I’m prepping talks for a few conferences. I think I’ve got my workflow down for syntax highlighting slides in Keynote on my Mac.

1. pip install pygments, not in a virtualenv but in your default Python.

2. Make a Bash script like:

/usr/local/bin/pygmentize -f rtf -O "style=friendly,fontface=Courier Bold" "$1" | pbcopy

Make sure it’s chmod’ed executable and on your path. Now you can do pyg myscript.py and then paste the syntax-highlighted code into Keynote. The result is pretty nice; at some point I may make a Pygments style optimized for presentations:

3. In Keynote, turn off all auto-correction:

4. Bonus round: PyCharm integration. In PyCharm’s preferences, choose “External Tools,” hit the “+”, and fill out the dialog like so:

PyCharm Edit Tool

You can leave “Open Console” checked while you’re getting things working.

Finally, in the “Keymap” section of PyCharm’s vast settings dialog, search for “pyg” in the filter box, right-click on it, and assign a hotkey of your choice to the tool. I chose Command-Y because it was bound to some weird function I don’t use.

PyCharm assign hotkey

Now whenever you’re editing a file in PyCharm, you can save it and hit Command-Y, then switch to Keynote and paste.

Readers, if anyone can tell me how to adjust the default font size in Pygments for RTF output specifically, that’d be great.
