GetMax - BlitzMax Downloader

GetMax does what its name says: Gets the latest (SVN) version of BlitzMax for you.

Upsides: has a simple GUI, does NOT require an SVN client and is small.

Downsides: rather slow, does not update and has no error handling.

Source available below.



Updated with SebHoll's changes.

No offense, but based on the latest issue with EXEs, you might want to release the source now, as I doubt many will touch an EXE right now.

I get your point. EDIT: Source released. Messy but works.

Should be a useful utility for folks ;)

Sounds great.

Would be awesome if such a downloader would be included in the IDE.

Thanks a ton!

Except of course you'll need to have MinGW installed to use the source.
And it's a lot to download each time you want to check if something has been updated.

But otherwise, it does usefully fill a gap :-)

Nice work!

I've tweaked the UI slightly and swapped the byte-by-byte stream code for the much the faster ReadBytes()/WriteBytes() alternatives:

Otus, feel free to update your original post if you approve.

Thanks, I updated with your changes and a couple of other issues.

Nice work. Makes life a little easier than using SVN all we need now for it to do is update only the new or changed files. I will test this on the Mac and Ubuntu.

Edit: Ubuntu's ok. But for some reason it will only work on a Mac within the IDE in debug any ideas? (I'm not a big Mac OS X user)
