When following the tutorials, I am able to complete tutorial 1, but tutorial 2 will not run on a physical iOS device - only on the simulator.

When I attempt to run it on an actual iOS device, the app will display the splash screen but then quit straight after.

The error message from the console is:

I'm using Xcode 7.3.1.

Any advice?

Are there plans for BeeWare to support Windows Phone 10?

I just did a fresh install of sierra, and have installed pyenv with homebrew and tested that it's working. I have a local 3.5.0 version of python in a virtualenv (read that 3.6 isn't working). I go through the tutorial and everything works until i try to compile...

import zlib

fails because zlib.cpython-35-darwin.so is not included in Python-3.5-macOS-support.b2.tar.gz.

Any chance you guys can build python with the cpython .so stuff included so that hashlib picks up the 'ripemd160' hashing algorithm?

I need this algorithm to be available from the Python provided by HashLib.. but it isn't.

I'm porting Electron Cash to iOS.. which is why I ask.

Otherwise great work guys!

Right now, updating the code in an app doesn't update the code in the generated template. There's two parts to fixing this.

One is make running setup.py for Briefcase idempotent (related to #25).

Two is adding some sort of "watcher" that will update only the parts needed when the app changes.

Hi guys,

I'm porting Electron Cash (the bitcoin cash SPV wallet) to iOS and I'm using your wonderful Briefcase project to do it.

Electron Cash depends on libOpenSSL, which thankfully you guys compiled for Simulator & device and have included (yay!).

It also needs the python 'cryptography' module, but this module includes native C-parts compiled as .so's.

I can't figure out how to get this module into an iOS simulator & device. Ideally I would just compile it into fat binary .so's for iOS & Simulator and be done with it -- but the setup.py business and pip are cryptic to me (I'm an iOS dev, not much of a python dev).

Can you guys help me? How do I get started? In general how do I compile python modules that contain native bits to work on iOS & Simulator?

ANY HELP IS APPRECIATED! Thanks in advance!

EDIT: It turns out I need 'ripemd160' from hashlib and OpenSSL. Will open another ticket for this.

I installed briefcase using pip install briefcase, but then I couldn't run briefcase as I get:

(ENV)$ briefcase
-bash: briefcase: command not found

Now when I try and build the toga webkit browser test app I get the following error:

(ENV) $ python setup.py osx
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'osx'

This is probably because the briefcase commands have not been added to my virtual environment? OS X 10.11.4; Python 3.5.1

Briefcase installs the platform requirements defined in the setup.py file.

For someone using briefcase-template, for example, this means that it will pip install into the $PLATFORM/app_packages directory the packages defined in the setup.py.

It would be nice to have a "platform developer mode", which would use a local version of those packages (specially useful for someone working on Toga).

One idea to implement this would be to provide a way of configuring alternative local versions for the requirements there, e.g.:

python setup.py TARGET --overrides package-overrides.json

And then, package-overrides.json could have something like:

{
    "toga": "/home/elias/src/toga/src/core/",
    "toga-android": "/home/elias/src/toga/src/android/"
}

This information would then be used by the install_platform_requirements function to feed pip the package names with the overrides applied.

I'm a really newbie at this, so excuse me if I write something stupid :p

Moving on, the only error that appears is this:

Complete output from command python setup.py egg_info:
running egg_info
error: Invalid distribution name or version syntax: toga--0.1

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-klmvtchk-build/

I looked in briefcase files, trying to figure it out where he requires the toga--0.1 but can't find it, to help fixing this.

In the end it claims Installation complete ready to build the apk.
So, I ran the ant debug , 15 seconds later expels the *.apk with 135kb

I installed it on Android, no Bugs, except when I open it.
I says every time Hello World on a black screen, even if I don't used those words in any way (name, vars, config) so must be a default file that compiles...

Where to start to fixing this ?

Some suggestions:
I setup a new instance of Linux in VirtualBox for this, so I start fresh
The pip install toga was ok, but on pip install briefcase crashed with the Exception git not installed ,
and I easily installed git.
But the author intends that this tools should be used by children/newbies in this PyCon presentation, so I think we should create a file(for eack pybee package) like os_requirements.py or os_setup.py or even os_must_have_this_to_run_this_tool.json, and check if the OS requirements are installed (as soon we figure it out what we need in individual platform), for each platform (maybe it seems excessive, but is nice for those that are giving the first steps, and they don't go away to use another tool instead)

for this git thing we can proceed with:

has_git = subprocess.check_output(['git', '--version'])
except FileNotFoundError:
if os.uname()[0] == 'Linux' and 'Ubuntu' in os.uname()[3]:
print ('you need to install git with "sudo apt-get install git"') right ?

or maybe if the git is just to download the file and install it with pip, by simply change to pip install --upgrade git+https://release (it will always download the latest)

but I'm not sure if works with this command,
https://github.com/pybee/briefcase/blob/master/briefcase/app.py#L99
because I don't understand if is looking for toga or something like toga-android but for main packages works...

We could do this for git, JAVA_HOME, javac and so on, because even for me it's not easy to configure OS_dependencies.

Waiting for instructions, maybe I can help with this, with tousands of bugs :p

I've tried to follow Tutorial 0 with the following commands:

Getting Started (but with a conda environment):

conda create -n toga python=3.4
source activate toga
pip install briefcase 

Tutorial:

pip install cookiecutter briefcase
cookiecutter https://github.com/pybee/briefcase-template
cd tutorial_0

Note, here I do not ""Add this"" to tutorial_0/app.py but rather replace. I think if it is just added, there would be two main() functions, which might be a problem.

Then, when try to run it with python setup.py ios, I get the following error:

At the time of writing this issue, nothing is on Google (or Bing!) when I search for those error messages, so I thought people here might be able to help debug this.

Currently, briefcase looks for app.py which starts the application. It would be nice if an entry point could be specified instead. See pynsist's entry_point for inspiration.

The tutorial doesn't give any indication that I need to so anything special to get Xcode commands working; it goes straight from writing my Python code, to running the above Distutils command.

Currently, we only use the template and support package for the user's running Python version.
It would be nice to allow users to override this, making it easier for people using the most recent Python versions (and maybe even the release candidates) to try things out.

It would be great to be able to do python setup.py ios --use-python-version=3.6 =)

Now that the Python iOS support libraries support tvOS, Briefcase should also support that platform.

This will involve adding a new command to Briefcase to support tvOS. The implementation of this command will be almost identical to iOS, with names and images changed.

A template cookiecutter project already exists.

@freakboy3742 I noticed that you are exploring ways to fund pybee (beeware) development. So why not open a marketplace? This is where developers can easily deploy their apps on multiple devices and consumers can easily get them on their platform. This can of course be integrated with existing app stores by providing a "runtime" which all apps can be built on top (e.g. like adobe air).

How should Linux support work?

One way would be to have some sort of build system that always carefully only links against libc 5, does everything statically, etc, and builds everything into a big binary.

Another would be to instead have multiple backends for .rpm, .deb, etc. I imagine that this would be different from bdist_rpm, bdist_deb et. al. by doing some automatic determination of what the package dependencies ought to be by looking for shared library dependencies. Despite the fact that this would not be nearly as self-contained, it might be more practically useful to begin with.

It would be really awesome if briefcase could build a minified, combined JS bundle for deploying into a browser, as well.

Thanks so much to the developers of this project, I am absolutely loving working with this, just had a little hiccup. 😳

Is there another cookiecutter template I need to install from somewhere?

There is no way of knowing that Briefcase won't install correctly on GNU/Linux from the installation instructions. It should be clear that they are for Mac OS.

When running the simple helloworld tutorial on OSX, i get the error when running the command

python setup.py ios -s

The app gets installed on the virtual iphone but the app just crashes when opened, does not display the "hello world text"

Also get the following error at the same time:

Abstract

Develop a Visual Studio 2017 solution file that will enable a user to download a zip file of content (including a solution file), open the solution, hit run, and have the code Just Work (tm).

Full description

Python.net contains an example project that shows how to embed a Python interpreter into a C# project. However, this project doesn't work "out of the box" - it requires a bunch of configuration before it will work. It is part of a larger project, so you need to modify the solution file to set the starting project; then, when you do run it, you get errors because Python27.dll can't be found - which is problematic if you're trying to use Python 3.5.

I want to be able to give someone a zip file that contains the solution file and source code, have them open the file, run it, and get a useful executable.

The deliverable is the zip file, containing a Visual Studio 2017 solution file, the C# source code from the Python.net console demo, and any other support files necessary. I imagine this will include:

A copy of Python. The zip file should contain the official embedded python zip file in a known location relative to the solution file. However, you cannot depend on a system installation of Python (or anything else other than Visual Studio).
An installation of Python.net. Ideally, this will be in a directory other than the site-packages provided by the embedded Python install
When compiled, the executable should have a custom icon; any icon will do for sample purposes, but it should also be available in the zip file.

The ideal layout for the final zip file would be:

• Windows
  • MyProject.sln
  • MyProject.cs
  • MyProject
    • Resources
      • myproject.ico
    • Python
      • (contents of embedded Python zip file)
    • app_packages
      • (installed version of python.net)
    • app
      • MyProject
        • __init__.py
        • app.py

The solution file should output "MyProject.exe" in the MyProject directory.

Bonus points

For bonus points:

1. The default source from the console demo of Python.net will require a command line argument; modify the sample code to invoke app.py with the contents of app and app_packages in the PYTHONPATH for the purposes of execution.

2. The output app should be a gui app, not a console app. When MyProject.exe is executed, a black console window should not be displayed.

3. Add a target to the solution file that produces an MSI installer with contents of the "MyProject" directory, including the executable, embedded python, app_packages and app.

When briefcase runs cookiecutter it tells it to check out the branch that corresponds to the Python major.minor version being used.

However, cookiecutter does not do that when given the directory path to the git repo, so briefcase should checkout the right branch when deciding to reuse the local template.

I think it makes sense to do git checkout BRANCH_NAME inside of the git_pull() method, just before doing the pull.

Hello!

I am working on getting the widgets that haven't been implemented on Gtk, yet have been implemented on the Cocoa backend.

Toga-gtk
https://github.com/pybee-attic/toga-gtk/tree/master/toga_gtk/widgets

Toga-Cocoa
https://github.com/pybee-attic/toga-cocoa/tree/master/toga_cocoa/widgets

**My question is, the script icon.py is found in both of the backends, yet the script image.py is not included in the toga-gtk backend. Is there a reason for this? Are we using the icon as an image also?

If not, may I create this file and widget also? (maybe change the name if it is for all image uses)
OR
Are we using the "icons" as images also?**

-Thanks for teaching me & thank you for your time!

Instructions for debian jessie are missing in the getting started document.

Currently, briefcase always re-downloads the cookiecutter template.

Since re-generating an application bundle (for example, running python setup.py ios or python setup.py android) is meant to be a very common thing to do, it would be nice if it tolerate network issues.

My suggestion is that we check if there is a template already downloaded, and if it does, instead of re-cloning it, we'd try updating it (running git pull) and just emit a warning in case updating fails.

If you have an existing macOS directory, and you run python setup.py macos, you get a messy error message about a directory already existing. The same is true for other platform directories.

It would be better to replace this with a check - "do you want to replace this project y/n", and if y, delete the existing directory before regenerating.

Under Tutorial 1, Use the same code...
https://briefcase.readthedocs.io/en/latest/tutorials/tutorial-1.html#use-the-same-code-but-for-the-web

Probably a missing/misplaced newline, RST is fun

It may be useful to execute the migrations for the user once the setup has been successful. There might be some inconveniences so I will like to discuss the pros and cons of this option.

When using briefcase to create an xcode project from python code which uses audiostream - the build goes through fine but when the xcode project is run the following error is encountered

("No module named 'audiostream.core'",)

This occurs at the line

        from audiostream import get_input

Suspected reason: The audiostream directory has core.c, core.pyx which would need CythonRecipe as indicated at the kivy-ios page

Note: as audiostream is not recognized by default when added to app_requires in setup.py despite being installable via pip (not sure why), I worked around it by

• downloading the audiostream project
• modifying the setup.py script since it had print statements in python 2.7 format instead of python 3.4
• creating a zip file
• adding the complete path to this zip file to the app_requires section

Other details

• python 3.4,
• compiling for iOS
• the setup.py and app to reproduce the issue are as attached.

Hej,

I am experimenting with Briefcase. I cannot get the Tutorial 0 (https://briefcase.readthedocs.io/en/latest/tutorials/tutorial-0.html#) to work on my machine. Likely it is something obvious, but I do not know what to look for.

After following the steps of the tutorial, XCode prints the following error into the console instead of the Hello, World! message:

2017-04-22 01:17:57.647 Hello World[74577:3342107] PythonHome is: /Users/thisisme/Library/Developer/CoreSimulator/Devices/BD73FC4D-D82B-4296-A6F6-B8A75806BFC4/data/Containers/Bundle/Application/9BBFB0DA-AF7E-4CB8-B48B-E382F34B7616/Hello World.app/Library/Python.framework/Resources

2017-04-22 01:17:57.787 Hello World[74577:3342107] Unable to locate HelloWorld main module file

I am OS X 10.11.6, XCode Version 8.2.1., virtualenvwrapper to manage my virtualenvs, and I am in an virtualenv with a Python in version 3.5.2.

I followed the steps tutorial:

mkdir tutorial
cd tutorial/
mkdir iostutorial
cd iostutorial/
mkdir HelloWorld
touch HelloWorld/__init__.py
echo 'print("Hello, World!")' > HelloWorld/app.py
touch setup.py
nano setup.py

Into the setup.py, I copied the code snippet given in the tutorial.
After the steps above, my project looks as in the following:

 └── tutorial
     └── iostutorial
         ├── HelloWorld
         │   ├── __init__.py
         │   └── app.py
         └── setup.py

Subsequently, I build the project, open it with XCode, and run it there (via the play button)

python setup.py ios
open iOS/Hello\ World.xcodeproj/

After the Simulator started up I get the error message from the top.

What am I doing wrong? What do I have to fix?

When I try to:
import cryptography.fernet
I get:
ImportError: No module named '_cffi_backend'

This is apparently since cryptography builds with 'm' (see PEP 3149) and briefcase's python does not. Test case at: https://github.com/jamesabel/hello_briefcase . See https://github.com/jamesabel/hello_briefcase/blob/master/out.txt for details.

BTW I'm at the PyCon sprints today (5/25/17) so we can discuss this.

'nuff said

Not sure if this should be logged here or against toga, but when you specify, say:

'toga[iOS]>=0.2.0.dev1'

you get toga 0.2.0.dev1 but toga-ios 0.1.2.

After using briefcase to generate an iOS project from toga, I try to build in in XCode. I get the following errors:

ld: framework not found BZip2
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This appears to be a case sensitivity issue. In ./iOS/BZip2.framework, I see the following:

Headers -> Versions/Current/Headers
Versions
bzip2 -> Versions/Current/bzip2

But it should be BZip2. I can make the error go away with ln -s bzip2 BZip2.

The same error and fix are needed for XZ. Then the project compiles.

I'm trying to run briefcase (android target) using --support-pkg to provide a locally built support package, with the command:

python setup.py android --support-pkg ../voc-dev/voc/dist/Python-3.4-Android-support.b5.tar.gz 

I'm getting the following error:

 * Installing support package...
Support package: ../voc-dev/voc/dist/Python-3.4-Android-support.b5.tar.gz
error: Invalid URL '../voc-dev/voc/dist/Python-3.4-Android-support.b5.tar.gz': No schema supplied. Perhaps you meant http://../voc-dev/voc/dist/Python-3.4-Android-support.b5.tar.gz?

I tried providing absolute paths, but the result is the same.

At the moment you can easily create a macOS app with python setup.py macos and it works nice.
As a addition to that it would be super nice to have the ability to build to a macOS/cocoa/Xcode project with a command like python setup.py macos-xcode.

I know we can go directly from python to a executable app but I think there are benefits/possibilities for including macos/xcode as a possible packaging target.

Benefits:

• We could use the build in Xcode UITesing framework XCTest to perform unit as well as UITests.
• Uploading apps to the macOS app store?(not sure if there is a other way)?

Is briefcase able to package a flask web app?

With Briefcase 0.1.9 I was able to create a windows installer (MSI) for the temperature conversion app example, but after installing from the MSI, I needed to change the shortcut's Target field from
"C:\Program Files (x86)\Freedom\python\pythonw.exe" app\start.py
to
"C:\Program Files (x86)\Freedom\python\pythonw.exe" "C:\Program Files (x86)\Freedom\app\start.py"
for the program to run. (Windows 7 and Windows Server 2008)

Currently, we are testing changes in briefcase manually, it would be nice to have a testing suite.

Hi all,

I'm trying to build an executable for Windows using python 3.6.2, tkinter as GUI framework and with scientific packages such as numpy, scipy and pandas.

This is my setup.py generated by cookiecutter and then modified by me:

import io
import re
from setuptools import setup, find_packages
import sys

with io.open('./Blender/__init__.py', encoding='utf8') as version_file:
    version_match = re.search(r"^__version__ = ['\"]([^'\"]*)['\"]", version_file.read(), re.M)
    if version_match:
        version = version_match.group(1)
    else:
        raise RuntimeError("Unable to find version string.")


with io.open('README.rst', encoding='utf8') as readme:
    long_description = readme.read()

	
found_packages = find_packages(
	exclude=[
		'docs', 'tests',
		'windows', 'macOS', 'linux',
		'iOS', 'android',
		'django'
	])
	
print(found_packages)

found_packages.extend(['numpy', 'scipy', 'pandas'])

setup(
    name='Blender',
    version=version,
    description='An app that does lots of stuff',
    long_description=long_description,
    author='Jane Developer',
    author_email='[email protected]',
    license='GNU General Public License v3 or later (GPLv3+)',
    packages=found_packages,
    classifiers=[
        'Development Status :: 1 - Planning',
        'License :: OSI Approved :: GNU General Public License v3 or later (GPLv3+)',
    ],
    install_requires=[
    ],
    options={
        'app': {
            'formal_name': 'Blender',
            'bundle': 'com.example'
        },

        # Desktop/laptop deployments
        'windows': {
            'app_requires': [
            ]
        },
    }
)

But when I run python setup.py windows -s I get the following error:

...
Processing c:\users\test\documents\blender
    Complete output from command python setup.py egg_info:
    ['Blender']
    running egg_info
    creating pip-egg-info\Blender.egg-info

    warning: manifest_maker: standard file '-c' not found

    error: package directory 'numpy' does not exist

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\test\AppData\Local\Temp\pip-08c6dtgx-build\
...

I have a feeling that the build process does not have visibility of the site-packages path where the packages are installed. Is this due to the install location of python? How can I specify in the setup.py file where the packages live?

When running Tutorial 0 with target macos and Python 3.4 (i.e. python setup.py macos --support-pkg=/path/to/Python-3.4-macOS-support.b2.tar.gz), the app cannot be run, and gives the following error:

$ open macOS/Tutorial\ 0.app
LSOpenURLsWithRole() failed with error -10810 for the file /path/to/tutorial_0/macOS/Tutorial 0.app.

The problem seems to be that it is looking for python/bin/python when that binary does not exist, but python/bin/python3 does exist. There are two fixes:

1. Change the last line of macOS/Tutorial 0.app/Contents/MacOS/Tutorial 0 to python/bin/python3 -m tutorial_0, OR

2. ln -s python3 python in tutorial_0/macOS/Tutorial 0.app/Contents/Resources/python/bin

Could be something that I am doing.... I am not very good at this yet....
but when i am trying to build the android app it gives me this in the android studio "output".

Now that the Python iOS support libraries support watchOS, Briefcase should also support that platform.

This will involve:

• Producing a cookiecutter template project (analogous to Python-iOS-template)
• Adding a new command to Briefcase to support tvOS. The implementation of this command will be almost identical to iOS, with names and images changed.

Multiple apps in the one codebase are possible to define using setuptools entrypoints.
On Windows and Linux this produces multiple shortcuts / executables in the installed distribution.
On other platforms where apps are fully packaged (macOS, iOS, tvOS, Android) this is not possible.

It would be better to be able to produce multiple packaged apps for each defined entrypoint.

This means duplication of the codebase / python executable bot for most applications this should be a negligible overhead.

Previously discussed in #75 (comment)

I'm trying to walk through the tutorial. Here's the bash history:
2001 mkdir tutorial
2002 cd tutorial/
2003 python3.5 -m venv venv
2004 . venv/bin/activate
2005 pip install briefcase
2006 apt-get install python3-gi gir1.2-webkit2-3.0
2007 sudo apt-get install python3-gi gir1.2-webkit2-3.0
2008 pip install --upgrade pip
2009 cookiecutter https://github.com/pybee/briefcase-template
2010 cd helloworld/
2011 vir helloworld/app.py
2012 python setup.py linux -s

All commands were successful until the final one. setup produced a cascade of errors, the first one being:

Installation complete.

from ._gi import _gobject
ImportError: No module named 'gi._gi'

It indicates that other exceptions occurred during the handling of that one, but I suspect those are not relevant.

I initially attempted this with Py3.4 which failed. I saw in a different issue that I would likely be better off with 3.5. I built and installed 3.5 and that's what's running in the VM. I also had used mkproject instead of creating the venv manually as shown in the example. I backed that out and started a new project doing it the manual way (as shown above).

Looking at the /helloworld/linux/app_packages/gi/init.py file, there is an import there
from ._gi import _gobject
There is not a _gi directory in the gi dir. There are two files which might be related:
_gi_cairo.cpython-34m-i386-linux-gnu.so
_gi.cpython-34m-i386-linux-gnu.so

I'm suspecting that there's some flotsam left over from either the 3.4 attempt or the mkproject attempt that is causing me problems, but I'm not seeing how those would produce the linux directory (in a new, clean subdir) without the required module.

NOTE: just to be complete. I went back and redid the steps after I manually removed the ~/.cookiecutters/ briefcase-template and Python-Linux-template directories. Same result.

Thanks for any help!
