; console.log(env_get(env, "one")); (function(superenv) { var env = { 'superenv': superenv, 'two': 2 }; console.log(env_get(env, "one")); console.log(env_get(env, "two")); (function(superenv) { var env = { 'superenv': superenv, 'three': 3 } console.log(env_get(env, "one")); console.log(env_get(env, "two")); console.log(env_get(env, "three")); })(env); })(env); })(null); in JavaScript and (defun env_get (env varname) (let ((tenv)) (setq tenv env) (loop (let ((val)) (setq val (gethash varname tenv)) (if val (return val) (let ((superenv)) (setq superenv (gethash 'superenv tenv)) (if superenv (setq tenv superenv) (return 'undefined) ) ) ) )) )) ((lambda (superenv) (let ((env)) (setq env (make-hash-table)) (setf (gethash 'superenv env) nil) (setf (gethash 'one env) 1) (print (env_get env 'one)) (print (env_get env 'two)) (print (env_get env 'three)) ((lambda (superenv) (let ((env)) (setq env (make-hash-table)) (setf (gethash 'superenv env) superenv) (setf (gethash 'two env) 2) (print (env_get env 'one)) (print (env_get env 'two)) (print (env_get env 'three)) ((lambda (superenv) (let ((env)) (setq env (make-hash-table)) (setf (gethash 'superenv env) superenv) (setf (gethash 'two env) 2) (setf (gethash 'three env) 3) (print (env_get env 'one)) (print (env_get env 'two)) (print (env_get env 'three)) )) env) )) env) )) nil) in Lisp. -- View this message in context: http://forum.world.st/scope-shadowing-problem-tp4923049.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
