I mentioned in my previous post that I somehow had ended up with a non-working org2blog installation. My suspicion is that this was triggered by my pinning of the htmlize package to the “wrong” repo. I had it pinned to marmalade rather than melpa-stable, and marmalade had an old version of htmlize (1.39, from memory). The fact that marmalade is erroring out with an expired certificate is most likely a sign that I need to stop using it. Anyway, re-pinning htmlize to melpa-stable unclogged that particular problem and the updated org2blog flowed onto my machine.
As a bonus, I ended up following the instructions for installing org2blog v1.1.0. While that version is not yet available on melpa-stable, it exposed me to use-package, which is something I’ve been meaning to look at but haven’t got around to so far. A quick glance at the docs – which is all I’ve had time for so far – suggests that I really need to look at use-package in depth and possibly update my .emacs to make use of it rather than continuing to maintain the home grown package installation wrapper I’ve been using for the last few years.
Either way, I’m happy to be able to blog from Emacs again rather than having to suffer WordPress’s built-in editor.
