In the last few days I have begun to understand pyinstaller.
Depending on the generate_folder switch, launchLeo.spec now generates
either:
1. a single file, Leo.exe, containing /everything/ needed for Leo, or,
2. a folder containing Leo.exe and everything else needed.
The advantage of 1 is that the user can just double-click on it to
start running Leo. The advantage 2 is that the user can see and open
.leo and .py files that are part of Leo. In the next day or so I'll
be making both versions available for newbies. Either way, the user
need install /nothing/ to run Leo!
Imo, both PyInstaller itself and its documentation are superb.
However, I really didn't understand what was going on until I started
using PyInstaller. The key Aha was that, /even in case 2/, so-called
pure python modules do /not /appear in a leo folder. Instead they are
put somewhere else, probably in Leo.exe itself. Indeed, to get any
leo folder at all, files must be added to the so-called "datas" list.
At present, the same datas list is used in both case 1 and case 2, but
there is no point in adding most of those elements for case 1 because
there appears to be no way to open those files.
This is going to be a big deal for Leo. For the first time ever,
people will be able to try Leo without installing anything. This what
Kent has been wanting forever, and I now see much more clearly why.
Thanks a lot! I was also asking for it long time ago (I was the teacher
that back in ~2005 reported some issues with installing and version
while trying to teach with Leo to their students). I don't use/teach leo
these days, but some of its ideas has been a source of inspiration and
having an easy to install self contained package for windows will help
to inspire others with Leo.
Cheers,
Offray
