Newb wondering what I've screwed up with my Python RegEx

I’m a Rubyist by day (with three years of Python once upon a time) and I’m struggling with getting the following task to only run once with the regular expression below. According to Pythex it should be matching (see: http://bit.ly/1dGw2GV).

My task looks as follows and should add the following line to ~/.bashrc if it doesn’t already exist:

export PATH=${STOW}/…/bin:${PATH}

  • name: Ensure $STOW is in $PATH
    lineinfile:
    dest={{HOME.stdout}}/.bashrc
    regexp=“^export PATH=${STOW}.*”
    line=“export PATH=${STOW}/…/bin:${PATH}”
    state=present
    insertafter=EOF
    create=True

With this version of it the line is added properly, with each and every run instead of just the initial run even though I get a full match on pythex…

I’m wondering if I should be testing against a different regular expression parser (I realize there are slight variations between languages) or if I’m just missing something blatantly obvious?

Any help appreciated,

Steven

PS - “${STOW}” in the above is a previously exported environment variable, not an attempt to insert an ansible variable of some kind.
