This one looks easy to fix. YAML thought it was looking for the start of a

meant to be an ansible template evaluation instead, so we have to give the
parser a small hint that we wanted a string instead. The solution here is to
just quote the entire value.

app_path: {{ base_path }}/foo
It should be written as:
app_path: "{{ base_path }}/foo"

with_items:

This one looks easy to fix. There seems to be an extra unquoted colon in the line

entire line after the first colon.
For instance, if the original line was:
copy: src=file.txt dest=/path/filename:with_colon.txt
It can be written as:
copy: src=file.txt dest='/path/filename:with_colon.txt'

Used to insert chunks of code into modules before transfer rather than
doing regular python imports. This allows for more efficient transfer in
a non-bootstrapping scenario by not moving extra files over the wire and
also takes care of embedding arguments in the transferred modules.
This version is done in such a way that local imports can still be
used in the module code, so IDEs don't have to be aware of what is going on.
Example:
from ansible.module_utils.basic import *
... will result in the insertion of basic.py into the module
from the module_utils/ directory in the source tree.
All modules are required to import at least basic, though there will also
be other snippets.
For powershell, there's equivalent conventions like this:
# POWERSHELL_COMMON
which results in the inclusion of the common code from powershell.ps1

### TODO: Optimization ideas if this code is actually a source of slowness:
# * Fix comment stripping: Currently doesn't preserve shebangs and encoding info (but we unconditionally add encoding info)
# * Use pyminifier if installed
# * comment stripping/pyminifier needs to have config setting to turn it
# off for debugging purposes (goes along with keep remote but should be
# separate otherwise users wouldn't be able to get info on what the
# minifier output)
# * Only split into lines and recombine into strings once
# * Cache the modified module? If only the args are different and we do
# that as the last step we could cache sll the work up to that point.

Role Name
=========
A brief description of the role goes here.
Requirements
------------
Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
Role Variables
--------------
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
Dependencies
------------
A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
Example Playbook
----------------
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
- hosts: servers
roles:
- { role: username.rolename, x: 42 }
License
-------
BSD
Author Information
------------------
An optional section for the role authors to include contact information, or a website (HTML is not allowed).

The Replacer is used to insert chunks of code into modules before
transfer. Rather than doing classical python imports, this allows for more
efficient transfer in a no-bootstrapping scenario by not moving extra files
over the wire, and also takes care of embedding arguments in the transferred
modules.
This version is done in such a way that local imports can still be
used in the module code, so IDEs don't have to be aware of what is going on.
Example:
from ansible.module_utils.basic import *
... will result in the insertion basic.py into the module
from the module_utils/ directory in the source tree.
All modules are required to import at least basic, though there will also
be other snippets.
