We use a “.DS_Store” file to apply our background, size, and icons to the macOS installer. Generating or modifying this .DS_Store file is difficult and involves many manual steps (described in ctc/client/macos/ThinLinc/README). This could be easier and done without going back and forth to a macOS machine. There is a Perl module called “Mac-Finder-DSStore” that, can both parse and write new .DS_Store files: https://metacpan.org/release/WIML/Mac-Finder-DSStore-1.00 Modifications to the macOS installer would then easily be done in the DS_Store.pl file, which is humanly readable. Using the Mac-Finder-DSStore module we could have a checked in “DS_Store.pl” which, which when executed, with “perl DS_Store.pl”, would generate a new working .DS_Store file.
Created attachment 1057 [details] Patch required for building Mac-Finder-DSStore This patch is required in order for building Mac-Finder-DSStore on Linux. It includes two fixes: * The recommended requirements "Mac::Files" and "Mac::Memory" are removed from Build.PL. Despite them being optional it didn't build without them. Both these perl modules only seem available on macOS machines. * Added types for the properties "pBBk" and "pBB0". These types appear in modern .DS_Store files but seems like they didn't exist when the module was written. Without this patch we can't build new .DS_Store files from perl input that contains this property.
Created attachment 1058 [details] Patch required for Mac-PropertyList The perl module Mac-PropertyList is required by Mac-Finder-DSStore for parsing and printing .DS_Store plist data. The code that this patch fixes seemed broken, it asserts that the variable $power2 isn't bigger than 3, but just a few rows down has code that handles the case when $power2 == 4. After this change it was possible to parse both old and modern .DS_Store files.
Created attachment 1059 [details] Perl script that generates a working .DS_Store file This perl script was generated using Mac-Finder-DSStore (patched) with an old .DS_Store file as input (Note that the --raw-aliases flag is required since we won't have the "Mac::Files" and "Mac::Memory" requirements): perl Mac-Finder-DSStore-1.00-patched/examples/dsstore_dump.pl --raw-aliases ~/DS_Store_old > ~/DS_Store.pl This perl script can then create a working .DS_Store file: perl ~/DS_Store.pl
Note that the generated perl scripts sometimes generate warnings. One example that we manually adjusted was this: > ... > "showItemInfo" => bless( do{\(my $o = "false")}, 'Mac::PropertyList::false' ), > "textSize" => bless( do{\(my $o = 12)}, 'Mac::PropertyList::real' ), > "backgroundType" => bless( do{\(my $o = 2)}, 'Mac::PropertyList::integer' ), > "arrangeBy" => bless( do{\(my $o = "none")}, 'Mac::PropertyList::string' ), > "labelOnBottom" => bless( do{\(my $o = "true")}, 'Mac::PropertyList::true' ), > "backgroundColorGreen" => bless( do{\(my $o = 1)}, 'Mac::PropertyList::real' ), > "viewOptionsVersion" => bless( do{\(my $o = 1)}, 'Mac::PropertyList::integer' ), > "gridSpacing" => bless( do{\(my $o = 100)}, 'Mac::PropertyList::real' ), > "gridOffsetX" => bless( do{\(my $o = 0)}, 'Mac::PropertyList::real' ), > "showIconPreview" => $VAR1->{"showItemInfo"}, > "iconSize" => bless( do{\(my $o = 128)}, 'Mac::PropertyList::real' ), > ... The "showIconPreview" property line gave the following warning when we tried to create a new DS_Store file: > Name "main::VAR1" used only once: possible typo at /home/cendio/DS_Store.pl line 29. It is likely a harmless warning, but we fixed it by replacing the $VAR1 reference with its value found up with the "showItemInfo" property, like this: > "showIconPreview" => bless( do{\(my $o = "false")}, 'Mac::PropertyList::false' ),
