rsrce - editor for raw MacOS resource forks


rsrce [filename]


Rsrce is command driven Macintosh resource fork editor for Unix-like operating systems.

Rsrce doesn't allow you to edit the resource data directly. It only knows to import/export them from/to files, performing conversion for the few resource types it knows.


If a filename is given on the command-line, the resource are read from the file when rsrce is launched.

Resources are referred to by specifing their type and id, separated by a colon. I mean, something like "STR#:128". If the type field contains less than 4 letters, spaces are added to complete it.

The following commands are available:

read file
read the resources from file
write file
write the resources to file
list resources (type, id, attributes, data lenght, name)
hexdump resource
show an hexdump of resource's data
import|export resource file
import/export resource's data from/to file
edit resource
invoke an external editor to change resource's data
list available commands
terminate rsrce (without saving, use write before exit if you wish to save your changes)


Rsrce has only been originally created to change the configuration of the miBoot Linux bootloader for OldWorld PowerMac computers. Since I do not use MacOS, I haven't tested any other usage of this program. You should therefore be very careful when using it, as it could very well produce unusable output.

Another consequence of this is wildly missing functionnality. I'm not going to work on it, since I couldn't test anything in a real situation. Patches and/or usage reports would be very welcome.
