In Ansible, how do I add a line to the end of a file?

Question

I would expect this to be pretty simple. I'm using the lineinfile module like so:

- name: Update bashrc for PythonBrew for foo user   lineinfile:     dest=/home/foo/.bashrc     backup=yes     line="[[ -s ${pythonbrew.bashrc_path} ]] && source ${pythonbrew.bashrc_path}"     owner=foo     regexp='^'     state=present     insertafter=EOF     create=True 

The problem I'm having is that it's replacing the last line in the file (which is fi) with my new line rather than appending the line. This produces a syntax error.

Do I have the parameters correct? I've tried setting regexp to both '^' and '' (blank). Is there another way to go about this?

I'm using Ansible 1.3.3.

The Ansible discussion group helped get me sorted out on this. The problem is the regexp parameter.

Since I only want the line appended to the file once, I need the regexp to match the line as closely as possible. This is complicated in my case by the fact that my line includes variables. But, assuming the line started [[ -s $HOME/.pythonbrew, I found the following to be sufficient:

- name: Update bashrc for PythonBrew for foo user   lineinfile:     dest: /home/foo/.bashrc     line: "[[ -s ${pythonbrew.bashrc_path} ]] && source ${pythonbrew.bashrc_path}"     regexp: "^\[\[ -s \\$HOME/\.pythonbrew"     owner: foo     state: present     insertafter: EOF     create: True

Apparently ansible has matured and now (version >2.4.0) according to the documentation, The defaults when only the line is specified will append a given line to the destination file:

    - name: Update bashrc for PythonBrew for foo user       lineinfile:         dest: /home/foo/.bashrc         line: "[[ -s ${pythonbrew.bashrc_path} ]] && source {pythonbrew.bashrc_path}"         owner: foo
