Re: [9fans] regexp metacharacter difficulty inside grap

[Jeff Sickel <jas@corpus-callosum.com>]

It's good to learn new things every day.  Grap strips the ')' out, no need for all that funny sh {} business:

		if "$1" == "#" then {
			if "$2" == "(Yo" then {
				print sprintf("Yo was %f", yo)
				yo = $3
				print sprintf("Yo is %f", yo)
			}
		}

success!

mk
Creating t.ps...
	Yo was 8.579000
	Yo is 4.953400
	Yo was 4.953400
	Yo is 4.953400
Creating t.pdf...


Now to find out why the fonts on Plan 9 create nice print outs but really awkward text inside of PDF files.  My theory is that gs is not stuffing all of the fonts in as it should.
