From 52cbcb78ed100ce2d7ac28d98f6694a77a6a1235 Mon Sep 17 00:00:00 2001 From: Bert Wesarg Date: Wed, 20 Oct 2010 22:17:46 +0200 Subject: [PATCH] provide a global temporary directory MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The standard procedure 'tmp=mktemp; trap "rm $tmp" 0' was broken with the introduction of the pager. Which overwrites the trap itself to close and remove the pager fifo. Now tg provides a temp playground and all other temp files should be created inside this directory and only this directory will be removed with the exit trap. setup_pager still overwrites the trap, but keeps the rm command from the global temp directory. To simplify this the new function get_temp() is provided.
