I have recently ported the array language Klong, a pet project of mine, to Plan 9. Everything works fine, but I came across the following behavior of page(1), which I though was strange:
Klong has a built-in function plotter, which uses ghostscript as a back end, so it writes Postscript code to a file and then runs page -b file which displays the graph just fine, but then page just sits there and does not react to any keyboard or mouse commands. I have to open another term and kill it. However, when the Klong process runs gs '-sOutputFile=-' -dBATCH -dNOPAUSE -q file | page -b everything works as expected. So the problem is solved, but I'm curious as to what causes page to hang in the first case. Any ideas? -- Nils M Holm < n m h @ t 3 x . o r g > www.t3x.org
