I am writing a desktop application in Python (3.4) on Linux using Qt (4.8) and PyQt.
Is there a way to use/import Okular's pdf view functionality as a widget? If yes, how?
This works for me:
import sys
from PyKDE4.kdecore import ki18n, KAboutData, KCmdLineArgs
from PyKDE4.kdecore import KLibLoader as ll
from PyKDE4.kdeui import KApplication
import PyKDE4.kparts as kp
appName = "KApplication"
catalog = ""
programName = ki18n ("KApplication")
version = "1.0"
description = ki18n ("KApplication")
license = KAboutData.License_GPL
copyright = ki18n ("(c) 2007 John Doe")
text = ki18n ("none")
homePage = "www.johndoe.com"
bugEmail = "johndoe#nowhere.com "
aboutData = KAboutData(
appName, catalog, programName, version, description,
license, copyright, text, homePage, bugEmail
)
KCmdLineArgs.init(sys.argv, aboutData)
app = KApplication()
win = kp.KParts.MainWindow()
okupart = ll.self().factory('okularpart').create()
win.setCentralWidget(okupart.widget())
win.show()
app.exec_()
pykde could provide the required functionality. I have not figured out how, though.
Get the latest version of pykde:
git clone git://anongit.kde.org/pykde4

Building it required PyQt4 and CMAKE. Some linux distributions ship an outdated version of FindPyQt.py (causing an error along the lines of Python importerror : pyqtconfig). A functional one can be found here:

Place it in /usr/share/kde4/apps/cmake/modules/
For compiling your UI files into Python code, use pykdeuic4 instead of pyuic4:

I have a requirements.txt file that I'm using with Travis-CI. It seems silly to duplicate the requirements in both requirements.txt and setup.py, so I was hoping to pass a file handle to the install_requires kwarg in setuptools.setup.
Is this possible? If so, how should I go about doing it?
Here is my requirements.txt file:
guessit>=0.5.2
tvdb_api>=1.8.2
hachoir-metadata>=1.3.3
hachoir-core>=1.3.3
hachoir-parser>=1.3.4
On the face of it, it does seem that requirements.txt and setup.py are silly duplicates, but it's important to understand that while the form is similar, the intended function is very different.
The goal of a package author, when specifying dependencies, is to say "wherever you install this package, these are the other packages you need, in order for this package to work."
In contrast, the deployment author (which may be the same person at a different time) has a different job, in that they say "here's the list of packages that we've gathered together and tested and that I now need to install".
The package author writes for a wide variety of scenarios, because they're putting their work out there to be used in ways they may not know about, and have no way of knowing what packages will be installed alongside their package. In order to be a good neighbor and avoid dependency version conflicts with other packages, they need to specify as wide a range of dependency versions as can possibly work. This is what install_requires in setup.py does.
The deployment author writes for a very different, very specific goal: a single instance of an installed application or service, installed on a particular computer. In order to precisely control a deployment, and be sure that the right packages are tested and deployed, the deployment author must specify the exact version and source-location of every package to be installed, including dependencies and dependency's dependencies. With this spec, a deployment can be repeatably applied to several machines, or tested on a test machine, and the deployment author can be confident that the same packages are deployed every time. This is what a requirements.txt does.
So you can see that, while they both look like a big list of packages and versions, these two things have very different jobs. And it's definitely easy to mix this up and get it wrong! But the right way to think about this is that requirements.txt is an "answer" to the "question" posed by the requirements in all the various setup.py package files. Rather than write it by hand, it's often generated by telling pip to look at all the setup.py files in a set of desired packages, find a set of packages that it thinks fits all the requirements, and then, after they're installed, "freeze" that list of packages into a text file (this is where the pip freeze name comes from).
So the takeaway:
setup.py should declare the loosest possible dependency versions that are still workable. Its job is to say what a particular package can work with.
requirements.txt is a deployment manifest that defines an entire installation job, and shouldn't be thought of as tied to any one package. Its job is to declare an exhaustive list of all the necessary packages to make a deployment work.
Because these two things have such different content and reasons for existing, it's not feasible to simply copy one into the other.
References:
install_requires vs Requirements files from the Python packaging user guide.
You can flip it around and list the dependencies in setup.py and have a single character — a dot . — in requirements.txt instead.
Alternatively, even if not advised, it is still possible to parse the requirements.txt file (if it doesn't refer any external requirements by URL) with the following hack (tested with pip 9.0.1):
install_reqs = parse_requirements('requirements.txt', session='hack')
This doesn't filter environment markers though.
In old versions of pip, more specifically older than 6.0, there is a public API that can be used to achieve this. A requirement file can contain comments (#) and can include some other files (--requirement or -r). Thus, if you really want to parse a requirements.txt you can use the pip parser:
from pip.req import parse_requirements
# parse_requirements() returns generator of pip.req.InstallRequirement objects
install_reqs = parse_requirements(<requirements_path>)
# reqs is a list of requirement
# e.g. ['django==1.5.1', 'mezzanine==1.4.6']
reqs = [str(ir.req) for ir in install_reqs]
setup(
...
install_requires=reqs
)
It can't take a file handle. The install_requires argument can only be a string or a list of strings.
You can, of course, read your file in the setup script and pass it as a list of strings to install_requires.
import os
from setuptools import setup
with open('requirements.txt') as f:
required = f.read().splitlines()
setup(...
install_requires=required,
...)
Requirements files use an expanded pip format, which is only useful if you need to complement your setup.py with stronger constraints, for example specifying the exact urls some of the dependencies must come from, or the output of pip freeze to freeze the entire package set to known-working versions. If you don't need the extra constraints, use only a setup.py. If you feel like you really need to ship a requirements.txt anyway, you can make it a single line:
.
It will be valid and refer exactly to the contents of the setup.py that is in the same directory.
While not an exact answer to the question, I recommend Donald Stufft's blog post at https://caremad.io/2013/07/setup-vs-requirement/ for a good take on this problem. I've been using it to great success.
In short, requirements.txt is not a setup.py alternative, but a deployment complement. Keep an appropriate abstraction of package dependencies in setup.py. Set requirements.txt or more of 'em to fetch specific versions of package dependencies for development, testing, or production.
E.g. with packages included in the repo under deps/:
# fetch specific dependencies
--no-index
--find-links deps/
# install package
# NOTE: -e . for editable mode
.
pip executes package's setup.py and installs the specific versions of dependencies declared in install_requires. There's no duplicity and the purpose of both artifacts is preserved.
Using parse_requirements is problematic because the pip API isn't publicly documented and supported. In pip 1.6, that function is actually moving, so existing uses of it are likely to break.
A more reliable way to eliminate duplication between setup.py and requirements.txt is to specific your dependencies in setup.py and then put -e . into your requirements.txt file. Some information from one of the pip developers about why that's a better way to go is available here: https://caremad.io/blog/setup-vs-requirement/
First, I believe parsing requirements.txt to fill the list of dependencies in package metadata is not a good idea. The requirements.txt file and the list of "install dependencies" are two different concepts, they are not interchangeable. It should be the other way around, the list of dependencies in package metadata should be considered as some kind of source of truth, and files such as requirements.txt should be generated from there. For example with a tool such as pip-compile. See the notes at the bottom of this answer.
But everyone has different needs, that lead to different workflows. So with that said... There are 3 possibilities to handle this, depending on where you want your project's package metadata to be written: pyproject.toml, setup.cfg, or setup.py.
Words of caution!
If you insist on having the list of dependencies in package metadata be read from a requirements.txt file then make sure that this requirements.txt file is included in the "source distribution" (sdist) otherwise installation will fail, for obvious reasons.
These techniques will work only for simple requirements.txt files. See Requirements parsing in the documentation page for pkg_resources to get details about what is handled. In short, each line should be a valid PEP 508 requirement. Notations that are really specific to pip are not supported and it will cause a failure.
pyproject.toml
[project]
# ...
dynamic = ["dependencies"]
[tool.setuptools.dynamic]
# ...
dependencies = requirements.txt
setup.cfg
Since setuptools version 62.6 it is possible to write something like this in setup.cfg:
[options]
install_requires = file: requirements.txt
setup.py
It is possible to parse a relatively simple requirements.txt file from a setuptools setup.py script without pip. The setuptools project already contains necessary tools in its top level package pkg_resources.
It could more or less look like this:
#!/usr/bin/env python
import pathlib
import pkg_resources
import setuptools
with pathlib.Path('requirements.txt').open() as requirements_txt:
install_requires = [
str(requirement)
for requirement
in pkg_resources.parse_requirements(requirements_txt)
]
setuptools.setup(
install_requires=install_requires,
)

Most of the other answers above don't work with the current version of pip's API. Here is the correct* way to do it with the current version of pip (6.0.8 at the time of writing, also worked in 7.1.2. You can check your version with pip -V).
from pip.req import parse_requirements
from pip.download import PipSession
install_reqs = parse_requirements(<requirements_path>, session=PipSession())
reqs = [str(ir.req) for ir in install_reqs]
setup(
...
install_requires=reqs
....
)
* Correct, in that it is the way to use parse_requirements with the current pip. It still probably isn't the best way to do it, since, as posters above said, pip doesn't really maintain an API.
Install the current package in Travis. This avoids the use of a requirements.txt file.
For example:
language: python
python:
- "2.7"
- "2.6"
install:
- pip install -q -e .
script:
- python runtests.py
from pip.req import parse_requirements did not work for me and I think it's for the blank lines in my requirements.txt, but this function does work
def parse_requirements(requirements):
with open(requirements) as f:
return [l.strip('\n') for l in f if l.strip('\n') and not l.startswith('#')]
reqs = parse_requirements(<requirements_path>)
setup(
...
install_requires=reqs,
...
)
The following interface became deprecated in pip 10:
from pip.req import parse_requirements
from pip.download import PipSession
So I switched it just to simple text parsing:
with open('requirements.txt', 'r') as f:
install_reqs = [
s for s in [
line.split('#', 1)[0].strip(' \t\n') for line in f
] if s != ''
]
BEWARE OF parse_requirements BEHAVIOUR!
Please note that pip.req.parse_requirements will change underscores to dashes. This was enraging me for a few days before I discovered it. Example demonstrating:
from pip.req import parse_requirements # tested with v.1.4.1
reqs = '''
example_with_underscores
example-with-dashes
'''
with open('requirements.txt', 'w') as f:
f.write(reqs)
req_deps = parse_requirements('requirements.txt')
result = [str(ir.req) for ir in req_deps if ir.req is not None]
print result
produces
['example-with-underscores', 'example-with-dashes']
If you don't want to force your users to install pip, you can emulate its behavior with this:
import sys
from os import path as p
try:
from setuptools import setup, find_packages
except ImportError:
from distutils.core import setup, find_packages
def read(filename, parent=None):
parent = (parent or __file__)
try:
with open(p.join(p.dirname(parent), filename)) as f:
return f.read()
except IOError:
return ''
def parse_requirements(filename, parent=None):
parent = (parent or __file__)
filepath = p.join(p.dirname(parent), filename)
content = read(filename, parent)
for line_number, line in enumerate(content.splitlines(), 1):
candidate = line.strip()
if candidate.startswith('-r'):
for item in parse_requirements(candidate[2:].strip(), filepath):
yield item
else:
yield candidate
setup(
...
install_requires=list(parse_requirements('requirements.txt'))
)
I created a reusable function for this. It actually parses an entire directory of requirements files and sets them to extras_require.

Cross posting my answer from this SO question for another simple, pip version proof solution.
try: # for pip >= 10
from pip._internal.req import parse_requirements
from pip._internal.download import PipSession
except ImportError: # for pip <= 9.0.3
from pip.req import parse_requirements
from pip.download import PipSession
requirements = parse_requirements(os.path.join(os.path.dirname(__file__), 'requirements.txt'), session=PipSession())
if __name__ == '__main__':
setup(
...
install_requires=[str(requirement.req) for requirement in requirements],
...
)
Then just throw in all your requirements under requirements.txt under project root directory.
Yet another parse_requirements hack that also parses environment markers into extras_require:
from collections import defaultdict
from pip.req import parse_requirements
requirements = []
extras = defaultdict(list)
for r in parse_requirements('requirements.txt', session='hack'):
if r.markers:
extras[':' + str(r.markers)].append(str(r.req))
else:
requirements.append(str(r.req))
setup(
...,
install_requires=requirements,
extras_require=extras
)
It should support both sdist and binary dists.
As stated by others, parse_requirements has several shortcomings, so this is not what you should do on public projects, but it may suffice for internal/personal projects.
I did this:
import re
def requirements(filename):
with open(filename) as f:
ll = f.read().splitlines()
d = {}
for l in ll:
k, v = re.split(r'==|>=', l)
d[k] = v
return d
def packageInfo():
try:
from pip._internal.operations import freeze
except ImportError:
from pip.operations import freeze
d = {}
for kv in freeze.freeze():
k, v = re.split(r'==|>=', kv)
d[k] = v
return d
req = getpackver('requirements.txt')
pkginfo = packageInfo()
for k, v in req.items():
print(f'{k:<16}: {v:<6} -> {pkginfo[k]}')
Here is a complete hack (tested with pip 9.0.1) based on Romain's answer that parses requirements.txt and filters it according to current environment markers:
from pip.req import parse_requirements
requirements = []
for r in parse_requirements('requirements.txt', session='hack'):
# check markers, such as
#
# rope_py3k ; python_version >= '3.0'
#
if r.match_markers():
requirements.append(str(r.req))
print(requirements)
We use py2app extensively at our facility to produce self contained .app packages for easy internal deployment without dependency issues. Something I noticed recently, and have no idea how it began, is that when building an .app, py2app started including the .git directory of our main library.
commonLib, for instance, is our root python library package, which is a git repo. Under this package are the various subpackages such as database, utility, etc.
commonLib/
|- .git/ # because commonLib is a git repo
|- __init__.py
|- database/
|- __init__.py
|- utility/
|- __init__.py
# ... etc
In a given project, say Foo, we will do imports like from commonLib import xyz to use our common packages. Building via py2app looks something like: python setup.py py2app
So the recent issue I am seeing is that when building an app for project Foo, I will see it include everything in commonLib/.git/ into the app, which is extra bloat. py2app has an excludes option but that only seems to be for python modules. I cant quite figure out what it would take to exclude the .git subdir, or in fact, what is causing it to be included in the first place.
Has anyone experienced this when using a python package import that is a git repo?
Nothing has changed in our setup.py files for each project, and commonLib has always been a git repo. So the only thing I can think of being a variable is the version of py2app and its deps which have obviously been upgraded over time.
Edit
I'm using the latest py2app 0.6.4 as of right now. Also, my setup.py was first generated from py2applet a while back, but has been hand configured since and copied over as a template for every new project. I am using PyQt4/sip for every single one of these projects, so it also makes me wonder if its an issue with one of the recipes?
Update
From the first answer, I tried to fix this using various combinations of exclude_package_data settings. Nothing seems to force the .git directory to become excluded. Here is a sample of what my setup.py files generally look like:
from setuptools import setup
from myApp import VERSION
appname = 'MyApp'
APP = ['myApp.py']
DATA_FILES = []
OPTIONS = {
'includes': 'atexit, sip, PyQt4.QtCore, PyQt4.QtGui',
'strip': True,
'iconfile':'ui/myApp.icns',
'resources':['src/myApp.png'],
'plist':{
'CFBundleIconFile':'ui/myApp.icns',
'CFBundleIdentifier':'com.company.myApp',
'CFBundleGetInfoString': appname,
'CFBundleVersion' : VERSION,
'CFBundleShortVersionString' : VERSION
}
}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
I have tried things like:
setup(
...
exclude_package_data = { 'commonLib': ['.git'] },
#exclude_package_data = { '': ['.git'] },
#exclude_package_data = { 'commonLib/.git/': ['*'] },
#exclude_package_data = { '.git': ['*'] },
...
)
Update #2
I have posted my own answer which does a monkeypatch on distutils. Its ugly and not preferred, but until someone can offer me a better solution, I guess this is what I have.
I am adding an answer to my own question, to document the only thing I have found to work thus far. My approach was to monkeypatch distutils to ignore certain patterns when creating a directory or copying a file. This is really not what I wanted to do, but like I said, its the only thing that works so far.
## setup.py ##
import re
# file_util has to come first because dir_util uses it
from distutils import file_util, dir_util
def wrapper(fn):
def wrapped(src, *args, **kwargs):
if not re.search(r'/\.git/?', src):
fn(src, *args, **kwargs)
return wrapped
file_util.copy_file = wrapper(file_util.copy_file)
dir_util.mkpath = wrapper(dir_util.mkpath)
# now import setuptools so it uses the monkeypatched methods
from setuptools import setup
Hopefully someone will comment on this and tell me a higher level approach to avoid doing this. But as of now, I will probably wrap this into a utility method like exclude_data_patterns(re_pattern) to be reused in my projects.
I can see two options for excluding the .git directory.
Build the application from a 'clean' checkout of the code. When deploying a new version, we always build from a fresh svn export based on a tag to ensure we don't pick up spurious changes/files. You could try the equivalent here - although the git equivalent seems somewhat more involved.
Modify the setup.py file to massage the files included in the application. This might be done using the exclude_package_data functionality as described in the docs, or build the list of data_files and pass it to setup.
As for why it has suddenly started happening, knowing the version of py2app you are using might help, as will knowing the contents of your setup.py and perhaps how this was made (by hand or using py2applet).
I have a similar experience with Pyinstaller, so I'm not sure it applies directly.
Pyinstaller creates a "manifest" of all files to be included in the distribution, before running the export process. You could "massage" this manifest, as per Mark's second suggestion, to exclude any files you want. Including anything within .git or .git itself.
In the end, I stuck with checking out my code before producing a binary as there was more than just .git being bloat (such as UML documents and raw resource files for Qt). A checkout guaranteed a clean result and I experienced no issues automating that process along with the process of creating the installer for the binary.
There is a good answer to this, but I have a more elaborate answer to solve the problem mentioned here with a white-list approach. To have the monkey patch also work for packages outside site-packages.zip I had to monkey patch also copy_tree (because it imports copy_file inside its function), this helps in making a standalone application.
In addition, I create a white-list recipe to mark certain packages zip-unsafe. The approach makes it easy to add filters other than white-list.
