Highlight code without transient file using pbcopy
I've been creating a LOT of code slides in keynote recently. I'd like to have it highlight and also show up as text rather than a screenshot. And I want it to be EASY!
Look no further. Copy the code snippet you'd like to highlight then run:
pbpaste | highlight -O rtf --src-lang js --style solarized-dark --font Monaco | pbcopy
This will pass your current paste buffer to highlight, format it, then put it back into your paste buffer for immediate paste into Keynote (or where ever).
Too easy!
Check highlight --help for more options and languages.
