* template: Add integration tests for `lstrip_blocks' Signed-off-by: Alex Tsitsimpis <alextsi@arrikto.com> * template: Fix passing `trim_blocks' inline Fix passing `trim_blocks' option to the template module as inline argument. Previously passing the `trim_blocks' option inline instead of using the YAML dictionary format resulted in it always being set to `True', even if `trim_blocks=False' was used. Signed-off-by: Alex Tsitsimpis <alextsi@arrikto.com> * template: Add option to `lstrip_blocks' Add option to set `lstrip_blocks' when using the template module to render Jinja templates. The Jinja documentation suggests that `trim_blocks' and `lstrip_blocks' is a great combination and the template module already provides an option for `trim_blocks'. Note that although `trim_blocks' in Ansible is enabled by default since version 2.4, in order to avoid breaking things keep `lstrip_blocks' disabled by default. Maybe in a future version it could be enabled by default. This seems to address issue #10725 in a more appropriate way than the suggested. Signed-off-by: Alex Tsitsimpis <alextsi@arrikto.com> * template: Add integration tests for `trim_blocks' Signed-off-by: Alex Tsitsimpis <alextsi@arrikto.com> * template: Check Jinja2 support for `lstrip_blocks' Since the `lstrip_blocks' option was added in Jinja2 version 2.7, raise an exception when `lstrip_blocks' is set but Jinja2 does not support it. Check support for `lstrip_blocks' option by checking `jinja2.defaults' for `LSTRIP_BLOCKS' and do not use `jinja2.__version__' because the latter is set to `unknown' in some cases, perhaps due to bug in `pkg_resources' in Python 2.6.6. Also update option description to state that Jinja2 version >=2.7 is required. Signed-off-by: Alex Tsitsimpis <alextsi@arrikto.com> |

Ansible
Ansible is a radically simple IT automation system. It handles configuration-management, application deployment, cloud provisioning, ad-hoc task-execution, and multinode orchestration - including trivializing things like zero-downtime rolling updates with load balancers.
Read the documentation and more at https://ansible.com/
You can find installation instructions here for a variety of platforms. Most users should probably install a released version of Ansible from pip, a package manager or our release repository. Officially supported builds of Ansible are also available. Some power users run directly from the development branch - while significant efforts are made to ensure that devel is reasonably stable, you're more likely to encounter breaking changes when running Ansible this way.
Design Principles
- Have a dead simple setup process and a minimal learning curve
- Manage machines very quickly and in parallel
- Avoid custom-agents and additional open ports, be agentless by leveraging the existing SSH daemon
- Describe infrastructure in a language that is both machine and human friendly
- Focus on security and easy auditability/review/rewriting of content
- Manage new remote machines instantly, without bootstrapping any software
- Allow module development in any dynamic language, not just Python
- Be usable as non-root
- Be the easiest IT automation system to use, ever.
Get Involved
- Read Community Information for all kinds of ways to contribute to and interact with the project, including mailing list information and how to submit bug reports and code to Ansible.
- All code submissions are done through pull requests. Take care to make sure no merge commits are in the submission, and use
git rebasevsgit mergefor this reason. If submitting a large code change (other than modules), it's probably a good idea to join ansible-devel and talk about what you would like to do or add first and to avoid duplicate efforts. This not only helps everyone know what's going on, it also helps save time and effort if we decide some changes are needed. - Users list: ansible-project

Branch Info
- Releases are named after Led Zeppelin songs. (Releases prior to 2.0 were named after Van Halen songs.)
- The devel branch corresponds to the release actively under development.
- Various release-X.Y branches exist for previous releases.
- We'd love to have your contributions, read Community Information for notes on how to get started.
