File Outs: Can We Have Unix Line Endings?

Any reason not to? Tedious to continually do "%s/\r/\r/g"s on Mac to fix: TextStream subclass:^M#UCTextStream^MinstanceVariableNames: ''^MclassVariableNames: ''^MpoolDictionaries: ''^Mcategory: 'UFFA-Core'!^M! ----- Cheers, Sean -- View this message in context: http://forum.world.st/File-Outs-Can-We-Have-Unix-Line-Endings-tp4769721.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Trie in Pharo
by Stephan Eggermont July 25, 2014

July 25, 2014

I took a look at what would be needed to port the Cuis Trie to Pharo. Trie is a subclass of Collection, and expects at: aKey, not at: anIndex. That breaks the EyeInspector view. What interface expects the explorer a Collection subclass to have? Stephan

New CogVMs available
by Eliot Miranda July 24, 2014

July 24, 2014

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3056/. CogVM binaries as per VMMaker.oscog-eem.832/r3056 Add the time zone to the version info on Mac OS X and Win32. Fix bug in assigning parameter 55 (growth ratio at which to do a global GC). Add vmParameter 52 to answer the capacity of the root table (in Spur a.k.a. the rememberedSet). In the wake of the inlining change below (see Slang:), split lookupInMethodCacheSel:classTag: into inlineLookupInMethodCacheSel:classTag:, and use the inline version in internalFindNewMethod. Fix printStringOf: (used in e.g. frame print) to not print crs that would cause previous info to be overwritten. Spur: Fix bug with class table management and two-way become. Because two-way become may do an in-place swap obj1 & obj2 in SpurMemoryManager>>doBecome:and:copyHash: may not be forwarded after the inner become. Hence they should not be followed if not forwarded. The bug manifested as Object's identityHash changing: superclass is the first slot in a class. Following an unforwarded subclass of object yields Object. Setting the hash bits of the followed object smashes Object's identityHash. Thanks to Stephane Rollandin for finding the bug. More rationalization of the class table management post become. Now no post become scan of the class table is necessary at all. Add vm parameter 53 to answer the number of segments. Move the rememberedSet into a pinned object in oldSpace. Allow it to grow on demand, starting at 1k entries, doubling on each grow. Make sure to abort if the attempt to grow the remembered set fails. Try to grow by another 1k slots if doubling fails, then abort. Revise markAndTrace: given that markAndShouldScan: is inlined within it (see Slang changes below). Move the ephemeron processing into markAndShouldScan: out of the now unused numStringSlotsOf:ephemeronInactiveIf: circumlocution. Add activeAndDeferredScan: and numStrongSlotsOfInephemeral: in place of the double negative inactiveOrFailedToDeferScan: and hence inline numStrongSlotsOfInephemeral:. Increase the traceImmediatelySlotLimit. These changes plus the 2 repeats for compaction speed up global GC by at least x2. Change the defaultEdenBytes to 4Mb. Allow the number of compaction passes to vary, 2 on GC, 3 on GC for snapshot. Slang: Add support for inlining into the condition of ifTrue:/ifFalse: when it is marked as inline. Transform expr1 ifTrue:/ifFalse: [^expr2] by inlining ^expr2 into expr1. Transform expr ifTrue:/ifFalse: [statements] by replacing ^boolean occurrences in expr with gotos. -- Aloha, Eliot

The first thing to do is to walk smalltalkhub, squeak source and ss3 packages to check which ones have those extensions. I assume a MooseMonticelloHTTPImporter can be used for that Stephan
