Changes Unknown when pulling 9efd53c on tian2992:master into ** on DenisCarriere:master**.

@tian2992 Thanks for the PR, however what's a snap package? and how would this be used? Can you elaborate more on the purpose of snap packages (I must be out of the loop on this topic).

Hello @DenisCarriere! Snapcraft is a new packaging format for all Linux distros, that we are developing in Ubuntu. You can read more here: https://snapcraft.io/

Once the snapcraft.yaml is in your master branch, you can just go to https://build.snapcraft.io to automate the continuous delivery of updates to the Ubuntu store.

\o/ thanks for the merge @DenisCarriere.

@tian2992 did this as part of a workshop during a Central American free software conference. Nice work, thanks to you too!

The geocoder name is now registered in the store under @tian2992, which was an exercise we did to learn about publishing. But if you want to start publishing geocoder under your official name, I can make the transfer. @DenisCarriere you just need to fill this form, explaining that you are the original author: https://dashboard.snapcraft.io/dev/snaps/register-name/

pura vida

👍 Yes if we could transfer the repo that would be great.

[come-maiz]

Just let me know when you are done with the form, and I can click the button.

[DenisCarriere]

Ok, ready whenever you are.

[DenisCarriere]

[come-maiz]

Done. Please let us know if you have any issues with build.snapcraft.io.
And once you have the snap in the edge channel, we can make a call for testing with the Ubuntu community to get more people trying it before making the first stable release.

[DenisCarriere]

[DenisCarriere]

So these snap packages are mostly for CLI based applications, correct?

[DenisCarriere]

Looks like it's built and released, anything else more to do on my side?

[come-maiz]

No, there are also GUI snaps. For example, try:

sudo snap install keepassxc

But it is not for libraries. After installing the geocoder snap, only the CLI script can be executed, it can't be imported from a python terminal. It's like we have virtualenv for development, and snaps for deployment.

For your side right now, it only remains to suggest to your early adopters and contributors to give it a try with:

sudo snap install geocoder --edge

Then, when you are happy with the quality of a version and want to make it visible on user searches, you just run:

snapcraft release geocoder <revision> stable

[DenisCarriere]

Doesn't seem to recognize the geocode CLI...?

Does it work for you?

$ snap install geocoder --edge --devmode 
geocoder (edge) 1.23.2 from 'deniscarriere' installed
$ geocode
zsh: command not found: geocode

[come-maiz]

The name of the command chosen by Sebastián is geocoder.

The name of the command is a combination of rules between the name and apps fields in the snapcraft.yaml. If you want the command to be geocode, you would have to rename the snap to geocode, or use an alias.

[DenisCarriere]

Perfect, thanks, it somewhat works now:

Going to switch it back to Python2 and 🤞 it should work.

This is pretty slick! I'll continue to maintain these builds for future releases and other projects.

RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment.  Consult http://click.pocoo.org/python3/for mitigation steps.

This system supports the C.UTF-8 locale which is recommended.
You might be able to resolve your issue by exporting the
following environment variables:

    export LC_ALL=C.UTF-8
    export LANG=C.UTF-8

Click discovered that you exported a UTF-8 locale
but the locale system could not pick up from it because
it does not exist.  The exported locale is "en_US.UTF-8" but it
is not supported

[come-maiz]

@DenisCarriere you can make sure that the right encoding is before executing the command binary.

Something like this:

command: env LC_ALL=C.UTF-8 LANG=C.UTF-8 bin/geocode
