Those are likely to be your original Python 2 files, before the script made
changes, allowing you to roll back. They should definitely not be published,
but you should keep them yourself until you are confident the conversion was
successful.

I'm wondering if you could solve this by doing something like:

1. apply a filter to your atlas so you only iterate over half the features
2. don't use the built-in "controlled by atlas" setting for maps, but
instead retrieve the second page feature directly using the
get_feature function, and then use data defined x min/x max/ etc and
to set the scale/extents of the second page map.
3. similarly, use get_feature to retrieve attributes for the second
page feature for the surrounding text content.

> 2) How much work would it be to enable support for this kind of work flow?

Not as far as I know. I'd personally consider it a bit of an edge
case, so not something which belongs in master. But in 3.x plugins can
tie strongly into the whole layouts engine and interface, so
potentially there's scope for a python plugin to handle this.

The 3.0 reports functionality should already be able to do that now.

Digitizing tools is a 3rd party plugin - you need to report all issues
to the plugin author, not the QGIS project:

Yeah I though of similar things too though I was looking more for something we 
could give to end users (i.e. something clever we could add to core to support 
producing print ready books).

So maybe a plugin using pdfimpose (thanks for sharing that library, I havent 
seen it before!) might do it. I will go and check it out next weekend.

For ‘doing it in core’ I was wondering if we couldn’t have a concept of a frame 
item which is a virtual page that you can add to a layout letting you basically 
have two (or more) frames on a page side by side, with the atlas incrementing 
the currentAtlasFeature as it visits each frame.

Re: [QGIS-Developer] Running qgis2to3 on windows

[DelazJ]

Hi Tom,

Not really. It expects qgis2to3 to be a file in such a command. But it
makes me remind to look for a qgis2to3 file and i found it in
C:\OSGeo4W64\apps\Python36\Scripts. Moving to that folder and calling
`qgis2to3 -w /path/to/my/plugin` did the trick.

Thanks for your help.

Next question: I realize that other than changing my existing files it also
creates some .py.bak files. Anyone knows what I am supposed to do with
them? Should they also be in the published version (they seem to be
generated automatically)?

[QGIS-Developer] Running qgis2to3 on windows

[DelazJ]

Hi,
I'm trying to update a plugin of mine to QGIS3 and follow instructions at
https://github.com/qgis/QGIS/wiki/Plugin-migration-to-QGIS-3
I'm on Windows 10 and am not used to dev env and despite the use of osgeo4w
i encountered some issues.
After some readings here and there, I ran in the osgeo4w shell the
`py3_env` call to update my environment, leading to
PATH contains C:\OSGeo4W64\apps\Python36
PYTHONHOME = C:\OSGeo4W64\apps\Python36
PYTHONPATH = C:\OSGeo4W64\apps\Python36\Lib

Following the wiki, I ran `pip install future` or `pip3 install future`
(I'll realize later that future was already installed) but any call of
pip/pip3 like a simple `pip --help` results in *Fatal error in launcher:
Unable to create process using '"'*
After some search, I found that the call i should do is `python3 -m pip
install future` [1]. Did I miss something or would the guidelines need some
contextualization for beginners like me?

Then running `python3 -m pip install qgis2to3` downloads and installs the
qgis2to3 package in the osgeo4w. But when i run `qgis2to3
/path/to/my/plugin` I simply get a dialog to select the app I'd like to use
to open the file (which happens to be
C:\OSGeo4W64\apps\Python36\lib\site-packages\qgis2to3\__init__.py). No
more. I don't know what to do ...
Sorry if these are noob concerns but I can't move forward so any help would
be more than welcome.

Thanks,
Harrissou

Re: [QGIS-Developer] Using Atlas in QGIS 3 to make a print ready publication

[Alexandre Neto]

Hi Tim,

To do what you want, the only way I can imagine is creating a Layer with
two geometry columns for coverage. The first column would be a "normal"
geometry column and could be used by atlas to provide the left page
iteration. The second column could be stored in WKT, and using the data
defined overwrite on the extent options to provide the right page iteration.

The problem is that the coverage layer would need to be carefully
(manually) crafted to create the odd and even pages. It would need to
titeBesides, for the right page you would not be able to use atlas
variables.

I wonder if it wouldn't be easier to create all the individual pages
normally using reports (to add static pages), export to PDF, and then
create a booklet from it. I bet there are tools for that.

For what I could gather, this kind of work is called creating a booklet, or
page imposition. There is a python library to work with that:

https://pypi.org/project/PdfImpose/

Best regards,

Alex Neto
