Chris Muller uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-cmm.719.mcz ==================== Summary ==================== Name: Morphic-cmm.719 Author: cmm Time: 22 January 2014, 4:45:41.605 pm UUID: fb0dbce6-b199-4d5e-a363-a20b09ef76a7 Ancestors: Morphic-cmm.718 Update "How to extend the system" workspace. - Mention and link to SqueakMap. - Mention and link to the package-definitions defined in Installer. - Remove the Seaside entries because they're old, don't work, and are redundant with the newer ones on SqueakMap (which do work). =============== Diff against Morphic-cmm.718 =============== Item was changed: ----- Method: TheWorldMainDockingBar>>extendingTheSystem (in category 'submenu - help') ----- extendingTheSystem + ^'SqueakMap is an integrated catalog of external applications for Squeak. It is accessible from the "Apps" menu. This catalog does not host the projects, it merely documents the load scripts required to correctly bring them into the image. - ^'"Note: Please edit this workspace and add your own contributions. - To submit it to the inbox open the Monticello browser and submit it from there. - Save the package ''* Morphic'' to the inbox." + Many SqueakMap packages use Installer, which defines several packages in its package-definitions protocol. Any of these can be loaded with an expression like the following: - "Updating your system: - The following will set the default update URL to receive development updates. - For developers and dare-devils only." + Installer new merge: #openGL - MCMcmUpdater defaultUpdateURL: ''http://source.squeak.org/trunk''. + Change #openGL to the selector name of the package you want to load. The latest version of that package and all of its prerequisites will be merged into the image. Merging a package is no different from loading it unless the package is already loaded, in which case it is upgraded to the latest version in a way that preserves any local changes you may already have made. - "Installing new packages: - The following expression show how to load many interesting packages into Squeak." + --------------- + This remainder of this workspace documents load-scripts for packages that are not documented in either SqueakMap or Installer. - Foreign Function Interface - ================== - Installer new merge: #ffi + OCompletion + "Provides source code completion as you type" - "OCompletion provides source code completion as you type" (Installer ss project: ''OCompletion'') install: ''Ocompletion''.

Item was changed: ----- Method: TheWorldMainDockingBar>>workingWithSqueak (in category 'submenu - help') ----- workingWithSqueak ^'Starting and Quitting + Like most Smalltalk''s, the machine-executable portion is a relatively small program known as the "virtual machine" (VM). 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. - Obviously you have figured out how to start the system. One way is to double-click on an image. If you have several different interpreters, you may want to drag the image to the appropriate interpreter; that lets you decide which interpreter should be used. + Smalltalk cannot run without the VM. The VM can''t do anything useful except process Smalltalk systems. - To quit a Squeak session, choose ''quit'' from the menu bar. If you save, your previous image file will be overwritten. You may choose ''save as...'' or ''save as new version'' to save a copy of your image and changes files with a new name (see below). + 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. - Image File - All of the objects -- classes, dictionaries, windows and other objects -- that make up the Squeak environment are stored in an image file (this must be named ''SomeName.image'' or ''SomeName.ima''). When you start up an image, everything is right where you left it when you last saved that image. + 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. - Sources and Changes - The source code associated with the Squeak code in an image file is stored in two other files. The code of the base system (e.g., Squeak version 4.1) is stored in the file ''SqueakV41.sources'', and the sources for methods added or changed since that time are in the changes file (which must similarly be named ''SomeName.changes''). + 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. - Storing the source code in a separate file has several advantages. To begin with, if you have been working for a couple of hours, and your dog pulls out the power cord, you will still have a sequential record of all your program edits, and these can be perused and replayed to recover your work. This feature has also saved many a hacker who got too adventurous while changing the system he or she was using. + When an image is started, every object resumes exactly from where it was last saved. - However, if you wish to run the system with severely limited resources, it can be operated without any source code, owing to its ability to decompile the bytecode methods into a readable and editable version of the original source code (only comments and temporary variable names are lost). + 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. - Finally, since the changes file does not consume memory space, Squeak keeps a complete history of all your 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. + 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. - FileOut, FileIn - In addition to the ''save'' command that saves the entire state of your Squeak image, individual methods, categories and classes may be ''filed out''. Filing out a method, category, or class results in the creation of a text file containing the code in question. This file can be read into the same or another Squeak image to recreate the saved classes and methods. + 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.. - ChangeLists, ChangeSets, and ChangeSorters - A ChangeList is a method-by-method view of a fileOut. Note that the changes file records all your programming actions using the same fileOut format, so a ChangeList can browse the change history of any Squeak image. The "recover changes" command of the Extras menu is one way to do this. You can also open a ChangeList on any fileOut file by selecting the file in the FileList and selecting the "browse changes" command. + 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. - In addition to the image-wide record of changes kept in the changes file, a record of changes is also associated with every project. This "change set" records only the class and method changes you made within that project. This allows you to make a fileOut of all the changes that constitute your work on that project. Single and dual ChangeSorters allow one to examine the change set of the current project and other projects, and also allows changes to be moved between change sets. These are very useful tools for more experienced Squeak programmers. + 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. - Organizing your Disk - Squeak will look for the sources file either in the folder containing the image. If the sources file is not found there, then it looks in the folder containing the VM. In general, it is simplest to keep a single copy of the sources file in the folder containing the VM. You can use any number of image/changes pairs anywhere on your disk. + 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! - If you wish to maintain several versions of the VM, here is the easiest way: place all VMs in one folder along with the sources file. Then, in each folder with images for version X, place an alias of the VM for version X. You can then start VM version X on that image by dragging the image onto the VM alias. (If you start Squeak by double-clicking on the image, it might use the wrong version of the VM to run that image.) Another technique is to keep an alias for your favorite VM on the desktop and start images by dropping them on this alias. These instructions apply to Mac and Windows, but the same general strategy can be applied to Linux, Unix, and many other platforms. - !! - ]style[(21 512 10 296 19 1397 15 366 42 983 20 1029)bu,,bu,,bu,,bu,,bu,,bu,!!' readStream nextChunkText!
