[Pharo-project] Issue 3669 in pharo: Unified API for accessing stdio streams

Status: FixedWaitingToBePharoed Owner: stephane...(a)gmail.com Labels: Type-Squeak 1.3 New issue 3669 by stephane...(a)gmail.com: Unified API for accessing stdio streams http://code.google.com/p/pharo/issues/detail?id=3669 Levente Uzonyi uploaded a new version of Files to project The Trunk: http://source.squeak.org/trunk/Files-ul.96.mcz ==================== Summary ==================== it may be interesting for Coral and scripting.

All users should send #stdin, #stdout and #stderr to FileStream to access the streams. - MultiByteFileStream is used instead of CrLfFileStream. - CrLfFileStream class >> #new is now deprecated =============== Diff against Files-mtf.95 =============== Item was changed: StandardFileStream subclass: #CrLfFileStream instanceVariableNames: 'lineEndConvention' classVariableNames: 'Cr CrLf Lf LineEndDefault LineEndStrings LookAheadCount' poolDictionaries: '' category: 'Files-Kernel'! + !CrLfFileStream commentStamp: 'ul 12/26/2010 03:13' prior: 0! + This class is now obsolete, use MultiByteFileStream instead. + - !CrLfFileStream commentStamp: 'ls 11/10/2002 13:32' prior: 0! I am the same as a regular file stream, except that when I am in text mode, I will automatically convert line endings between the underlying platform's convention, and Squeak's convention of carriage-return only. The goal is that Squeak text files can be treated as OS text files, and vice versa. In binary mode, I behave identically to a StandardFileStream. To enable CrLfFileStream as the default file stream class for an entire image, modify FileStream class concreteStream . There are two caveats on programming with CrLfFileStream. First, the choice of text mode versus binary mode affects which characters are visible in Squeak, and no longer just affects whether those characters are returned as Character's or as Integer's. Thus the choice of mode needs to be made very carefully, and must be based on intent instead of convenience of representation. The methods asString, asByteArray, asCharacter, and asInteger can be used to convert between character and integer representations. (Arguably, file streams should accept either strings or characters in nextPut: and nextPutAll:, but that is not the case right now.) Second, arithmetic on positions no longer works, because one character that Squeak sees (carriage return) could map to two characters in the underlying file (carriage return plus line feed, on MS Windows and MS DOS). Comparison between positions still works. (This caveat could perhaps be fixed by maintaining a map between Squeak positions and positions in the underlying file, but it is complicated. Consider, for example, updates to the middle of the file. Also, consider that text files are rarely updated in the middle of the file, and that general random access to a text file is rarely very useful. If general random access with specific file counts is desired, then the file is starting to sound like a binary file instead of a text file.) !

I represent a Stream that accesses a FilePage from a File. One use for my instance is to access larger "virtual Strings" than can be stored contiguously in main memory. I restrict the objects stored and retrieved to be Integers or Characters. An end of file pointer terminates reading; it can be extended by writing past it, or the file can be explicitly truncated. To use the file system for most applications, you typically create a FileStream. This is done by sending a message to a FileDirectory (file:, oldFile:, newFile:, rename:newName:) which creates an instance of me. Accesses to the file are then done via my instance. *** On DOS, files cannot be shortened!! *** To overwrite a file with a shorter one, first delete the old file (FileDirectory deleteFilePath: 'Hard Disk:aFolder:dataFolder:foo') or (aFileDirectory deleteFileNamed: 'foo').

Apart from that we use a plain 1.1.1 image stripped with #cleanUpForProduction. * http://code.google.com/p/pharo/issues/detail?id=3498 This is the fix for the concurrency issue in linked list that kills your image. I would certainly add this one to 1.1.2 * http://code.google.com/p/pharo/issues/detail?id=3542 This one is "Add SmalltalkImage>>#gcBiasToGrow: and friends to core". It is not critical, but we use it to be able to modify the two additional GC params. * lastly we removed the duplicated methods from a trait in Behavior to make Lint tests pass (I think I posted that but I can't find it in the tracker right now).
