Levente Uzonyi uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-ul.517.mcz ==================== Summary ==================== Name: Morphic-ul.517 Author: ul Time: 29 January 2011, 1:29:48.539 am UUID: 8fc622a0-bd75-1445-b30f-dd525ec0f5bf Ancestors: Morphic-dtl.516 - avoid an annoying error which is possibly caused by a concurrency issue. It happens rarely (often if you're using RFB) when you press the backspace in a TextEditor. =============== Diff against Morphic-dtl.516 =============== Item was changed: ----- Method: TextEditor>>backTo: (in category 'typing support') ----- backTo: startIndex "During typing, backspace to startIndex.

If typing has not yet been opened, open it and watch for the first and third cluster. If typing has been opened, watch for the first and second cluster. Save characters from the first and third cluster in UndoSelection. Tally characters from the first cluster in UndoMessage's parameter. Delete all the clusters.

Levente Uzonyi uploaded a new version of Files to project The Trunk: http://source.squeak.org/trunk/Files-ul.97.mcz ==================== Summary ==================== Name: Files-ul.97 Author: ul Time: 24 January 2011, 3:59:59.143 am UUID: 6f9985b2-9bce-a145-a3d2-276a76ce1fa7 Ancestors: Files-ul.96 - removed previous stdio support code from StandardFileStream, migration is done in the preamble =============== Diff against Files-ul.96 =============== Item was added: + (PackageInfo named: 'Files') preamble: '"Migrate stdio handles and files from StandardFileStream to FileStream. Turn off encoding and reuse the streams if they are in use in the image for backwards compatibility." + (StandardFileStream classPool at: #StdioHandles) ifNotNil: [ :handleArray | + FileStream classPool at: #TheStdioHandles put: handleArray ]. + (StandardFileStream instVarNamed: #stdioFiles) ifNotNil: [ :stdioFiles | + FileStream classPool + at: #StdioFiles put: stdioFiles; + at: #EncodeAndDecodeStdioFiles put: false ]. + Smalltalk + removeFromStartUpList: StandardFileStream; + removeFromShutDownList: StandardFileStream'!

Provides a simple, platform-independent, interface to a file system. The instance variable rwmode, inherited from class PositionableStream, here is used to hold a Boolean -- true means opened for read-write, false means opened for read-only. 2/12/96 sw I implement a simple read buffering scheme with the variables defined in PositionableStream (which are unused in me otherwise) in the following way: collection <ByteString> or <ByteArray> This is the buffer. position <Integer> The relative position in the buffer. Greater or equal to zero. readLimit <Integer> The number of bytes buffered. Greater or equal to zero. Read buffering is enabled with #enableReadBuffering, disabled with #disableReadBuffering and it is enabled by default. The buffer is filled when a read attempt of an unbuffered absolute position is requested, or when a negative repositioning is made (with #position: with an argument < than the current absolute position) to an absolute position which is not buffered. In the first case, the buffer is positioned to the given absolute position. In the latter case the repositioning is made to the requested absolute position minus fourth of the buffer size. This means that further small negative repositionings won't result in buffer flushing. This is really useful when filing in code. The read buffer is flushed (#flushReadBuffer) whenever a write attempt is made. The buffer state is valid if and only if collection is not nil and position < readLimit.! - StandardFileStream class - instanceVariableNames: 'stdioFiles'!
