Hi, when creating a file, the line end convention of the OS is not enforced by default. As an example, FileStream forceNewFileNamed: 'test' do: [:stream | stream nextPut: $a; cr; nextPut: $b; cr] always creates a file with MacOS X line end convention. To enforce the line end convention of the system, one has to do the following: ... do: [:stream | stream wantsLineEndConvention: true; ... is it the desired behavior? If yes, should we ensure that #wantsLineEndConvention is called each time Pharo generates a file for the user (e.g., PharoDebug.log). -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."
