Visualise macports dependencies

to clean up your installed macports and remove cruft you need to uninstall them in the correct order – according to their dependencies. A graphical visualisation might help doing so: Call $ ./port-deps2dot.rb | dot -Tpdf -o port-deps.pdf ; open port-deps.pdf with the ruby script port-deps2dot.rb as follows: #!/usr/bin/ruby -w   # visualize macports dependencies.

TextWrangler + tidy

as I didn’t get TidyService to work correctly with UTF8 umlauts, I created a UNIX Shell Script wrapper for html tidy as it comes with OS X that does the job at least for TextWrangler: open TextWranglers “Unix Filters Folder” create a file named e.g. “Tidy Html.sh”, paste the following lines into the file and [...]

You should either select a different format (DOT_IMAGE_FORMAT in the config file) or install a more recent version of graphviz (1.7+) ? Happened to me this morning when running doxygen [...]

Plus the CFArrayBSearchValues doesn’t tell you whether the key actually is part of the list or not. That’s what the Java JDK does, so let’s implement some category methods -(NSInteger)binarySearch:(id)key; -(NSInteger)binarySearch:(id)key usingSelector:(SEL)comparator; [...]

NSDateFormatter case sensitive trap

Though NSDateFormatter behaves slightly different than documented, the following might even be correct, as strange as it might look (mind the last two lines): -(void)testNSDateFormatterTrap { NSDateFormatter *lower = [[[NSDateFormatter alloc] init] autorelease]; lower.dateFormat = @"yyyy-MM-dd HH:mm:SS ZZZ";   NSDateFormatter *upper = [[[NSDateFormatter alloc] init] autorelease]; upper.dateFormat = @"YYYY-MM-dd HH:mm:SS ZZZ";   lower.timeZone = upper.timeZone [...]

HFS Filesystem Party

Vorgestern Nacht hat – möglicherweise im Zusammenhang mit einem unaufmerksam durchgeführten Java Update – das Filesystem meines Macbooks einen Schuß bekommen.
