New release and some new features! Conan 1.6 comes with many small improvements around tooling and process execution inside recipes as well as with small additions to the command line.
New parameters for self.run()
Having a look at many many recipes we realized that setting environment variables such as
DYLD_LIBRARY_PATH to launch packaged apps is a
very recurrent use case. There were already some tools to help with the process but still there was a nasty repeatedly used bunch of code
lines usually in test_package:
def test(self): with tools.environment_append(RunEnvironment(self).vars): bin_path = os.path.join("bin", "example") if self.settings.os == "Windows": self.run(bin_path) elif self.settings.os == "Macos": self.run("DYLD_LIBRARY_PATH=%s %s" % (os.environ.get('DYLD_LIBRARY_PATH', ''), bin_path)) else: self.run("LD_LIBRARY_PATH=%s %s" % (os.environ.get('LD_LIBRARY_PATH', ''), bin_path))
def test(self): bin_path = os.path.join("bin", "example") self.run(bin_path, run_environment=True)
This release has been very much about improvements to the Conan tools and new additions as mentioned above with
We have new
dos2unix() to convert between LF and CRLF line endings.
There were some improvements in
tools.get() with parameters
filename, to download files with a name that cannot be deduced from URL,
keep_permissions, to propagate the flag to
tools.unzip() we have introduced support for XZ extensions. This would only be available for Python 3 users and starts the
journey towards Python 2 deprecation as there is no support to implement such new features.
Finally we continued improving the
tools.Git(), this time to allow capturing the current branch with
get_branch() and current commit
Go and check all the new changes in the tools section.
Small additions to commands
We included new
--raw flag to
conan remote list to display remotes in the same way they are configured in the registry. You can copy
and paste the output into your remotes.txt file to use
conan config install feature!
config install, it has a new
--type "git" flag to indicate installation should be done cloning a git repository from
the URL provided. This is handy for example if you are working with Microsoft Team Foundation Server TFS git repositories.
conan build --test was added together with
should_test attribute in the conanfile as a logic step to
control the test stage
- LLVM toolsets for Visual Studio has been included in settings.yml.
- We have improved our pyinstaller to include the Python dependencies and improved the deb installer for distros such as Debian 9.
