Hi Don,
Im glad you had some luck with it finally.
The report does not include any files line numbers because it does
a binary compare, not a 'text' or 'line by line' compare. I had
it do a binary compare because many of the files are not text files
(or euphoria source files) but are instead .exe files, .dll files,
etc., with some text files too.
I guess what you would want to see is the compare action taken
commensurate with the type of file? I guess that's not a bad idea
really. We'd have to also supply a list of file extensions and
how those files should be handled, but i guess that's not too much
work to do. On the other hand, the program would then also have to
work with different formats, like .doc and .rtf and be able to
handle unicode. Im not sure if i want to get into that myself
even though it could be done.
Maybe you want to be able to compare Euphoria source files too?
For now though it looks like it will compare in binary mode only,
however it would not take much to get it to report exactly which
byte was different, and then you could go back and open the files
and provide a dump of part of the two files. Even so, only the
first difference found would be reported as (at least currently)
the algo exits at the first difference found just after writing
to the report file.
Another thing i should mention (and this is written in the file
itself in a comment section) is that for two directories, call
them A and B (and the variable names reflect this convention with
their last letter being A and B respectively), the file names
(and directory names) not found in B are reported (B is the backup)
but the file names and dir names in B (if there are any) that are
not in A are *not* reported. This is because if for some reason
you feel like including an extra file in the backup for some reason
and you dont really need it on the hard drive, you dont have to
skip reading it in the report file. If this is a problem however,
it doesnt take much to have the 'missing' A files (and dir names)
reported in the report too.
BackupList.txt:
The other convention used is that file names end with no backslash,
while directory names *always* end with a backslash. This is so
another program can go through the list in the BackupList.txt file
and detect when it has to write an entire directory to disk rather
than a single file. Writing an entire directory means writing
the root files and every sub directory and all those files too,
whereas writing a single missing file is a simple 'copy file'.
Take care,
Al
E boa sorte com sua programacao Euphoria!
