Here is a brief introduction to those elements: - - Projects - A project is an entire Squeak desktop full of windows. Projects are can be used to change quickly from one task to another. An inactive project is represented by a project window that shows a thumbnail of that project''s windows. Project windows are actually more like doors than windows, since you can enter the project just by clicking on its project window. You can create a new project by choosing ''open...project'' from the screen menu. To exit a project (and return to its parent project), choose ''previous project'' from the screen menu. Each project maintains its set of windows, plus its own set of Smalltalk changes and its own screen color depth. - - Morphic Halos - In a morphic project, cmd-click (alt-click) on a window or other graphical object will bring up a constellation of colored circles called "halo handles" around that object. Additional clicks will cycle through the halos for other graphical objects in the nesting structure. If you hold down the Shift key while cmd-clicking, the nested morphs will be traversed from innermost outward. Clicking without the cmd (alt) key will dismiss the halo. While the halo is up, letting the cursor linger over one of the halo handles for a few seconds will cause a balloon to pop up with the name of that handle. Three useful handles are the top-left "X" handle (delete), the bottom-right yellow handle (resize), and the brown handle (slide the object within its containing object). Halos allow complex graphical objects to be explored--or even disassembled (using the black halo handle). Usually no harm results from taking apart an object; you can just discard the pieces and create a new one. - - Flaps - To enable Flaps, click on the desktop to show the world menu, choose the "Flaps..." menu and "show shared tags". Tabs labeled "Squeak", "Tools", "Supplies", etc., will appear along the edges of the Squeak desktop. Click on any tab to open the corresponding flap. Drag a tab to resize the flap and to relocate the tab. Bring up the halo on any tab and click on its menu handle to be presented with many options relating to the flap. Use the "Flaps..." menu, reached via the desktop menu, to control which flaps are visible and for other flap-related options and assistance. - - Parts Bins - You can obtain new objects in many ways. The "Objects Catalog" (choose "objects'' from the world menu or open the objects flap) and several of the standard flaps (e.g. "Tools" and "Supplies") serve as "Parts Bins" the for new objects. Drag any icon you see in a Parts Bin and a fresh copy of the kind of object it represents will appear "in your hand"; click to deposit the new object anywhere you wish. You can also add your own objects to any of the flaps -- just drag your object over the tab, wait for the flap to pop open, then drop the object at the desired position in the flap. - !! - ]style[(123 9 663 13 991 5 579 10 589),bu,,bu,,bu,,bu,!!' readStream nextChunkText!

The VM''s job is to provide services from the physical machine to real Smalltalk objects. Services like input and output. The Smalltalk system, including all data and code, is a system of objects, built from the ground up, and interpreted by this virtual computer. This affords Smalltalk system platform portability. - - Smalltalk cannot run without the VM. The VM can''t do anything useful except process Smalltalk systems. - - To start the system, drag the ".image" data file to the VM executable "squeak". There are myriad command-line options for starting the system via the command-line (see squeak --help). By default, the system will open on the screen in a single OS window. - - To quit a Squeak session, choose ''quit'' from the menu bar. If you save, the image file will be overwritten and resume from that place the next time it''s launched. - - The Image File - Squeak is an environment built in its own objects from the ground up, including one or more end-user applications. All of the objects in the system -- Classes, Dictionaries, Windows, Customers and other objects that make up the Squeak environment are stored in a binary ".image" file. This is the "object-data file" loaded by the VM when Squeak is launched. - - When an image is started, every object resumes exactly from where it was last saved. - - The Sources File - Smalltalk is traditionally includes the source code in the running system. However, keeping multiple copies of the same source code in all images files is wasteful. Therefore, the source code itself is kept in a read-only .sources file and accessed by all images. The image files merely have pointers into this file, which is read on-the-fly to present original source code. - - The code of the base system is stored in the file "SqueakV41.sources". This file does not change except between releases of Squeak. Normally this file should be placed in the folder containing the VM executable. - - The Changes File - The purpose of Squeak is to develop new programs and systems. Code changes to the running system are effective immediately. But since multiple images can be running, they cannot all update the .sources file safely. Therefore, each image file is accompanied by a ".changes" file which contains source code changes for that and only that Smalltalk system.. - - The changes file is important for project work. It keeps a sequential log of development activity for the purpose of recovering work performed since the last image-save. Any of several events could lead to the need to recover work, including a power-outage or making an erroneous change to code required to keep the system running. - - The changes file does not consume memory space, so Squeak is able to keep a complete history of all program changes. This makes it easy to examine or even reinstate older versions of methods (see ''versions'' option in browser selector pane). This encourages experimentation, since you can easily revert to the original versions of any set of methods. - - In extreme cases where sources and/or changes files are not available, the system can still run, and will automatically decompile the bytecode methods in image memory, if necessary, into readable and editable versions of the original source code (only comments and temporary variable names are lost). - - Transferring Code-Snippets Between Images - In addition to the ''save'' command that saves the entire state of the system, the code of individual methods, categories or classes may be ''filed out'' and then filed-in to another image. - - Packages - The code of an entire project is encapsulated by a Package. This allows users to share their code with other users. Code of packages are delineated by the categories of their classes, and methods. The Monticello browser is then used to wrap that code into a Package object which can be saved to a Monticello repository at http://ss3.gemtalksystems.com/ss. - - Some projects end up using the resources provided by several packages, resulting in a hierarchy of packages that make up a system. Installer can be used to install such systems.!! - ]style[(21 970 14 448 16 396 11 188 16 321 4 1025 41 188 8 52 10 55 2 420)bu,,bu,,bu,,u,,bu,,u,,bu,,bu,,i,,i,!!' readStream nextChunkText!

Whenever you have an expression, like "3 + 4", you press cmd-i to "inspect it", which opens an inspector on the result. This works in any text area. Try for example inspecting "self" in a class browser, and you will inspect the underlying class object (which the browser shows a high-level view of). - - In the Inspector you see the objects referenced by this object (via instance variables or indexed fields) in the left panel. Select any of them and choose "inspect" from the context menu (or press cmd-i again). This way you can inspect all the objects in the system. - - A more modern tool than the Inspector (which was around 40 years ago already) is the Object Explorer. It presents you a tree view of an object and its "children", which again are the instance variables and indexed fields of the object. Open it with cmd-shift-i (or "explore" in the context menu). - - You can also do the reverse. If you choose "objects pointing to this value" you get an inspector showing all the objects that directly point to this object. Similarly there is a "reverse explorer", which you can open by selecting "explore pointers". - - There are two roots to all the objects in the system: - - Smalltalk specialObjectsArray - - which basically holds everything the Virtual Machine needs to know about, and in turn almost every object in the whole image, and - - thisContext - - which is the current execution context, holding onto temporary objects. When a garbage collection is performed, any object not reachable form either of these two roots is removed from memory. - - An "interesting" global object to explore is - - Project current - - which holds your current workspace, in particular - - Project current world - - , the root of all morphs in the world. And of course - - Smalltalk - - itself is the dictionary that holds all global objects, including all classes (unless they are defined in a non-global environment). - - There is also a low-level way to enumerate all objects in memory. "self someObject" will return the very first object in memory (which happens to be the nil object), and "anObject nextObject" will return the next one: - - | object count | - count := 0. - object := self someObject. - [0 == object] - whileFalse: [count := count + 1. - object := object nextObject]. - count - - Interestingly, this also finds objects that are due to be garbage-collected. For example, if you accidentally closed a text window, there is a good chance its contents will still be in memory, and can be retrieved using an expression like - - ByteString allInstances last: 10 - - This makes use of the someInstance/nextInstance methods, which are similar to someObject/nextObject, but restricted to instances of one class only. - '!

This tutorial demonstrates the fundamentals with a straightforward approach where code can be tested right away either here or in a Workspace window. The beauty of Squeak Smalltalk resides in the possibility to evaluate, inspect, print and debug code anywhere and this window is no different. - - This tutorial demonstrates how to... - - * retrieve an XML document from the World Wide Web - * instantiate an XML document class - * inspect and understand the content of an XML document - * retrieve and display values from specific XML tags - - Retrieve an XML document from the World Wide Web - - There are many manners to retrieve data from the World Wide Web in Squeak Smalltalk. HTTPClient is among them and allows to download files in all simplicity. Select the following code snippet and inspect it (press alt-i). An Inspect window will open with the document loaded in memory. The result is a MIMEDocument object. - - HTTPClient httpGetDocument: ''http://source.squeak.org/trunk/feed.rss''. - - TIP: Select HTTPClient and browse it (press alt-b) to open a System Browser window on its class. HTTPClient does not have instance methods but it has class methods. Click on class to see class methods. - - Instantiate an XML Document - - An instance of MIMEDocument will not allow to retrieve XML data in a comprehensive manner because it does not understand the nature of XML. For this reason, it is necessary to parse the content of MIMEDocument using XMLDOMParser. XMLDOMParser>>parseDocumentFrom: requires a stream as a parameter and ReadStream will be used for this purpose. The following code snippet instantiates an XMLDocument using the content of the downloaded file. - - | doc | - doc := HTTPClient httpGetDocument: ''http://source.squeak.org/trunk/feed.rss''. - XMLDOMParser parseDocumentFrom: (ReadStream on: (doc content)). - - Inspect and understand the content of an XML document - - XML is a flexible document format and it is necessary to understand how each given XML file is structured in order to properly search, retrieve and manipulate data. Inspecting values is critical in a dynamic programming language and environment, such as Squeak Smalltalk. Select the previous code snippet and inspect it (press alt-i). - - Unfortunately, the Inspect window does not reveal a lot about the XML structure of the downloaded file. Select the previous code snippet once again and explore it (press alt and the capital letter i). An Explorer window will open with a tree outline on the instance of XMLDocument. - - The Inspect and Explorer windows tell a lot about an XMLDocument. The sections are instance variables and their values are displayed aside. In the Explorer window, unfold elementsAndContents. Unfold other sections as deemed necessary to understand the XML format and the data available. - - The gibberish coding is about to become clear. Open a Browser window from the world menu and right click in the first pane, select find class (press alt-f) and type XMLDocument to search for its class, or select the class name and browse it (press alt-b). However, it is suggested to read more about XMLParser and XMLParserTest first. - - Retrieve and display values from specific XML tags - - The downloaded XML file contains a list of items which are denoted by the tag name "item". The Explorer window revealed the content of interest is located at the array index 1 of the elementsAndContents, which can be accessed through XMLDocument>>root. - - TIP: Some XML documents have additional components contained within its file, such as XMLPI (XML Processing Instructions). For this reason, the root may lead to this rather than the data which will be indexed at 2 or more. It is necessary to use XMLNodeWithElements>>elements, e.g. (xml elements at: 2), in order to access subsequent data. - - The following code snippet will display items in a Transcript window. Open a Transcript window using the world menu before selecting and executing the code. Select the code snippet and execute it (press alt-d). - - | doc xml | - doc := HTTPClient httpGetDocument: ''http://source.squeak.org/trunk/feed.rss''. - xml := XMLDOMParser parseDocumentFrom: (ReadStream on: (doc content)). - xml root tagsNamed: #item do: [:e | - Transcript show: (e asString); cr. - ]. - - An XML item looks like this: - - <item> - <title>HelpSystem-Core-tbn.46.mcz</title> - <link>http://source.squeak.org/trunk.html</link> - <description>throw out pharo specific stuff since we are now integrated in squeak (and pharo too where squeak specific stuff was removed)</description> - <pubDate>Sun, 02 May 2010 20:23:49 +0000</pubDate> - <author>Torsten Bergmann <[hidden email]></author> - <category>The Trunk</category> - <enclosure length="27288" type="application/x-monticello" url="http://source.squeak.org/trunk/HelpSystem-Core-tbn.46.mcz"/> - <guid isPermaLink="false"/> </item> - - The following code snippet uses information learned, retrieves each comment and displays them in a Transcript window.
