pandoc is becoming a hammer...

[avidseeker]

... and everything looks like a nail.

TITLE=$(pandoc -t rst f.md -o /dev/null \
	-L <(echo "function Meta(m) print(pandoc.utils.stringify(m.title)) end")
)

$ pandoc-lua <(echo "print(2 * math.pi^2)")

If you're going to use a hammer, why beat around the bush?

• Do you need the shell echo? No.
• Do you need the Lua print? No.
• Do you need double quotes when singles will do? No.
• Do you need the parenthesis? No.
• Do you need so many spaces? No.

Just whack the nail.

$ pandoc lua <<< '2*math.pi^2'
