While I've done this sort of installer myself (using
'compress' to store each file in a custom property and
then 'decompress' later on while reconstructing the
directory structure) it has a few caveats:
- on Mac and Linux, you'll have to do some shell calls
to mark your actual executable file as executable
(that's where 'chmod' comes in)
- on Mac you will have to save the 'fileType' of each
file and set it as you write your decompressed files
(the easiest way is to setup a separate 'metadata'
custom property set)
- on Mac you may also want to read/write the
'resource fork' of files (easy enough to get/put with
'URL "resfile:" & tFilePath')
- the file creation/modification dates on the user's
computer won't match yours (which means you can't rely
on them for versioning)
But you could perhaps work around those limitations
using the 'revZip' set of external commands and
functions - I haven't actually tested if
'revZipAddItemWithFile' and 'revZipExtractItemToFile'
cover all these situations.
As a bonus, you can easily poke the Windows registry
using built-in Revolution functions without having to
learn some obscure installer scripting language.
