nsisPatchGen - Automated patch generation

viperpiper · 24th May 2006, 21:20

Hi,

We have made a utility available that automates the procedure for creating an installer that patches multiple files.

The "NsisPatchGen" utility recursively compares two directory structures looking for changes to the files and subdirectories. It produces an NSIS include file containing functions that will perform a patch upgrade from the original structure to the new.

nsisPatchGen uses the VPatch genpat.exe utility to generate patch files, and calls VPatch plugin function calls from the generated NSIS file.

nsisPatchGen can be downloaded from:

http://sourceforge.net/projects/nsispatchgen

Hope some of you find it useful

Cheers,

Bruce

Very nice

Would be nice if you could put up a Wiki page for it.

Yep - I've added a little to the end of the VPatch page. I'm away for a week but I'll do a full page when I get back.

I really like your program.

I'm new to the GPL though.
I'm working on a closed-source program. Would it be ok if I included your exe with my program (I'd give credit and include/link to the source code of your program, just not to the source code of my program)?
My program doesn't use any source code from your program, it just executes it.

I'm pretty sure this would be ok under the Lesser GPL (since that one specifies that even library LGPL code can be used by a closed-source program, so an EXE would be even less of an issue).

Under GPL that is probably a deriative work, so it's not allowed unless you get permission from all contributors.

Hi Code626,

I'm new to the GPL myself - though it was my understanding that using the exe would have been OK.

I certainly don't mind the program being used in the manner you describe. As the only contributers so far are the original authors then you have our permission.

Any GPL experts out there that can give a definitive answer on this?

When I run this over two versions of our software I only get the name of one of our sub-folders inside the patchfiles folder. No script, no pat files?

I have added VPATCH with the path where genpat.exe is located to the enviroment variables and added %VPATCH% to the path. I am currently running Windows Vista.

If on Vista, try running it from Administrator's CMD.
