Re: [Pharo-users] Progress Bar with unknown state or showing animated gifs

by Peter Uhnak

Hmm, thanks. I can write it myself, that's not a problem. I am just surprised that there is no native support/lib... I'll see if I can do something about it.

Example for Spec FastTableModel

by lionelakue

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.

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

by Peter H. Meadows

Hey. Can someone check this for me? In Pharo5 do: Gofer new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration; loadDevelopment. Gofer new url:'http://www.smalltalkhub.com/mc/phm/PierLoadExperiment/main'; package: 'ConfigurationOfPierLoadExperiment'; load. ((Smalltalk at: #ConfigurationOfPierLoadExperiment) project version: #stable) load. Gofer new url:'http://www.smalltalkhub.com/mc/phm/PierLoadExperimentChanges/main'; package: 'ConfigurationOfPierLoadExperimentChanges'; load. ((Smalltalk at: #ConfigurationOfPierLoadExperimentChanges) project version: #stable) load. ZnZincServerAdaptor startOn: 8080. PRPierFrame registerAsApplication: 'pier' kernel: (PRKernel instanceNamed: 'pier'). (WAAdmin defaultDispatcher handlerAt: 'pier' ) exceptionHandler: WADebugErrorHandler . Then visit http://localhost:8080/pier Does it work? Is it loading the right things? (I didn't check the tests yet, and i don't really understand metacello or Pier, just playing by trial and error :), but if it works, maybe someone with more experience can turn it into a config that will load from catalog in Pharo6.

Pharo and Raspberry Pi

by Dimitris Chloupis

Hey guys Today I manage to setup my old Raspberry Pi 1 Model B . I was wondering if I can run Pharo on it and how to do this. Any ideas ?

scope shadowing problem.

by CodeDmitry

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.
