What do you think is a good IDE for learning SmallTalk? I'll only be using it as a hobby, so it has to be free. I think Squeak is the way to go. It has an entire smalltalk environment and is constantly updated. Its what I used for learning and is actually even a cool app in itself. You should also consider Pharo . Pharo is a fork of Squeak. Their goals are: a clean and lean open-source Smalltalk platform, derived from

In case of not having support, how can I detect at which level is missing (VM, font, Converter, etc)? 回答1: At the VM level you can try Character codePoint: 256 or Character codePoint: 65536 (some Smalltalks may use value: instead of codePoint: still). Converter APIs differ between dialects too, but chances are that if the VM supports Unicode so will the converters. As far as I know, no Smalltalk fully supports Unicode algorithms (case-folding,

编译型语言是编译一次就可以转成计算机可以直接运行的机器语言程序（如.exe文件）但是由于他们是直接编译的，依赖于计算机的不同，所以跨平台能力比较差，但是运行速度高。 解释性语言则是每次运行前编译，先解释再运行，导致运行效率降低，但是因为其依托于虚拟机/解释器所以跨平台性能好。 高级语言还可分为面向过程语言和面向对象语言。（区别自然是有没有对象） 于 1967 年出现的 Simula67 是历史上第一个面向对象语言 Smalltalk 被公认为第二个面向对象的程序设计语言，和第一个IDE C 和 Pascal 是纯面向过程语言 就算没有对象也可以学面向对象的程序设计语言 C++ 第一个高级语言是fortran，Ada是美国军方发明的语言，取名Ada是为了纪念第一个女程序员 第一个支持面向对象的语言是simula67 1 、 （ NOIP - 2004 T19 -多选）下列哪个（些）程序设计语言支持面向对象程序设计方法（ ABDE ）。 A .

I've got rather distinct question - I'd like to run Smalltalk on a production server without using graphical interface. Is this possible with VW or Pharo (maybe even Squeak)? I've got a VPS hosting without X and would like to have few websites running on Smalltalk, while developing them locally with full-blown Smalltalk env, including GUI. Mariano Martinez Peck Yes, it is possible to deploy Pharo in a "headless" way. Just send the -headless and that's all. Example: #!/bin/sh NOHUP="/usr/bin/nohup" SQUEAK_VM="/usr/bin/squeakvm" SQUEAK_OPTS="-mmap 100m -vm-sound-null -vm-display-X11 -headless"

What are the key differences between OO in Smalltalk and Java? Please note that I am a Java programmer trying to expand his horizons by exploring Smalltalk. Currently I know almost nothing about Smalltalk except that it's purer than Java. Therefore I'll prefer the answer that shows how various Java concepts map to corresponding Smalltalk concepts and then introduces the Smalltalk concepts that don't exist in Java at all. Frank Shearar Message passing Smalltalk uses message passing, not method invocation. The distinction is subtle, but enormously powerful. Some terminology: Given foo bar: baz ,

|a b | a := ZnClient new. a get: 'http://cloud-storage.com/login'. a formAt: 'username' put: 'jom'; formAt: 'password' put: 'mypass'; post; get: 'http://cloud-storage.com/my-file'. "Here I want to refresh the session for every 60sec and" "to checking for newer data" b := a maxNumberOfRedirects:60 Transcript show: b; cr. I would like to implement a method that can refresh the ZnClient session every 60s for checking for newer data on the server I am logged into. I tried the redirect method of pharo but it does not seem to work. or say It does not show anything. Any idea? | session data | session

I am trying to write a isBinary function that checks sent line if it has any non-printable characters (integer value outside range 0-127): isBinary := [ :sline | 'Reached isBinary fn.' displayNl. sline do: [ :char | "for each character" i := char asInteger. "convert to integer" (i < 0 | i > 127) ifTrue: [^true]. ]. "return true if found unprintable" ^false. ]. "if not found above, return false" (Directory working: '.') allFilesMatching: '*.x' do: [ :ff | ((ff name), ' : ') display. infile := FileStream open: ff name mode: FileStream read. firstline := infile nextLine.
